what role does medicinal chemists play

what role does medicinal chemists play in drug research so let me just give you

in drug research so let me just give you

in drug research so let me just give you a very very crude background of what

a very very crude background of what

a very very crude background of what research is about the drug research

research is about the drug research

research is about the drug research typically can be divided to two stages

typically can be divided to two stages

typically can be divided to two stages the first one will be what we call a

the first one will be what we call a

the first one will be what we call a trap discovery and this is a stage a

trap discovery and this is a stage a

trap discovery and this is a stage a compound of interest which can

compound of interest which can

compound of interest which can potentially act as a drug is identified

potentially act as a drug is identified

potentially act as a drug is identified the later stage is what we call drug

the later stage is what we call drug

the later stage is what we call drug development and this is a stage where

development and this is a stage where

development and this is a stage where all preclinical and for I as well as

all preclinical and for I as well as

all preclinical and for I as well as humans will be carried out medicinal

humans will be carried out medicinal

humans will be carried out medicinal chemists are properly involved in drug

chemists are properly involved in drug

chemists are properly involved in drug discovery stage in this drug discovery

discovery stage in this drug discovery

discovery stage in this drug discovery stage what the medicinal chemists did to

stage what the medicinal chemists did to

stage what the medicinal chemists did to synthesize purify characterize and

synthesize purify characterize and

synthesize purify characterize and compound so it’s pretty boring you

compound so it’s pretty boring you

compound so it’s pretty boring you myself

myself

myself right so huh but they played an

right so huh but they played an

right so huh but they played an important role framing the hypothesis of

important role framing the hypothesis of

important role framing the hypothesis of a new track project so they have an

a new track project so they have an

a new track project so they have an important role to play as after a hit

important role to play as after a hit

important role to play as after a hit compound has been identified hip

compound has been identified hip

compound has been identified hip compound basically means a compound

compound basically means a compound

compound basically means a compound which is pal

which is pal

which is pal it is a medicine chemist who tends

it is a medicine chemist who tends

it is a medicine chemist who tends decide which part of the molecule change

decide which part of the molecule change

decide which part of the molecule change or modify in order to enhance or

or modify in order to enhance or

or modify in order to enhance or maximize its activity and during this

maximize its activity and during this

maximize its activity and during this fine-tuning process a project may feel

fine-tuning process a project may feel

fine-tuning process a project may feel drugs that we have today exist is due in

drugs that we have today exist is due in

drugs that we have today exist is due in part to medicine chemists can tirelessly

part to medicine chemists can tirelessly

part to medicine chemists can tirelessly to solve one problem and over the years

to solve one problem and over the years

to solve one problem and over the years many new approaches in drug discovery

many new approaches in drug discovery

many new approaches in drug discovery has been made and one of the most

has been made and one of the most

has been made and one of the most significant that I want to share with

significant that I want to share with

significant that I want to share with you is the emergence of biologics so

you is the emergence of biologics so

you is the emergence of biologics so biologics

biologics

biologics eclis engineer products based on living

eclis engineer products based on living

eclis engineer products based on living organism the proposition of using

organism the proposition of using

organism the proposition of using biologics to true or to cure diseases is

biologics to true or to cure diseases is

biologics to true or to cure diseases is about just imagine such as cancer using

about just imagine such as cancer using

about just imagine such as cancer using peptides or proteins antibodies or even

peptides or proteins antibodies or even

peptides or proteins antibodies or even cells so very recently there are

cells so very recently there are

cells so very recently there are researchers who has been using t-cells

researchers who has been using t-cells

researchers who has been using t-cells in trying to cure cancer

in trying to cure cancer

in trying to cure cancer so t-cells is basically a subtype of

so t-cells is basically a subtype of

so t-cells is basically a subtype of your white blood cells what these people

your white blood cells what these people

your white blood cells what these people did was to harvest the T cells from a

did was to harvest the T cells from a

did was to harvest the T cells from a patient’s body reprogram it to make it

patient’s body reprogram it to make it

patient’s body reprogram it to make it targets specifically against tumor

targets specifically against tumor

targets specifically against tumor cancers and then put it back into a

cancers and then put it back into a

cancers and then put it back into a patient so this type of technology say

patient so this type of technology say

patient so this type of technology say just five years ago because as drug

just five years ago because as drug

just five years ago because as drug discovery is basically dominated by

discovery is basically dominated by

discovery is basically dominated by small molecules the small molecules are

small molecules the small molecules are

small molecules the small molecules are organic compounds typically less than

organic compounds typically less than

organic compounds typically less than $1,000 they are very very small

$1,000 they are very very small

$1,000 they are very very small molecules so in comparison for example

molecules so in comparison for example

molecules so in comparison for example one strain of your DNA basically a

one strain of your DNA basically a

one strain of your DNA basically a billion Delta so small molecules have

billion Delta so small molecules have

billion Delta so small molecules have served as well over the past few decades

served as well over the past few decades

served as well over the past few decades remember your paracetamol

remember your paracetamol

remember your paracetamol or your panadol or your aspirin these

or your panadol or your aspirin these

or your panadol or your aspirin these are all small molecules so small

are all small molecules so small

are all small molecules so small molecules are very popular because they

molecules are very popular because they

molecules are very popular because they are easy to manipulate as well as easy

are easy to manipulate as well as easy

are easy to manipulate as well as easy to produce but they have one drawback in

to produce but they have one drawback in

to produce but they have one drawback in the sense that the tip but they are not

the sense that the tip but they are not

the sense that the tip but they are not specific so what this means is that

specific so what this means is that

specific so what this means is that there’s always a remote chance of these

there’s always a remote chance of these

there’s always a remote chance of these small molecules acting as drugs

small molecules acting as drugs

small molecules acting as drugs interacting with unknown these

interacting with unknown these

interacting with unknown these at Target and this could spell problem

at Target and this could spell problem

at Target and this could spell problem later on in a position in terms of side

later on in a position in terms of side

later on in a position in terms of side effects so on the other hand logics are

effects so on the other hand logics are

effects so on the other hand logics are very specific and it acts only on one

very specific and it acts only on one

very specific and it acts only on one particular target and the fact that

particular target and the fact that

particular target and the fact that biologics is based on living organism it

biologics is based on living organism it

biologics is based on living organism it is perceived is perceived but it’s not

is perceived is perceived but it’s not

is perceived is perceived but it’s not always the case that it is safer with

always the case that it is safer with

always the case that it is safer with less side effects so have come a long

less side effects so have come a long

less side effects so have come a long way during the past few years in 2014

way during the past few years in 2014

way during the past few years in 2014 six of the top ten best-selling drugs

six of the top ten best-selling drugs

six of the top ten best-selling drugs are smaller molecules so the trend was

are smaller molecules so the trend was

are smaller molecules so the trend was reversed in 2015 and 2016 where the DOM

reversed in 2015 and 2016 where the DOM

reversed in 2015 and 2016 where the DOM blood drops down to only two with the

blood drops down to only two with the

blood drops down to only two with the rest dominated by biologists so we can

rest dominated by biologists so we can

rest dominated by biologists so we can actually see a changing trend over here

actually see a changing trend over here

actually see a changing trend over here in between the popularity of biologics

in between the popularity of biologics

in between the popularity of biologics and small molecules the de jure is

and small molecules the de jure is

and small molecules the de jure is sustainable it’s left to be seen but no

sustainable it’s left to be seen but no

sustainable it’s left to be seen but no matter whether we are talking about

matter whether we are talking about

matter whether we are talking about biologics or small molecules is still

biologics or small molecules is still

biologics or small molecules is still take five to six years in terms of drug

take five to six years in terms of drug

take five to six years in terms of drug discovery and if you include that with

discovery and if you include that with

discovery and if you include that with drug development and to bring a drug

drug development and to bring a drug

drug development and to bring a drug from the lab bench to clean it it will

from the lab bench to clean it it will

from the lab bench to clean it it will still take about 10 to 15 years and

still take about 10 to 15 years and

still take about 10 to 15 years and still very long time it’s not to mention

still very long time it’s not to mention

still very long time it’s not to mention the success rate extremely low success

the success rate extremely low success

the success rate extremely low success rate of just 0.05 percent on average

rate of just 0.05 percent on average

rate of just 0.05 percent on average coupled with hefty price tag of more

coupled with hefty price tag of more

coupled with hefty price tag of more than 2.6 billion u.s. dollar

than 2.6 billion u.s. dollar

than 2.6 billion u.s. dollar so now you know why sometime drugs are

so now you know why sometime drugs are

so now you know why sometime drugs are sorted right so one of the trend which

sorted right so one of the trend which

sorted right so one of the trend which scientists has been looking at is on

scientists has been looking at is on

scientists has been looking at is on heart of therapy the one of the ways

heart of therapy the one of the ways

heart of therapy the one of the ways that we could do it is repurpose or

that we could do it is repurpose or

that we could do it is repurpose or drugs what this means is that

nutrients so humans have been

nutrients so humans have been repurposing we have been changing into

repurposing we have been changing into

repurposing we have been changing into museums we have we have been changing

museums we have we have been changing

museums we have we have been changing all tires into swings and so on and so

all tires into swings and so on and so

all tires into swings and so on and so forth so why not drugs

forth so why not drugs

forth so why not drugs so repurposing in drug discovery refers

so repurposing in drug discovery refers

so repurposing in drug discovery refers to a situation when a poof drop finds

to a situation when a poof drop finds

to a situation when a poof drop finds another use which is to treat a

another use which is to treat a

another use which is to treat a different disease so James black a Nobel

different disease so James black a Nobel

different disease so James black a Nobel laureate in Maxim wants water that the

laureate in Maxim wants water that the

laureate in Maxim wants water that the best way to find a nutria is to start

best way to find a nutria is to start

best way to find a nutria is to start one a very wise man anybody knows vigor

one a very wise man anybody knows vigor

one a very wise man anybody knows vigor all right I can see some guys over there

all right I can see some guys over there

all right I can see some guys over there nodding the head smiling yeah so Hydra

nodding the head smiling yeah so Hydra

nodding the head smiling yeah so Hydra was originally developed to treat

was originally developed to treat

was originally developed to treat cardiovascular disease but along the way

cardiovascular disease but along the way

cardiovascular disease but along the way in this clear sense that makes a better

in this clear sense that makes a better

in this clear sense that makes a better treatment in treating erectile

treatment in treating erectile

treatment in treating erectile dysfunction and it’s popular for its

dysfunction and it’s popular for its

dysfunction and it’s popular for its later application as people tends to

later application as people tends to

later application as people tends to forget what’s originally developed for

forget what’s originally developed for

forget what’s originally developed for so this just shows one of the success

so this just shows one of the success

so this just shows one of the success successful ways of repurposing and audre

successful ways of repurposing and audre

successful ways of repurposing and audre so it makes complete sense to Reaper it

so it makes complete sense to Reaper it

so it makes complete sense to Reaper it will only take only called an encode 300

will only take only called an encode 300

will only take only called an encode 300 million u.s. dollar and six and half

million u.s. dollar and six and half

million u.s. dollar and six and half years to repurpose a lot compared to 2.6

years to repurpose a lot compared to 2.6

years to repurpose a lot compared to 2.6 billion u.s. dollars as mentioned just

billion u.s. dollars as mentioned just

billion u.s. dollars as mentioned just now or 10 to 15 years to develop a

now or 10 to 15 years to develop a

now or 10 to 15 years to develop a completely new one another area which

completely new one another area which

completely new one another area which has been receiving a lot of attention

has been receiving a lot of attention

has been receiving a lot of attention and heavy investment is artificial

and heavy investment is artificial

and heavy investment is artificial hodgins kind of like right now

multimillion-dollar tie-up between

multimillion-dollar tie-up between leading pharmaceutical companies and AI

leading pharmaceutical companies and AI

leading pharmaceutical companies and AI service providers has been announced air

service providers has been announced air

service providers has been announced air to be able to increase the chance of

to be able to increase the chance of

to be able to increase the chance of success in identifying user by helping

success in identifying user by helping

success in identifying user by helping to predict which molecule so how it will

to predict which molecule so how it will

to predict which molecule so how it will work how he will behave and become a

work how he will behave and become a

work how he will behave and become a useful drug so a is perceived to be able

useful drug so a is perceived to be able

useful drug so a is perceived to be able of the cost of approach by doing away

of the cost of approach by doing away

of the cost of approach by doing away with unnecessary tests yeah it’s not

with unnecessary tests yeah it’s not

with unnecessary tests yeah it’s not something very new in a sense that he

something very new in a sense that he

something very new in a sense that he has been around in the 1970s or the

has been around in the 1970s or the

has been around in the 1970s or the 1980s so what makes the difference

1980s so what makes the difference

1980s so what makes the difference between the AI in the past and the AI

between the AI in the past and the AI

between the AI in the past and the AI now so AI now is much more powerful

now so AI now is much more powerful

now so AI now is much more powerful compared to AI thirty to forty years ago

compared to AI thirty to forty years ago

compared to AI thirty to forty years ago what actually makes the difference is

what actually makes the difference is

what actually makes the difference is that they have developed a superior

that they have developed a superior

that they have developed a superior neural networking which means that AI

neural networking which means that AI

neural networking which means that AI now is able to learn to perform tasks

now is able to learn to perform tasks

now is able to learn to perform tasks faster and better without specific tasks

faster and better without specific tasks

faster and better without specific tasks programming we actually can sense a big
