Do I develop one Molecule

at a time?

Questions in my mind:

Do I develop all the Drugs at one shot? Platform

Technology?What area

do I apply this Technology?

Guerrilla Tactic – 1 : Narrow area of attack with maximum impact

• What is Aspirin?• Chemically it is Acetyl Salicylic Acid

CLASSICAL AGE OLD DRUG

Guerrilla Tactic – 2 : Solution is sometimes right before the eyes

Guerrilla Tactic – 3 : New association among unrelated concepts

A drug/chemical that thins blood is an effective cardio-protective agent.

Can we therefore develop a new anti-platelet drug that is effective, but has minimal or

no side effects?

Important Conclusion Question

Guerrilla Tactic – 4 : Specificity of Approach to New Drug Development

We will attach a suitable chemical

group to the existing drug to

eliminate its toxicity and improve

Therapeutic Index.

Guerrilla Tactic – 6 : Versatile

Which Amino Acids?

L - Threonine

L - Tyrosine

L – Hydroxy Proline

L – Serine

Surprising Results in Animal Models

All 3 Amino Acid Esters are equal

effective

L – Threonine ester is better than other two

and AspirinNone of the 3 Amino Acids

Esters showed any toxicity in rat

models

Guerrilla Tactic – 7 : Creativity turns Problems into Opportunities

How to rapidly advance a NCE without an IND from Lab to Clinical Trials

Guerrilla Tactic – 8 : Simple Techniques are sometimes most useful

What can be an effective, simple and reliable technique to measure effectiveness

of anti-platelet drugs in humans

Human Clinical Trials

Percentage increase in clotting time PLATROL vs.. Aspirin (Bayer) at 81mg dose based on 5-day average increase. The two PLATROL blocks shown above correspond to two separate volunteers who took the test drug over a period of 5 days. The third volunteer took Bayer Aspirin for 5 days. As per Figure 2, increase in clotting time for PLATROL occurred on the very first day of drug intake, and remained higher than Bayer ASA during the subsequent administrations.

CONCLUSIONS

Acetyl group is responsible for Anti-Platelet

Activity of Aspirin

L-Threonine ester of Aspirin is a good carrier of

Acetyl Group

Salicylic Acid is also a good carrier of

Acetyl group

Are we finally getting closer to finding a “super”

Aspirin?

Are there better carriers of

Acetyl Group than Salicylic

Acid?

Let us go back and take one more look at Aspirin and Salicylic Acid.

Guerrilla Tactic – 9 : Capitalize on what others totally missed

Is there a naturally occurring molecule (that is essential to

the human body) comes very close to our requirements

Guerrilla Tactic – 10 : Nature has the Answer

Yes!

Acetylate L-Tyrosine and

test it for anti-platelet activity.

Make acetyl ester of all other naturally

occurring OH containing Amino

Acids.

Dramatic results with Acetylated Amino Acids!

Both at 81 and 325 mg dose, Bayer

Aspirin increased clotting time only

by 13%

O Acetyl Tyrosine increased

clotting time by more than 50%

and it was sustained after

24 hrs

O Acetyl Serine increased

clotting time by 23%

Advantages of Acetylated Amino Acids1. Non-toxic2. All metabolites are natural to human body3. All 4 AA are good carriers of acetyl group4. Mechanism of action is identical to Aspirin5. No Toxicity whatsoever6. All AAA are nutritional supplements7. Require no FDA approval to test 8. No NDA needed for marketing 9. Ideally suited for long term therapy

Guerrilla Tactic – 11 : Synergy

Now, how about Acetylated Dipeptides

Will they have any Anti –

platelet activity?

1. Rapid increase in clotting time (up to 87.5%)2. Sustained increase in clotting time (37.5%) up to 8 days!3. Is it as good as dissolving clot like TPA? Or it can replace

Aspirin in sudden heart attack? Likely so.4. Non Toxic5. No Side effects or adverse reactions6. Qualifies as nutritional supplement, hence requires no IND

or NDA to test in human subjects7. Qualifies for matter of composition patent, as it is novel, and

patentable.
