3. Derived from Greek words
oPharmakon - Drug
oLogos - Study
A drug is a moiety substance or chemical
entity which when consumed can intervene
at physical, physiological and
psychological levels.

WHAT IS PHARMACOLOGY ?
5. • Reverse pharmacology is defined as science of
integrating documented experiments hits into leads that
are further developed into drug candidate or formulations
through more systematic and precisely designed
preclinical and clinical research.
• Salient feature of this approach is the combination of
knowledge learned from traditional or folk medicine and
the modern technology to provide better and safe leads.
REVERSE PHARMACOLOGY AND ITS APPROACH
5
6. A representative of a compound series with sufficient
potential to progress to a full drug development
program
Lead is derived from hit, and has the desired activity
which is confirmed upon retesting.
KEY WORDS:
A drug target is a molecule in the body, associated with a particular
disease process and that could be addressed by a drug to produce a
desired therapeutic effect.

10. HISTORY OF REVERSE
PHARMACOLOGY IN INDIA
• Sir Gananath Sen
Father of Reverse pharmacology
Laid the foundation of Reverse
pharmacology of medicinal plants
In 1993
demonstrated the
antihypertensive
and tranquilizing
effect of Rawolfia
serpentina.
Also observed
unique side effect
such as depression,
extra pyramidal
syndrome and
peptic ulcers

11. DOMAINS OF REVERSE PHARMACOLOGY
11
Experimental Hits
and Targets
Exploratory
leads
13. RESPONSE MOLECULE
• A mechanism of action usually
includes mention of the specific
molecular targets to which the
drug binds, such as an enzyme
or receptor.
13
• Receptor sites have specific
affinities for drugs based on
the chemical structure of the
drug, as well as the specific
action that occurs there.
19. Despite a vast potential and possibilities- very few success stories
Most of the work in the field has remained in clinics of
traditional practitioners or confined to academic research
laboratories
Improper experimental documentation
Lack of proper identity and implementation of
good laboratory practices
Cultural prejudice for
Alien Science.

The drug candidate is

24. Three main bottlenecks in drug development (Time, Money and Toxicity)
can easily addressed by reverse pharmacology.
It potentiates fast track drug development of newer, safer, and effective
drugs.
Normal drug developmental course “Laboratory to clinic” actually
becomes “Clinics to Laboratory” in RP.
These records are particularly valuable since effectively these medicines
have been tested for thousands years on people.
CONCLUSION
24
26. • Many countries are becoming extremely aware of their traditional knowledge.
• Global pharmaceuticals industry is looking for innovative solutions to re-activate and re-
energize discovery pipeline.
• Adds a new life in existing global economic environment.
• It will be the interest of pharmaceutical companies, researchers and ultimately the global
community to respect the tradition build on their knowledge and experiential wisdom
