•IIIM
discovered that Piperine (an alkaloid from an Indian plant) as a
potent inhibitor of CYP-450/P-gp and shown to enhance
bioavailability of rifampicin.
•PK studies showed that a rifam
picin (450 Standard) was bioequivalent
to a low dose of drug (200 m
g) in presence of piperine (10 m
g) due to
inhibition of Rif m
etabolizing enzymes by piperine, compensating
enzyme induction by Rif.
•After successful preclinical development and clinical trials, the drug
has been approved in the DCGI for marketing (Cadila Pharma, India)

Effect on aortic ring: Acetylcholine (ACh) in a dose dependent manner produced endothelium dependent
relaxation in phenylephrine (1 ×10-6 M) precontracted isolated rat aortic ring preparation. At 300 micromole, ACh
showed maximum relaxation of 80.9 ±4.88 % (p<0.001). K002 followed the same pattern and exhibited
maximum relaxation of 54.5 ±7.84 % with equal concentration. The vasoreactivity of K002 was reduced to 10-
15% in the denuded aortic ring, indicating K002 effects are mediated via the receptor located on the endothelium

Safety studies
♦Single dose acute toxicity: 5 g/kg (p.o.) in rats ─ No Mortality
♦One week toxicity: 1 g/kg/day(p.o.) (two divided doses) for 1 week–No Mortality
Conclusions:
♦Strong inhibitor of gastric H+Pump. Inhibition is perhaps irreversible in nature.
♦Inhibits basal acid secretion (40%) and histamine-stimulated acid secretion (25%) at 50 µg/ml
in isolated gastric parietal cells. It isSpecific against H
. pylo
ri.
♦It is more like bacteriostatic (time kill assay; MBC ~ 200 µg/ml with majority of the strains).

Immunosuppressive candidate
Plant: RJM1195 (Stem/leaf). Bioactivity in Alcoholic (A001) and Modified
Alcoholic Extract (RE-4)
Extract A001 potent but Toxic.
The extract RE4 devoid of toxicityis potent TNF alpha inhibitor, anti-arthritic
activity (using CIA model in mice, Nicolas Piramal). Anti-arthritic activity
using Mycobacterium Adjuvant Induced Arthritis in rats.
Anti-inflammatory activity using Carrageenan induced edema in rats.
Confidential
Anti-inflammatory activity using Carrageenan induced edema in rats.
Six compounds isolated from RE4, (triterpenoid / steroids) are less active
than RE4. Therefore, RE4 pursued).
Conclusion:
Bioactive extract RE-4has significant TNFαinhibitory, anti-arthritic and anti-
inflammatory activities.
TNFαinhibitors are in demand for the treatment of Rheumatoid Arthritis at
present and thus the lead is important.
