Virtual screening for potential COX-inhibiting constituents from Mimosa pudica.

Developing a new agent in the anti-inflammatory and analgesic field, plants secondary metabolites can be a good source for the Non-Steroidal Anti-inflammatory Drugs (NSAID) drug development. For this purpose we subjected the active compounds of Mimosa pudica Linn. to reveal its potentiality by molecular docking analysis to find out its potent compound against COX which was done by GOLD docking analysis. Docking studies by GOLD showed that vitexin of Mimosa pudica had the highest fitness score against the COX-1 which is 60.43 and 63.49 for COX-2 enzyme. Vitexin of Mimosa pudica detected with significant fitness score and hydrogen bonding against COX-1 and COX-2 which may be a potent analgesic compound.

Evolution of selective COX-2 inhibitor from Alangium salvifolium: an in silico approach.

Pain and inflammation are linked with a number of pathological conditions. Several studies are in progress worldwide to find natural healing agents with better safety profile. Our current study was aimed to evaluate Alangium salvifolium (family: Alangeaceae) derived analgesic compounds for therapeutic drug discovery by computational approach. Literature based studies were used to explore the compounds of A. salvifolium. Ligands were prepared by following the appropriate procedures and finally in silico molecular docking analysis performed by GOLD 4.2. After post docking analysis, salviifosides A of Alangium salvifolium was found to have interaction on COX-2 protein by obtaining highest fitness score 50.64 and molecular interaction suggests that it could be a potent anti-inflammatory compound and it may be worth for further clinical trials.

In vitro Antioxidant Potential of Momordica charantia Fruit Extracts.

This research investigated the antioxidant potential of Momordica charantia fruit extracts in ethanol and ethyl acetate. The extracts have been assessed for DPPH free radical scavenging effect, FeCl3 reducing power and superoxide scavenging effect. In DPPH method IC50 value of ascorbic acid, ethanol and ethyl acetate extract were found 2.19 μg/ml, 111.87 μg/ml and 157.03 μg/ml respectively. In power reducing method, IC50 value of ascorbic acid ethanol and ethyl acetate extract were found 50 μg/ml, 931.63 μg/ml and 754.86 μg/ml respectively. In super oxide scavenging method, IC50 value of curcumin , ethyl acetate and ethanol extract were found 29.51 μg/ml, 331.26 μg/ml and 489.77 μg/ml respectively. The results of all three in vitro antioxidant assays exhibited that M. charantia possess relatively moderate antioxidant property than standards. The data obtained in the in vitro models clearly establish the antioxidant potency of the fruits extracts.
