Abstract
Extensive phytochemical investigations on 30 Piper species growing in India and other medicinal plants have revealed the presence of a large number of novel compounds belonging to different classes. The antiviral activity of several lignans and neolignans belonging to different structural types has been evaluated against six different viral strains. Further, the effects of ethanol, chloroform, and hexane extracts of Piper longum and Piper galiatum on TNF-α induced expression of intercellular adhesion molecule-1 (ICAM-1) on human umbilical vein endothelial cells have been studied, a novel aromatic ester was isolated from the most active extract of P. longum. A potential antifungal compound having implications in treating aspergillosis was isolated from an important Indian medicinal plant, Datura metel.
