BACKGROUND Plant-derived flavonoids, which occur abundantly in our daily dietary intake, possess antitumor, antibacterial, and free radical scavenging properties. They form active constituents of a number of herbal and traditional medicines. Several flavonoids have been shown to exert their action by interacting with DNA topoisomerases and promoting… (More)
Various 3,3′-diindolylmethane (DIM) derivatives were synthesized and the antibacterial activity of these compounds were tested against ten bacterial strains and their minimum inhibitory concentration (MIC) values were determined. The MIC values of derivatives 3a–d and 5a–e were ranging from 125 to 500 μg/mL. Among these derivatives,… (More)
A simple synthesis and in vitro antileishmanial activity of 29,30-dibromo-28-oxoallobetulin against the parasitic protozoans, Leishmania donovani and Leishmania major is described. The structure of the compound is established on the basis of spectral data (IR, NMR, MS). Both the antiproliferative effect and the cell cycle progression were studied.
