Diindolylmethane (DIM) is a metabolic product of indole-3-carbinol (I3C), the major phytochemicals present in cruciferous vegetables, which can modulate multiple signalling pathways in cancer. The present study deals with the mechanism of action of two synthetic biaryl conjugates of DIM in triple negative breast cancer cells. Out of 12 DIM derivatives tested, two compounds, DIM-1 and DIM-4, exhibit cytotoxicity with GI values of 9.
View Article and Find Full Text PDFLectins are a unique class of carbohydrate binding proteins/glycoproteins, and many of them possess anticancer properties. They can induce cell cycle arrest and apoptosis, inhibit protein synthesis, telomerase activity and angiogenesis in cancer cells. In the present study, we have demonstrated the effect of leaf lectin (MLL) on anoikis induction in MCF-7 cells.
View Article and Find Full Text PDFA bioactive compound was purified from the culture medium of a new strain of BSN307 by solvent extraction followed by chromatographic techniques. This bioactive compound was identified to belong to phenazine class of compounds by MS, NMR and FTIR. The phenazine compound showed antifungal activity against , as well as by disc diffusion assay in addition to antioxidant potential as demonstrated by DPPH scavenging assay.

Compounds 1-12 were synthesized, with variations in one of the phenyl unit, in a single step by condensation of biaryl-2-carbaldehydes with indole in the presence of para-toluenesulfonic acid. Compound 1 exhibited a GI50 value of 11.

In addition, the structures of the ligand () and complex were established unambiguously through X-ray crystal structure analysis. Uniquely, the coordination with a metal ion modified the ligand scaffold to interact efficiently with ct-DNA (groove binding) as well as protein (hydrophobic and/or electrostatic interactions).
