An environmentally benign synthesis of 3,3’-bis(indolyl)methanes (BIMs) has been developed from arylmethylamines and indoles under aerobic condition in presence of oxone. The formation of BIMs using ethanol as a green reaction medium represents a good practical method for synthesis. The good tolerance was observed towards various functional groups for exploring substrate scope in presence of oxone

and environment friendly method has been developed for the synthesis of bis(indolyl)methanes using chitosan in aqueous medium. The use of commercially available chitosan without any modifications eliminated the need of toxic metal catalysts and minimized the cost and waste generation. The optimized reaction conditions involved the use of water as solvent at reflux temperature for the model reaction between

An efficient protocol for synthesis of 3,3'-diindolylmethanes using recyclable Fe-pillared interlayered clay (Fe-PILC) catalyst under aqueous medium has been developed. All synthesized 3,3'-diindolylmethanes showed promising antileishmanial activity against Leishmania donovani promastigotes as well as axenic amastigotes. Structure-activity relationship analysis revealed that nitroaryl substituted diindolylmethanes showed potent antileishmanial activity. The 4-nitrophenyl linked 3,3'-diindolylmethane 8g was found to be the most potent antileishmanial analog showing IC50 values of 7.88 and 8.37 mu M against both L donovani promastigotes and amastigotes, respectively. Further, a pharmacophore based QSAR model was established to understand the crucial molecular features of 3,3'-diindolylmethanes essential for potent antileishmanial activity. These compounds also exhibited promising antifungal activity against Cryptococcus neoformans, wherein fluorophenyl substituted 3,3'-diindolylmethanes were found to be most potent antifungal agents. Developed synthetic protocol will be useful for economical and eco-friendly synthesis of potent antileishmanial and antifungal 3,3'-diindolylmethane class of compounds. (C) 2013 Elsevier Masson SAS.

evaluated for their anticanceractivity against various human cancer cell lines. Some of these compounds exhibited good inhibitory activity against most of the cell lines tested. Interestingly all the compounds from the bisindole sulfonate series exhibited selective inhibition against MCF-7 cell line. Further these compounds have also been tested for their inhibition of tubulinpolymerization. The compounds
