The preparation of pharmaceutically active 2-amino-4H-chromene derivatives has been achieved using a nano powder of natural clinoptilolite (CP) zeolite. A wide range of these worthy structures having diverse substituents on the 4H-chromene ring were efficiently synthesized via the reaction of an aromatic aldehyde and variety of enolizable C–H activated acidic compounds. Nano sized natural clinoptilolite

Pyrano[3,2-c]pyridone and pyrano[3,2-c]quinolone structural motifs are commonly found in alkaloids manifesting diverse biological activities. As part of a program aimed at structural simplification of bioactive natural products utilizing multicomponent synthetic processes, we developed compound libraries based on these privileged heterocyclic scaffolds. The selected library members display low nanomolar antiproliferative activity and induce apoptosis in human cancer cell lines. Mechanistic studies reveal that these compounds induce cell cycle arrest in the G2/M phase and block in vitro tubulin polymerization. Because of the successful clinical use of microtubule-targeting agents, these heterocyclic libraries are expected to provide promising new leads in anticancer drug design.

2-c]quinoline based structural analogues was synthesized using one-pot multicomponent condensation between 2,4-dihydroxy-1-methylquinoline, malononitrile, and diverse un(substituted) aromatic aldehydes. The synthesized compounds were evaluated for their anti-inflammatory and cytotoxicity activity. Initially, all the compounds were evaluated for the percent inhibition of cytokinerelease, and cytotoxicity activity
