Design, synthesis of novel N prenylated indole-3-carbazones and evaluation of in vitro cytotoxicity and 5-LOX inhibition activities

Abstract

A series of novel N-1 and C-3 substituted indole derivatives (5a–f) were designed, synthesized and evaluated for their cytotoxic properties, viz Brine Shrimp Lethality Bioassay (BSLB) besides 5-Lipoxygenase (5-LOX) inhibitory activities through in vitro assays. Structure Activity Relation (SAR) studies showed that compound 5d with an LC50 of 6.49 μM and 5c with an IC50 of 33.69 μM were found to be interesting for cytotoxicity and 5-LOX inhibitory activity respectively.
