Preparation and in vitro evaluation of radioiodinated bakuchiol as an anti tumor agent.

Bakuchiol, extracted from the plant Psoralea corylifolia, has been proven to have anti-tumor, cytotoxic, anti-microbial and anti-inflammatory activity. In order to study if radiolabeled bakuchiol exhibits enhanced cytotoxicity, bakuchiol was radiolabeled with 125I. In-vitro uptake studies of 125I-bakuchiol were carried out using LS-A (lymphosarcoma) and barcl-95 (radiation-induced thymic lymphoma) ascitic and solid tumor cells of murine origin. In both LS-A and barcl-95, 125I-bakuchiol showed significant uptake. Viability studies showed that the radioiodinated compound showed greater cytotoxic effect than bakuchiol.
