Synthesis and antiradical and antioxidant activity of cycvalon and its analogs

A new approach to the activation of components of the condensation of aromatic aldehydes with cyclohexanone, functioning as a receptor for the CH-acid component, is demonstrated. The condensation was performed in the presence of excess phosphorus oxychloride with heating and formed the corresponding 2,6-dibenzylidenecyclohexanone derivatives at high yield. The antiradical and antioxidant activities of the resulting compounds were assessed and cycvalon was found to have the greatest activity. The reference compound (dibunol) did not quench free radicals and had less antioxidant activity than cycvalon. __________ Translated from Khimiko-Farmatsevticheskii Zhurnal, Vol. 41, No. 8, pp. 7–10, August, 2007.
