Summary
16 triphenylacrylonitriles (TPE) or diphenylacrylonitïiles (DPE) were synthesized by condensation of various. benzophenones or benzaldehydes with various phenylacetonitriles. The pharmacological potency of these compounds was studied by incubation of bovine seminal vesicle microsomes and PG-RIA. The results showed that the potency of inhibition of PG biosynthetase of DPE was stronger than that of TPE. Compounds with electron-releasing functional groups were proved to be more effective than those with electron-attracting groups. Compound DPE-9 was the most active one, the potency of which was 40 times stronger than that of naproxen. The structure of some compounds has been analysed by X-ray diffraction. The relationship between structure and activity was investigated by means of X-ray diffraction, UV and NMR.
