Abstract

The oligomeric stilbenes (+)-α-viniferin (1), miyabenol C (2), and kobophenol A (3) have been isolated from Caragana sinica (Buchoz) Rehd (Leguminosae). (+)-α-Viniferin (1) and miyabenol C (2) exhibited protein kinase C inhibitory activity at low micro-molar concentrations. (+)-α-Viniferin inhibited kera-tinocyte proliferation (0.4 µM) and free radical release in whole blood (47 µM), in vitro, and may be useful in treating hyperproliferative or inflammatory skin diseases.

Key words

Caragana sinica (Buchoz) Rehd - Leguminosae - (+)-α-viniferin - miyabenol C - kobophenol A - oligomeric stilbenes - protein kinase C activity
