Anti-inflammatory constituents from the fruits of Vitex rotundifolia

Bioorg Med Chem Lett. 2013 Nov 1;23(21):6010-4. doi: 10.1016/j.bmcl.2013.08.004. Epub 2013 Aug 9.

Abstract

Three new diterpenes (7, 15 and 17) and two new neolignans (19 and 20) along with nineteen known compounds have been isolated from the fruits of Vitex rotundifolia. Their structures were elucidated by a combination of 1D and 2D NMR, HRESI-MS, and CD data. All isolates were tested for their inhibitory activities on LPS-induced nitric oxide production in RAW264.7 cells. Of these, compounds 3, 4, 7, 13, 15, 19, and 24 found to inhibit nitric oxide production with the IC50 values ranging from 11.3 to 24.5μM.

Keywords: Diterpene; Neolignan; Nitric oxide; Verbenaceae; Vitex rotundifolia.
