Anti-HIV Tigliane-Type Diterpenoids from the Aerial Parts of Wikstroemia lichiangensis.

ABSTRACT: Tigliane-type diterpenoids have attracted much attention in drug discovery since they have been reported to exhibit remarkable biological effects, such as tumor-promoting, antineoplastic, and anti-HIV activities. In continuing our efforts to discover novel biologically important diterpenoids from Wikstroemia species, Wikstroemia lichiangensis was investigated phytochemically for the first time. As a result, four new (1-4) and one known (5) tigliane-type diterpenoid were isolated, and their structures were elucidated by spectroscopic data analysis. Tiglianes (1-5) showed potent anti-HIV activity against HIV-1 infection of MT4 lymphocytes with IC₅₀ values of 1.1-65.4 nM.
