Structure-activity relationship of in vitro antiviral and cytotoxic activity of semisynthetic analogues of scopadulane diterpenes.

Fourteen semisynthetic compounds derived from the natural scopadulane-type diterpenes thyrsiflorin A (4), B (5), and C (6), including several precursors, have been examined in vitro for their antiherpetic activity against Herpes simplex virus type II (HSV-2) and cytotoxicity against two human tumor cell lines. Four of these compounds showed moderate antiherpetic activity, but none of them exhib...

New rearranged clerodane diterpenes from Tinospora baenzigeri.

Baenzigeroside B, a new rearranged clerodane diterpene glucoside, was isolated from the stems of Tinospora baenzigeri. The aglycone of baenzigeroside B, baenzigeride B (isolated as its acetate), was found together with baenzigeride A, baenzigerosides A and B in the leaves of the same plant. Baenzigeride B and baenzigeroside B are the first examples of a new class of rearranged clerodane diterpe...
