Synthesis and Antitumor Activity of 20(S)-Camptothecin Derivatives: Carbamate-Linked, Water-Soluble Derivatives of 7-Ethyl-10-hydroxycamptothecin.
Nevel 36 derivatives (6), bonding the phenolic hydroxyl group of 7-ethyl-10-hydroxycamptothecin (4) with diamines through a monocarbamate linkage, were synthesized and their antitumor activity was evaluated in vivo. The derivatives were soluble in water as their HC1 salts wiht the E lactone ring intact and exhibited significant antitumor activity. One of the derivatives, 6-27 showed excellent activity against L1210 leukemia and other murine tumors.The structure of its hydrochloride trihydrate (CPT-11) was determined by spectroscopic and crystallographic methods.
A series of novel 9-O-substituted-berberine derivatives were synthesized and their anti-inflammatory activities were evaluated. Among them, compounds 3i and 5e exhibited excellent anti-inflammatory potential.
