摘要

Sanguinarine (1) and chelerythrine (2) are two quaternary benzo [c] phenanthridine alkaloids (QBAs). Eighteen derivatives of 1 and 2 were synthesized by modification of C= N+ bond and evaluated for their in vitro acaricidal activity against Psoroptes cuniculi, a mange mite. A new method was developed to prepare 6-alkoxy dihydro derivatives of 1 and 2 (1a– e, 2a–e). Among all the compounds, only 6-alkoxy dihydrosanguinarines (1a–e) showed ...
