Study on the Synthesis and Biological Activity of Diacid Solanesyl Galactosyl Diesters Wang Chaojie, Wang Yuxia, Song Jinyong, Zhao Jin (Henan Provincial Key Laboratory of Special Functional Materials, Henan University, Kaifeng 475001) Abstract Six compounds of diacid solanesyl galactosyl diesters 4a～4f were first designed and synthesized by the reaction of O-acetylpyranosyl bromide with diacid solanesyl monoesters in the presence of tetrabutyl ammonium bromide. The structures of all the target compounds were characterized by IR, 1H NMR, MS and elemental analysis. Compound 4d was tested preliminarily for biological evalution on KB、Bel-7402、HCT-8、5-HT、TcAChE inhibitor models. The results show that this kind of compounds have only weak inhibitions on Bel-7402、HCT-8、5-HT、TcAChE inhibitor biomodels and no effect on KB cell.
