Diester deoxyaconitine is very toxic.When deoxyaconitine was transformed into mono-ester aconitum alkaloids and lipo-alkaloids by human intestinal bacteria, the toxicity decreased.
双酯型的去氧乌头碱的毒性较高,当它被肠内细菌转化为单酯型和脂类物碱时会使其毒性
低。
Methods: Diester,diimide and dipeptide mimic compounds were synthesized by conjugated the amino groups and acid groups with diols or diacids links.
方法:通过酯化、酰胺由不同的二醇或二酸连接加巴喷丁和普瑞巴林合成二酯、酰胺、拟肽类等化合物。
