New esters (sulfate, nicotinates, and 4-methoxycinnamate) of 18α-glycyrrhizic acid (18α-GA) were synthesized; these were D/E--isomers of natural 18β-GA (GA), which is the major triterpene glycoside in the roots of Spanish licorice and Urals licorice ( L. and Fisher). Changes in the stereochemistry of the GA aglycone led to significant decreases in its anti-HIV-1 activity.
合成了18α-甘草酸(18α-GA)的新酯(硫酸盐、烟酸盐和4-甲氧基肉桂酸酯);这些是天然18β-甘草酸(GA)的D/E-异构体,GA是西班牙甘草和乌拉尔甘草(L.和Fisher)根中的主要三萜糖苷。GA苷元立体化学的变化导致其抗HIV-1活性显著降低。
