Chemical manipulation studies were conducted on betulinic acid (), twenty-one new rationally designed analogues of 1 with modifications at C-28 were synthesized for their evaluation of inhibitory effects on α-glucosidase and LPS-stimulated nitric oxide production in mouse macrophage RAW 264.7 cells. Compound (IC = 5.4 μM) exhibited an almost 1.4-fold increase in α-glucosidase inhibitory activity on yeast α-glucosidase while analogues (IC 16.4 μM) and (IC 16.6 μM) exhibited a 2-fold enhanced inhibitory activity on NO-production than betulinic acid.
进行了白桦脂酸()的化学操作研究,合成了 21 种新型的 1 位 C-28 位结构修饰的理性设计类似物,以评估其对α-葡萄糖苷酶的抑制作用和 LPS 刺激的 RAW 264.7 细胞中一氧化氮生成的抑制作用。化合物(IC = 5.4 μM)对酵母α-葡萄糖苷酶的α-葡萄糖苷酶抑制活性增加了近 1.4 倍,而类似物(IC 16.4 μM)和(IC 16.6 μM)对 NO 生成的抑制活性比白桦脂酸增加了 2 倍。
