Three novel quinonyl muramyldipeptides, 2-2-acetamido-2-deoxy-6-O-[10-(2, 3-dimethoxy-5-methyl-1, 4-benzoquinon-6-yl) decanoyl]-D-glucopyranos-3-O-yl}-D-propionyl-L-valyl-D-isoglutamine methyl ester (1a) and its Ser and Thr analogues (1b and 1c), were synthesized and their antitumor effects on the suppression of tumor growth in syngeneic mice were assayed. Among these compounds, 1a showed the most potent antitumor activity.
研究人员合成了三种新型醌基喃喃二肽--2-2-乙酰
氨基-2-脱氧-6-O-[10-(2, 3-二甲氧基-5-甲基-1, 4-苯醌-6-基)癸酰基]-
D-吡喃葡萄糖-3-O-基}-D-丙酰基-L-缬
氨酰基-D-异谷
氨酰胺甲酯(1a)及其 Ser 和 Thr 类似物(1b 和 1c)、合成了这些化合物,并检测了它们对抑制合成小鼠肿瘤生长的抗肿瘤作用。在这些化合物中,1a 的抗肿瘤活性最强。
