The synthesis of MDP (muramyl dipeptide) or nor-MDP (normuramyl dipeptide) conjugates modified at the peptide part with batracylin (BAT) or batracylin derivatives is described. Batracylin was synthesized by our modified method (Scheme 3). The synthesis of BAT via this modified route now appears to be feasible on a multigram scale. Preliminary screening data obtained at the National Cancer Institute
描述了在合成肽中修饰了巴蒂西林(BAT)或巴蒂西林衍生物的MDP(村木基二肽)或nor-MDP(诺木尔基二肽)缀合物的合成。Batracylin是通过我们的改良方法(方案3)合成的。现在,以这种改进的路线合成BAT在多克规模上似乎是可行的。在美国国家癌症研究所(NCI,贝塞斯达,马里兰州)获得的初步筛选数据显示,即使在10(-4)-10(-8)M或microg / mL下,结合物也没有暴露任何细胞毒活性。在波兰格但斯克医科大学进行的测试中,与单独的batracylin相比,两种类似物11c和11e在体外降低了Ab黑色素瘤细胞的增殖(表2,图1)。
