coupling of the amino terminus of d-phenylalanine methyl ester to the free 5′-carboxylic acid moiety of 33 followed by sodium hydroxide treatment led to carboxylic acid analog 77. Hydrolysis of this material gave analog 78. The intermediate 77 served as the precursor for the preparation of novel dipeptidyl uridine analogs 79–99 through peptide coupling reactions to diverse amine reactants. None of the described
在 NIH 路线图计划的中试规模库 (PSL) 计划下,以溶液相方式从胺2和羧酸33和77合成了一个包含 94 种尿苷抗生素类似物的小型库。多样醛,磺酰氯,和羧酸反应物套缩合,2,酸介导的水解导致后,向目标化合物3 - 32以良好的收率和高的纯度。同样,用不同的胺和磺胺处理33得到34 – 75。d氨基末端的偶联-苯丙氨酸甲酯到33的游离 5'-羧酸部分,然后用氢氧化钠处理产生羧酸类似物77。该材料的水解得到类似物78。中间77担任该前体为二肽基新颖尿苷类似物的制备79 - 99通过肽偶联到不同的胺反应剂反应。所描述的化合物均未显示出显着的抗癌或抗疟活性。通过 NIH MLPCN 计划提供和报告的初级筛选中的酶和受体,许多样品表现出各种有希望的抑制性、激动剂、拮抗剂或激活剂特性。
