of PGE2, 16,16-dimethyl-PGE2, and PGF2 alpha analogues modified at the carboxyl terminus with tetrazole, amide, acylurea, imide, and sulfonimide functionalities was evaluated for uterine stimulant, bronchodilator, hypotensive, gastric antisecretory, and diarrheal activity. These compounds were prepared by modification of the Corey prostaglandin synthesis utilizing as a key step condensation of known
评估了在羧基末端用四唑,酰胺,酰脲,酰亚胺和磺酰亚胺官能团修饰的一系列PGE2、16,16-二甲基-PGE2和PGF2α类似物的子宫刺激性,支气管扩张剂,降压,胃抗分泌和腹泻活性。这些化合物是通过将已知的半缩醛与衍生自必需的取代phospho盐的叶立德缩合为关键步骤,通过修饰Corey前列腺素合成制备的。结构与活性之间的关系表明,C-1位置的质子似乎是激动剂活性所必需的,并且该质子的酸度对活性的影响比悬垂的空间体积更大。
