16 (S)-Methyl-20-methoxy-PGE2 (YPG-209) (Is), 16 (R)-methyl-20-methoxy-PGE2 (IR) and several analogs, such as 16 (S)-methyl-20-methoxy-PGA2 (XIIIs) and -PGB2 (XIVs), 16-methyl-20-ethoxy-PGE2 (XXVIIa), 16-methyl-20-hydroxymethyl-PGE2 (XXVIa), 16-methyl-17-oxa-ω-dihomo-PGE2 (XXVIIIa) and 20-hydroxymethyl-PGE2 (XXX), were synthesized by Corey's procedure and their biological activities were investigated. Among these derivatives, IS and IR possessed potent oral bronchodilator activity ; the bronchoselectivity of IS was higher than that of IR.
16 (S)-甲基-20-甲氧基-PGE2 (YPG-209) (Is)、16 (R)-甲基-20-甲氧基-PGE2 (IR) 和几种类似物,例如 16 (S)-甲基-20 -甲氧基-PGA2(XIIIs)和-PGB2(XIVs)、16-甲基-20-乙氧基-PGE2(XXVIIa)、16-甲基-20-羟甲基-PGE2(XXVIa)、16-甲基-17-氧杂-ω-通过Corey的方法合成了二同-PGE 2 (XXVIIIa)和20-羟甲基-PGE 2 (XXX)并研究了它们的生物活性。在这些衍生物中,IS 和 IR 具有有效的口服支气管扩张活性; IS的支气管选择性高于IR。
