Acyclic nucleoside phosphonates (ANPs) are a promising class of antimalarial therapeutic drug leads that exhibit a wide variety of Ki values for Plasmodium falciparum (Pf) and human hypoxanthine-guanine-(xanthine) phosphoribosyltransferases [HG(X)PRTs]. A novel series of ANPs, analogues of previously reported 2-(phosphonoethoxy)ethyl (PEE) and (R,S)-3-hydroxy-2-(phosphonomethoxy)propyl (HPMP) derivatives
无环核苷膦酸酯(ANP)是一类很有前景的抗疟疾治疗药物,对恶性疟原虫(Pf)和人次黄嘌呤-鸟嘌呤-(黄嘌呤)磷酸核糖基转移酶[HG(X)PRTs)表现出多种Ki值。设计并合成了一系列新的ANP,它们是先前报道的2-(膦酰基乙氧基)乙基(PEE)和(R,S)-3-羟基-2-(膦酰基甲氧基)丙基(HPMP)衍生物的类似物,以评估它们的能力。充当这些酶的抑制剂,并扩展我们正在进行的抗疟疾结构活性关系研究。在这个系列中,(S)-3-羟基-2-(膦酰基乙氧基)丙基(HPEP),(S)-2-(膦酰基甲氧基)丙酸(CPME)或(S)-2-(膦酰基乙氧基)丙酸( CPEE)是无环部分。在这个群体中 (S)-3-羟基-2-(膦酰基乙氧基)丙基鸟嘌呤(HPEPG)对PfHGXPRT表现出最高的效力,Ki值为0.1μM,人HGPRT的Ki值为0.6μM。获得了与人HGPRT复合的HPEPG和HPEPHx(其中Hx
