Based on crystallographic data of the complexes 2-alkyl(amino)ethyl-1,1-bisphosphonates–Trypanosoma cruzi farnesyl diphosphate synthase, some linear 1,1-bisphosphonic acids and other closely related derivatives were designed, synthesized and biologically evaluated against T. cruzi, the responsible agent of Chagas disease and against Toxoplasma gondii, the etiologic agent of toxoplasmosis and also towards the target enzymes farnesyl pyrophosphate synthase of T. cruzi (TcFPPS) and T gondii (TgFPPS), respectively. The isoprenoid-containing 1,1-bisphosphonates exhibited modest antiparasitic activity, whereas the linear α-fluoro-2-alkyl(amino)ethyl-1,1-bisphosphonates were unexpectedly devoid of antiparasitic activity. In spite of not presenting efficient antiparasitic activity, these data turned out to be very important to establish a structural activity relationship.
基于2-烷基(氨基)乙基-1,1-双膦酸酯与克鲁兹锥虫法尼基二磷酸合成酶的晶体学数据,设计、合成了一些线性1,1-双膦酸及其他密切相关的衍生物,并对其在针对克鲁兹锥虫(造成查加斯病的病原体)和弓形虫(造成弓形虫病的病原体)的生物活性进行了评估,同时也针对克鲁兹锥虫(TcFPPS)和弓形虫(TgFPPS)的目标酶法尼基焦磷酸合成酶进行评估。含异戊烯基的1,1-双膦酸酯表现出适度的抗寄生虫活性,而线性α-氟-2-烷基(氨基)乙基-1,1-双膦酸酯则出人意料地缺乏抗寄生虫活性。尽管未表现出有效的抗寄生虫活性,这些数据对于建立结构活性关系却显得非常重要。
