Description

肽脱甲酰基酶抑制剂
发明领域
本发明涉及新颖的抗菌化合物的用途,以及含有作为肽脱甲酰基酶抑制剂的这些化合物的药物组合物。
发明背景
细菌引发物甲硫氨酰tRNA可以被甲硫氨酰tRNA转甲酰基酶(FMT)修饰,产生甲酰基-甲硫氨酰tRNA。然后将甲酰基甲硫氨酸(f-met)结合到新合成的多肽的N-末端。然后,多肽脱甲酰基酶(PDF或Def)将初级转移产物脱甲酰基化,生成N-甲硫氨酰基多肽。大多数的细胞内蛋白质被甲硫氨酸氨基肽酶(MAP)进一步处理,产生成熟的肽和游离的甲硫氨酸,所述游离的甲硫氨酸是可循环的。PDF和MAP都是细菌生长必需的,而PDF是MAP活性所需的。该反应系列称为甲硫氨酸循环(图1)。
               图1.甲硫氨酸循环
迄今为止,在细菌中、在含叶绿体的植物中、在小鼠和人体中已发现多肽脱甲酰基酶的同源基因。植物蛋白是核编码,但显示携带有叶绿体定位信号。这与观察到的叶绿体RNA和蛋白质合成过程与真细菌的合成过程高度相似是一致的。迄今为止,尚没有任何信息证明哺乳动物PDF基因同系物的蛋白质表达或这种蛋白质的功能性作用(Meinnel T.2000,ParasitologyToday,16(4),165-168)。
在所有真细菌中都发现了多肽脱甲酰基酶,而且其对于高覆盖基因组序列信息是有效的。PDF同系物中的序列差异很大,在较远的相关序列中仅仅20%一致。但是,活性位点周围的保留很高,有几个完全保留的残基,包括配位活性位点金属所需的一个半胱苷酸和两个组氨酸(Meinnel,T.等,1997,Journal of Molecular Biology,267,749-761)。
PDF被认为是有吸引力的抗细菌靶,因为已经证明这种酶是细菌体外生长所必需的(Mazel,D.等,EMBO J.13(4),914-923,1994),但不参与真核细胞的蛋白质合成(Rajagopalan等,J.Am.Chem.Soc.119,12418-12419,1997),并且在原核生物中普遍存在(Kozak,M.Microbiol.Rev.47,1-45,1983)。所以,PDF抑制剂可能作为广谱抗菌剂。
发明概述
本发明涉及下式(I)所示的新颖抗菌化合物,及其作为PDF抑制剂的用途。
本发明进一步提供了在动物,包括人体中抑制PDF的方法,包括按照下文所说明的,向需要治疗的受治疗者给药有效量的式(I)化合物。
