Thirty-three (N-aryl-N-arylsulfonyl)aminoacetohydroxamic acids were synthesized in an effort to develop novel urease inhibitors. Among these compounds, 2-(N-(3-nitrophenyl)-N-(4-tert-butylphenylsulfonyl))aminoacetohydroxamic acid (e2) exhibited excellent inhibitory activity against Helicobacter pylori urease with no perceptible cytotoxicity to mammalian cells. Compound e2 showed over 690-fold higher
为了开发新型脲酶抑制剂,合成了33 种(N-芳基-N-芳基磺酰基)氨基乙酰氧肟酸。在这些化合物中,2-( N- (3-硝基苯基) -N- (4-叔丁基苯磺酰基))氨基乙酰异羟肟酸 ( e2 ) 对幽门螺杆菌脲酶具有出色的抑制活性,对哺乳动物细胞没有明显的细胞毒性。化合物e2显示出比临床使用的尿素酶抑制剂乙酰氧肟酸高 690 倍以上的效力,以混合机制可逆地抑制尿素酶。分子模型显示 ( N -aryl- N-arylsulfonyl)aminoacetohydroxamic acids 可能与 Ni 离子和两个疏水区域结合,呈“Y”形。
