2'-Deoxy, 3'-deoxy, and 2',3'-dideoxyribosyl surrogates of isoleucyl and methionyl sulfamate adenylates have been investigated to identify the pharmacophoric importance of the ribose group for the inhibition of Escherichia coli methionyl-tRNA (MRS) and isoleucyl-tRNA (IRS) synthetases. Molecular modeling of 2',3'-dideoxyribosyl Met-NHSO2-AMP (9) with the crystal structure of E. coli MRS revealed that
已经研究了异亮氨酰和甲硫氨酸氨基磺酸腺苷酸的2'-脱氧,3'-脱氧和2',3'-二脱氧核糖基替代物,以鉴定核糖基团对抑制大肠杆菌甲硫氨酸-tRNA(MRS)和异亮氨酰-tRNA(IRS)合成酶。具有大肠杆菌MRS晶体结构的2',3'-二脱氧核糖基Met-NHSO2-AMP(9)的分子模型表明,核糖之间缺少两个氢键可弥补核糖上两个羟基的缺乏环氧和His24,导致活性降低较小。
