13C NMR and mass spectrometry studies have been used to demonstrate that the inhibition of α-chymotrypsin by N-sulfonylhydroxymethylpyrrole inhibitors (10) is non-covalent. Hydroxyalkylpyrroles in which an electron-withdrawing group (acyl substituent) is introduced at the alternative C2 position have been synthesised and also shown to inactivate α-chymotrypsin. SAR studies on this class suggests that the incorporation of phenylalanine at C2 is favoured, however, there is little gain in introducing a hydrophobic substituent at C5.
13C NMR 和质谱研究已用于证明 N-磺酰羟甲基吡咯抑制剂 (10) 对 α-胰凝乳蛋白酶的抑制是非共价的。已合成了在替代的 C2 位置引入吸电子基团(酰基取代基)的羟基烷基吡咯,并且还显示出可使 α-胰凝乳蛋白酶失活。对此类的 SAR 研究表明,在 C2 处掺入苯丙氨酸是有利的,但在 C5 处引入疏水取代基几乎没有什么好处。
