β‐difluorinated cycloaliphatic amino acids, a library of new dipeptide nitriles was evaluated as human cathepsin inhibitors. The orientation of the fluorinated face relative to the protein structure of cathepsin B was elucidated by molecular modeling and NMR studies (see figure). For (R)‐configured eutomers, the fluorine atoms are directed to the S2 pocket, whereas in (S)‐configured distomers, the fluorinated face
氟还是氟?基于β,β-二氟环脂族氨基酸,新的二肽腈文库被评估为人组织蛋白酶抑制剂。通过分子建模和NMR研究阐明了氟化面相对于组织蛋白酶B蛋白质结构的方向(见图)。对于(R)配置的体,氟原子被定向到S 2凹穴,而在(S)配置的dis体中,氟化面暴露在溶剂中。
