Replacement of the carbamoyl residue (R) in reference compound 2 by larger residues (e.g.72) strongly affected Y1R affinity. In case of very bulky carbamoyl substituents (e.g.78), an inverted binding mode was suggested by induced-fit docking.
在参考化合物2中,通过较大的残基(例如72)替换羰胺基团(R)强烈影响了Y1R的亲和力。对于非常庞大的羰胺基取代基(例如78),诱导适应对接建议存在一种倒置结合模式。
