In this study, researchers investigated the design of novel inhibitors for myeloid cell leukemia-1 (Mcl-1) using pyrrolidine derivatives. They employed three molecular modeling techniques, CoMSIA, CoMFA, and HQSAR, to generate models and analyze the inhibitory activity of Mcl-1. The models were visualized using contours and colored fragments, which provided insights into favorable and unfavorable contributions to the inhibitory activity of Mcl-1. Based on these results, the researchers designed four new compounds, which exhibited higher predicted inhibitory activity. To assess the suitability...
