Synthesis, in Vitro Activity, and Three-Dimensional Quantitative Structure−Activity Relationship of Novel Hydrazine Inhibitors of Human Vascular Adhesion Protein-1
摘要:
Vascular adhesion protein-1 (VAP-1) belongs to the semicarbazide-sensitive amine oxidases (SSAOs) that convert amines into aldehydes. SSAOs are distinct from the mammalian monoamine oxidases (MAOs), but their substrate specificities are partly overlapping. VAP-1 has been proposed as a target for anti-inflammatory drug therapy because of its role in leukocyte adhesion to endothelium. Here, we describe the synthesis and in vitro activities of novel series of VAP-1 selective inhibitors. In addition, the molecular dynamics simulations performed for VAP-1 reveal that the movements of Met211, Ser496, and especially Leu469 can enlarge the ligand-binding pocket, allowing larger ligands than those seen in the crystal structures to bind. Combining the data from molecular dynamics simulations, docking, and in vitro measurements, the three-dimensional quantitative structure-activity relationship (3D QSAR) models for VAP-1 (q(LOO)(2): 0.636; r(2:) 0.828) and MAOs (q(LOO)(2): 0.749, r(2): 0.840) were built and employed in the development of selective VAP-1 inhibitors.

types of aliphaticsulfonylhalides (Cl versus F) were compared in parallel synthesis of sulfonamides derived fromaliphatic amines. Aliphaticsulfonyl fluorides showed good results with amines bearing an additional functionality, while the corresponding chlorides failed. Both sulfonylhalides were effective in the reactions with amines having an easily accessible amino group. Aliphaticsulfonyl chlorides
