N-aryl-prolyl-dipeptides as potent antagonists of VLA-4.
The design, synthesis, and biological evaluation of N-arylprolyl-dipeptide derivatives as small molecule VLA-4 antagonists is described. Potency against VLA-4 and alpha(4)beta(7) and rat pharmacokinetic evaluation revealed some advantages over the related N-(arylsulfonyl)-prolyl-dipeptide analogues.
