  Substituted N-(3,5-Dichlorobenzenesulfonyl)-l-prolyl-phenylalanine analogues as potent VLA-4 antagonists

  摘要：

  A series of substituted N-(3,5-dichlorobenzenesulfonyl)-L-prolyl- and alpha-methyl-L-prolyl-phenylalanine derivatives was prepared as VLA-4/VCAM antagonists. The compounds showed excellent potency with a wide variety of neutral, polar, electron withdrawing or donating groups on the phenylalanine ring (IC50 similar to I nM). Heteroaryl ring substitution for phenylalanine was also well tolerated. Pharmacokinetic studies in rat were performed on a representative set of compounds in both series.

  The discovery of small molecule carbamates as potent dual α4β1/α4β7 integrin antagonists

  摘要：

  The alpha(4)beta(1) and alpha(4)beta(7) integrins are implicated in several inflammatory disease states. Systematic SAR studies of an alpha(4)beta(1)-specific arylsulfonyl-Pro-Tyr lead led to the identification of a new alpha(4)beta(7) binding site, best captured by O-carbamates of Tyr for this structural class. Several compounds showed a 200- to 400-fold improvement in alpha(4)beta(7) binding affinity while maintaining subnanomolar alpha(4)beta(1) activity, for example 21, VCAM-Ig alpha(4)beta(1) IC50 = 0.13 nM. VCAM-Ig alpha(4)beta(7) IC50 = 1.92 nM. (C) 2002 Elsevier Science Ltd. All rights reserved.
