VLA-4 is implicated in several inflammatory and autoimmune disease states. A series of cyclic β-amino acids (β-aa) was studied as VLA-4 antagonists. Binding affinity was highly dependent on the dihedral angle (φ{symbol}) between the amino and the carboxyl

Through high throughput screening, substituted proline sulfonamide 6 was identified as HCV NS5b RNA-dependent RNA polymerase inhibitor. Optimization of various regions of the lead molecule resulted in compounds that displayed good potency and selectivity.

The α4β1 and α4β7 integrins are implicated in several inflammatory disease states. Systematic SAR studies of an α4β1-specific arylsulfonyl-Pro-Tyr lead led to the identification of a new α4β7 binding site, best captured by O-carbamates of Tyr for this structural class. Several compounds showed a 200- to 400-fold improvement in α4β7 binding affinity while maintaining subnanomolar α4β1 activity, for example 2l, VCAM-Ig α4β1 IC50=0.13 nM, VCAM-Ig α4β7 IC50=1.92 nM.

N-(3,5-Dichlorophenylsulfonyl)-(R)-thioprolyl biarylalanine 10a has been identified as a potent and specific antagonist of the α4β1 integrin. Altering the configuration of thioproline from R to S led to a series of dual antagonists of α4β1 and α4β7, and the N-acetyl analogue 8b was found to be the most potent dual antagonist. A binding site model for α4β1 and α4β7 is proposed to explain the structure-activity relationship.
