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.

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

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.
