Discovery of Novel p-Arylthio Cinnamides as Antagonists of Leukocyte Function-Associated Antigen-1/Intercellular Adhesion Molecule-1 Interaction. 4. Structure−Activity Relationship of Substituents on the Benzene Ring of the Cinnamide
摘要:
We have shown that p-arylthio cinnamides can inhibit the interaction of LFA-1 and ICAM-1, which is involved in cell adhesion and the inflammatory process. We now show that 2,3-disubstitution on the aryl portion of the cinnamide results in enhanced activity over mono substitution on the ring. The best 2,3-substituents were chlorine and trifluoromethyl groups. Compounds 39 and 40 which contain two CF3 groups have IC50 values of 0.5 and 0.1 nM, respectively, in inhibiting JY8 cells expressing LFA-1 on their surface, from adhering to ICAM-1. The structure-activity relationship (SAR) was examined using an NMR based model of the LFA-1 I domain/compound 31 complex. One of our compounds (38) was able to reduce cell migration in two different in vivo experiments.
