Diaminocyclobutenediones as potent and orally bioavailable CXCR2 receptor antagonists: SAR in the phenolic amide region

Bioorg Med Chem Lett. 2009 Aug 1;19(15):4446-9. doi: 10.1016/j.bmcl.2009.05.049. Epub 2009 May 18.

Abstract

A series of potent and orally bioavailable 3,4-diaminocyclobutenediones with various amide modifications and substitution on the left side phenyl ring were prepared and found to show significant inhibitory activities towards both CXCR2 and CXCR1 receptors.
