Abstract :
A novel series of cyclobutenedione centered C(4)-alkyl substituted furanyl analogs was developed as potent CXCR2 and CXCR1 antagonists. Compound 16 exhibits potent inhibitory activities against IL-8 binding to the receptors (CXCR2 Ki = 1 nM, IC50 = 1.3 nM; CXCR1 Ki = 3 nM, IC50 = 7.3 nM), and demonstrates potent inhibition against both Gro-α and IL-8 induced hPMN migration (chemotaxis: CXCR2 IC50 = 0.5 nM, CXCR1 IC50 = 37 nM). In addition, 16 has shown good oral pharmacokinetic profiles in rat, mouse, monkey, and dog.
