Abstract:
:We describe herein a novel series of 3-amino-4-hydrazine-cyclobut-3-ene-1,2-diones as potent and selective inhibitors against the CXCR2 chemokine receptor and IL-8-mediated chemotaxis of a CXCR2-expressing cell line. Furthermore, these alkyl-hydrazine series inhibitors such as 5b demonstrated acceptable metabolic stability when incubated in human and rat microsomes.
