Background:

IT1t dihydrochloride is a potent antagonist of CXCR4 with IC50 value of 8.0 nM [1].

C-X-C chemokine receptor type 4 (CXCR4) is an α-chemokine receptor for chemokine CXCL12. CXCR4 functions as a coreceptor for human immunodeficiency virus (HIV) envelope protein gp-120 and mediates infection of T-cells by HIV [1].

IT1t dihydrochloride is a potent CXCR4 antagonist. In binding assays, IT1t exhibited IC50 values of 8.0 and 11.0 nM for human and rat CXCR4, respectively. In Ca2+ mobilization assays, IT1t exhibited IC50 value of 1.1 nM. In the HIV attachment assay, IT1t inhibited HIV attachment with IC50 and IC90 values of 7 and 100 nM, respectively and inhibited both CXCR4/CXCL12 and CXCR4/gp120 interactions. IT1t exhibited 32% oral bioavailability.
