Description : Vicriviroc is an inhibitor of CCR5 signaling with IC50 value of 0.91nM [1].The rst step of HIV-1 infection is that the viral envelope, gp120, will interact with cellular coreceptor CCR5. As a second CCR5 antagonist, Vicriviroc can block this interaction and has the antivirus potency. In the chemotaxis assay, Vicriviroc can innhibit chemokine-mediated migration of a mouse Ba/F3 cell line stably expressing recombinant human CCR5 with IC50 value below 1 nM. In the calcium ux assay, Vicriviroc inhibit intracellular calcium release induced by receptor stimulation. Vicriviroc is also proved to inhibit GTPgammaS binding induced by RANTES with mean IC50 of 4.21.3nM in a GTPgammaS exchange assay. In a PBMC infection assay with 30 R5-tropic HIV-1 isolates, Vicriviroc potently inhibits all the viral isolates with geometric mean EC50s ranging between 0.04 nM and 2.3 nM. Activity of vicriviroc against drug-resistant viruses has also been tested. Vicriviroc is effective against all the viruses with de ned RTI, PRI, or fusion inhibitor resistance patterns. Furthermore, engineered viruses containing mutations in the gp41 gene associated with enfuvirtide resistance are completely sensitive to vicriviroc. So far, Vicriviroc has shown good tolerance and partial therapeutic success in phase II clinical trials for HIV [1,2].References:[1] Julie M.
