Description

Maraviroc is an antiviral, potent, non-competitive CKR-5 receptor antagonist that inhibits binding of HIV viral coat protein gp120. Maraviroc inhibits MIP-1β-stimulated γ-S-GTP binding to HEK-293 cell membranes, indicating its ability to inhibit chemokine-dependent stimulation of GDP-GTP exchange at the CKR-5/G protein complex. Maraviroc also inhibits the downstream event of chemokine-induced intracellular calcium redistribution.

How to use

In Vitro:

Maraviroc inhibits MIP-1β-stimulated γ-S-GTP binding to HEK-293 cell membranes, indicating its ability to inhibit chemokine-dependent stimulation of GDP-GTP exchange at the CCR5/G protein complex. Maraviroc also inhibits the downstream event of chemokine-induced intracellular calcium redistribution, with IC50s ranging from 7 to 30 nM obtained against MIP-1β, MIP-1α and RANTES. In the same experiments, Maraviroc does not trigger release of intracellular calcium at concentrations up to 10 μM, indicating that it is devoid of CCR5 agonist activity. Consistent with this, Maraviroc fails to induce CCR5 internalization. Maraviroc is active at low nanomolar concentrations against HIV-1 Ba-L. Maraviroc inhibits all 200 pseudotyped viruses with a geometric mean IC90 of 13.7 nM. At concentrations >1000 times the 50% inhibitory concentration, maraviroc did not inhibit other chemokine receptors (CCR1, 2, 3, 4, 7, and 8; CXCR1 and 2) to a clinically relevant degree.

In Vivo:

The half-life values of Maraviroc are 0.9 hour in the rat and 2.3 hours in the dog. Following oral administration (2 mg/kg) to the dog, the Cmax (256 ng/ml) occurred 1.5 hours post-dose, and the bioavailability is 40%. For the rat, approximately 30% of the administered dose is absorbed from the intestinal tract. Female RAG-hu mice are challenged vaginally with HIV-1 an hour after intravaginal application of the Maraviroc gel. Maraviroc gel treated mice are fully protected against vaginal HIV-1 challenge in contrast to placebo gel treated mice which all became infected. Vaginal administration of Maraviroc fully protects mice against HIV-1 vaginal challenge. While there is a clear pattern of CD4 T cell decline in placebo-gel treated and viral challenged mice, their levels are stable in mice receiving Maraviroc gel.
