Description

CTEP, also known as RO4956371, is a potent, long-acting, orally bioavailable allosteric antagonist of mGlu5 receptor with IC50 of 2.2 nM. CTEP binds mGlu5 with low nanomolar affinity and shows >1000-fold selectivity when tested against 103 targets, including all known mGlu receptors. CTEP penetrates the brain with a brain/plasma ratio of 2.6 and displaces the tracer ABP688 in vivo in mice from brain regions expressing mGlu5 with an average ED(50) equivalent to a drug concentration of 77.5 ng/g in brain tissue.

How to use

In Vitro:

CTEP was used at 0.03-0.1 µM final concentration in vitro and in cellular assays.

In Vivo:

CTEP was orally dosed to mice at single 0.1-1.0 mg/kg, or with a dose of 2 mg/kg orally every 48 h for 2 months. CTEP was orally dose at 2 mg/kg BID achieves uninterrupted mGlu5 occupancy per 48 hours in mice.
