Pavinetant (MLE-4901) is a neurokinin-3 receptor (NK3R) antagonist.

IC50 & Target


In Vitro

Pavinetant (AZD2624) is a potent and selective NK3 receptor antagonist which is developed for the treatment of schizophrenia. Pavinetant exhibits an inhibitory effect on microsomal CYP3A4/5 activities with apparent IC50 values of 7.1 and 19.8 μM for midazolam and testosterone assays, respectively. No time-dependent inactivation of CYP3A4/5 activity by Pavinetant is observed. Pavinetant demonstrates weak to no inhibition of CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19, and CYP2D6[1].

Kinase Assay

The potential of Pavinetant (AZD2624) to cause time-dependent inhibition of CYP3A activities is evaluated by pre-incubating 10 μM of Pavinetant at 37°C for 0, 3, 10, 20, and 30 min in 0.1 M pH 7.4 phosphate buffer incubation mixture (0.2 mL) containing 2 mg/mL HLM and 1 mM NADPH. Verapamil, tested at 10 μM, is also incubated separately as a positive control. An aliquot of 20 μL is removed from pre-incubation tube at each time point and added to a secondary 5-min incubation (180 μL) containing 15 μM of midazolam and 1 mM of NADPH. The formation of 1′-hydroxymidazolam is used as the marker activity for CYP3A enzymes and analyzed using LC-MS. CYP3A enzyme activities after pre-incubation with Pavinetant are compared to activities following incubation with vehicle solvent (1% methanol) and without pre-incubation[1].
