HTL14242 (HTL0014242) is an advanced, orally active and potent mGlu5 NAM with a pKi and pIC50 value of 9.3 and 9.2, respectively[1]. HTL14242 can be used for the study of Parkinson’s disease[2].

IC50 & Target[1]



In Vitro

HTL14242 is stable in rat plasma, inactive at the hERG ion-channel, and has a clean profile in vitro assays of cytotoxicity in HepG2 cells, the TC50 is >90 μM[1].

In Vivo

HTL14242 (oral administration; 1, 3, or 10 mg/kg; sacrificed 1 h postdose) emonstrates an excellent, dose-dependent occupancy of mGlu5 receptors from an oral dose, with an estimated ED50 of 0.3 mg/kg[1].
HTL14242 (oral administration; 1 mg/ml) exhibits an oral PK Profile, the t1/2, AUCinf and F% are 6.5 hours, 3946 ng/h/mL and 80%, respectively in dog[1].

Animal Model: Dog (PK study)[1]
Dosage: 3, 10 and 30 mg/kg
Administration: Oral administration; single dose
Result: Had a good PK characteristics in dogs.
