DSR-141562 is a novel, orally active, and selective brain-penetrant phosphodiesterase 1 (PDE1) inhibitor. DSR-141562 shows preferential selectivity for human PDE1B with an IC 50 of 43.9 nM, and the IC 50 values for human PDE1A and 1C are 97.6 and 431.8 nM, respectively. DSR-141562 can be used for the study of positive symptoms, negative symptoms and cognitive impairments associated with schizophrenia.

DSR-141562 (oral administration; 30 mg/kg; single dose; plasma and brain exposures 0.5, 1, 2, and 3 hours after administration) exhibits good brain uptake, with the brain-to-blood concentration ratio of unbound drug being 0.99 in rats.
DSR-141562 (oral administration; 10 mg/kg; single dose; 2 hours) slightly but significantly increases cGMP contents in the frontal cortex and striatum in rat.
DSR-141562 (oral administration; 30 mg/kg or 100 mg/kg; single dose; 2 hours) causes a significant increase in cGMP concentration in monkey CSF. The plasma concentrations of unbound this compound are above 43.9 nM (IC50s)for PDE1B in vitro (43.9 nM). DSR-141562 causes a significant increase in cGMP concentration in monkey CSF.
DSR-141562 (oral administration; 3 mg/kg, 10 mg/kg and 30 mg/kg; single dose) significantly reverses methamphetamine-induced locomotor hyperactivity, but ha
