HTL0041178 (), a potent GPR52 agonist with a promising pharmacokinetic profile and exhibiting oral activity in preclinical models, has been identified. This molecule was the outcome of a judicious molecular property-based optimization approach, focusing on balancing potency against metabolic stability, solubility, permeability, and P-gp efflux.

Orphan GPR52 is emerging as a promising neurotherapeutic target. Optimization of previously reported lead employing an iterative drug design strategy led to the identification of a series of unique GPR52 agonists, such as (), (), and (), with improved potency and efficacy. Intriguingly, compounds and showed greater bias for G protein/cAMP signaling and induced significantly less in vitro desensitization than parent compound , indicating that reducing GPR52 β-arrestin activity with biased agonism results in sustained GPR52 activation.

GPR52 is a highly conserved, brain-enriched, G-coupled orphan G protein-coupled receptor (GPCR) that controls various cyclic AMP (cAMP)-dependent physiological and pathological processes. Stimulation of GPR52 activity might be beneficial for the treatment of schizophrenia, psychiatric disorders and other human neurological diseases, whereas inhibition of its activity might provide a potential therapeutic approach for Huntington's disease. Excitingly, HTL0048149 (HTL'149), an orally available GPR52 agonist, has been advanced into phase I human clinical trials for the treatment of schizophrenia.

Within over 800 members of G-protein-coupled receptors, there are numerous orphan receptors whose endogenous ligands are largely unknown, providing many opportunities for novel drug discovery. However, the lack of an in-depth understanding of the intrinsic working mechanism for orphan receptors severely limits the related rational drug design. The G-protein-coupled receptor 52 (GPR52) is a unique orphan receptor that constitutively increases cellular 5'-cyclic adenosine monophosphate (cAMP) levels without binding any exogenous agonists and has been identified as a promising therapeutic target for central nervous system disorders.
