生化／生理作用
Compound 52 (C52) is an orally active, brain-penetrant, highly potent and selective prostaglandin E2 (PGE2) receptor 2 (EP2) antagonist (h/r/m EP2 IC50 = 8/10/10 nM against PGE2 binding, IC50 = 5/3/4 nM against 10 nM PGE2-induced cellular cAMP) with ∼4000-fold selectivity over other EP receptors (hEP1/3/4 IC50 >30 μM against PGE2 binding; hCRTH2/DP/IP/TP IC50 >33 μM against LTD4-induced cellular Ca2+) and no CYP inhibitory potency. C52 reduces inflammatory neurodegeneration in a murine model of cerebral ischemia (10 mg/kg p.o. 4.5h & 24h post MCAO) and restores cognition in aged mice (10 mg/kg/d p.o.) by rejuvenating cellular bioenergetics in vivo.

A high-throughput screen resulted in the discovery of benzoxazepine 1, an EP2 antagonist possessing low microsomal stability and potent CYP3A4 inhibition. Modular optimization of lead compound 1 resulted in the discovery of benzoxazepine 52, a molecule with single-digit nM binding

Ageing is characterized by the development of persistent pro-inflammatory responses that contribute to atherosclerosis, metabolic syndrome, cancer and frailty1-3. The ageing brain is also vulnerable to inflammation, as demonstrated by the high prevalence of age-associated cognitive decline and Alzheimer's disease4-6.
