Venezuelan equine encephalitis virus (VEEV) is an emerging pathogenic alphavirus that can cause significant disease in humans. Given the absence of therapeutic options available and the significance of VEEV as a weaponized agent, an optimization effort was initiated around a quinazolinone screening hit with promising cellular antiviral activity (EC50 = 0.8 μM), limited cytotoxic liability (CC50 > 50 μM), and modest in vitro efficacy in reducing viral progeny (63-fold at 5 μM). Scaffold optimization revealed a novel rearrangement affording amidines, specifically compound I, which was found to potently inhibit several VEEV strains in the low nanomolar range without cytotoxicity (EC50 = 0.02-0.04 μM, CC50 > 50 μM) while limiting in vitro viral replication (EC90 = 0.17 μM). Brain exposure was observed in mice with I. Significant protection was observed in VEEV-infected mice at 5 mg kg-1 day-1 and viral replication appeared to be inhibited through interference of viral nonstructural proteins.
Journal of Medicinal Chemistry published new progress about Amidines Role: PAC (Pharmacological Activity), SPN (Synthetic Preparation), THU (Therapeutic Use), BIOL (Biological Study), PREP (Preparation), USES (Uses). 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Electric Literature of 112-63-0.
