[PMID: 37570705 PMCID: PMC10420183 DOI: 10.3390/molecules28155734] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Revised: 07/21/2023] [Accepted: 07/26/2023] [Indexed: 08/13/2023] Open
Abstract
An oxidant-free and highly efficient synthesis of phenolic quinazolin-4(3H)-ones was achieved by simply stirring a mixture of 2-aminobenzamides, sulfonyl azides, and terminal alkynes. The intermediate N-sulfonylketenimine underwent two nucleophilic additions and the sulfonyl group eliminated through the power of aromatization. The natural product 2-(4-hydroxybenzyl)quinazolin-4(3H)-one can be synthesized on a large scale under mild conditions with this method.

Abstract
Venezuelan and eastern equine encephalitis viruses (VEEV and EEEV, respectively) are mosquito-borne, neuroinvasive human pathogens for which no FDA-approved therapeutic exists. Besides the biothreat posed by these viruses when aerosolized, arthropod transmission presents serious health risks to humans, as demonstrated by the 2019 outbreak of EEE disease in the United States that resulted in 38 confirmed cases, 19 deaths, and neurological effects in survivors. Here, we describe the discovery of a 2-pyrrolidinoquinazolinone scaffold, efficiently synthesized in two to five steps, whose structural optimization resulted in profound antiviral activity. The lead quinazolinone, BDGR-49, potently reduced cellular VEEV and EEEV titers by >7 log at 1 μM and exhibited suitable intravenous and oral pharmacokinetic profiles in BALB/c mice to achieve excellent brain exposure. Outstanding in vivo efficacy was observed in several lethal, subcutaneous infection mouse models using an 8-day dosing regimen. Prophylactically administered BDGR-49 at 25 mg kg-1 per day fully protected against a 10× LD50 VEEV Trinidad donkey (TrD) challenge in BALB/c mice. Similarly, we observed 70% protection when 10× LD50 EEEV FL93-939-infected C57BL/6 mice were treated prophylactically with BDGR-49 at 50 mg kg-1 per day. Last, we observed 100% therapeutic efficacy when mice, challenged with 10× LD50 VEEV TrD, were dosed at 48 hours after infection with BDGR-49 at 25 mg kg-1 per day. Mouse brain viral titers at 96 hours after infection were reduced to values near the limit of detection. Collectively, these results underscore the substantial development potential of a well-tolerated, brain-penetrant lead compound that shows promise in preventing and treating encephalitic alphavirus disease.

Abstract
![]()
Venezuelan and eastern
equine encephalitis viruses are disease-causing,
neuropathic pathogens with no approved treatment options in humans.
While expanding the pharmacophoric model of antialphaviral amidines
prepared via a quinazolinone rearrangement, we discovered that diamine-treated,
2-dihalomethylquinolinones unexpectedly afforded ring-expanded piperazine-fused
benzodiazepinones. Notably, this new chemotype (19 examples) showed
potent, submicromolar inhibition of virus-induced cell death, >7-log
reduction of viral yield, and tractable structure–activity
relationships across both viruses. Antiviral activity was confirmed
in primary human neuronal cells. A mechanistic rationale for product
formation is proposed, and key structural elements were comparatively
modeled between a similarly substituted antiviral amidine and piperazinobenzodiazepinone
prototypes to guide future antiviral development.

Abstract
A highly efficient 2-chloroquinazolin-4(3H)-one rearrangement was developed that predictably generates either twisted-cyclic or ring-fused guanidines in a single operation, depending on the presence of a primary versus secondary amine in the accompanying diamine reagent. Exclusive formation of twisted-cyclic guanidines results from pairing 2-chloroquinazolinones with secondary diamines. Use of primary amine-containing diamines permits a domino quinazolinone rearrangement/intramolecular cyclization, gated through (E)-twisted-cyclic guanidines, to afford ring-fused N-acylguanidines. This scalable, structurally tolerant transformation generated 55 guanidines and delivered twisted-cyclic guanidines with robust plasma stability and an abbreviated total synthesis of an antitumor ring-fused guanidine (4 steps, 55 % yield).
