新出现的SARS-CoV-2感染是全球COVID-19大流行的原因。迄今为止,可用于对抗这种疾病的治疗选择有限。在这里,我们研究了两种广谱抗病毒天然产物诃子酸(CHLA)和安石榴苷(PUG)对SARS-CoV-2病毒复制的抑制能力。CHLA和PUG在非细胞毒性浓度下均通过靶向病毒3-糜蛋白酶样半胱氨酸蛋白酶(3CLpro)作为变构调节剂的酶活性,减少病毒诱导的Vero-E6单层噬斑形成。我们的研究证明了CHLA和PUG作为新型COVID-19疗法的潜在用途。
The emerging SARS-CoV-2 infection is the cause of the global COVID-19 pandemic. To date, there are limited therapeutic options available to fight this disease. Here we examined the inhibitory abilities of two broad-spectrum antiviral natural products chebulagic acid (CHLA) and punicalagin (PUG) against SARS-CoV-2 viral replication. Both CHLA and PUG reduced virus-induced plaque formation in Vero-E6 monolayer at noncytotoxic concentrations, by targeting the enzymatic activity of viral 3-chymotrypsin-like cysteine protease (3CLpro) as allosteric regulators. Our study demonstrates the potential use of CHLA and PUG as novel COVID-19 therapies.
