• 产品描述：

  GC376 是一种 3CLpro (3C-like protease) 的抑制剂，对于PEDV 3CLpro的IC50值约为1.11 μM。GC376 对多种冠状病毒（包括SARS-CoV）的3CLpro有活性

• 靶点： PEDV 3CLpro(Cell-free assay):1.11 μM;SARS-CoV

• 体外研究：
  Molnupiravir and GC376 show a synergistic activity on SARS-CoV-2 at 48 h, and an additive activity on SARS-CoV-2 at 72 h

• 体内研究：
  GC376, a dipeptidyl bisulfite adduct salt, is a 3CLpro (3C-like protease) inhibitor that exerts strong inhibitory effects on picornaviruses and coronaviruses, including SARS-CoV.

• 细胞实验： Cell lines: Vero E6 cells Concentrations: 0.21-16.7 μM Incubation Time: 48 and 72 h Method: Vero E6 cells (3000 cells/well) were seeded in 96-well clear flat-bottom plates and incubated at 37°C with 5% CO2 for 24 h. After incubation, cells were infected using a multiplicity of infection (MOI) of 0.1. SARS-CoV-2 was allowed to adsorb for one hour at 37°C. Subsequently, virus inoculum was removed, and cells were overlaid with media containing 3-fold serial dilutions of molnupiravir (0.62-50 μM), nirmatrelvir (0.62-50 μM) and GC376 (0.21-16.7 μM). Negative controls (compounds alone), infected positive controls (SARS-CoV-2 alone) and mock-infected cells were included in each plate. Plates were incubated at 37°C with 5% CO2 for 48 and 72 h and then, cell viability was measured using an MTT reduction assay.

• 动物实验： Animal Models: Female BALB/c mice Dosages: 111 or 55.5 mg/kg Administration: i.m.
