Description of YH-53

YH-53 is a potent 3CLpro inhibitor with Ki values of 6.3 nM, 34.7 nM for SARS-CoV-1 3CLpro and SARS-CoV-2 3CLpro, respectively. YH-53 strongly blocks the SARS-CoV-2 replication. YH-53 is a peptidomimetic compound with a unique benzothiazolyl ketone. YH-53 has the potential for COVID-19 research[1][2].

YH-53 (1-25 μM; for 24 h) efficiently reduces copies of total RNA with increased concentrations in VeroE6/TMPRSS2 cells[1]. YH-53 (1, 5, 10, 15, 20, 25 μM; for 48 h) with 10 μM completely blocks the viral proliferation against SARS-CoV-2 were examined by a cytopathic effect (CPE) assay in Vero cells[1]. YH-53 (10, 100 μM; for 24 h) has no cytotoxicity with a CC50 value of >100 μM in vero cells[1]. YH-53 (10 μM) moderately inhibits CYP1A2, CYP2D6, and CYP2C8 (26.6%, 38.0%, 66.4%, respectively). YH-53 has no inhibition on CYP2C9 and CYP3A4[1]. YH-53 inhibits SARS-CoV 3CLpro with an IC50 of 0.74 μM.

YH-53 (0.1 mg/kg; iv) has a T1/2 of 2.97 hours, an AUC0-∞ of 19.7 ng•h/mL, a Vd of 3.51 L/kg in rats[1]. YH-53 (0.5 mg/kg; oral) has a T1/2 of 9.64 hours, an AUC0-∞ of 3.49 ng•h/mL, a Cmax of 1.08 ng/mL in rats[1].

Calculation results:

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL saline, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
3. All of the above co-solvents are available for purchase on the GlpBio website.
