Virus Protease
Viral proteases are enzymes encoded by the genetic material (DNA or RNA) of viral pathogens. Viral proteases catalyze the cleavage of specific peptide bonds in viral polyprotein precursors or in cellular proteins. Viral proteases may use different catalytic mechanisms involving either serine, cysteine or aspartic acid residues to attack the scissile peptide bond. Selective recognition of these sequence patterns by a complementary substrate binding site of the enzyme ensures a high degree of specific recognition and cleavage.
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is the cause of the respiratory illness coronavirus disease 2019 (COVID-19). Initial spike protein priming by transmembrane protease, serine 2 (TMPRSS2) is essential for entry of SARS-CoV-2. After a SARS-CoV-2 virion attaches to a target cell, the cell's protease TMPRSS2 cuts open the spike protein of the virus, exposing a fusion peptide.

AH-D peptide
0 ImagesCat. No.: HY-P10862Purity: 99.32%AH-D peptide is a brain-penetrant antiviral agent disrupting highly curved lipid membranes. AH-D peptide exhibits broad-spectrum antiviral activity against ZIKV, Dengue virus, Chikungunya virus, yellow fever virus and Japanese encephalitis virus, with
IC50 values of 11.9, 12.5, 35.7, 206 and 136 nM, respectively. AH-D peptide reduces the viral load in the brain, suppresses inflammation, protects neurons, and does not damage the blood brain barrier. AH-D peptide restores antitumor immunity by decreasing circulating PD-L1+ exosomes, reducing intratumoral immunosuppressive cells (regulatory T cells, myeloid-derived suppressor cells), and enhancing T cell function. AH-D peptide inhibits membrane-enveloped viruses and cancer cell metastasis in vivo. AH-D peptide exhibits no immunogenicity and has negligible effects on normal tissues. AH-D peptide can be used for research in Zika virus and other mosquito-borne viruses, cancer immunotherapy and metastasis.
