Source  Crassostrea gigas(hydrolysate of oyster)



Activity Information


Target Organism  HIV

Assay  HIV-1 protease inhibition assay

Activity 

  • [Ref.9918775]HIV-1:inhibition of HIV-1 protease(IC50=20 nM).

Hemolytic Activity  No hemolysis information or data found in the reference(s) presented in this entry

Cytotoxicity 

  • No cytotoxicity information or data found in the reference(s) presented in this entry

Binding Target  HIV-1 protease

Mechanism  The HIV-1 protease is a virally encoded protease that serves to cleave the gag and gag-pol polyprotein precursor into mature, functional proteins. This specific proteolysis occurs late in the viral life cycle and is essential for the maturation of the infectious virus. The peptide inhibits HIV-1 protease and thus acts antiviral activity.
