HD5
HD5 is an innate immune effector peptide and SARS-CoV Inhibitor. HD5 binds to the ligand-binding domain of angiotensin-converting enzyme-2 (ACE2) via multiple hydrogen bonds to competitively block the receptor, shielding it from viral recognition. HD5 can be used for the research of COVID-19, HPV16 infection, epithelial ovarian cancer, small-cell lung cancer, and colon cancer.

Actividad biológica
HD5 binds with high affinity to the ligand-binding domain of host cell ACE2, competitively blocking and shielding the receptor to prevent SARS-CoV-2 recognition and infection of host cells[1].
HD5 (20 µM) binds to regions of HPV16 L1 and L2 capsid proteins[2].
HD5 (15 μM; 5 days) significantly inhibits the spread and cytolytic activity of PtDd-deficient mut-Ad3GFP in A549 cells, while only minimally impacting PtDd-producing wt-Ad3GFP[3].
HD5 (0.1 μM) binds to HAdV3 penton base, fiber, fiber knob, and multimeric penton base-containing structures (PtDd and virion-associated penton bases) in a Western blot assay[3].
HD5 significantly inhibits progeny virus production and spread of PtDd-deficient mut-Ad3GFP in Caco-2 and T84 cells, while PtDd-producing wt-Ad3GFP is unaffected[3].
