Potent inhibitor for caspase-3. Ac-DNLD-CHO inhibited caspase-3 (Ki app = 0.68 nM) more selectively than caspase-7, -8, and -9 (Ki app = 55.7, >200, and > 200 nM, respectively).
Ac-Asp-Asn-Leu-Asp-H (aldehyde) is a peptide that is an agonist of the ion channels. It can be used as a research tool in studies on protein interactions and receptor pharmacology. Ac-Asp-Asn-Leu-Asp-H (aldehyde) binds to the ligand binding site of ion channels, which activates or inhibits their function. This peptide has been shown to inhibit the activity of potassium channels and glutamate receptors, and it can be used as an antibody for cell biology and immunology experiments.
