Amino Acid Sequence

NAc-Ile-Glu-Thr-Asp-pNA

Application

Chromogenic substrate for caspase 8 and granzyme B.

Biochem/physiol Actions

IETD is the sequence of amino acid residues 172-175 of procaspase 3, which is cleaved during apoptosis to produce the p12 subunit and a p20 peptide that is further cleaved to form the p17 subunit of mature caspase 3.

As one of the most prevalent malignancies, breast cancer still remains a significant risk for public health. Common therapeutic strategies include invasive surgery, chemotherapy and anti-herceptin antibodies. Adverse effects, drug resistance and low efficacy of current therapies necessitates the emergence

Copper complexes with potent anti-tumor effect have been extensively developed. Most investigations of their modes of action focused on the biomolecular targets but not the signal transduction between target binding and cell death. We have previously shown that the cytotoxic

Synthetic cathinones have emerged in recreational drug markets as legal alternatives for classical amphetamines. Though currently banned in several countries, 3,4-methylenedioxypyrovalerone (MDPV) is one of the most commonly abused cathinone derivatives worldwide. We have recently reported the potential of MDPV

Apoptosis plays critical roles in multiple biological processes in multicellular organisms. Caspases are known as important participators and regulators of apoptosis. Here, four novel caspase genes of Spodoptera exigua were cloned and characterized, which were designated as SeCasp-1, SeCasp-6, SeCasp-7
