Description

Description générale

Procaspase-activating compound 1 (PAC-1) is an ortho-hydroxy N-acyl hydrazine compound. It is cytotoxic to a variety of cancer cells, such as lymphoma, leukaemia, breast carcinoma and glioblastoma. High doses of PAC-1 can promote neuroexcitation. It helps in the in vitro autoactivation of the proenzyme protease, which acts as a prototype for other protease activating compounds. PAC-1 dependant activation of procaspase-3 is associated with the chelation of zinc.

Actions biochimiques/physiologiques

PAC-1 is a caspase 3 activator. Caspase activation is a key strategy in cancer therapy. Caspase 3 is a key executioner caspase and direct effector of apoptosis. Hallmark of many cancers is the circumvention of signal in the activation of executioner caspases and loss of apoptotic response. EC₅₀ for caspase 3 activation = 0.33 μM and caspase 7= 4.5 μM. The IC₅₀ for apoptosis induction = 0.92 μM. Elevated caspase 3 level in cancerous cell lines and tissues allows PAC-1 to selectively induce apoptosis in tissues.
