Caspase 6 Activator

Oosporein is a microbial metabolite and a red crystalline toxin produced by various fungi. Oosporein can promote the reproduction of fungi in host bodies by inhibiting insect immunity, and possesses multiple activities such as antibacterial, antiviral (HSV), and insecticidal effects. Oosporein can inhibit plant growth. In addition, Oosporein can also induce apoptosis, cell membrane damage, oxidative stress, and mitochondrial damage. Oosporein has certain antitumor activity.

SP-6-27 is a tubulin depolymerizing agent that binds to the colchicine site of β-tubulin. SP-6-27 induces G₂/M cell cycle arrest in ovarian cancer cells. SP-6-27 enhances intrinsic apoptosis in ovarian cancer cells through upregulation of Bax, Apaf-1, caspase-6, caspase-9, and caspase-3. SP-6-27 reduces ovarian cancer cell migration. SP-6-27 inhibits capillary tube formation by human umbilical vein endothelial cells. SP-6-27 shows minimum cytotoxicity to normal ovarian epithelia. SP-6-27 shows enhanced cytotoxicity in chemo-sensitive/resistant ovarian cancer cells when combined with Cisplatin (HY-17394). SP-6-27 can be used for the research of ovarian cancer.

Procaspase-3/6 activator 1 (compound 1541) is a highly specific and robust activator of executioner procaspases-3 and -6, with EC₅₀ values of 2.4 ± 0.2 and 2.8 ± 0.3 μM, respectively. Procaspase-3/6 activator 1 does not activate procaspases-1 or -7.
