Biological Activity

Q-VD-OPh is a potent, irreversible pan-caspase inhibitor with IC50 ranging from 25 to 400 nM for caspases 1, 3, 8, and 9, showing inhibitory effects on terminal caspase activation, substrate cleavage, and DNA ladder formation associated with apoptosis.

Method cell viability
Cell Lines Caco-2 cells
Concentrations 50 μM
Incubation Time 6 h
Results Giardia-induced Caco-2 cell apoptosis was dependent on CASP3/8 activation, as co-incubation of Caco-2 cells with Q-VD-O weakened the ability of trophozoites to induce apoptosis after 6 h of incubation.

Incubation Time 24 h
Results Our results showed that Q-VD-OPH inhibits spontaneous cell death of CD4+ T cells isolated from peripheral lymph nodes (LNs) (axillary and inguinal) and spleen of SIVinfected RMs

Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.

Cimiside E

Cimiside E (25-Anhydrocimigenol xyloside) possesses apoptotic action on gastric cancer cells, with an IC50 value of 14.58 μM. Cimiside E induces cell cycle arrest at G2/M phase, and mediates apoptosis through the induction of the caspase cascade for both the extrinsic and intrinsic pathways.

Trijuganone C

Trijuganone C, a natural product extracted from Salvia miltiorrhiza, inhibits the proliferation of cancer cells through induction of apoptosis mediated by mitochondrial dysfunction and caspase activation.

QM31

QM31 (SVT016426), a cytoprotective agent, is a selective inhibitor of Apaf-1. QM31 inhibits the formation of the apoptosome (IC50=7.9μM), the caspase activation complex composed by Apaf-1, cytochrome c, dATP and caspase-9. QM31 exerts mitochondrioprotective functions and interferes with the intra-S-phase DNA damage checkpoint.

Penicillic acid 

Penicillic acid is a polyketide mycotoxin produced by several species of Aspergillus and Penicillium. Penicillic acid exhibits cytotoxicity in rat alveolar macrophages (AM) in vitro. Penicillic acid inhibits Fas ligand-induced apoptosis by blocking self-processing of caspase-8.

δ-Secretase inhibitor 11 

δ-Secretase inhibitor 11 (compound 11) is an orally active, potent, BBB-penetrated, non-toxic, selective and specific δ-secretase inhibitor, with an IC50 of 0.7 μM. δ-Secretase inhibitor 11 interacts with both the active site and allosteric site of δ-secretase.
