S0354 Alsterpaullone

Alsterpaullone (Alp, 9-Nitropaullone, NSC 705701) is a potent inhibitor of CDK with IC50 of 35 nM, 15 nM, 200 nM and 40 nM for CDK1/cyclin B, CDK2/cyclin A, CDK2/cyclin E and CDK5/p35, respectively. Alsterpaullone also acts as a potent inhibitor of glycogen synthase kinase-3 (GSK-3) with IC50 of both 4 nM for GSK-3α and GSK-3β. Alsterpaullone induces apoptosis by activation of caspase-9. Alsterpaullone has antitumor activity and possesses potential for the treatment o


Z-LEHD-FMK TFA (Caspase-9 Inhibitor) is a cell-permeable, competitive and irreversible inhibitor of enzyme caspase-9, which helps in cell survival.


Ac-DEVD-CHO (Caspase-3 Inhibitor I, N-Ac-Asp-Glu-Val-Asp-CHO) is a potent aldehyde inhibitor of Group II caspases with Ki values of 0.2 nM and 0.3 nM for for caspase-3 and caspase-7, respectively. Weak inhibition for caspase-2.

Pan Caspase-9, Ki: 60 nM
S7311 Q-VD-Oph

Q-VD-Oph (Quinoline-Val-Asp-Difluorophenoxymethylketone) is a potent pan-caspase inhibitor with IC50 ranged from 25 to 400 nM for caspases 1,3,8, and 9. Q-VD-OPh can inhibits HIV infection.

Pan Caspase-9, IC50: 25 nM-400 nM
S3275 Senkyunolide I

Senkyunolide I (SEI, SENI) is an orally active compound isolated from Ligusticum chuanxiong with analgesic, anti-migraine, neuroprotective, anti-oxidation and anti-apoptosis activities. Senkyunolide I (SEI, SENI) up-regulates the phosphorylation of Erk1/2 and induces Nrf2 nuclear translocation with enhanced HO-1 and NQO1 expressions. Senkyunolide I (SEI, SENI) promotes the ratio of Bcl-2/Bax and inhibits the expressions of cleaved caspase 3 and caspase 9.

S4353 Terfenadine

Terfenadine is an antihistamine, generally completely metabolizes to the active form fexofenadine in the liver by the enzyme cytochrome P450 CYP3A4 isoform. Terfenadine ((±)-Terfenadine) is a potent open-channel blocker of hERG with an IC50 of 204 nM. Terfenadine, an H1 histamine receptor antagonist, acts as a potent apoptosis inducer in melanoma cells through modulation of Ca2+ homeostasis. Terfenadine induces ROS-dependent apoptosis, simultaneously activates Caspase-4, -2, -9.

S3224 Cinobufagin

Cinobufagin (Cinobufagine), an active ingredient of Venenum Bufonis, inhibits tumor development. Cinobufagin increases ATM and Chk2 and decreases CDC25C, CDK1, and cyclin B. Cinobufagin inhibits PI3K, AKT and Bcl-2 while increases levels of cleaved caspase-9 and caspase-3. Thus, Cinobufagin induces cell cycle arrest at the G2/M phase and apoptosis.
