S6852 Gossypol

Gossypol (BL 193) is an orally-active polyphenol isolated from cotton seeds and roots. Gossypol is a potent inhibitor of 5α-reductase 1 and 3α-hydroxysteroid dehydrogenase with IC50 of 3.33 μM and 0.52 μM in cell-free assay, respectively. Gossypol also inhibits the binding of BH3 peptide to Bcl protein with IC50 of 0.4 μM and 10 μM for Bcl-XL and Bcl-2, respectively. Gossypol induces apoptosis and cell growth inhibition in various cancer cells.

Selective Bcl-xL, IC50: 0.4 μM
S8177 BH3I-1

BH3I-1 is a Bcl-XL-BH3 domain interaction inhibitor with Ki of 2.4 μM (by fluorescence polarization ).It is a selective inhibitor of Bcl-2 family proteins.

Selective BH3-Bcl-xL interaction, Ki: 2.4 μM
S5600 Flavokawain A

Flavokawain A, extracted from kava, is an apoptotic inducers and anticarcinogenic agent. Flavokawain A can down-regulation of antiapoptotic proteins, such as XIAP, survivin, and Bcl-xL, thereby changing the balance between apoptotic and antiapoptotic molecules and then induce cell death in tumor cells.

S5967 Berberine chloride hydrate

Berberine (Natural Yellow 18) chloride hydrate is a quaternary ammonium salt from the group of isoquinoline alkaloids. Berberine activates caspase 3 and caspase 8, cleavage of poly ADP-ribose polymerase (PARP) and the release of cytochrome c. Berberine chloride decreases the expression of c-IAP1, Bcl-2 and Bcl-XL. Berberine chloride induces apoptosis with sustained phosphorylation of JNK and p38 MAPK, as well as generation of

Selective
S8924 DT2216

DT2216 is a potent and selective degrader of BCL-XL based on PROTAC technology. DT2216 inhibits various BCL-XL-dependent leukemia and cancer cells but considerably less toxic to platelets.

S2271 Berberine chloride (NSC 646666)

Berberine chloride (NSC 646666, Natural Yellow 18) is a quaternary ammonium salt from the group of isoquinoline alkaloids. Berberine activates caspase 3 and caspase 8, cleavage of poly ADP-ribose polymerase (PARP) and the release of cytochrome c. Berberine chloride decreases the expression of c-IAP1, Bcl-2 and Bcl-XL. Berberine chloride induces apoptosis with sustained phosphorylation of JNK and p38 MAPK, as well as generation
