bcl-b inhibitor 1

Bcl-B inhibitor 1 is an antitumor compound that binds to and inactivates pro-apoptotic proteins in the BH3 structural domain.

Daphnetin (7,8-Dihydroxycoumarin), a natural coumarin derivative, is a protein kinase inhibitor with inhibitory for EGFR (IC50: 7.67 μM), PKA (IC50: 9.33 μM), and PKC (IC50: 25.01 μM), also exhibit anti-oxidant and anti-inflammatory activities.

Gambogic Acid (Guttic Acid) ( EC50=0.78-1.64 uM) activates caspases. Gambogic Acid competitively suppresses Bcl-XL, Bcl-2, Bcl-W, Bcl-B, Bfl-1 and Mcl-1. The IC50s of Gambogic Acid for Bcl-XL, Bcl-2, Bcl-W, Bcl-B, Bfl-1 and Mcl-1 are 1.47, 1.21, 2.02, 0.66, 1.06 and 0.79 uM, respectively.

CAY10404 (3-(4-METHYLSULPHONYLPHENYL)-4-PHENYL-5-T) is a potent and highly selective inhibitor of COX-2 and COX-1. It is also a potent inhibitor of PKB Akt and MAPK signalling pathways and induces apoptosis in NSC-LC cells, with analgesic, anti-inflammatory and anti-cancer activities.

Bcl-2-IN-16 is an inhibitor of Bcl-2 (B-cell lymphoma 2) [1].

MLS-0053105, a chloromaleimide, functions as a selective inhibitor of BFL-1, exhibiting an IC50 of 0.4 µM against Bfl-1 F-Bid. Its inhibitory potency is over tenfold lower for Bcl-W, Bcl-2, and Bcl-XL, and it shows no activity against Bcl-B and Mcl-1.

(S)-Sabutoclax ((S)-BI-97C1), an optically pure derivative of apogossypol, serves as a pan-active inhibitor of the antiapoptotic B-cell lymphoma/leukemia-2 (Bcl-2) family proteins. It effectively blocks the binding of BH3 peptides to key proteins in the family, including Bcl-XL, Bcl-2, Mcl-1, and Bfl-1, displaying inhibitory concentration (IC50) values of 0.31, 0.32, 0.20, and 0.62 μM, respectively. Furthermore, (S)-Sabutoclax demonstrates potent efficacy in inhibiting the growth of various cancer cell lines, such as those from human prostate cancer, lung cancer, and lymphoma, with half-maximal effective concentration (EC50) values of 0.13, 0.56, and 0.049 μM, respectively. This compound is utilized in research focusing on apoptosis-based cancer therapies [1].
