TW-37 is a Bcl-2 protein family inhibitor with a Ki of 0.29 μM. TW-37 binds to the BH3 binding groove in Bcl-2 protein competing with BH3 peptides derived from Bid, Bim, and Bad proteins. TW-37 binds to Bcl-2 with a Ki value of 290 nM and also to Bcl-xL and Mcl-1 with high affinities. TW-37 potently inhibits cell growth in PC-3 prostate cancer cells with an IC50 value of 200 nM and effectively induces apoptosis in a dose-dependent manner. TW-37 has an IC50 of 1.1 μM for primary human endothelial cells and averaged 0.3 μM for head and neck cancer cells (OSCC3, UM-SCC-1, and UMSCC-74A).

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 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 resveratrol of 11.2 mg/kg.

Preclinical studies of TW-37, a new nonpeptidic small-molecule inhibitor of Bcl-2, in diffuse large cell lymphoma xenograft model reveal drug action on both Bcl-2 and Mcl-1.
