Information
TW-37 is a novel nonpeptide inhibitor to recombinantBcl-2,Bcl-xLandMcl-1withKiof 0.29 μM, 1.11 μM and 0.26 μM in cell-free assays, respectively.
In vitro
TW-37 targets the BH3-binding groove in Bcl-2 where proapoptotic Bcl-2 proteins bind, and shows higher affinity and selectivity for Bcl-2 and Mcl-1 over Bcl-xL with Ki values of 0.29 μM, 0.26 μM and 1.11 μM, respectively. In vitro, TW-37 shows significant anti-proliferative and pro-apoptotic effect in a de novo chemo-resistant WSU-DLCL2 lymphoma cell line and primary cells obtained from a lymphoma patient without effects on normal peripheral blood lymphocytes. TW-37 exhibits the inhibitory effect on both cell growth and cell death in endothelial cell with IC50 of approximately 1.8 μM without effect on the fibroblasts exposed to the same concentration range as the endothelial cells. In addition, TW37 also shows the anti-proliferation effects in MCF-7, LNCaP, and SLK tumor cell lines with the same or lower concentration range than those required to inhibit endothelial cell growth.
In vivo
TW-37 shows a maximum tolerated dose (MTD) of 40 mg/kg for three i.v. injections in severe combined immunodeficient (SCID) mice when given alone, and enhances tumor inhibitory effect of cyclophosphamide-doxorubicin-vincristine-prednisone (CHOP) regimen. TW-37, administrated by i.v. produces the antiangiogenic effect by decreasing the density of functional human microvessels in the severe combined immunodeficient mouse model of human angiogenesis. The combination of TW-37 and MEK inhibitors synergistically block melanoma cell growth in mice by a significant reduction in tumor volume and tumor mass.
