In vitro
As a potent inhibitor of Bcl-2, TW-37 can inhibit recombinant Bcl-2, Bcl-X(L), and Mcl-1 with Ki of 290 nM,110 nM and 260 nM. And TW-37 shows selectivity for Bcl-X(L). For cell lines, TW-37 showed significant antiproliferative effect to WSU-DLCL(2) lymphoma cell line and primary cells. TW-37 disrupted heterodimer formation between Bax and antiapoptotic proteins including Mcl-1, Bcl-2, and Bcl-X(L). TW-37 inhibited cell growth in a dose- and time-dependent manner. This was accompanied by increased apoptosis and concomitant attenuation of NF-kappaB, and downregulation of NF-kappaB downstream genes such as MMP-9 and VEGF, resulting in the inhibition of pancreatic cancer cell migration, invasion and angiogenesis in vitro. And TW-37 can cause apoptotic death.
In vivo
In Colo-357 human PC xenografts in SCID mice, TW-37 treatment signi?cantly inhibited tumor growth. TW-37 could affect the function of NF-kappaB in vivo, and the expression of VEGF, MMP-9, COX-2, Cyclin D1 and Survivin was also downregulated in TW-37-treated animals.
