Description: UMI-77 is selective Mcl-1 SMI inhibitor. UMI-77 blocks pancreatic cancer growth in vitro and in vivo. MI-77 binds to the BH3-binding groove of Mcl-1 with Ki of 490 nmol/L, showing selectivity over other members of the antiapoptotic Bcl-2 family. UMI-77 inhibits cell growth and induces apoptosis in pancreatic cancer cells in a time- and dose-dependent manner, accompanied by cytochrome c release and caspase-3 activation. In an in vivo BxPC-3 xenograft model, UMI-77 effectively inhibited tumor growth. Western blot analysis in tumor remnants revealed enhancement of proapoptotic markers and significant decrease of survivin.

More Info:

Biological target: UMI-77 is a selective Mcl-1 inhibitor, which shows high binding affinity to Mcl-1 (IC50=0.31 μM). UMI-77 binds to the BH3 binding groove of Mcl-1 with Ki of 490 nM, showing selectivity over other members of anti-apoptotic Bcl-2 members.
In vitro activity: Since attenuation of MCL-1 by RNA interference lowered the threshold at which KYSE150 and KYSE510 cells undergo apoptosis and led to sensitization of these cells to undergo apoptosis triggered by cisplatin (Figs. 55 and 66), a small molecule inhibitor of MCL-1 might also enhance the sensitivity of ESCC cells to this chemotherapy drug. UMI-77, a recently characterized MCL-1-specific inhibitor, was used to investigate the possibility. KYSE150 and KYSE510 cells were treated with UMI-77 for 48 h. Apoptosis was up-regulated in a dose dependent manner, as indicated by the presence of cleaved caspase-3 and cleaved PARP in these cell lines (Fig. 7a and b). As expected, KYSE150 cells with higher BCL-xL level showed less sensitive to UMI-77 and less susceptible to apoptosis than did KYSE510 cells (Fig. 1a and b , Fig. 7c ). Co-immunoprecipitation data indicated that treatment of UMI-77 resulted in disruption of the endogenous MCL-1/BAX (Fig. 8a and c) and MCL-1/BAK (Fig. 8b and d) interactions in both KYSE150 and KYSE510 cells, which were in line with a previous report.

In vivo activity: Daily treatment with UMI-77 for 5 consecutive days a week for two weeks resulted in statistically significant tumor growth inhibition by 65% and 56% in comparison with the controls in day 19 (p < 0.0001) and day 22 (p < 0.003) respectively (Fig. 5C). To elucidate the molecular mechanism of UMI-77 mediated tumor growth inhibition, western blot and immunohistochemistry on tumor tissue were performed. The western blots of the tumor tissue lysates showed slightly elevated levels of pro-apoptotic proteins, Bax and Bak, and significant decrease of survivin, one of the Inhibitors of Apoptosis Proteins (IAPs) which potently inhibits apoptosis by antagonizing caspase activity (Fig. 5D). The apoptotic cells in tumor tissue were determined by TUNEL-based in situ method and the obtained results showed that positive apoptotic cells of tumor sections were significantly increased in UMI-77-treated BxPC-3 xenograft mice as compared with the control group (Fig. 5E). The toxicity of UMI-77 on normal tissues was examined by H&E analyses (Fig. S9). Histopathology revealed that treatment of mice with UMI-77 did not cause damage to tested tissues from kidney, liver and pancreas, demonstrating that it is not toxic to normal mouse tissues. These findings provide in vivo support of the involvement of Mcl-1 regulated pathway in PC, implicating the potential of Mcl-1 inhibitors as novel antitumor agents for treatment of PC.
