Competitive binding curve of UMI-77 against Mcl-1 is obtained by FP based binding assay using fluorescent labeled Bid BH3 peptide with an IC50 of 1.87±0.22 μM. UMI-77 potently inhibits the cell growth of BxPC-3 and Panc-1 cell lines with IC50 values of 3.4 μM and 4.4 μM respectively, and shows 3 to 5 times less potency in inhibition of the cell growth of two other tested cell lines MiaPaCa-2 (12.5 μM) and AsPC-1 (16.1 μM). The cell growth inhibition potency of UMI-77 correlates with the highest expression of Mcl-1 and Bak, and lowest expression of Bcl-xL in the sensitive cell lines, BxPC-3 and Panc-1. Capan-2 cells are showing similar sensitivity to UMI-77 (IC50 of 5.5 μM) as BxPC-3 and Panc-1, although has low Mcl-1 levels[1].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline

Protocol
Human PC cell lines AsPC-1, BxPC-3 and Capan-2 are cultured in RPMI 1640 medium, while Panc-1 and MiaPaCa are cultured in DMEM medium, all supplemented with 10% fetal bovine serum. The cell growth inhibition after treatment with increasing concentrations of the compounds (e.g., UMI-77; 1,10, and 100 μM) is determined by WST-8 assay[1].

Mice[1]
For BxPC-3 subcutaneous model, 10×106 cells are subcutaneously injected into the flanks of 4-5 week old female severe combined immune deficient mice (ICR-SCID). Palpable tumors start to appear in 3-5 weeks. Tumors are measured twice weekly. To prevent any pain or discomfort, mice are euthanized and their tumors remove once they reach ~1800 mg burden. Tumors are then dissected into 50 mg pieces and re-transplanted into naïve ICR-SCID for serial propagation. Animals are treated with either vehicle or UMI-77 given i.v. (60 mg/kg) on day three post BxPC-3 transplantation for two weeks (5 days a week). Tumor weight is recorded throughout the treatment period. At the end of the treatment period, animals are euthanized and their tumors harvested for protein isolation and western blot analysis for apoptotic markers.
