體外研究
(In Vitro)

UMI-77 對 Mcl-1 的競爭性結(jié)合曲線是通過基于 FP 的結(jié)合測定使用熒光標記的 Bid BH3 肽獲得的,IC50 為 1.87±0.22 μM。UMI-77 有效抑制 BxPC-3 和 Panc-1 細胞系的細胞生長,IC50 值分別為 3.4 μM 和 4.4 μM,抑制細胞的效力降低 3 到 5 倍其他兩種測試細胞系 MiaPaCa-2 (12.5 μM) 和 AsPC-1 (16.1 μM) 的生長。UMI-77 的細胞生長抑制效力與敏感細胞系 BxPC-3 和 Panc-1 中 Mcl-1Bak 的最高表達以及 Bcl-xL 的最低表達相關(guān)。Capan-2 細胞對 UMI-77 表現(xiàn)出與 BxPC-3 和 Panc-1 相似的敏感性 (IC50 為 5.5 μM),盡管 Mcl-1 水平較低[1]

體內(nèi)研究
(In Vivo)

UMI-77 表現(xiàn)出適度的代謝穩(wěn)定性,半衰期為 45 分鐘。確定了 SCID 小鼠中 UMI-77 的最大耐受劑量 (MTD)。每周連續(xù) 5 天靜脈內(nèi)給藥 60 mg/kg,持續(xù)兩周不會導致動物體重減輕,并且在處理過程中沒有明顯的毒性跡象。將劑量增加到 80 mg/kg 顯示嚴重的動物體重減輕 (>20%),因此 60 mg/kg 用作體內(nèi)功效研究的抑制劑量。與對照組相比,在第 19 天 (p<0.0001) 和第 22 天 (p<0.003),每周連續(xù) 5 天每天使用 UMI-77 處理兩周,與對照組相比,腫瘤生長抑制具有統(tǒng)計學意義,分別為 65% 和 56%[1]。

Cell Assay
[1]

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].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Administration
[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 na?ve 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.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
