描述:

OSI027是一种选择性的有效的双重mTORC1和mTORC2抑制剂,无细胞试验中IC50分别为22 nM 和 65 nM,作用于mTOR的选择性比作用于PI3Kα,PI3Kβ,PI3Kγ或 DNA-PK高100多倍。

溶解性:DMSO Solubility: 18 mg/mL (44.28 mM)

体外研究:

OSI-027 shows the selective and ATP competitive inhibition activities against mTORC1 and mTORC2 with IC50 of 22 nM and 65 nM, respectively. In addition, OSI-027 inhibits mTOR signaling of phospho-4E-BP1 with an IC50 of 1 μM in cell-based assays. OSI-027 exhibits anti-proliferative activities against several acute leukemia cell lines of myeloid/megakaryocytic origin in a dose-dependent manner, including U937, KG-1, KBM-3B, ML-1, HL-60, and MEG-01 cells. A recent study shows that inhibition of mTORC1/2 by OSI-027 effectively suppresses phosphorylation of Akt (S473) and cell proliferation in breast cancer cells.

体内研究:In GEO colorectal xenograft, OSI-027 (65 mg/kg) inhibits both mTORC1 and mTORC2 effectors, including 4E-BP1, Akt, and S6 phosphorylation. Furthermore, mTORC1 and mTORC2 inhibition together by OSI-027 potently inhibits tumor growth more than mTORC1 inhibition by rapamycin.
