體外研究 | GSK1838705A有效且ATP競爭性抑制IGF-1R和IR,appKi值分別為0.7 nM和1.1 nM。在細(xì)胞中,GSK1838705A有效抑制配體誘導(dǎo)的IGF-1R和IR磷酸化,IC50 分別為85 nM 和79 nM。GSK1838705A對一系列衍生自固體和血液腫瘤的細(xì)胞系,比如L-82,SUP-M2,SK-ES 和MCF-7細(xì)胞表現(xiàn)出顯著的抗增殖作用,EC50 分別為24 nM,28 nM,141 nM 和203 nM。GSK1838705A使MCF-7 和NCl-H929細(xì)胞主要積累在細(xì)胞周期的G1 (2N)期。GSK1838705A也會抑制ALK,Ki為0.35 nM,抑制核仁磷酸蛋白(NPM)-ALK融合細(xì)胞的增殖,EC50為24-88 nM。GSK1838705A有效抑制Karpas-299 和SR-786細(xì)胞中NPM-ALK磷酸化,而對STAT3磷酸化僅有適度的作用。[1] | ||||||
體內(nèi)研究 | 在負(fù)荷NIH-3T3/LISN腫瘤的小鼠體內(nèi),GSK1838705A (60 mg/kg)口服治療抑制77%腫瘤生長,而沒有顯著的體重?fù)p失。在負(fù)荷COLO 205腫瘤的小鼠體內(nèi),GSK1838705A (30 mg/kg)能夠抑制80%的腫瘤生長。此外,GSK1838705A的抗腫瘤作用在負(fù)荷HT29異種移植物或BxPC3異種移植物的小鼠體內(nèi)也能觀察到。在小鼠體內(nèi),GSK1838705A (60 mg/kg)通過抑制IR信號,引起血糖水平短暫增加2倍。GSK1838705A (60 mg/kg)抑制已建立的Karpas-299異種移植物的生長,抑制率為93%,而對大鼠的體重沒有影響。[1] | ||||||

GSK1838705A suppresses glioma tumor growth and induces apoptosis in vivo. (A) Following inoculation of U87MG cells, formulated vehicle control or GSK1838705A (4 and 8 mg/kg) was injected into the corresponding group of nude mice (n=6/group) once daily. The tumors were measured every other day for 11 days and the tumor volumes were calculated. Starting on day 7, the differences between the treatment groups (4 and 8 mg/kg) and the vehicle control group were significant (P<0.05). (B) Body weights of the mice during the course of treatment were measured as an indication of significant cytotoxic effects. The data are expressed as the mean ± standard deviation. No significant differences are observed between any two of the groups during the course of treatment. (C) At the end of treatment, the tumors were harvested. GSK1838705A (8 mg/kg) induced the apoptosis of tumor cells in vivo, determined using a TUNEL assay (green) and nuclear staining with Hoechst (blue). Representative images are shown (magnification, ×40). TUNEL, terminal deoxynucleotidyl transferase dUTP nick end labeling.
