描述:LY2510924是有效,選擇性的CXCR4拮抗劑;阻止SDF-1結合CXCR4的IC50值為0.079 nM。
靶點:SDF-1α-CXCR4:79.7 pM (IC50);SDF-1α-CXCR4:49.5 pM (Ki)
激酶實驗:LY2510924特異性阻斷SDF-1與CXCR4的結合,IC50值為0.079 nM,并抑制SDF-1誘導的GTP結合,Kb值為0.38 nM。在表達內源性CXCR4的人淋巴瘤U937細胞中,LY2510924抑制SDF-1誘導的細胞遷移,IC50值為0.26nM,并抑制SDF-1 / CXCR4介導的細胞內信號傳導。 LY2510924在腫瘤細胞中表現出對SDF-1刺激的磷酸-ERK和磷酸-Akt的濃度依賴性抑制。生化和細胞分析顯示LY2510924沒有明顯的激動劑活性[1]。 LY2510924主要抑制AML細胞的增殖,幾乎不會誘導細胞死亡,并減少基質細胞保護作用[2]。
動物實驗:
小鼠:SCID雌性小鼠靜脈內注射MDA-MB-231細胞,并用載體(1×PBS)或3mg / kg配制在1×PBS中的LY2510924皮下處理。***組和第2組動物每天兩次接受載體或3mg / kg LY2510924,持續數天,在腫瘤細胞注射***天開始***。第3組動物每天兩次接受3mg / kg LY2510924 15,持續13天,在腫瘤細胞注射后一天開始***。***后,肺組織在10%中性緩沖福爾馬林中固定至少24小時,肺葉存在于組織切片[1]。
