製品説明 | LY294002 (SF 1101, NSC 697286) は人工的に合成した分子としては初めての PI3Kα/δ/β 阻害剤であり、IC50 はそれぞれ 0.5 μM/ 0.57 μM/ 0.97 μM です。溶液中でウォルトマンニン (wortmannin) よりも安定しています。クラス I PI3K および PI3K 関連キナーゼだけでなく、一見 PI3K ファミリーには無関係にある新規のターゲットにも結合します。LY294002 は CK2 阻害剤でもあり、IC50 は 98 nM です。また LY294002 はオートファゴソーム (autophagosome) の形成をブロックする一方で、DNA-PKcs を非特異的に阻害することによりオートファジー (autophagy) を活性化し、アポトーシス (apoptosis) を誘導します。 |

in vitro | LY294002 is not exclusively selective for the PI3Ks, and could in fact act on other lipid kinases and additional apparently unrelated proteins. LY294002 is shown to inhibit not only mTOR and DNA-PK, but also other protein kinases, such as CK2 (casein kinase 2) and Pim-1[5]. LY294002 inactivates Akt/PKB, consequently inhibiting cell proliferation and inducing apoptosis. LY294002 demonstrates a remarkable growth-inhibitory and apoptosis-inducing effect in these colon cancer cell lines, with decreased expression of phosphorylated Akt (Ser473). [2]LY294002 induces marked nuclear pyknosis and diminished cytoplasmic volume in the tumor cells. Thus, LY294002 markedly inhibits ovarian cancer cell proliferation in vitro. LY294002 induces specific G1 arrest in cell growth, leading to almost complete inhibition of melanoma cell proliferation and partial inhibition of MG-63 (osteosarcoma cell line) proliferation. The effect of LY294002 on cell cycle progression may provide insights into a possible link between the PI3K activation pathway and cancer cell cycle regulation. [3] |
in vivo | LY294002 also results in suppression of tumor growth and induction of apoptosis, especially in the LoVo tumors, and therefore shows remarkable effectiveness in the mouse peritonitis carcinomatosa model. [2] LY294002 significantly inhibits growth and ascites formation of ovarian carcinoma. [3] |
キナーゼアッセイ | kinase assays | |
---|---|---|
PI3K inhibition by LY294002 is determined in a radiometric assay using purified, recombinant enzymes with 1 μM ATP. The kinase reaction is carried out for 1 hour at room temperature (24oC) and is terminated by addition of PBS. IC50 values are subsequently determined using a sigmoidal dose–response curve fit (variable slope). CK2 and GSK3β (glycogen synthase kinase 3β) inhibition is established by kinase selectivity screening. LY294002 is tested against the Upstate panel of kinases in 10 μM ATP. | ||

実験の流れ | 1.0×105 cells (100 μL volume/well) are inoculated into 96-well microtiter plates. LY294002 is added to triplicate wells and cultured at 37oC for 0–48 hours. After treatment, 10 μL of Premix WST-1 are added to each microculture well, and the plates are incubated for 60 minutes at 37oC, after which absorbance at 450 nm is measured with a microplate reader. |
