產(chǎn)品描述: | Epacadostat (INCB024360)是一種有效的選擇性吲哚胺 2,3-雙加氧酶(IDO1)抑制劑,IC50為 10 nM。它對(duì)IDO1的選擇性高于其他相關(guān)酶如IDO2或TDO |
靶點(diǎn): |
IDO1(immune cells):10 nM;IDO;Indoleamine2,3-Dioxygenase(IDO) |
體外研究: |
在IFN-γ-處理的人HeLa細(xì)胞中,INCB024360有效抑制犬尿素產(chǎn)生。INCB024360也會(huì)促進(jìn)T和自然殺傷(NK)細(xì)胞的生長(zhǎng),增加IFN-γ產(chǎn)生,并減少轉(zhuǎn)化為調(diào)節(jié)性T (T(reg))-樣細(xì)胞 |
體內(nèi)研究: |
INCB024360 (100 mg/kg, p.o.),通過(guò)IDO1抑制,在免疫活性小鼠中抑制kyn產(chǎn)生和腫瘤生長(zhǎng),但是在免疫缺陷小鼠中無(wú)效。 在負(fù)荷CT26結(jié)腸癌的小鼠中,INCB024360 (100 mg/kg, p.o.)通過(guò)減少犬尿素也會(huì)抑制表達(dá)IDO腫瘤的生長(zhǎng) |
細(xì)胞實(shí)驗(yàn): |
Cell lines: Jurkat cells Concentrations: 50 μM Incubation Time: 72 h Method: Jurkat cells were incubated with serially diluted epacadostat for 72 h. Their viability was measured and analyzed as percentage of the non-treated control. |
動(dòng)物實(shí)驗(yàn): |
Animal Models: 負(fù)荷PAN02胰腺腫瘤的雌性C57BL/6或Balb/c nu/nu小鼠 Dosages: ~100 mg/kg,一天兩次 Administration: p.o. |
