PHA-680632
CAS No. : 398493-79-3
MCE 国际站:PHA-680632
产品活性:PHA-680632是极光激酶抑制剂 (aurora),对aurora A,B和C的 IC50 值分别为27,135和120 nM。
研究领域:Cell Cycle/DNA Damage | Epigenetics
作用靶点:Aurora Kinase
In Vitro: PHA-680632 shows 30- to 200-fold higher IC50s of FLT3, LCK, PLK1, STLK2, VEGFR2, and VEGFR3 compared with Aurora A. PHA-680632 has potent antiproliferative activity in a wide range of cell types. The IC50s are 0.32, 0.41, 0.06, 1.17, 0.56, 0.62, 0.29, 0.11, 1.56, 0.62, 0.07, 0.13, 0.41 μM for C33A, HeLa, HCT116, HT29, LOVO, A549, MCF7, A2780, U2OS, DU145, U937, HL60, NHDF. PHA-680632 can cause polyploidy in tumor cells. PHA-680632 cell treatment induces phenotypes similar to Aurora A or B depletion. PHA680632, inhibits colony formation in different cancer cell lines and induced polyploidy. Aurora-A inhibition by PHA680632 enhances radiation response in cancer cells, especially in p53-deficient cells.
In Vivo: PHA-680632 suppresses tumor growth in animal models. PHA-680632 treatment at 45 mg/kg dose results in 85% of TGI without signs of toxicity in the HL60 human acute myelogenous leukemia xenograft model. PHA-680632 treatment at 60 mg/kg i.v. b.i.d. for 5 days results in 78% of TGI without signs of toxicity in the A2780 human ovarian carcinoma model. PHA680632 in association with radiation leads to an additive effect in cancer cells, especially in the p53-deficient cells, but does not act as a radiosensitiser.

文献和实验(1)原理:T淋巴细胞与有丝分裂原在体外共同培养时,受到后者的刺激可发生形态学和生物化学的变化,部分小淋巴细胞转化为不成熟的母细胞,并进行有丝分裂,这种方法称为淋巴细胞转化试验(lymphocyte transformation test)。 (2)试剂:①1640培养液:广州威佳科技,临用前加入20%犊牛血清(灭活),青链霉素各100IU/ml,用5.6%NaHCO3(经高压灭菌)校正pH7.2~7.4,是为应用培养液。 ②PHA溶液:上海伊华医学科技有限公司,批号:20040301
关键词: 淋巴细胞 转化实验 乙型肝炎 细胞 免疫 细胞 免疫对致病或清除HBV均有重要意义,其中以T淋巴细胞 对HBsAg的敏感性最为重要。我们利用高纯化的HBsAg和PHA(植物血凝素)为刺激因子,对我院住院的107例HBsAg阳性的乙肝患者外周血淋巴细胞 ,采用3H-TdR 病毒研究中心掺入法,进行特异性和非特异性淋巴细胞 转化实验,以探讨乙肝患者的细胞 免疫状态及其临床价值。 107例患者均排除其他肝炎病毒混合感染。其中,男
率高达90.43%,而正常胃粘膜基本是阴性,故认为PHA是胃癌的诊断性标志。BSA对乳腺恶性肿瘤阳性率达79%,而对良 性病 变均呈阴性反应,提示BSA可能为乳腺恶性肿瘤的相关标志。凝集素还有助于判别肿瘤的组织类型,如神经系统星形细胞瘤ConA阳性,小胶质细胞瘤阴性,肾腺癌UEA1阴性,透明细胞癌阳性。 三、凝集素在免疫细胞化学中的应用 凝集素可为荧光素、酶和生物素等所标记,分别进行下列染色法: 1.直接法 标记物直接标记在凝集
