具有药理活性的苯并[ b ]噻吩衍生物。第六部分 N -2-氯乙基-N-乙基-3-氨基甲基苯并[ b ]噻吩盐酸盐的4-和6-卤代衍生物
摘要:
(环化米热多磷酸-chlorophenylthio)丙酮,得到的混合物中4-氯和6-氯-3-甲基苯并[ b ]噻吩(7:4),和(米-bromophenylthio)丙酮4:1的混合物-溴和6-溴-3-甲基苯并[ b ]噻吩(1:3)。这些产物通过4-和6-氯-3-甲基苯并[ b ]噻吩和4-溴-3-甲基苯并[ b ]噻吩的明确合成来鉴定。N取代溴代3-甲基苯并[ b ]噻吩在沸腾的四氯化碳中的-溴代琥珀酰亚胺得到相应的溴甲基化合物,该化合物容易与2-乙基氨基乙醇在沸腾的苯中反应。所得的氨基醇与亚硫酰氯在干沸腾的氯仿中反应,得到所需的(2-氯乙基)胺。

Identification of 4,5-Dihydro-1<i>H</i>-pyrazolo[4,3-<i>h</i>]quinazoline Derivatives as a New Class of Orally and Selective Polo-Like Kinase 1 Inhibitors
Polo-like kinase 1 (Plk1) is a fundamental regulator of mitotic progression whose overexpression is often associated with oncogenesis and therefore is recognized as an attractive therapeutic target in the treatment of proliferative diseases. Here we discuss the structure-activity relationship of the 4,5-dihydro-1H-pyrazolo[4,3-h]quinazoline class of compounds that emerged from a high throughput screening (HTS) campaign as potent inhibitors of Plk1 kinase. Furthermore, we describe the discovery of 49, 8-[2-methoxy-5-(4-methylpiperazin-1-yl)phenyl]amino}-1-methyl-4,5-dihydro-1H-pyrazolo-[4,3-h]quinazoline-3-carboxamide, as a highly potent and specific ATP mimetic inhibitor of Plk1 (IC(50) = 0.007 mu M) as well as its crystal structure in complex with the methylated Plk1(36-345) construct. Compound 49 was active in cell proliferation against different tumor cell lines with 1050 values in the submicromolar range and active in vivo in the HCT116 xenograft model where it showed 82% tumor growth inhibition after repeated oral administration.
