  Antitumour benzothiazoles. Part 20: 3′-Cyano and 3′-Alkynyl-Substituted 2-(4′-Aminophenyl)benzothiazoles as new potent and selective analogues

  摘要：

  The synthesis of a new series of antitumour 2-(4-aminophenyl)benzothiazole analogues, substituted in the 3'-position by cyano or alkynyl groups, is described. Several of the analogues, notably the 5-fluorinated compounds 7c and 9c, were found to possess potent in vitro activity against MCF-7 and MDA 468 human cancer cell lines. More comprehensive in vitro analysis (NCI 60-cell line) established compound 7c as a particularly potent and selective 2-(4-aminophenyl)benzothiazole analogue. (C) 2002 Elsevier Science Ltd.

  Antitumor Benzothiazoles. 14. Synthesis and in Vitro Biological Properties of Fluorinated 2-(4-Aminophenyl)benzothiazoles

  摘要：

  Synthetic routes to a series of mono- and difluorinated 2-(4-amino-3-substituted-phenyl)benzothiazoles have been devised. Whereas mixtures of regioisomeric 5- and 7-fluorobenzothiazoles were formed from the established Jacobsen cyclization of precursor 3-fluorothiobenzanilides, two modifications to this general process have allowed the synthesis of pure samples of these target compounds. Fluorinated 2-(4-aminophenyl)benzothiazoles were potently cytotoxic (GI(50) < 1 nM) in vitro in sensitive human breast MCF-7 (ER+) and MDA 468 (ER-) cell lines but inactive (GI(50) > 10 muM) against PC 3 prostate, nonmalignant HBL 100 breast, and HCT 116 colon cells. The biphasic dose-response relationship characteristically shown by the benzothiazole series against sensitive cell lines was exhibited by the 4- and 6-fluorobenzothiazoles (10b,d) but not by the 5- and 7-fluoro-benzothiazoles (10h,i). The most potent broad spectrum agent in the NCI cell panel was 2-(4-amino-3-methylphenyl)-5-fluorobenzothiazole (10h) which, unlike the g-fluoro isomer (10d), produces no exportable metabolites in the presence of sensitive MCF-7 cells. Induction of cytochrome P450 CYP1A1, a crucial event in determining the antitumor specificity of this series of benzothiazoles, was not compromised. 10h is currently the focus of pharmaceutical and preclinical development.

  Substituted 2-phenylbenzazole compounds of formula (I) wherein X represents S or O and Q represents a direct bond, -CH2- or -CH=CH-, exhibit selective antiproliferative activity in respect of mammalian tumour cells. At least in preferred embodiments the benzene ring of the benzazole nucleus has a halogen substituent, preferably fluorine, and the 2-phenyl group has a 4'-amino substituent which may be conjugated with an amino acid to provide a water soluble amino acid amide prodrug or salt thereof.

  公式（I）中的2-苯基苯并咪唑化合物，其中X代表S或O，Q代表直接键，-CH2-或-CH=CH-，在哺乳动物肿瘤细胞中表现出选择性抗增殖活性。在至少优选实施例中，苯并咪唑核的苯环具有卤素取代基，优选为氟，而2-苯基基团具有4'-氨基取代基，可以与氨基酸结合以提供水溶性氨基酸酰胺前药或其盐。
