  Antitumor Benzothiazoles. 3. Synthesis of 2-(4-Aminophenyl)benzothiazoles and Evaluation of Their Activities against Breast Cancer Cell Lines in Vitro and in Vivo

  摘要：

  A new series of 2-(4-aminophenyl)benzothiazoles substituted in the phenyl ring and benzothiazole moiety has been synthesized by simple, high-yielding routes. The parent molecule 5a shows potent inhibitory activity in vitro in the nanomolar range against a panel of human breast cancer cell lines, but is inactive (IC50 > 30 mu M) against other cell types: activity against the sensitive breast lines MCF-7 and MDA 468 is characterized by a biphasic dose-response relationship. Structure-activity relationships derived using these cell types has revealed that activity follows the heterocyclic sequence benzothiazole > benzoxazole much greater than benzimidazole and that 2-(4-aminophenyl)benzothiazoles bearing a 3'-methyl- 9a, 3'-bromo- 9c, 3'- iodo- 9f, and 3'-chloro-substituent 9i are especially potent and their activity extends to ovarian, lung, and renal cell lines. Four compounds have been evaluated in vivo against human mammary carcinoma models in nude mice. Compound 9a showed the most potent growth inhibition against the ER(+) (MCF-7 and BO) and ER(-) (MT-1 and MT-3) tumors. Our efforts to identify a pharmacological mechanism of action for these intriguing compounds have not, as yet, been successful.

  There are disclosed herein 2-phenylbenzazole compounds having a 3'-substituent and a 4'-NR.sup.2 R.sup.6 substituent in the phenyl group where R.sup.5 and R.sup.6 are each hydrogen or alkyl, or where the $'-NR.sup.5 R.sup.6 substituent is N-acyl (or N-benzoyl). There are also disclosed 2-phenylbenzazole compounds in the form of 4'-N sulphamate salts. Such compounds exhibit significant selective cytotoxic activity in respect of tumor cells and provide potentially useful chemotherapeutic agents for selective treatment of a range of cancers.

  本文披露了含有3'-取代基和4'-NR.sup.2 R.sup.6取代基的2-苯基苯并咪唑化合物，其中苯基中的R.sup.5和R.sup.6分别为氢或烷基，或者4'-NR.sup.5 R.sup.6取代基为N-酰基（或N-苯甲酰基）。还披露了以4'-N磺酸盐形式存在的2-苯基苯并咪唑化合物。这些化合物在肿瘤细胞中表现出显著的选择性细胞毒活性，并为选择性治疗多种癌症提供了潜在有用的化疗药物。
