  Antitumor Benzothiazoles. 26. 2-(3,4-Dimethoxyphenyl)-5-fluorobenzothiazole (GW 610, NSC 721648), a Simple Fluorinated 2-Arylbenzothiazole, Shows Potent and Selective Inhibitory Activity against Lung, Colon, and Breast Cancer Cell Lines

  摘要：

  A series of new 2-phenylbenzothiazoles has been synthesized on the basis of the discovery of the potent and selective in vitro antitumor properties of 2-(3,4-dimethoxyphenyl)-5-fluorobenzothiazole (8n; GW 610. NSC 721648). Synthesis of analogues substituted in the benzothiazole ring was achieved via the reaction of o-aminothiophenol disulfides with substituted benzaldehydes under reducing conditions. Compounds were evaluated in vitro in four human cancer cell lines, and compound 8n was found to possess exquisitely potent antiproliferative activity (GI(50) < 0.1 nM for MCF-7 and MDA 468). Potent and selective activity was also observed in the NCI 60 human cancer cell line panel. Structure-activity relationships established that the compound 8n stands on a pinnacle of potent activity, with most structural variations having a deactivating in vitro effect. Mechanistically, this new series of agents contrasts with the previously reported 2-(4-aminophenyl)benzothiazoles; compound 8n is not reliant on induction of CYP1A1 expression for antitumor activity.

  Dibenzothiazepine analogues containing lactam, amidine and imine moieties were prepared from 2-aminophenyl disulfides via one-pot S-arylation. The S-arylation involved cleavage of an S-S bond of disulfides and SNAr reaction in aqueous ammonia solution of L-cysteine to afford diaryl sulfides. Dibenzothiazepine analogues having lactam and amidine moieties were obtained by cyclization of the corresponding

  focus on their unsubstituted ring counterparts. Here we describe a new concise and efficient synthetic route to biologically relevant 2-phenylbenzothiazoles in high yield from the reaction of substituted 2-aminothiophenol disulfides and benzaldehydes, promoted by the inexpensive and non-toxic inorganic oxidant sodium metabisulfite in DMSO at 120 °C. Our new method is tolerant of a range of substituents

  某些在苯并噻唑环上含有取代基的2-苯基苯并噻唑具有重要的生物学特性，但是迄今为止描述的2-苯基苯并噻唑的大多数合成方法都集中在它们的未取代环对应物上。在这里，我们描述了一种新的简洁有效的合成路线，该路线是由廉价的且无毒的无机氧化剂偏亚硫酸氢钠在DMSO中于120°C促进的，是由取代的2-氨基硫代苯酚二硫化物与苯甲醛的反应以高收率获得生物相关的2-苯基苯并噻唑的新方法。我们的新方法可耐受苯并噻唑和苯环上的一系列取代基，并且无需柱色谱即可有效获得取代的2-苯基苯并噻唑。

  New fluorinated 2-aryl-benzothiazoles, -benzoxazoles, and -chromen-4-ones have been synthesized and their activity against MCF-7 and MDA 468 breast cancer cell lines compared with the potent antitumor benzothiazole 5. Analogues such as 9a, b and 12a, d yielded submicromolar GI50 values in both cell lines; however, none of the new compounds approached 5 in terms of antitumor potency. For 5, binding

  已经合成了新的氟化的2-芳基-苯并噻唑，-苯并恶唑和-铬-4-酮，与有效的抗肿瘤苯并噻唑5相比，它们对MCF-7和MDA 468乳腺癌细胞系具有活性。 12a，d在两种细胞系中产生亚微摩尔GI 50值；然而，就抗肿瘤效力而言，新化合物均未达到5。对于5，似乎必须结合芳基烃受体，但不足以抑制生长。
