(1,3-Benzothiazol-2-yl) amino-9-(10H)-acridinone derivatives were synthesized via a procedure based on the Ullman reaction and were assessed for their in vitro antileishmanial and anti-HIV activities. Two derivatives, 4-(6-nitro-benzothiazol-2-ylamino)-10H-acridin-9-one and 1-(6-amino-benzothiazol-2-ylamino)-10H-acridin-9-one, revealed a selective antileishmanial activity, mainly due to amastigote-specific toxicity. Results suggested that:the addition of a benzothiazole group on a parent amino-9-(l OH)-acridinone ring could enhance antileishmanial abilities,the presence of a 6-amino-benzothiazole group on position 2 amino chain or a 6-nitro-benzothiazole group on position 4 amino chain was essential for specific anti-amastigote properties.

通过基于Ullman反应的程序,合成了(1,3-苯并噻二唑-2-基)氨基-9-(10H)-吖啶酮衍生物,并评估了其体外抗锥虫和抗HIV活性。两种衍生物,即4-(6-硝基-苯并噻二唑-2-基氨基)-10H-吖啶-9-酮和1-(6-氨基-苯并噻二唑-2-基氨基)-10H-吖啶-9-酮,表现出选择性抗锥虫活性,主要是由于其对阿米巴特异阶段的毒性。结果表明:在母体氨基-9-(10H)-吖啶酮环上添加苯并噻二唑基团可以增强抗锥虫能力,而在位置2上的氨基链携带6-氨基-苯并噻二唑基团或在位置4上的氨基链携带6-硝基-苯并噻二唑基团对于特定的抗阿米巴活性至关重要。(C) 2004 Elsevier SAS. 保留所有权利。
