当前尚无可用于治疗由肠病毒(EV)引起的急性和慢性疾病的药物,例如普通感冒,脑膜炎,脑炎,肺炎和心肌炎,伴或不伴连续性扩张性心肌病。在这里,我们报告吡唑并嘧啶的发现和表征,吡唑并嘧啶是一类耐受性强且有效的新型EV抑制剂。化合物抑制EV的体外广谱与IC的复制50值之间的0.04和0.64μ中号适用于对pleconaril(一种已知的衣壳结合抑制剂)有抗性的病毒,而不会影响细胞色素P450酶的活性。使用病毒学和遗传学方法,病毒衣壳被确定为最有希望的,口服生物利用的化合物3-(4-三氟甲基苯基)氨基-6-苯基吡唑并[3,4- d ]嘧啶-4-胺(OBR-5 )的靶标-340)。柯萨奇病毒B3引起的小鼠慢性心肌炎的预防性和治疗性应用都得到了证明。小鼠体内良好的药代动力学,毒理学和药效学特征使OBR-5340成为高度有前途的候选药物,并且正在进行非临床监管计划。

A concise construction of 12H-benzo[4,5]thiazolo[2,3-b]quinazolin-12-ones via an unusual TBHP/Na<sub>2</sub>CO<sub>3</sub> promoted cascade oxidative cyclization and interrupted Dimroth rearrangement
An interrupted Dimroth rearrangement was merged into the oxidative cyclization between isatins and 2-haloaryl isothiocyanates, giving 12H-benzo[4,5]thiazolo[2,3-b]quinazolin-12-one derivatives.
This invention relates to novel compounds of Formula (I), and compositions thereof, useful in the treatment of disease states mediated by the chemokine, Interleukin-8 (IL-8).
