三环化学结构是许多针对所有神经递质通路的重要药物的核心。这些药物使有效疗法能够治疗从消化性溃疡病到精神疾病。然而,当全身给药时,它们会引起严重的副作用,限制了它们的使用。为了使用光获得局部和按需药理作用,我们设计了基于偶氮苯的光异构配体,模拟三环化学结构并显示可逆控制的活性。的伪类似物三环拮抗剂哌仑西平表明这是毒蕈碱型乙酰胆碱受体的有效策略,示出两个照射时更强的抑制在体外和在心脏心房离体. 尽管应用化学修饰使哌仑西平衍生物对光刺激敏感,但该组中最有效的候选者隐西平-2保持了中等但有希望的 M 1与 M 2亚型选择性。这些三环类药物的光开关“隐性唑啉”可能开辟一条通用途径,在时空上靶向其治疗作用,同时降低其全身毒性和不良反应。

compound 4l in mice for its pharmacological profile proved it as safer anticonvulsant, devoid of the side effects such as motor dysfunction and hepatotoxicity of classical antiepileptic drugs (ED50 = 26.1 mg/kg, MES, mice, i.p.; ED50 = 79.4 mg/kg, scPTZ, mice, i.p.; TD50 = 361.2 mg/kg, mice, i.p.). We also predicted physiochemical and pharmacokinetic properties of structurally optimized quinazolin‐4(3H)‐ones
prognosis. Thus, inhibiting CDC25 activity in cancer treatment appears a good therapeutic strategy. In this article, refinement of the initial hit XDW-1 by synthesis and screening of a focused compound library led to the identification of a novel set of imidazopyridine derivatives as potent CDC25 inhibitors. Among them, the most potent molecule was CHEQ-2, which could efficiently inhibit the activities

new condensed benzimidazole derivatives – 5H,12H-benzo[4,5]imidazo[1,2-a]pyrrolo[1,2-d]pyrazines, based on furan ringtransformation in 1-[(5-alkylfuran-2-yl)methyl]-2-(chloromethyl)benzimidazoles. Two routes are presented for the formation of pyrrolopyrazine system, with different order of steps for the introduction of amino group and opening of the furan ring.
