  摘要：

  在嘌呤，蝶啶，[1,2,5]-噻二唑并[3,4-d]嘧啶和喹唑啉环系统中制备了一系列己酮可可碱代谢物的类似物，并评估了它们抑制肿瘤坏死因子产生的能力。细菌脂多糖（LPS）刺激的人外周血单核细胞中的α-α（TNFα）。还测试了更具活性的化合物对人嗜中性白细胞对环状AMP磷酸二酯酶IV型（PDE IV）的抑制作用，以帮助确定其作用机理。在小鼠体内LPS诱导的白细胞减少症模型中评估了在体外TNFα测定中显示出良好活性的所选化合物。TNFα分析中最有效的化合物6、31和58，每种抑制TNFα的产生，IC50约为5 microM。化合物58是一种非常差的PDE IV抑制剂，但在预防小鼠中由TNFα诱导的白细胞减少症中活性最高，在50 mg / kg剂量下可提供60％以上的保护作用。因此，诸如58的化合物，它们是TNFα产生的良好抑制剂，但没有PDE IV抑制特性，可能具有作为新的抗炎剂的潜力。

  Diuretic activities of xanthine or nonxanthine adenosine antagonists and their ameliorative effects against glycerol-induced acute renal failure in rats were investigated in order to clarify the physiological and pathological function of adenosine receptors in the kidney. Diuretic and natriuretic activities of a variety of adenosine antagonists clarified systematically for the first time that the blockade

  为了阐明肾脏中腺苷受体的生理和病理功能，研究了黄嘌呤或非黄嘌呤腺苷拮抗剂的利尿作用及其对甘油诱导的急性肾衰竭的缓解作用。各种腺苷拮抗剂的利尿和利尿作用首次系统性地阐明，在钠和水的排泄中，A1受体的阻滞比A2受体的阻滞更重要，并支持内源性肾内腺苷水平直接增强肾小管钠吸收的假说。 。急性肾衰竭中8取代的黄嘌呤的构效关系研究表明，腺苷A1受体的激活是发展这种肾衰竭的重要因素。一系列8-（3-去甲金刚烷基）黄嘌呤表现出极强的利尿和利尿活性（24; 2.5微克/千克，po，治疗大鼠尿排泄值与对照大鼠尿排泄值之比= 1.69，该比率（治疗大鼠的Na + / K +相对于对照组大鼠的Na + / K + ＝ 1.76）和抗甘油诱导的急性肾衰竭的有效改善作用（24; 10微克/ kg，腹腔注射，抑制55％）。通过对结构-活性关系的详细研究，我们可以推测，肾脏和大脑之间可能存在腺苷A1受体的一些组织差异，并
