    3-乙氧基亚甲基-2,4-二氧戊酸乙酯和乙氧基亚甲基草酰乙酸乙酯与3-氨基吡唑类似物的反应。3,6,7-三取代吡唑并[1,5- a ]嘧啶衍生物的合成与化学反应†
    摘要:
    一系列3-取代的6-乙酰基-7-碳乙氧基吡唑并[1,5- a ]嘧啶(6a,b,c)和3-取代的6,7-二碳乙氧基吡唑并[1,5- a ]的化学反应性通过3-氨基吡唑类似物(3a,b,c)与3-乙氧基亚甲基-2,4-二氧戊酸乙酯(1)或3-乙氧基亚甲基草酰乙酸乙酯(2)的缩合反应制得嘧啶(7a,b,c)。调查。6或7的催化加氢得到4,7-二氢衍生物(8或9)。用乙酸和水处理6a,b进行环转化为6H-吡唑并[1,5- a ] [1,3]二氮杂-6-6(17a,b)。通过用6型苯肼化合物处理,进行环化以产生2个H-二吡唑并[1,5- a:4',3'- e ]嘧啶(18a,b,c)。在室温下用过量的重氮甲烷处理化合物6或7,以优异的产率得到5-甲基-6 H-环丙基[5a,6a]吡唑并-[1,5- a ]嘧啶(24和25)。但是,当该反应在冰冷却下进行时,仅23型化合物被隔离了。还描述了6a与重氮乙酸乙酯的反应。

    Synthesis and Pharmacological Activity of Triazole Derivatives Inhibiting Eosinophilia
    摘要:
    In order to develop novel antiasthmatic agents based on a new mechanism of action, a series of 3-substituted 5-amino-1-[(methylamino)(thiocarbonyl)]-1H-1,2,4-triazole derivatives were synthesized and evaluated in a model in which eosinophilia was induced in the ah-way through intravenous (iv) injection of Sephadex particles on days 0, 2, and 5. After screening of several hundred derivatives, we finally identified the highly potent eosinophilia inhibitor 5-amino-3-(4-chlorophenyl)-1-[(methylamino)(thiocarbonyl)]-1H-triazole (23c, GCC-AP0341), which had ID50 values of 0.3 and 0.07 mg/kg when administered orally (os) and intraperitoneally tip), respectively. This compound showed complete inhibition of the hypersensitivity induced by ascaris inhalation at an ip dose of 1 mg/kg as well as low toxicity, with an LD(50) value of > 2.0 g/kg in mice. Extensive study of its mechanism of action revealed that 23c inhibited eosinophil survival induced by interleukin-5 (IL-5), but had little or no effect on leukotriene D-4 (LTD(4)) or platelet-activating factor (PAF)-induced responses. Taken together, these results suggest 23e as a novel candidate for the treatment of chronic asthma. Further studies are now underway.

    The synthesis and in vitro cytotoxic characteristics of new imidazo[1,2‐b]pyrazole‐7‐carboxamides were investigated. Following a hit‐to‐lead optimization exploiting 2D and 3D cultures of MCF‐7 human breast, 4T1 mammary gland, and HL‐60 human promyelocytic leukemia cancer cell lines, a 67‐membered library was constructed and the structure–activity relationship (SAR) was determined.
