    摘要:
    Structure-activity relationship studies focused on bio-isosteric replacements of 2-pyridyl resulted in mGlu5 receptor antagonists with reduced inhibition of cytochrome P450 1A2. This led to highly potent, selective and orally bioavailable 2-imidazolyl tetrazoles such as (10) that are devoid of cytochrome P450 inhibitory activity. (C) 2004 Elsevier Ltd. All rights reserved.

  • An Organobase (TBD)-Anchored Mesoporous Silica Nanoparticle-Catalyzed Green Synthesis of Dihydropyrano[2,3-c]pyrazoles

    An efficient, mild, and environmental friendly method has been developed for the synthesis of dihydropyrano[2,3-c]pyrazole in ethanolic water over 1,5,7-triazabicyclo-[4,4,0]-dec-1-ene (TBD)-anchored mesoporous silica nanoparticle catalyst. The method involves the assembly of ethyl acetoacetate, hydrazine hydrate, different aldehydes, and malononitrile. It affords the corresponding product in high yield with short reaction times, while employing a very low loading of catalyst. The catalyst was reused several times without significant loss in activity.

    在 1,5,7- 三氮杂双环-[4,4,0]-癸-1-烯(TBD)锚定介孔二氧化硅纳米粒子催化剂上,开发了一种在乙醇水中合成二氢吡喃并[2,3-c]吡唑的高效、温和且环保的方法。该方法涉及乙酰乙酸乙酯、水合肼、不同的醛和丙二腈的组装。该方法能以较短的反应时间获得高产率的相应产品,同时催化剂的负载量极低。催化剂可重复使用多次,而活性不会明显降低。

    A series of substituted 2,2'-bi-1H-imidazoles and related analogues was synthesized and evaluated for inotropic activity. Structure-activity relationship studies based on a nonclassical bioisosteric approach indicated the necessity of a cyano group on one of the imidazole rings to obtain the desired pharmacological profile. 4(5)-Cyano-2,2'-bi-1H-imidazole (15a) was the most potent inotropic agent in
    合成了一系列取代的2,2'-bi-1H-咪唑和相关类似物,并评估了其正性肌力。基于非经典生物等位线方法的结构活性关系研究表明,咪唑环之一上的氰基必须具有所需的药理特性。4(5)-Cyano-2,2'-bi-1H-咪唑(15a)是该系列中最有效的正性肌力药。在麻醉狗中,0.16 mg / kg iv时左心室dP / dt增加25%(ED25%= 0.16 mg / kg),在1 mg / kg iv时左心室收缩力增加60%。化合物15a是分离自犬心的IV型环状核苷酸磷酸二酯酶的良好抑制剂,具有与氨力农相似的效力。5'-cyano-2,4'-bi-1H-咪唑(44)和4-cyano-2,4' -bi-1H-咪唑(48)具有正性肌力活性。另外,两种可能的1,1'-二甲基氰基-2,2'-bi-1H-咪唑(24和25)是不活泼的,表明酸性NH和氰基对于正性肌力活性至关重要。

Structural investigations reveal that the two isomers are extremely similar with only differences in the methyl group position of the ligands. The iron(II) center is surrounded by three bidentate imidazole Schiff-base ligands in the face-Λ conformation, which affords a distorted [FeN6] octahedral coordination
