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。

New nitronylnitroxide radicals, 2-(4′(5′)-methylimidazol-2′-yl)- and 2-(4′(5′)-trifluoromethylimidazol-2′-yl)-4,4,5,5-tetramethyl-4,5-dihydro-1H-imidazole-1-oxyl 3-oxide, were synthesized. The molecular and crystal structures of the paramagnetic trifluoromethyl derivative were determined. A previously unknown type of hydrogen bonding of imidazol-2-yl-substituted nitronylnitroxides to form ribbons
An antibiotic compound having a novel mechanism of action, weak cytotoxicity, high solubility in water, effective in inhibiting both DNA gyrase GyrB and topoisomerase IV ParE subunits, and having antibacterial activity.
