On October 31, 1991, Kaczmarek, Lukasz; Nantka-Namirski, Pawel; Klodzinska, Aleksandra; Bujak, Barbara; Tatarczynska, Ewa published an article.Name: [2,2′-Bipyridine]-3,3′-diamine The title of the article was Synthesis and pharmacological properties of some dipyrido[1,3]diazepinones. And the article contained the following:
The synthesis of two isomeric dipyrido[1,3]diazepinones (I and II, R = e.g., Bu, 3-dimethylaminopropyl) and N-monosubstituted derivatives of I by cyclocondensation of corresponding bipyridinediamines with urea was described. The alkylation of these compounds with alkyl halides in K2CO3/DMF/TBAB system gave N,N’-disubstituted compounds Dipyrido[1,3]diazepinones and I showed a weak general depressive action on the central nervous system and they were also devoid of antidepressant, anxiolytic, anticonvulsant and serotoninolytic or serotoninomimetic properties. The experimental process involved the reaction of [2,2′-Bipyridine]-3,3′-diamine(cas: 75449-26-2).Name: [2,2′-Bipyridine]-3,3′-diamine
The Article related to dipyridodiazepinone pharmacol preparation, Pharmacology: Structure-Activity and other aspects.Name: [2,2′-Bipyridine]-3,3′-diamine
