Chemoselectivity of the 1,3-Dipolar Cycloaddition of Some Diazoalkanes with 1,5-Benzodiazepine Derivatives

Regioselective One-Pot Synthesis, Biological Activity and Molecular Docking Studies of Novel Conjugates N-(p-Aryltriazolyl)-1,5-benzodiazepin-2-ones as Potent Antibacterial and Antifungal Agents

Novel 1,2,3-triazolo-linked-1,5-benzodiazepinones were designed and synthesized via a Cu(I)-catalyzed 1,3-dipolar alkyne-azide coupling reaction (CuAAC). The chemical structures of these compounds were confirmed by 1H NMR, 13C NMR, HMBC, HRMS, and elemental analysis. The compounds were screened for their in vitro antibacterial and antifungal activities. Several compounds exhibited good to moderate activities compared to those of established standard drugs. Furthermore, the binding interactions of these active analogs were confirmed through molecular docking.

Design and Synthesis of (3,5-Disubstituted Isoxazole)-Linked [1,5]-Benzodiazepine Conjugates: Evaluation of their Antimicrobial and Anti-Tyrosinase Activities

A series of novel 2-(3,5-disubstituted isoxazolyl)-1,5-benzodiazepines and 2,4-bis-(3,5-disubstituted isoxazolyl)-1,5-benzodiazepine derivatives have been designed and synthesised by employing an alkyne/nitrile oxide cycloaddition ‘click’ type chemistry protocol. The structures of the compounds were determined on the basis of 1H, 13C and 2D-NMR techniques and by HRMS analysis. These hybrid molecules exhibit moderate to significant antimicrobial and anti-tyrosinase activities.
