The new MMP-9 inhibitor 1-{4-[(4-chlorobenzoyl)amino]phenyl}sulfonyl-L-proline, with a theoretical inhibition constant of IC50 = 4 × 105 M, was constructed on the basis of structural requirements for selective inhibitors of gelatinases. This constructed compound and its close structural analogs were synthesized and these substances were found to have low toxicity, (LD50 > 300 mg/kg). The new inhibitor given p.o. at a dose of 20 mg/kg/day on the background of acute myocardial infarction significantly decreased the content of immunoreactive MMP-9 in plasma in rats, to the level obtained with doxycycline.

A visible-light-promoted and simple iron salt-catalyzed N-arylation was achieved efficiently under external photosensitizer-free conditions. Arylboronic acids and bench-stable dioxazolones were used for this cross-coupling reaction. This reaction features high reactivity, wide substrate scope, good functional group tolerance, simple operation procedure, and mild reaction conditions. Preliminary mechanistic investigations were conducted to support a radical pathway. This method may contribute to shift the paradigm of iron-catalyzed C-N bond construction and nitrene transfer chemistry.

, (2021/08/18)
A new approach for amide bond formation via a mild and efficient Iron-catalyzed cross-coupling reaction of acylhydrazines and amines using TBHP as oxidant is described. This protocol is compatible with a wide range of amines and acylhydrazines. In addition, the synthetic application of the reaction is presented.
