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-driven photoredox-catalyzed nonaqueous oxidative C-N cleavage of N,N-dibenzylanilines to 2° amides is reported. Further, we have applied this protocol on 2-(dibenzylamino)benzamide to afford quinazolinones with (NH4)2S2O8 as an additive. Mechanistic studies imply that the reaction might undergo in situ generation of α-amino radical to imine by C-N bond cleavage followed by the addition of superoxide ion to form amides.

N-Acyl lactam amides, such as benzoylpyrrolidin-2-one, benzoylpiperidin-2-one, and benzoylazepan-2-one reacted with amines in the presence of DTBP and TBAI to afford the transamidated products in good yields. The reactions were conducted under aqueous conditions and good functional group tolerance was achieved. Both aliphatic and aromatic primary amines displayed good activity under metal-free conditions. A radical reaction pathway is proposed.
