  1,2,4‐Triazole‐3‐Thione Analogues with a 2‐Ethylbenzoic Acid at Position 4 as VIM‐type Metallo‐β‐Lactamase Inhibitors

  摘要：

  AbstractMetallo‐β‐lactamases (MBLs) are increasingly involved as a major mechanism of resistance to carbapenems in relevant opportunistic Gram‐negative pathogens. Unfortunately, clinically efficient MBL inhibitors still represent an unmet medical need. We previously reported several series of compounds based on the 1,2,4‐triazole‐3‐thione scaffold. In particular, Schiff bases formed between diversely 5‐substituted‐4‐amino compounds and 2‐carboxybenzaldehyde were broad‐spectrum inhibitors of VIM‐type, NDM‐1 and IMP‐1 MBLs. Unfortunately, these compounds were unable to restore antibiotic susceptibility of MBL‐producing bacteria, probably because of poor penetration and/or susceptibility to hydrolysis. To improve their microbiological activity, we synthesized and characterized compounds where the hydrazone‐like bond of the Schiff base analogues was replaced by a stable ethyl link. This small change resulted in a narrower inhibition spectrum, as all compounds were poorly or not inhibiting NDM‐1 and IMP‐1, but showed a significantly better activity on VIM‐type enzymes, with Ki values in the μM to sub‐μM range. The resolution of the crystallographic structure of VIM‐2 in complex with one of the best inhibitors yielded valuable information about their binding mode. Interestingly, several compounds were shown to restore the β‐lactam susceptibility of VIM‐type‐producing E. coli laboratory strains and also of K. pneumoniae clinical isolates. In addition, selected compounds were found to be devoid of toxicity toward human cancer cells at high concentration, thus showing promising safety.

  日期：——

  Despite the relatively low reactivities of urea and thiourea functional groups towards nucleophilic attack, we have found conditions in which they are useful substrates in Friedel-Crafts reactions. The Bronsted superacid, triflic acid, promotes these reactions and a mechanism is proposed involving dicationic, superelectrophilic intermediates.

  at the ether oxygen, the least basic heteroatom, is essential to promote CO bond cleavage. However, the carbonyl oxygen of carbamates, the most basic site, is protonated exclusively in strong acids. We found that the protonation site can be shifted to an alternative basic atom by linking methyl salicylate to the ether oxygen of carbamate. The methyl ester oxygen ortho to the phenolic (ether) oxygen
