Increasing antimicrobial resistance is evolving to be one of the major threats to public health. To reduce the selection pressure and thus to avoid a fast development of resistance, novel approaches aim to target bacterial virulence instead of growth. Another strategy is to restore the activity of antibiotics already in clinical use. This can be achieved by the inhibition of resistance factors such as metallo-β-lactamases (MBLs). Since MBLs can cleave almost all β-lactam antibiotics, including the “last resort” carbapenems, their inhibition is of utmost importance. Here, we report on the synthesis andin vitroevaluation ofN-aryl mercaptoacetamides as inhibitors of both clinically relevant MBLs and the virulence factor LasB fromPseudomonas aeruginosa. All testedN-aryl mercaptoacetamides showed low micromolar to submicromolar activities on the tested enzymes IMP-7, NDM-1 and VIM-1. The two most promising compounds were further examined in NDM-1 expressingKlebsiella pneumoniaeisolates, where they restored the full activity of imipenem. Together with their LasB-inhibitory activity in the micromolar range, this class of compounds can now serve as a starting point for a multi-target inhibitor approach against both bacterial resistance and virulence, which is unprecedented in antibacterial drug discovery.

The relevance of Retinoic acid receptor-related orphan receptors in cancer progression has sparked interest in developing multifunctional therapeutics. In the search for potentially active novel compounds with anticancer characteristics, the Gewald reaction was employed to develop different thiophene derivatives (8a–8i). Physicochemical and spectroanalytical investigations verified the molecular structures of the synthesized derivatives. Using an in vitro primary anticancer assay, NCI chose all of the synthesized molecules as prototypes and assessed their anticancer efficacy against a panel of various cancer cell lines representing nine distinct neoplasms. The compounds were found to have a wide range of anticancer activity. Following significant anticancer efficacy against all cell lines in the initial screening, compound 8e was chosen for a five-dose test. Compound 8e inhibited growth at concentrations ranging from 0.411 to 2.8 μM. The antioxidant activity of the compounds was further evaluated using the radical scavenging action of the stable DPPH free radical. In comparison to Ascorbic Acid, compounds 8e and 8i showed outstanding antioxidant activity, while the remaining compounds in the series demonstrated acceptable antioxidant activity. In a molecular docking investigation, 8e demonstrated excellent docking scores inside the binding pocket of the specified pdb-id (6q7a), complementing the results of anticancer screening. Based on our results, novel ethyl 5-acetyl-2-amino-4-methylthiophene-3-carboxylate derivatives could be useful in the development of potential anticancer treatments.
