Methicillin-resistant Staphylococcus aureus (MRSA) has become a major threat on public health because of the increase of clinically isolated strains that exhibit resistance to many antibiotics. Therefore, development of new antibiotics for the treatment of MRSA infection is a sustained challenge. We have previously identified a ring-opened bengamide analogue L472-2 that displays moderate activity against the growth of S. aureus. In our previous work, we started from L472-2 and identified a class of analogues containing alkynyl groups which have the potential to activate SaClpP activity but moderate antibacterial activity. Herein, we focused on the antibacterial activity of L472-2, and a novel series of ring-opened bengamide analogues were synthesized and their activities were evaluated against MRSA. By conducting a compact analysis of the structure-activity relationships (SAR) of these analogues, we found that an adamantane ethanol ester bengamide 2j showed excellent antibacterial activity towards six S. aureus strains, including MRSA, while it does not activate ClpP. Therefore, these bengamide analogues represent a new class of candidates that suppress MRSA viability.

A series of novel α-sulfonyl γ-(glycinyl-amino)proline peptidomimetic derivatives were designed, synthesized and assayed for their activities against matrix metalloproteinase-2 (MMP-2), aminopeptidase N (APN)/CD13 and HDACs. The results indicated that all the compounds exhibited highly selective inhibition against MMP-2 as compared with APN and HDACs. The antiproliferative activities of some compounds against SKOV3, HL60 and A549 cells were also investigated. Comparing with the control LY52, compound 12u, with excellent activity both in the enzymatic inhibition assay and cell-based assay, could be used as lead compound for the further development of MMP inhibitors.

The syntheses of N-protected dipeptide acids using alkaline earth metal (Mg, Ca, and Ba) carboxylates of an amino acid in organic solvents were investigated. It was found that amino acid calcium carboxylates are the most effective among the carboxylates of the amino acids tested for coupling with active esters of Boc-Ala-OH in organic solvents. The coupling of Boc-Ala-ONp or Boc-Ala-ONSu with amino acid calcium carboxylates in DMF gave the desired N-protected dipeptide acids in high yields (92-100%). Georg Thieme Verlag Stuttgart - New York.
