New MraY AA Inhibitors with an Aminoribosyl Uridine Structure and an Oxadiazole. Antibiotics (Basel) 2022; 11:antibiotics11091189. [PMID: 36139968 PMCID: PMC9495235 DOI: 10.3390/antibiotics11091189] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2022] [Revised: 08/22/2022] [Accepted: 08/30/2022] [Indexed: 11/16/2022] Open
Abstract
New inhibitors of the bacterial transferase MraY from Aquifex aeolicus (MraYAA), based on the aminoribosyl uridine central core of known natural MraY inhibitors, have been designed to generate interaction of their oxadiazole linker with the key amino acids (H324 or H325) of the enzyme active site, as observed for the highly potent inhibitors carbacaprazamycin, muraymycin D2 and tunicamycin. A panel of ten compounds was synthetized notably thanks to a robust microwave-activated one-step sequence for the synthesis of the oxadiazole ring that involved the O-acylation of an amidoxime and subsequent cyclization. The synthetized compounds, with various hydrophobic substituents on the oxadiazole ring, were tested against the MraYAA transferase activity. Although with poor antibacterial activity, nine out of the ten compounds revealed the inhibition of the MraYAA activity in the range of 0.8 µM to 27.5 µM.

[PMID: 33607457 DOI: 10.1016/j.ejmech.2021.113272] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2020] [Revised: 01/21/2021] [Accepted: 02/02/2021] [Indexed: 11/27/2022]
Abstract
Antibiotic resistance is one of the most challenging global health issues and presents an urgent need for the development of new antibiotics. In this regard, phospho-MurNAc-pentapeptide translocase (MraY), an essential enzyme in the early stages of peptidoglycan biosynthesis, has emerged as a promising new antibiotic target. We recently reported the crystal structures of MraY in complex with representative members of naturally occurring nucleoside antibiotics, including muraymycin D2. However, these nucleoside antibiotics are synthetically challenging targets, which limits the scope of medicinal chemistry efforts on this class of compounds. To gain access to active muraymycin analogs with reduced structural complexity and improved synthetic tractability, we prepared and evaluated cyclopentane-based muraymycin analogs for targeting MraY. For the installation of the 1,2-syn-amino alcohol group of analogs, the diastereoselective isocyanoacetate aldol reaction was explored. The structure-activity relationship analysis of the synthesized analogs suggested that a lipophilic side chain is essential for MraY inhibition. Importantly, the analog 20 (JH-MR-23) showed antibacterial efficacy against Staphylococcus aureus. These findings provide insights into designing new muraymycin-based MraY inhibitors with improved chemical tractability.
