Abstract
![]()
The use of antibiotics is threatened by the emergence
and spread
of multidrug-resistant strains of bacteria. Thus, there is a need
to develop antibiotics that address new targets. In this respect,
the bacterial divisome, a multi-protein complex central to cell division,
represents a potentially attractive target. Of particular interest
is the FtsQB subcomplex that plays a decisive role in divisome assembly
and peptidoglycan biogenesis in E. coli. Here, we report the structure-based design of
a macrocyclic covalent inhibitor derived from a periplasmic region
of FtsB that mediates its binding to FtsQ. The bioactive conformation
of this motif was stabilized by a customized cross-link resulting
in a tertiary structure mimetic with increased affinity for FtsQ.
To increase activity, a covalent handle was incorporated, providing
an inhibitor that impedes the interaction between FtsQ and FtsB irreversibly. The covalent inhibitor reduced the growth of an outer
membrane-permeable E. coli strain,
concurrent with the expected loss of FtsB localization, and also affected
the infection of zebrafish larvae by a clinical E.
coli strain. This first-in-class inhibitor of a divisome
protein–protein interaction highlights the potential of proteomimetic
molecules as inhibitors of challenging targets. In particular, the
covalent mode-of-action can serve as an inspiration for future antibiotics
that target protein–protein interactions.

Filamentous Thermosensitive Mutant Z: An Appealing Target for Emerging Pathogens and a Trek on Its Natural Inhibitors. BIOLOGY 2022; 11:624. [PMID: 35625352 PMCID: PMC9138142 DOI: 10.3390/biology11050624] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/04/2022] [Revised: 03/18/2022] [Accepted: 04/01/2022] [Indexed: 12/14/2022]
Abstract
Antibiotic resistance is a major emerging issue in the health care sector, as highlighted by the WHO. Filamentous Thermosensitive mutant Z (Fts-Z) is gaining significant attention in the scientific community as a potential anti-bacterial target for fighting antibiotic resistance among several pathogenic bacteria. The Fts-Z plays a key role in bacterial cell division by allowing Z ring formation. Several in vitro and in silico experiments have demonstrated that inhibition of Fts-Z can lead to filamentous growth of the cells, and finally, cell death occurs. Many natural compounds that have successfully inhibited Fts-Z are also studied. This review article intended to highlight the structural-functional aspect of Fts-Z that leads to Z-ring formation and its contribution to the biochemistry and physiology of cells. The current trend of natural inhibitors of Fts-Z protein is also covered.

[PMID: 32901320 PMCID: PMC7683447 DOI: 10.1007/s10858-020-00343-9] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/16/2020] [Accepted: 08/17/2020] [Indexed: 05/09/2023]
Abstract
No matter the source of compounds, drug discovery campaigns focused directly on the target are entirely dependent on a consistent stream of reliable data that reports on how a putative ligand interacts with the protein of interest. The data will derive from many sources including enzyme assays and many types of biophysical binding assays such as TR-FRET, SPR, thermophoresis and many others. Each method has its strengths and weaknesses, but none is as information rich and broadly applicable as NMR. Here we provide a number of examples of the utility of NMR for enabling and providing ongoing support for the early pre-clinical phase of small molecule drug discovery efforts. The examples have been selected for their usefulness in a commercial setting, with full understanding of the need for speed, cost-effectiveness and ease of implementation.
