Exploring fluorinated heptose phosphate analogues as inhibitors of HldA and HldE, key enzymes in the biosynthesis of lipopolysaccharide. Bioorg Chem 2024; 153:107767. [PMID: 39241584 DOI: 10.1016/j.bioorg.2024.107767] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2024] [Revised: 08/16/2024] [Accepted: 08/26/2024] [Indexed: 09/09/2024]
Abstract
The growing threat of bacterial resistance to antibiotics has led to the rise of anti-virulence strategies as a promising approach. These strategies aim to disarm bacterial pathogens and improve their clearance by the host immune system. Lipopolysaccharide, a key virulence factor in Gram-negative bacteria, has been identified as a potential target for anti-virulence agents. In this study, we focus on inhibiting HldA and HldE, bacterial enzymes from the heptose biosynthesis pathway, which plays a key role in lipopolysaccharide biosynthesis. We present the synthesis of two fluorinated non-hydrolysable heptose phosphate analogues. Additionally, the inhibitory activity of a family of eight heptose phosphate analogues against HldA and HldE was assessed. This evaluation revealed inhibitors with affinities in the low μM range, with the most potent compound showing inhibition constant values of 15.4 μM for HldA and 16.9 μM for HldE. The requirement for a phosphate group at the C-7 position was deemed essential for inhibitory activity, while the presence of a hydroxy anomeric group was found to be beneficial, a phenomenon rationalized through computational modeling. Additionally, the introduction of a single fluorine atom α to the phosphonate moiety conferred a slight advantage for inhibition. These findings suggest that mimicking the structure of d-glycero-β-d-manno-heptose 1,7-bisphosphate, the product of the phosphorylation step in heptose biosynthesis, could be a promising strategy to disrupt this biosynthetic pathway. In terms of the in vivo effects, these heptose phosphate analogues neither demonstrated significant LPS-disrupting effects nor exhibited growth inhibitory activity on their own. Additionally, they did not alter the susceptibility of bacteria to hydrophobic antibiotics. The highly charged nature of these molecules may hinder their ability to penetrate the bacterial cell wall. To overcome this limitation, alternative strategies such as incorporating protecting groups that facilitate their entry and can subsequently be cleaved within the bacterial cytoplasm could be explored.

Abstract
Inhibition of the biosynthesis of bacterial heptoses opens novel perspectives for antimicrobial therapies. The enzyme GmhA responsible for the first committed biosynthetic step catalyzes the conversion of sedoheptulose 7-phosphate into d-glycero-d-manno-heptose 7-phosphate and harbors a Zn2+ ion in the active site. A series of phosphoryl- and phosphonyl-substituted derivatives featuring a hydroxamate moiety were designed and prepared from suitably protected ribose or hexose derivatives. High-resolution crystal structures of GmhA complexed to two N-formyl hydroxamate inhibitors confirmed the binding interactions to a central Zn2+ ion coordination site. Some of these compounds were found to be nanomolar inhibitors of GmhA. While devoid of HepG2 cytotoxicity and antibacterial activity of their own, they demonstrated in vitro lipopolysaccharide heptosylation inhibition in Enterobacteriaceae as well as the potentiation of erythromycin and rifampicin in a wild-type Escherichia coli strain. These inhibitors pave the way for a novel treatment of Gram-negative infections.

A conservative distribution of tridomain NDP-heptose synthetases in actinobacteria. SCIENCE CHINA-LIFE SCIENCES 2021; 65:1014-1023.

Abstract
Heptoses are important structural components of Gram-negative bacterium cell wall and participate in bacterial colonization, infection, and immune recognition. Current knowledge of NDP-heptose originating from d-sedoheptulose 7-phosphate in Grampositive bacterium remains limited. Here, in silico analysis suggested that the special tridomain NDP-heptose synthetases with isomerase, kinase, and nucleotidyltransferase activities are conservatively distributed in Actinobacteria class of Gram-positive bacterium. Enzymatical characterization of the tridomain proteins from different strains showed that they are involved in ADP-d-glycero-β-d-manno-heptose biosynthesis despite the unexpected discovery of kinase activities deficient in some proteins. The presence of three types of NDP-heptose synthetases in Gram-positive bacterium suggests that it is also a rich source of heptoses and the heptose moieties may play important roles in vivo. Our work updates the understanding of NDP-heptose biosynthesis in Gram-positive bacterium and lays a solid foundation for further physiological function explorations.

Abstract
The persistence of Helicobacter pylori in the human gastric mucosa implies that the immune response fails to clear the infection. We found that H. pylori compromises the antigen presentation ability of macrophages, because of the decline of the presenting molecules HLA-II. Here, we reveal that the main bacterial factor responsible for this effect is ADP-heptose, an intermediate metabolite in the biosynthetic pathway of lipopolysaccharide (LPS) that elicits a pro-inflammatory response in gastric epithelial cells. In macrophages, it upregulates the expression of miR146b which, in turn, would downmodulate CIITA, the master regulator for HLA-II genes. Hence, H. pylori, utilizing ADP-heptose, exploits a specific arm of macrophage response to establish its survival niche in the face of the immune defense elicited in the gastric mucosa.

Abstract
Covering: up to 2020Glycosylated natural products hold great potential as drugs for the treatment of human and animal diseases. Heptoses, known as seven-carbon-chain-containing sugars, are a group of saccharides that are rarely observed in natural products. Based on the structures of the heptoses, the heptose-containing natural products can be divided into four groups, characterized by heptofuranose, highly-reduced heptopyranose, d-heptopyranose, and l-heptopyranose. Many of them possess remarkable biological properties, including antibacterial, antifungal, antitumor, and pain relief activities, thereby attracting great interest in biosynthesis and chemical synthesis studies to understand their construction mechanisms and structure-activity relationships. In this review, we summarize the structural properties, biological activities, and recent progress in the biosynthesis of bacterial natural products featuring seven-carbon-chain-containing sugars. The biosynthetic origins of the heptose moieties are emphasized.

Abstract
Great successes have been achieved in developing small-molecule kinase inhibitors as anticancer therapeutic agents. However, kinase deregulation plays essential roles not only in cancer but also in almost all major disease areas. Accumulating evidence has revealed that kinases are promising drug targets for different diseases, including cancer, autoimmune diseases, inflammatory diseases, cardiovascular diseases, central nervous system disorders, viral infections, and malaria. Indeed, the first small-molecule kinase inhibitor for treatment of a nononcologic disease was approved in 2011 by the U.S. FDA. To date, 10 such inhibitors have been approved, and more are in clinical trials for applications other than cancer. This Perspective discusses a number of kinases and their small-molecule inhibitors for the treatment of diseases in nononcologic therapeutic fields. The opportunities and challenges in developing such inhibitors are also highlighted.

Abstract
The Gram-negative bacterium Burkholderia pseudomallei is the causative agent of melioidosis. D-glycero-β-D-manno-Heptose-1-phosphate adenylyltransferase (HldC) is the fourth enzyme of the ADP-L-glycero-β-D-manno-heptose biosynthesis pathway, which produces an essential carbohydrate comprising the inner core of lipopolysaccharide. Therefore, HldC is a potential target of antibiotics against melioidosis. In this study, HldC from B. pseudomallei has been cloned, expressed, purified and crystallized. Synchrotron X-ray data from a selenomethionine-substituted HldC crystal were also collected to 2.8 Å resolution. The crystal belonged to the primitive triclinic space group P1, with unit-cell parameters a = 74.0, b = 74.0, c = 74.9 Å, α = 108.4, β = 108.4, γ = 108.0°. Eight protomers are present in the unit cell and three out of five selenomethionines were found in each protomer using the PHENIX software suite. A full structural determination is in progress to elucidate the structure-function relationship of the protein.

Abstract
Gram-negative bacteria utilize heptoses as part of their repertoire of extracellular polysaccharide virulence determinants. Disruption of heptose biosynthesis offers an attractive target for novel antimicrobials. A critical step in the synthesis of heptoses is their 1-O phosphorylation, mediated by kinases such as HldE or WcbL. Here, we present the structure of WcbL from Burkholderia pseudomallei. We report that WcbL operates through a sequential ordered Bi-Bi mechanism, loading the heptose first and then ATP. We show that dimeric WcbL binds ATP anti-cooperatively in the absence of heptose, and cooperatively in its presence. Modeling of WcbL suggests that heptose binding causes an elegant switch in the hydrogen-bonding network, facilitating the binding of a second ATP molecule. Finally, we screened a library of drug-like fragments, identifying hits that potently inhibit WcbL. Our results provide a novel mechanism for control of substrate binding and emphasize WcbL as an attractive anti-microbial target for Gram-negative bacteria.
