J Control Release 2024; 365:759-772. [PMID: 38086445 DOI: 10.1016/j.jconrel.2023.12.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2023] [Revised: 12/07/2023] [Accepted: 12/08/2023] [Indexed: 12/17/2023]
Abstract
The cation-independent mannose 6-phosphate receptor (CI-M6PR) is a ubiquitous transmembrane receptor whose main intracellular role is to direct enzymes carrying mannose 6-phosphate moieties to lysosomal compartments. Recently, the small membrane-bound portion of this receptor has appeared to be implicated in numerous pathophysiological processes. This review presents an overview of the main ligand partners and the roles of CI-M6PR in lysosomal storage diseases, neurology, immunology and cancer fields. Moreover, this membrane receptor has already been noted for its strong potential in therapeutic applications thanks to its cellular internalization activity and its ability to address pathogenic factors to lysosomes for degradation. A number of therapeutic delivery approaches using CI-M6PR, in particular with enzymes, antibodies or nanoparticles, are currently being proposed.

Abstract
Following injurious stimuli, quiescent hepatic stellate cells (qHSCs) transdifferentiate into activated HSCs (aHSCs). aHSCs play pivotal roles in the onset and progression of liver fibrosis. Therefore, molecular imaging of aHSCs in liver fibrosis will facilitate early diagnosis, prognosis prediction, and instruction and evaluation of aHSC-targeted treatment. To date, several receptors, such as integrin αvβ3, mannose 6-phosphate/insulin-like growth factor II receptor (M6P/IGF-IIR), collagen type VI receptor (CVIR), platelet-derived growth factor receptor-β (PDGFR-β), vimentin, and desmin, have been identified as biomarkers of aHSCs. Corresponding ligands to these receptors have also been developed. This review will discuss strategies for developing aHSC-targeted imaging in liver fibrosis.

Abstract
Glucose-6-phosphatase (G6Pase) is an essential metabolic enzyme that has upregulated activity in Type II diabetes. Synthetic analogs of the G6Pase substrate, glucose-6-phosphate (G6P), may provide new tools to probe enzyme activity, or lead to specific inhibitors of glycosylphosphatase enzymes. Here we have developed synthetic routes to a panel of non-hydrolyzable G6P analogs containing α-bromo, α,α-dibromo, and α-bromo-α,β-unsaturated phosphonates compatible with a carbohydrate nucleus. We confirm that these functionalities have potency as inhibitors of G6Pase in vitro, providing a series of new phosphate isosteres that can be exploited for inhibitor design.

Abstract
D-glucuronate and l-iduronate containing disaccharides related to the antithrombin-binding pentasaccharide of heparin, in which one of the sulfate esters is systematically replaced by a sodium sulfonatomethyl moiety, were synthesized. The sulfonic acid group was introduced by stereoselective radical addition onto the exomethylene moiety of the appropriate glycoside derivatives, and the resulting sulfonatomethyl glucosides were used as acceptors.

Synthesis and evaluation of non-hydrolyzable D-mannose 6-phosphate surrogates reveal 6-deoxy-6-dicarboxymethyl-D-mannose as a new strong inhibitor of phosphomannose isomerases. Bioorg Med Chem 2009; 17:7100-7.

Abstract
Non-hydrolyzable d-mannose 6-phosphate analogues in which the phosphate group was replaced by a phosphonomethyl, a dicarboxymethyl, or a carboxymethyl group were synthesized and kinetically evaluated as substrate analogues acting as potential inhibitors of type I phosphomannose isomerases (PMIs) from Saccharomyces cerevisiae and Escherichia coli. While 6-deoxy-6-phosphonomethyl-d-mannose and 6-deoxy-6-carboxymethyl-D-mannose did not inhibit the enzymes significantly, 6-deoxy-6-dicarboxymethyl-D-mannose appeared as a new strong competitive inhibitor of both S. cerevisiae and E. coli PMIs with K(m)/K(i) ratios of 28 and 8, respectively. We thus report the first malonate-based inhibitor of an aldose-ketose isomerase to date. Phosphonomethyl mimics of the 1,2-cis-enediolate high-energy intermediate postulated for the isomerization reaction catalyzed by PMIs were also synthesized but behave as poor inhibitors of PMIs. A polarizable molecular mechanics (SIBFA) study was performed on the complexes of d-mannose 6-phosphate and two of its analogues with PMI from Candida albicans, an enzyme involved in yeast infection homologous to S. cerevisiae and E. coli PMIs. It shows that effective binding to the catalytic site occurs with retention of the Zn(II)-bound water molecule. Thus the binding of the hydroxyl group on C1 of the ligand to Zn(II) should be water-mediated. The kinetic study reported here also suggests the dianionic character of the phosphate surrogate as a likely essential parameter for strong binding of the inhibitor to the enzyme active site.

Abstract
A new synthetic route to obtain the carboxylate analog of mannose 6-phosphate (M6-P) is presented. The effects of the M6-P, the carboxylate and two other analogs (the phosphonate and the alpha,beta ethylenic carboxylate) on the proliferation of human keratinocytes and dermal fibroblasts as well as on the proliferation of a murine fibroblast cell line, 3T3-J2 are tested. We observed that M6-P is a potent inhibitor of proliferation of both fibroblasts and keratinocytes. Among its analogs, the phosphonate showed a similar effect on human dermal fibroblasts but not on keratinocytes.

Abstract
The first direct generation of synthetically useful alpha-phosphonovinyl radicals was achieved by treatment of alpha-phosphonovinyl halides with a tributyltin radical. The alpha-phosphonovinyl radicals 2a-d were trapped with electron-rich olefins and an electron-deficient olefin to produce alpha-functionalized vinylphosphonates 3a-f in 16-55% yields. The alpha-phosphonovinyl radicals 7e-g containing the YCH2CH=CH2 (Y = O, CH2, S) substituent at the beta-position afforded mixtures of 5-exo and 6-endo cyclization products, 5e-g and 6e-g, in good yields. The 5-exo/6-endo product ratios increase in the following order of the beta-substituent: OCH2CH=CH2 > CH2CH2CH=CH2 > SCH2CH=CH2. The effects of the beta-substituents upon the cyclization reaction were discussed. Radical cyclization of alpha-phosphonovinyl radicals bearing functional groups such as geranyloxy, geranylthio, and (2-cyclohexen-1-yl)thio groups at the beta-position afforded 5-exo, 5-exo and 6-endo, and cis-fused-5,6-ring cyclization products incorporating an alpha,beta-unsaturated phosphonate unit within the ring, respectively, in good yields. The alpha-phosphonovinyl radical 20 underwent tandem radical cyclization-radical cyclization to produce a mixture of two isomeric bicyclo[4.3.0]nonenes including a vinylphosphonate moiety in high yield.

Abstract
The enzyme 3-deoxy-D-manno-2-octulosonate-8-phosphate (KDO8P) synthase catalyzes the condensation reaction between phosphoenolpyruvate (PEP) and D-arabinose 5-phosphate (A5P) to produce KDO8P and inorganic phosphate. In attempts to investigate the lack of antibacterial activity of the most potent inhibitor of KDO8P synthase, the amino phosphonophosphate 3, we have synthesized its hydrolytically stable isosteric phosphonate analogue 4 and tested it as an inhibitor of the enzyme. The synthesis of 4 was accomplished in a one step procedure by employing the direct reductive amination in aqueous media between unprotected sugar phosphonate and glyphosate. The analogue 4 proved to be a competitive inhibitor of KDO8P synthase with respect to both substrates A5P and PEP binding. In vitro antibacterial tests against a series of different Gram-negative organisms establish that both inhibitors (3 and 4) lack antibacterial activity probably due to their reduced ability to penetrate the bacterial cell membrane.

Abstract
Three new analogues of mannose 6-phosphate (M6P)--a sulphate and two carboxylates--have been synthesized and their affinity toward the M6P/IGFII receptor evaluated by affinity column chromatography. These compounds display strong binding to the receptor and therefore are new M6P analogues which may find some dermatological applications, for example healing of post-surgical scars.
