Eur J Med Chem 2021; 225:113785. [PMID: 34425311 DOI: 10.1016/j.ejmech.2021.113785] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2021] [Revised: 08/13/2021] [Accepted: 08/14/2021] [Indexed: 11/17/2022]
Abstract
HIV-1 reverse transcriptase (RT) plays a central role in the viral life cycle, and roughly half of the FDA-approved anti-HIV drugs are targeting RT. Nucleoside analogs (NRTIs) require cellular phosphorylation for binding to RT, and to bypass this rate-limiting path, we designed a new series of acyclic nucleoside phosphonate analogs as nucleoside triphosphate mimics, aiming at the chelation of the catalytic Mg2+ ions via a phosphonate and/or a carboxylic acid group. Novel synthetic procedures were developed to access these nucleoside phosphonate analogs. X-ray structures in complex with HIV-1 RT/dsDNA demonstrated that their binding modes are distinct from that of our previously reported compound series. The impact of chain length, chirality and linker atom have been discussed. The detailed structural understanding of these new compounds provides opportunities for designing new class of HIV-1 RT inhibitors.

Abstract
The use of the phosphonate motif featuring a carbon-phosphorous bond as bioisosteric replacement of the labile P–O bond is widely recognized as an attractive structural concept in different areas of medicinal chemistry, since it addresses the very fundamental principles of enzymatic stability and minimized metabolic activation. This review discusses the most influential successes in drug design with special emphasis on nucleoside phosphonates and their prodrugs as antiviral and cancer treatment agents. A description of structurally related analogs able to interfere with the transmission of other infectious diseases caused by pathogens like bacteria and parasites will then follow. Finally, molecules acting as agonists/antagonists of P2X and P2Y receptors along with nucleotidase inhibitors will also be covered. This review aims to guide readers through the fundamentals of nucleoside phosphonate therapeutics in order to inspire the future design of molecules to target infections that are refractory to currently available therapeutic options.

Abstract
The syntheses of acyclic nucleoside phosphonate (ANP) analogs linked with cyclic systems
are described in the present review. The purpose of the review is to report the methodology of
ANP analogs and to give an idea on the synthesis of a therapeutic structural feature of such analogs.
The cyclopropane systems were mainly prepared by diazomethane cyclopropanation catalyzed by
Pd(OAc)2, intramolecular alkylation, Kulinkovich cyclopropanation, and use of difluorocyclopropane,
and so forth. The preparation of methylenecyclopropane system was made by diazoacetate
cyclopropanation catalyzed by Rhodium followed by addition-elimination reactions. For the preparation
of a variety of tethered 1,2,3-triazole systems, 1,3-dipolar cycloaddition between azidealkylphosphonates
and propargylated nucleobases was mainly applied. The formation of various
phosphonate moieties was achieved via phosphonylation of alkoxide, cross-coupling between
BrZnCF2P (O)(OEt)2 with iodoalkens catalyzed by CuBr, Michaelis-Arbuzov reaction with phosphite,
and Rh(II)-catalyzed O-H insertion, and so forth.

Abstract
A new series of phosphonylated triazolo[4,5-b]pyridine (1-deaza-8-azapurine), imidazo[4,5-b]pyridine (1-deazapurine) and imidazo[4,5-b]pyridin-2(3H)-one (1-deazapurin-8-one) were synthesized from 2-chloro-3-nitropyridine and selected diethyl ɷ-aminoalkylphosphonates followed by reduction of the nitro group and cyclization. In the final step O,O-diethylphosphonates were transformed into the corresponding phosphonic acids. All synthesized compounds were evaluated in vitro for inhibitory activity against a broad variety of DNA and RNA viruses and their cytotoxic potencies were also established. Compound 12f showed marginal activity against cytomegalovirus Davis strain (EC50 = 76.47 μM) in human embryonic lung (HEL) cells while compounds 10g (EC50 = 52.53 μM) and 12l (EC50 = 61.70 μM) were minimally active against the varicella-zoster virus Oka strain in HEL cells. Compounds under investigation were not cytotoxic at the maximum concentration evaluated (100 µM).

Abstract
Malaria still affects around 200 million people and is responsible for more than 400,000 deaths per year, mostly children in subequatorial areas. This disease is caused by parasites of the Plasmodium genus. Only a few WHO-recommended treatments are available to prevent or cure plasmodial infections, but genetic mutations in the causal parasites have led to onset of resistance against all commercial antimalarial drugs. New drugs and targets are being investigated to cope with this emerging problem, including enzymes belonging to the main metabolic pathways, while nucleoside and nucleotide analogues are also a promising class of potential drugs. This review highlights the main metabolic pathways targeted for the development of potential antiplasmodial therapies based on nucleos(t)ide analogues, as well as the different series of purine-containing nucleoside and nucleotide derivatives designed to inhibit Plasmodium falciparum purine metabolism.

Abstract
Syntheses of α-branched alkyl and aryl substituted 9-[2-(phosphonomethoxy)ethyl]purines from substituted 1,3-dioxolanes have been developed. Key synthetic precursors, α-substituted dialkyl [(2-hydroxyethoxy)methyl]phosphonates were prepared via Lewis acid mediated cleavage of 1,3-dioxolanes followed by reaction with dialkyl or trialkyl phosphites. The best preparative yields were achieved under conditions utilizing tin tetrachloride as Lewis acid and triisopropyl phosphite. Attachment of purine bases to dialkyl [(2-hydroxyethoxy)methyl]phosphonates was performed by Mitsunobu reaction. Final α-branched 9-[2-(phosphonomethoxy)ethyl]purines were tested for antiviral, cytostatic and antiparasitic activity, the latter one determined as inhibitory activity towards Plasmodium falciparum enzyme hypoxanthine-guanine-xanthine phosphoribosyltransfesase. In most cases biological activity was only marginal.

Abstract
Transition state theory teaches that chemically stable mimics of enzymatic transition states will bind tightly to their cognate enzymes. Kinetic isotope effects combined with computational quantum chemistry provides enzymatic transition state information with sufficient fidelity to design transition state analogues. Examples are selected from various stages of drug development to demonstrate the application of transition state theory, inhibitor design, physicochemical characterization of transition state analogues, and their progress in drug development.

Abstract
As antiviral nucleosides containing a fluorine atom at 2'-position are endowed with increased stabilization of glycosyl bond, it was of interest to investigate the influence of three fluorine atoms at 2'- and 5'-positions of apiosyl nucleoside phosphonate analogues. Various pyrimidine and purine 2',5',5'-trifluoro-3'-hydroxy-apiose nucleoside phosphonic acid analogues were synthesized from 1,3-dihydroxyacetone. Electrophilic fluorination of lactone was performed using N-fluorodibenzenesulfonimide. Difluorophosphonation was performed by direct displacement of triflate intermediate with diethyl(lithiodifluoromethyl) phosphonate to give the corresponding (α,α-difluoroalkyl) phosphonate. Condensation successfully proceeded from a glycosyl donor with persilylated bases to yield nucleoside phosphonate analogues. Deprotection of diethyl phosphonates provided the final phosphonic acid sodium salts. The synthesized nucleoside analogues were subjected to antiviral screening against various viruses.

Abstract
Acyclic nucleoside phosphonates (ANPs) that contain a 6-oxopurine base are good inhibitors of the human and Plasmodium falciparum 6-oxopurine phosphoribosyltransferases (PRTs), key enzymes of the purine salvage pathway. Chemical modifications, based on the crystal structures of several inhibitors in complex with the human PRTase, led to the design of a new class of inhibitors--the aza-ANPs. Because of the negative charges of the phosphonic acid moiety, their ability to cross cell membranes is, however, limited. Thus, phosphoramidate prodrugs of the aza-ANPs were prepared to improve permeability. These prodrugs arrest parasitemia with IC50 values in the micromolar range against Plasmodium falciparum-infected erythrocyte cultures (both chloroquine-sensitive and chloroquine-resistant Pf strains). The prodrugs exhibit low cytotoxicity in several human cell lines. Thus, they fulfill two essential criteria to qualify them as promising antimalarial drug leads.

Abstract
A novel route for the synthesis of 2',3'-difluorinated 5'-deoxythreosyl phosphonic acid nucleosides from glyceraldehyde using the Horner-Emmons reaction in the presence of triethyl α-fluorophosphonoacetate is described. The second fluorination at the 2'-position was an electrophilic reaction performed using N-fluorodibenzenesulfonimide. Glycosylation reactions between the nucleosidic bases and glycosyl donor 9 generated nucleosides that were further phosphonated and hydrolyzed to produce the desired nucleoside analogues. The synthesized nucleoside analogues 13, 16, 20, and 23 were tested for anti- human immunodeficiency virus (HIV) activity as well as cytotoxicity. Adenine derivative 16 showed significant anti-HIV activity up to 100 μM.

Abstract
On the basis of the discovery that the threosyl nucleoside phosphonate PMDTA is a potent anti-HIV compound, we synthesized several 4'-trifluoromethyl-5'-deoxyapiosyl nucleoside phosphonic acids and evaluated their anti-HIV activity. An efficient synthetic route was optimized, starting from an α-trifluoromethyl-α,β-unsaturated ester. Glycosylation of the purine nucleosidic bases with a glycosyl donor yielded modified nucleoside intermediates, which were then phosphonated and hydrolyzed to provide the targeted nucleoside analogs. Once synthesized, the anti-HIV and cytotoxic activities of each analog were evaluated. None of the analogs showed significant anti-HIV activity at concentrations up to 100 μM.

Abstract
Novel small-molecule agents to treat Bordetella pertussis infections are highly desirable, as pertussis (whooping cough) remains a serious health threat worldwide. In this study, a series of 2-substituted derivatives of 9-[2-(phosphonomethoxy)ethyl]adenine (PMEA, adefovir), in their isopropyl ester bis(L-phenylalanine) prodrug form, were designed and synthesized as potent inhibitors of adenylate cyclase toxin (ACT) isolated from B. pertussis. The series consists of PMEA analogues bearing either a linear or branched aliphatic chain or a heteroatom at the C2 position of the purine moiety. Compounds with a small C2 substituent showed high potency against ACT without cytotoxic effects as well as good selectivity over human adenylate cyclase isoforms AC1, AC2, and AC5. The most potent ACT inhibitor was found to be the bisamidate prodrug of the 2-fluoro PMEA derivative (IC50 =0.145 μM). Although the bisamidate prodrugs reported herein exhibit overall lower activity than the bis(pivaloyloxymethyl) prodrug (adefovir dipivoxil), their toxicity and plasma stability profiles are superior. Furthermore, the bisamidate prodrug was shown to be more stable in plasma than in macrophage homogenate, indicating that the free phosphonate can be effectively distributed to target tissues, such as the lungs. Thus, ACT inhibitors based on acyclic nucleoside phosphonates may represent a new strategy to treat whooping cough.

Abstract
Novel 5'-deoxycarbocyclic purine phosphonic acid analogs with the 4'-electropositive moiety, fluorine were designed, and synthesized from glyceraldehyde. The cyclopentenol intermediate, 9, was successfully synthesized by the ring-closing metathesis of divinyl 8. The condensation reaction of cyclopentanol 15 with purine bases under Mitsunobu conditions successfully afforded the desired phosphonate analogs. The synthesized nucleoside phosphonic acid analogs, 19, 22, 26, and 29, were subjected to antiviral screening against human immunodeficiency virus (HIV)-1. Guanine phosphonic acid analog 29 showed significant anti-HIV activity (EC50 = 10.3 μM).

Abstract
The authors describe highly efficient synthetic routes for the preparation of novel 6',6'-difluoro 5'-deoxycarbocyclic phosphonic acid nucleosides from 1,4-dihydroxy-2-butene. The discovery that the 6'-fluorinated carbocyclic nucleoside (2, EC₅₀ = 0.16 μM) is a potent anti-HSV-1 agent led to the syntheses and biological evaluations of 6'-modified 5'-deoxyversions of carbocyclic phosphonate nucleosides. The synthesized nucleoside analogues 15, 18, 22, and 25 were tested for anti-HIV activity and for cytotoxicity. However, none of them showed significant anti-HIV-1 activity or cytotoxicity at concentrations up to 100 μM.

The heterotrimeric influenza virus polymerase performs replication and transcription of viral RNA in the nucleus of infected cells. Transcription by "cap-snatching" requires that host-cell pre-mRNAs are bound via their 5' cap to the PB2 subunit. Thus, the PB2 cap-binding site is potentially a good target for new antiviral drugs that will directly inhibit viral replication. Docking studies using the structure of the PB2 cap-binding domain suggested that 7-alkylguanine derivatives substituted at position N-9 and N-2 could be good candidates. Four series of 7,9-di- and 2,7,9-trialkyl guanine derivatives were synthesized and evaluated by an AlphaScreen assay in competition with a biotinylated cap analogue. Three synthesized compounds display potent in vitro activity with IC50 values lower than 10 μM. High-resolution X-ray structures of three inhibitors in complex with the H5N1 PB2 cap-binding domain confirmed the binding mode and provide detailed information for further compound optimization.

Abstract
A very efficient synthetic route to novel 3'-hydroxymethyl 5'-deoxythreosyl phosphonic acid nucleosides was described. The discovery of threosyl phosphonate nucleoside (PMDTA, EC(50) = 2.53 μM) as a potent antihuman immunodeficiency virus (anti-HIV) agent has led to the synthesis and biological evaluation of 3'-modified 5'-deoxy versions of the threosyl phosphonate nucleosides. 3'-Hydroxymethyl 5 '-deoxythreosyl phosphonic acid nucleoside analogues 15, 19, 24, and 28 were synthesized from 1,3-dihydroxyacetone and tested for anti-HIV activity as well as cytotoxicity. The adenine analogue 19 exhibits moderate in vitro anti-HIV-1 activity (EC(50) = 10.2 μM).

Abstract
A general procedure for the preparation of 1,2,3-triazole analogs of nucleosides from diethyl 2-azidoethoxymethyl- and 2-azidoethoxyethylphosphonates was elaborated. The application of microwave irradiation shortened the reaction time to 10 min in comparison to ca. 48 h when 1,3-dipolar cycloadditions were performed under standard conditions. All compounds were evaluated in vitro for inhibitory activity against a broad variety of DNA and RNA viruses. None of the compounds were antivirally active at subtoxic concentrations. Compound 17k exhibited moderate inhibitory effects on the proliferation of human T-lymphocyte cells (IC50=64 µM for CEM).

Abstract
Novel 5'-deoxyfuranosyl purine phosphonic acid analogues with 2 '-electropositive moiety, such as spirocyclopropanoid, were designed and synthesized from commercially available diethyl malonate. Condensation reaction successfully proceeded from a glycosyl donor 15 at low reaction temperature in Vorbruggen conditions to give desired phosphonate analogues 16b and 23b. The synthesized nucleotide analogues 19, 22, 26, and 29 were subjected to antiviral screening against HIV-1. Adenine phosphonic acid analogue 22 shows significant anti-HIV activity (EC(50) = 7.9 μM).
