Sustainable Protocol for the Synthesis of 2',3'-Dideoxynucleoside and 2',3'-Didehydro-2',3'-dideoxynucleoside Derivatives
Molecules 2022 Jun 21;27(13):3993.PMID:35807233DOI:10.3390/molecules27133993.
An improved protocol for the transformation of ribonucleosides into 2',3'-dideoxynucleoside and 2',3'-didehydro-2',3'-dideoxynucleoside derivatives, including the anti-HIV drugs stavudine (d4T), zalcitabine (ddC) and didanosine (ddI), was established. The process involves radical deoxygenation of xanthate using environmentally friendly and low-cost reagents. Bromoethane or 3-bromopropanenitrile was the alkylating agent of choice to prepare the ribonucleoside 2',3'-bisxanthates. In the subsequent radical deoxygenation reaction, tris(trimethylsilyl)silane and 1,1'-azobis(cyclohexanecarbonitrile) were used to replace hazardous Bu3SnH and AIBN, respectively. In addition, TBAF was substituted for camphorsulfonic acid in the deprotection step of the 5'-O-silyl ether group, and an enzyme (adenosine deaminase) was used to transform 2',3'-Dideoxyadenosine into 2',3'-dideoxyinosine (ddI) in excellent yield.
Antibacterial activity of 2',3'-Dideoxyadenosine in vivo and in vitro
Antimicrob Agents Chemother 1981 Mar;19(3):424-8.PMID:6972730DOI:10.1128/AAC.19.3.424.
2',3'-Dideoxyadenosine (DDA) was shown not only to possess antibacterial activity in vitro against a variety of Enterobacteriaceae, but also to be effective in vivo, DDA was active in experimental mouse infections by the oral route against 5 Salmonella strains, 2 of 3 Arizona strains, 5 of 7 Citrobacter strains, 3 of 8 Klebsiella strains, 3 of 5 Escherichia strains, 1 of 3 Shigella strains, and 3 of 15 Serratia strains at concentrations generally well below the toxic level. Closely related compounds, with the exception of 2',3'-dideoxyinosine, were found to be inactive in vivo, indicating that a high degree of structural specificity was required for activity. The synthesis of deoxyribonucleic acid was inhibited by DDA in those strains susceptible in vitro to DDA, whereas ribonucleic acid and protein syntheses were not affected. The concentration of DDA which inhibited bacterial deoxyribonucleic acid synthesis by 50% was calculated based on the relative rates of deoxyribonucleic acid synthesis in ;the absence and in the presence of DDA. This value correlated well with the minimal inhibitory concentration determined by the in vitro broth dilution assay but not always with in vivo activity determined by the mouse protection test.
Production of 2',3'-Dideoxyadenosine and 2',3'-dideoxyinosine from 2',3'-dideoxyuridine and the corresponding purine bases by resting cells of Escherichia coli AJ 2595
Appl Environ Microbiol 1989 Feb;55(2):419-24.PMID:2497709DOI:10.1128/aem.55.2.419-424.1989.
A novel microbial method for the production of 2',3'-dideoxynucleosides by transdideoxyribosylation has been developed. By screening microorganisms producing 2',3'-Dideoxyadenosine (DDA) from 2',3'-dideoxyuridine (DDU) and adenine, Escherichia coli AJ 2595 was selected as the best producer. Optimal pH and temperature for the DDA-producing reaction were ca. 6.5 and 50 degrees C, respectively. Pi seemed to be an essential factor for the reaction, and its optimal concentration was ca. 25 mM. Moreover, polyethylene glycol had a notable effect on DDA production. Under the best conditions established, 52 mM DDA was obtained from 100 mM DDU and 100 mM adenine after 48 h of incubation from resting cells of E. coli AJ 2595. This strain could also produce 2',3'-dideoxynucleosides, such as 2',3'-dideoxyinosine (DDI), 2',3'-dideoxyguanosine, and 2',3'-dideoxythymidine, from DDU and the corresponding bases. In particular, this strain could produce DDI in high yield (ca. 32 mM from 100 mM DDU and 100 mM hypoxanthine) after 24 h of incubation. However, 2',3'-dideoxycytidine was not produced from DDU and cytosine by resting cells of E. coli AJ 2595.
2',3'-Dideoxyadenosine is selectively toxic for TdT-positive cells
Blood 1988 Jun;71(6):1601-8.PMID:2836001doi
The 2',3'-dideoxynucleosides (ddNs) are currently undergoing clinical evaluation as antiretroviral agents in HIV-infected individuals. When phosphorylated, the ddNs (ddNTPs) function as chain-terminating substrate analogues with reverse transcriptase, thereby inhibiting HIV replication. These nucleoside analogues can also inhibit, by chain-terminating additions, the primitive lymphoid DNA polymerase, terminal deoxynucleotidyl transferase (TdT). To determine the effect of possible intracellular chain-terminating additions of ddNMPs by TdT, we exposed a series of TdT-positive and TdT-negative cell lines to 2',3'-Dideoxyadenosine (ddA), a representative ddN. At ddA concentrations 25-fold higher than required for inhibition of HIV replication, progressive dose-related cytotoxicity was observed in the TdT-positive cell lines. This was accentuated by the adenosine deaminase inhibitor Coformycin (CF), presumably by enhancing the intracellular generation of ddATP from ddA. A central role of TdT in mediating the ddA/CF cytotoxicity was suggested by studies in a pre-B-cell line rendered TdT positive by infection with a TdT cDNA-containing retroviral vector. After a 48-hour continuous exposure period to 250 mumol/L ddA and 30 mumol/L CF, 30% cell death was observed in the TdT-negative parental line, whereas 90% cell death was observed in the TdT-positive daughter line. Exposure of fresh TdT-positive leukemic cells to ddA/CF for 72 hours ex vivo resulted in cytotoxicity (six cases of acute lymphocytic leukemia [ALL]) while not affecting TdT-negative acute leukemic cells (six cases). We conclude that ddA/CF selectively damages TdT-positive cells, presumably by chain-terminating additions of ddAMP, and that this may have therapeutic relevance in TdT-positive malignant disease.
Metabolism and anti-human immunodeficiency virus-1 activity of 2-halo-2',3'-dideoxyadenosine derivatives
J Biol Chem 1988 Apr 25;263(12):5870-5.PMID:3258602doi
Both 2',3'-Dideoxyadenosine and 2',3'-dideoxyinosine have been shown (Mitsuya, H., and Broder, S. (1987) Nature 325, 773-778) to have in vitro activity against the human immunodeficiency virus-1 (HIV). However, these dideoxynucleosides may be catabolized by human T cells, even when adenosine deaminase is inhibited by deoxycoformycin. To overcome this problem, we have synthesized the 2-fluoro-, 2-chloro-, and 2-bromo-derivatives of 2',3'-Dideoxyadenosine. The metabolism and anti-HIV activity of the 2-halo-2',3'-dideoxyadenosine derivatives and of 2',3'-Dideoxyadenosine were compared. The 2-halo-2',3'-dideoxyadenosine derivatives were not deaminated significantly by cultured CEM T lymphoblasts. Experiments with 2-chloro-2',3'-dideoxyadenosine showed that the T cells converted the dideoxynucleoside to the 5'-monophosphate, 5'-diphosphate, and 5'-triphosphate metabolites. At concentrations lower than those producing cytotoxicity in uninfected cells (3-10 microM), the 2-halo-2',3-dideoxyadenosine derivatives inhibited the cytopathic effects of HIV toward MT-2 T lymphoblasts, and retarded viral replication in CEM T lymphoblasts. Experiments with a deoxycytidine kinase-deficient mutant CEM T cell line showed that this enzyme was necessary for the phosphorylation and anti-HIV activity of the 2-chloro-2',3'-dideoxyadenosine. In contrast, 2',3'-Dideoxyadenosine was phosphorylated by the deoxycytidine kinase-deficient mutant and retained anti-HIV activity in this cell line. Thus, the 2-halo derivatives of 2',3'-Dideoxyadenosine, in contrast to 2',3'-Dideoxyadenosine itself, are not catabolized by T cells. Their anti-HIV and anti-proliferative activities are manifest only in cells expressing deoxycytidine kinase. The in vivo implications of these results for anti-HIV chemotherapy are discussed.
