Abstract
3'-Azido-3',5-dideoxythymidine 5'-phosphonate and 3',5'-dideoxy-5'-difluoromethylenethymidine 5'-phosphonate were prepared by multistep syntheses. The nucleoside 5'-phosphonates were converted to their triphosphates and triphosphate mimics (P3Ms) containing beta,gamma-difluoromethylene, beta,gamma-dichloromethylene, or beta,gamma-imodo by condensation with pyrophosphate or pyrophosphate mimics, respectively. Inhibition of HIV-1 reverse transcriptase by the nucleoside P3Ms is briefly discussed.

Abstract
Aryl nucleoside 5'-H-phosphonates 4 bearing AZT or 2',3'-dideoxyuridine moieties were subjected to reaction with various aromatic aldehydes to produce nucleoside 5'-alpha-hydroxyphosphonate derivatives 2 as potential anti-HIV agents. Stability of the title compounds in cell culture media was investigated and three distinct decomposition pathways were identified. The anti-HIV activity of hydroxyphosphonates 2 correlates well with the type and extent of their chemical or enzymatic degradation in culture medium (RPMI 1640 containing 10% FBS), suggesting that aryl nucleoside 5'-hydroxyphosphonates 2 act as depot forms of the parent antiviral nucleosides.

Abstract
The kinetic parameters of adenosine deaminase such as Km and Ki were determined in the absence and presence of adenine derivatives (R1-R24) in sodium phosphate buffer (50 mM; pH 7.5) solution at 27 degrees C. These kinetic parameters were used for QSAR analysis. As such, we found some theoretical descriptors to which the binding affinity of adenosine deaminase (ADA) towards several adenine nucleosides as inhibitors is correlated. QSAR analysis has revealed that binding affinity of the adenine nucleosides upon interaction with ADA depends on the molecular volume, dipole moment of the molecule, electric charge around the N1 atom, and the highest of positive charge for the related molecules.

Abstract
Synthesis of adenine derivative of triphosphono-gamma-(Z)-ethylidene-2,3-dimethoxybutenolide 4 was accomplished by treatment of phosphonate 3 with 5-phosphoribosyl 1-pyrophosphate in the presence of 5-phosphoribosyl 1-pyrophosphate synthetase. It was found that triphosphonate 4 functions as an irreversible stoichiometric inactivator of the Escherichia coli ribonucleoside diphosphate reductase (RDPR). Triphosphonate 4 exhibited potent inhibitory activity against murine leukemias (L1210 and P388), breast carcinoma (MCF7), and human T-lymphoblasts (Molt4/C8 and CEM/0) cell lines. Paclitaxel ester derivatives of adenine-containing triphosphono-gamma-(Z)-ethylidene-2,3-dimethoxybutenolide 8-10 were also synthesized. Like triphosphonate 4, compound 8 exhibited inhibitory property toward RDPR. It also induced microtubule assembly similar to paclitaxel (5). The structure of the chlorodiester linker in 8 was found to account for this dual property. After treatment of MCF7 cells with compounds 4, 5, and 8, fluorescence microscope examination demonstrated the presence of nucleus shrinkage or segmentation. Bifunctional prodrug 8 exhibited higher lipophilicity than 4 and higher water-solubility than 5. Pro-dual-drug 8 exhibited more pronounced anticancer activity relative to that of the triphosphonate 4 and paclitaxel (5). In contrast, compound 9, resulting from the linkage of triphosphonate 4 and paclitaxel (5) through a diester unit, was only found to function as a highly water-soluble prodrug for paclitaxel (5). It induced microtubule assembly in vitro, but did not show inhibitory property toward RDPR. On the other hand, compound 10, an aggregate of triphosphonate 4 and paclitaxel (5), neither functioned as an inhibitor of RDPR nor exhibited microtubule assembly stimulating activity in vitro.

Abstract
In order to overcome restrictions imposed by activation (phosphorylation) mechanism of antiviral and antitumor nucleoside analogues several prodrug approaches have been designed. Lipophilic pronucleotides are capable of intracellular delivery of monophosphates of nucleoside analogues, thus circumventing the limitations of enzymic phosphorylation. One of the successful approaches employs lipophilic amino acid ester (alanine) phenyl phosphoramidates as pronucleotides. This approach was applied to AIDS drugs such as AZT, d4T and related analogues but also to nonclassical nucleoside analogues based on allenic and methylenecyclopropane structure. Antiviral effects of the parent analogues were in many cases increased by conversion to phenyl phosphoralaninate (PPA) pronucleotides. Although cytotoxicity increase frequently accompanies antiviral effects of these pronucleotides, a favorable selectivity index can be obtained by manipulation of the parent structure as shown, e.g., for 2,6-diaminopurine methylenecyclopropane pronucleotide 15c. A lack of in vivo toxicity was demonstrated for 2-amino-6-methoxypurine methylenecyclopropane pronucleotide 15e in mice. The PPA pronucleotides can overcome deficiency of phosphorylating enzymes and offer favorable cross-resistance patterns when compared with other antiviral drugs.

Abstract
A novel strategy was developed for the synthesis of N(7)-purine acyclic nucleosides 9 and 14. The key step involved the reaction between [2-(p-methoxyphenyloxy)ethoxy]methyl chloride and N(9)-tritylated nucleobases 6 or 11 followed by concomitant self-detritylation. N(7)-Guanine acyclic nucleoside 9 exhibited antiviral activity, but was phosphorylated by both HSV and Vero cell thymidine kinases. Thus, it showed more potent cellular toxicity than acyclovir (2). N(7)-Adenine acyclic nucleoside 14 was found to be an excellent antiviral agent as well as a good inhibitor of calf mucosal adenosine deaminase. This inhibitory property allows for a greater expression of antiviral activity of antiviral agents, such as N(9)-adenine acyclic nucleoside 1 and ara-A (3). Compound 14 was phosphorylated neither by herpes simplex virus (HSV) thymidine kinase nor by Vero cell thymidine kinase, yet it enhanced the rate constant for the monophosphorylation of acyclovir (2) by HSV thymidine kinase. Consequently, the combination of acyclovir (2) and 14 exhibited greater antiviral activity than acyclovir alone. 7-[2-(Phosphonomethoxy)ethyl]adenine (20) was also synthesized. The key step involved the reaction of 9-(2-cyanoethyl)adenine (15) with methyl iodoacetate in the presence of lithium 2,2,6,6-tetramethylpiperidine in THF. Unlike 9-[2-(phosphonomethoxy)ethyl]adenine (PMEA, 4), the N(7)-isomer 20 was not phosphorylated effectively by 5-phosphoribosyl 1-pyrophosphate synthetase (PRPP synthetase). Thus, it did not exhibit pronounced antiviral activity. Dinucleotide 5'-monophosphate 24 and its butenolide ester 25 were also synthesized. Compound 24 showed substrate activity toward PRPP synthetase and exhibited notable activity against DNA viruses. The antiviral activity of the ester derivative 25 was found to be higher than that of the parent molecule 24. Dinucleotide 5'-monophosphate 24 is susceptible to degradation by snake venom and spleen phosphodiesterases. However, its respective butenolide ester derivative 25 was completely resistant to snake venom and spleen enzymes. Butenolide ester derivatives 28 and 29 were also synthesized and exhibited notable anti-DNA virus and anti-retrovirus activity in vitro. Compounds 2, 4, 9, 14, 20, 24, 25, and 28 were also evaluated for their inhibitory effect on HSV-1-induced mortality in NMRI mice. N(7)-adenine acyclic nucleoside 14 [LD(50) (intraperitoneal, ip) 950 mg/kg], nucleotide-containing butenolide 25 [LD(50) (ip) 675 mg/kg], and butenolide 28 [LD(50) (ip) 710 mg/kg] were found to be potent anti-HSV-1 agents in vivo. In addition, butenolide 28 efficiently decreased tumor formation induced by Moloney murine sarcoma virus (MSV) in NMRI mice while significantly increasing the survival time of MSV-infected mice.

Abstract
Lipophilic phosphodiester amidates 2a, 2b, 4a, 4b, and 6 derived from anti-HIV agent adenallene 1a, 3a, inactive hypoxallene 1b, 3b, and 9-(4-hydroxy-2-butyn-1-yl)adenine (5) were synthesized and studied as inhibitors of HIV-1 in ATH8 cell system. All phosphodiester amidates were more biologically active than their parent nonphosphorylated compounds. Analogues 2a and 4a derived from (+/-)-adenallene 1a and (R)-enantiomer 3a are effective anti-HIV agents with EC50 approximately 0.88 and 0.21 microM, respectively. Both analogues are 16 and 28 times more effective than parent compounds 1a and 3a, respectively. Some anti-HIV activity of hypoxallene derivatives 2b and 4b was noted in the range of 0.1-10 microM but the dose-response relationship was poor. Phosphodiester amidate analogue 6 also exhibited anti-HIV activity in the range of 0.1-100 microM, but this effect was accompanied by cytotoxicity. Hydrolytic studies performed at pH 9.8 and with pig liver esterase at pH 7.4 have shown that analogue 2a gives adenallene 4'-phosphoralaninate (10a) as the major product. These results can be interpreted in terms of initial hydrolysis of phosphodiester amidates 2a, 2b, 4a, 4b, and 6 catalyzed by intracellular esterase(s) to give stable phosphomonoester amidate intermediates with a free carboxyl group. The results obtained with hypoxallene phosphoramidates 2b and 4b indicate that the aminosuccinate-fumarate enzyme system responsible for activation of AIDS drug ddIno (didanosine, Videx) can also, albeit less efficiently, activate hypoxallene 4'-phosphate (9b) and the respective (R)-enantiomer released inside the HIV-infected cells.
