  SYNTHESIS OF 1-(2-DEOXY-β-D-RIBOFURANOSYL)-2,4-DIFLUORO-5-SUBSTITUTED-BENZENES^*: “THYMINE REPLACEMENT” ANALOGS OF THYMIDINE FOR EVALUATION AS ANTICANCER AND ANTIVIRAL AGENTS

  摘要：

  A group of unnatural 1-(2-deoxy-beta -D-ribofuranosyl)-2,4-difluorbenzenes having a variety of C-5 two-carbon substituents II-CC-X, X = I, Br; -Cr=CH; (E)- CH=CH-X, X = I, Br; - CH=CH(2); - CH(2)CI(1); -CH(N(3)) CH(2)Br], designed as nucleoside mimics, were synthesized for evaluation as anticancer and antiviral agents. The 5-substituted (E)-CH=CH-I and -CH(2)CH(3) compounds exhibited negligible cytotoxicity in a MTT assay (CC(50) = 10(-3) to 10(-4)M range), relative to thymidine (CC(50) 10-3 to 10(-5) M range), against a variety of cancer cell lines. In contrast, the C-5 substituted -C=C-I and -CH(N(3))CH(2)Br compounds were more cytotoxic (CC(50) = 10(-5) to 10(-6) M range). The -C=C-I and -CH(2)CH(3) compounds exhibited similar cytotoxicity against non-transfected (KBALB, 143B) and HSV-1 TK(+) gene transfected (KBALB STK, 143B-LTK) cancer cell lines expressing the herpes simplex virus type 1 (HSV-1) thymidine kinase gene (TK(+)). This observation indicates that expression of the viral TK enzyme did not provide a gene therapeutic effect. The parent group of 5-substituted compounds, that were evaluated using a wide variety of antiviral assay systems [HSV-1, HSV-2, varicella-zoster virus (VZV), vaccinia virus, vesicular stomatitis, cytomegalovirus (CMV), and human immunodeficiency (HIV-1, HIV-2) viruses], showed that this class of unnatural C-aryl nucleoside mimics are inactive and/or weakly active antiviral agents.

  The thymidine mimics isocarbostyril nucleosides and difluorophenyl nucleosides were tested as deoxynucleoside kinase substrates using recombinant human cytosolic thymidine kinase (TK1) and deoxycytidine kinase (dCK), and mitochondrial thymidine kinase (TK2) and deoxyguanosine kinase (dGK). The isocarbostyril nucleoside compound 1-(2-deoxy-beta-D-ribofuranosyl)-isocarbostyril (EN1) was a poor substrate with all the enzymes. The phosphorylation rates of EN1 with TKI and TK2 were <1% relative to Thd, where as the phosphorylation rates for EN1 were 1.4% and 1.1% with dCK and dGK relative to dCyd and dGuo, respectively. The analogue 1-(2-deoxy-beta-D-ribofuranosyl)-7-iodoisocarbostyril (EN2) showed poor relative-phosphorylation efficiencies (k(cat)/Kappa(m).) with both TK1 and dGK, but not with TK2. The k(cat)/Kappa(m) value for EN2 with TK2 was 12.6% relative to that for Thd. Of the difluorophenyl nucleosides, 5-(1'-(2'-deoxy-beta-D-ribofuranosyl))-2,4-difluorotoluene (JW1) and 1-(1'-(2'-deoxy-beta-D-ribofuranosyl))-2,4-difluoro-5-iodobenzene (JW2) were substrates for TK1 with phosphorylation efficiencies of about 5% relative to that for Thd. Both analogues were considerably more efficient substrates for TK2, with k(cat)/Kappa(m). values of 45% relative to that for Thd. 2,5-Difluoro-4-[1-(2-deoxy-beta-L-ribofuranosyl)]-aniline (JW5), a L-nucleoside mimic, was phosphorylated up to 15% as efficiently as deoxycytidine by dCK. These data provide a possible explanation for the previously reported lack of cytotoxicity of the isocarbostyril- and difluorophenyl nucleosides, but potential mitochondrial effects of EN2, JW1 and JW2 should be further investigated.

  The title compound, C19H18F2IO6P, prepared as a potential antiviral and anticancer agent from 3-methylsalicylchlorophosphane and 1-(2,4-difluoro-5-iodophenyl)-2-deoxy-beta-D-ribofuranose, is one of a 1: mixture of two diastereomers. The diastereomers differ in their configuration, S or R, at the asymmetric phosphorus center. X-Ray crystallographic analysis of the title compound has determined the absolute configuration at the asymmetric P center to be S.

  A group of unnatural 1-(2-deoxy-beta-D-ribofuranosyl)-2,4-difluorobenzenes possessing a 5-I or 5-CF3 substituent, that were originally designed as thymidine mimics, were coupled via their 5'-OH group to a cyclosaligenyl (cycloSal) ring system having a variety of C-3 substituents (Me, OMe, H). The 5'-O-cycloSal-pronucleotide concept was designed to effect a thymidine kinase-bypass, thereby providing a method for the intracellular delivery and generation of the 5'-O-monophosphate for nucleosides that are poorly phosphorylated. The 5'-O-cycloSal pronucleotide phosphotriesters synthesized in this study were obtained as a 1:1 mixture of two diastereomers that differ in configuration (S(P) or R(P)) at the asymmetric phosphorous center. The (S(P))- and (R(P))-diastereomers for the 5'-O-3-methylcycloSal- and 5'-O-3-methoxycycloSal derivatives of 1-(2-deoxy-beta-D-ribofuranosyl)-2,4-difluoro-5-iodobenzene were separated by silica gel flash column chromatography. This class of cycloSal pronucleotide compounds generally exhibited weak cytotoxic activities in a MTT assay (CC50 values in the 10(-3) to 10(-4) M range), against a number of cancer cell lines (143B, 143B-LTK, EMT-6, Hela, 293), except for cyclosaligenyl-5'-O-[1'-(2,4-difluoro-5-iodophenyl)-2'-deoxy-beta-D-ribofuranosyl]phosphate that was more potent (CC50 values in the 10(-5) to 10(-6) M range), than the reference drug 5-iodo-2'-deoxyuridine (IUDR) which showed CC50 values in the 10(-3) to 10(-5) M range.

  1-(2-Deoxy-beta-D-ribofuranosyl)-2,4-difluoro-5-iodobenzene (dRFIB) is a Putative bioisostere of iododeoxyuridine (IUdR). The advantages of dRFIB over IUdR for in vivo studies include resistance to both phosphorolytic cleavage of the nucleoside bond and de-iodination. dRFIB was radioiodinated (dRF(123/125)IB) by copper-catalyzed exchange using commercial sodium [I-123/125]iodide. The in vivo biodistribution of dRF[I-125]IB in BALBc mice and imaging of dRF[I-123]IB in Sprague-Dawley rats are reported. In vivo data for rats show rapid clearance of radioactivity from blood (> 95% LD in 15 minutes), extensive excretion in urine (56%ID/24 hours), concentration in the hepatobiliary-small intestine system and very little fecal excretion (similar to 3% ID/24 hours). Pharmacokinetic data for dRF[I-125]IB (i.v. 48.7 ug/kg) in rats (t(1/2)[h] = 0.51 +/- 0.14, AUC(inf)[mu g.min/mL] = 3.7 +/- 0.4, Cl[L/kg/h] = 0.75 +/- 0.12, Vss[L/kg] = 0.96 +/- 0.18) corfirm. previously reported dose-dependent pharmacokinetics. Scintigraphic images of rats dosed with dRF[I-123]I were compatible with rapid soft-tissue clearance and extensive accumulation of radioactivity in bladder/urine and liver/small intestine. In tumor bearing mice, thyroid and stomach radioactivity was indicative of moderate deiodination. An unidentified polar radioactive metabolite was detected in serum.
