  N-Hydroxy-4-(4-chlorophenyl)thiazole-2(3H)-thione as a Photochemical Hydroxyl-radical Source: Photochemistry and Oxidative Damage of DNA (Strand Breaks) and 2′-Deoxyguanosine (8-oxodG Formation)¶

  摘要：

  On irradiation of N-hydroxythiazole-2(3H)-thione 3 at 300 nm, the photoproducts disulfide 4, bisthiazole 5 and thiazole 6 are formed. During this photolysis, hydroxyl radicals are released, which have been detected by spin trapping with 5,5-dimethyl-1-pyrroline N-oxide (DMPO), coupled with electron paramagnetic resonance spectroscopy. In the presence of supercoiled pBR322 DNA, irradiation of thiazolethione 3 induces strand breaks through the photogenerated hydroxyl-radicals, as confirmed by control experiment with the hydroxyl-radical scavenger isopropanol, Singlet oxygen appears not to be Involved, as attested by the lack of a D2O isotope effect. During the photoreaction of thiazolethione 3 in the presence of 2'-deoxyguanosine (dG), the latter is photooxidized (ca 10% conversion after 2 h of irradiation) to the 7,8-dihydro-8-oxo-2'-deoxyguanosine as the main oxidation product. The dG conversion levels off after complete consumption of thiazolethione 3 and is suppressed by the addition of the hydroxyl-radical scavenger 2,6-di-tert-butyleresol or DMPO, Since the photoproducts 4-6 are ineffective as sensitizers for the photooxidation of dG and DNA, the hydroxyl radicals released in the photolysis of thiazolethione 3 are the oxidizing species of DNA and dG, These results suggest that the thiazolethione 3 may serve as a novel and effective photochemical hydroxyl-radical source for photobiological studies.

  N-(alkoxy)pyridine-2(1H)-thiones and N-(alkoxy)thiazole-2(3H)-thiones. Four issues have been addressed and the following conclusions can be drawn: (i) Thiones 1 and 5 exist as O–H acids in the solid state. (ii) According to NMR investigations (1H, 13C), the thione structures should be largely retained in CDCl3, [D6]DMSO, and CD3OD solutions of acids 1, 3–5, as is also the case for pyridinethione salts 2a–h. (iii)

(iii) 吡啶硫酮盐的 O-烷基化与 S-烷基化竞争发生。然而，如果在极性非质子介质中用硬烷基化试剂处理具有大抗衡阳离子（例如 M = NBu4）的硫代异羟肟酸盐，则选择性 O-烷基化是可能的。(iv) 作为硫代异羟肟酸四丁基铵，例如 2f，在环硫异羟肟酸 O-酯的合成中非常有用，我们开发了一种使用相转移条件直接从酸 1 制备 N-（烷氧基）吡啶-2（1H）-硫酮的有效方案（

  4-(p-Chlorophenyl)-3-hydroxythiazole-2(3H)-thione (3) can be prepared in good yields and in useful quantities from p-chloro acetophenone (1). 0-Alkylation of the cyclic thiohydroxamic acid 3 via the respective potassium or the tetraethyl ammonium salts affords the esters 4. A slightly modified procedure allows the conversion of the acid 3 to the mixed anhydrides 5. The esters 4 and the anhydrides 5 are colorless to yellowish crystalline compounds which show a good shelf life. Visible light photolysis of the N-alkoxy derivatives 4e-g and reactive hydrogen donors affords substituted tetrahydrofurans 7 or tetrahydropyrans 8 via an alkoxyl radical pathway.
