  Adenosine Kinase Inhibitors. 3. Synthesis, SAR, and Antiinflammatory Activity of a Series of l-Lyxofuranosyl Nucleosides

  摘要：

  Chronic inflammatory diseases, such as arthritis and rheumatoid arthritis, remain major health problems worldwide. We previously demonstrated that adenosine kinase inhibitors (AKIs) exhibit antiinflammatory effects by inhibiting TNF-alpha production, neutrophil accumulation, and edema formation. Although adenosine receptor agonists produce similar effects, AKIs showed the antiinflammatory activity without the cardiovascular side effects that prevented the development of adenosine receptor specific agonists. However, previously described potent AKIs, such as 5-iodotubercidin, are nucleosides which have the potential to undergo in vivo 5'-O-phosphorylation and therefore produce cytotoxicity. In an effort to eliminate toxicities produced by phosphorylated nucleosides, L-lyxofuranosyl analogues of tubercidin were tested as potential AKIs since the opposite stereochemical. orientation of the CH2OH was expected to eliminate intracellular phosphorylation. Described herein are the discovery of a new series of AKIs based on alpha-L-lyxofuranosyl. nucleosides, their SAR, as well as the antiinflammatory activity of the lead compound GP790 (IC50 = 0.47 nM, 47% inhibition of paw swelling at 10 mg/kg in rat carrageenan paw edema model). In addition, a study showing that in the skin lesion model the antiinflammatory activity is reversed by an A2 selective adenosine receptor antagonist 3,7-dimethyl-1-propylxanthine (DMPX) is also described.

  5'-carboxaldehyde analogues by Moffatt oxidation (dimethyl sulfoxide/dicyclohexylcarbodiimide/dichloroacetic acid) or with the Dess-Martin periodinane reagent. Hydrolysis of a 5'-fluoro-5'-S-methyl-5'-thio (alpha-fluoro thioether) arabinosyl derivative also gave the 5'-carboxaldehyde. Treatment of 5'-carboxaldehydes with hydroxylamine [or O-(methyl, ethyl, and benzyl)hydroxylamine] hydrochloride gave

  通过Moffatt氧化（二甲基亚砜/二环己基碳二亚胺/二氯乙酸）或用Dess-Martin高碘烷试剂将选择性保护的腺嘌呤核苷转化为5'-甲醛醛类似物。5'-氟-5'-S-甲基-5'-硫代（α-氟硫醚）阿拉伯糖基衍生物的水解也得到5'-甲醛。用羟胺[或O-（甲基，乙基和苄基）羟胺]盐酸盐处理5'-甲醛，得到E / Z肟。用三氟乙酸水溶液和丙酮处理纯化的肟可实现反式肟化反应，从而提供干净的5'-甲醛样品。腺苷（Ado）-5'-甲醛及其4'-末端是S-腺苷-L-高半胱氨酸（AdoHcy）水解酶的有效抑制剂。它们与酶有效结合并在C3'处发生氧化 得到3'-酮类似物，同时降低NAD +辅因子，得到无活性的，紧密结合的NADH-酶复合物（I型辅因子耗竭抑制）。用含有核糖顺式2'，3'-乙二醇的5'-羧醛观察到了有效的I型抑制作用。它们的肟衍生物是“前抑制剂”，它们经过酶催化水解后在活性位点释放抑制剂。
