In an effort to increase the potency and selectivity of earlier identified substrate-based inhibitors of mitochondrial thymidine kinase 2 (TK-2), we now describe the synthesis of new thymidine analogues containing a 4- or 5-substituted 1,2,3-triazol-1-yl substituent at the 3'-position of the 2'-deoxyribofuranosyl ring. These analogues were prepared by Cu- and Ru-catalyzed cycloadditions of 3'-azido-3'-deoxythymidine and the appropriate alkynes, which produced the 1,4- and 1,5-triazoles, respectively. Selected analogues showed nanomolar inhibitory activity for TK-2, while virtually not affecting the TK-1 counterpart. Enzyme kinetics indicated a competitive and uncompetitive inhibition profile against thymidine and the cosubstrate ATP, respectively. This behavior is rationalized by suggesting that the inhibitors occupy the substrate-binding site in a TK-2 ATP complex that maintains the enzyme's active site in a closed conformation through the stabilization of a small lid domain.

The present invention relates to novel HSP27 inhibitors, in particular purine derivatives according to general formula (I) or (II) and phenothiazine derivatives according to formula (V), and to their use as drugs for the selective inhibition of the heat shock protein HSP27 (HSPB1), in particular for use in the treatment of carcinomas or cystic fibrosis, said inhibitors having a particularly advantageous activity in the lower micromolar or sub-micromolar active ingredient concentration range with respect to HSP2.

relies on salvage of nucleosides for DNA synthesis and Up thymidine kinase (UpTK) provides the necessary thymidine nucleotides. The anti-HIV compound 3́-azido-3′-deoxythymidine (AZT) is a good substrate for TK. Methods for a rapid and efficient synthesis of new 3′-α-[1,2,3]triazol-3′-deoxythymidineanalogs from AZT under Huisgen conditions are described. Thirteen 3′-analogues were tested with human cytosolic
致病性支原体小脲原体( Up ) 会引起机会性感染,并依赖于核苷的挽救来进行 DNA 合成,而Up胸苷激酶 ( Up TK) 则提供必需的胸苷核苷酸。抗 HIV 化合物 3́-azido-3'-deoxythymidine (AZT) 是 TK 的良好底物。描述了在胡伊斯根条件下从 AZT 快速有效合成新的 3'-α-[1,2,3]三唑-3'-脱氧胸苷类似物的方法。使用人胞质胸苷激酶 (hTK1) 和Up TK测试了 13 种 3'-类似物。在所有情况下,Up TK 的新类似物均表现出比 hTK1 更高的效率(K m / V最大值) 。尽管如此,hTK1 仍优先被 10 个测试类似物中的 9 个抑制。构建了Up TK 和 hTK1的结构模型并用于解释动力学结果。两种酶的活性位点内的核苷有两种不同的结合模式,其中一种在细菌酶中占主导地位,另一种在 hTK1 中占主导地位。这些结果将有助于抗支原体核苷的未来开发。
