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.
