  Novel selective human mitochondrial kinase inhibitors: Design, synthesis and enzymatic activity

  摘要：

  Selective and effective TK2 inhibitors can be obtained by introduction of bulky lipophilic chains (acyl or alkyl entities) at the 2' position of araT and BVaraU, nucleoside analogues naturally endowed with a low TK2 affinity. These derivatives showed a competitive inhibitory activity against TK2 in micromolar range. BVaraU nucleoside analogues, modified on the 2'-O-acyl chain with a terminal N-Boc amino-group, conserved or increased the inhibitory activity against TK2 (71 and 7m IC50: 6.4 and 3.8 mu M, respectively). The substitution of an ester for a carboxamide moiety at the 2' position of araT afforded a consistent reduction of the inhibitory activity (25, IC50: 480 mu M). On the contrary, modifications at 2'-OH position of araC and araG, have provided inactive derivatives against TK2 and dGK, respectively. The biological activity of a representative compound, 2'-O-decanoyl-BVaraU, was also investigated in normal human fibroblasts and was found to impair mitochondrial function due to TK2 inhibition.

  We developed a new protecting group, the cyclic sulfite for the protection of the 3′,5′-dihydroxy group of nucleosides. Seven cyclic sulfites, 4a–c, 5a–b, and 6a–b were prepared in high yields from the corresponding xylo-uridines 1 and 2, and xylo-adenosines 3 with thionyl chloride, respectively. Synthesis of the puromycin intermediate 8 was carried out by deprotection of the sulfite moiety through
