  Synthesis, Characterization, and Optimization for in Vivo Delivery of a Nonselective Isopeptidase Inhibitor as New Antineoplastic Agent

  摘要：

  Bis-arylidenecycloalkanones structurally related to the nonselective isopeptidase inhibitor G5 were synthesized and tested for cytotoxic activity against glioblastoma cells. Cytotoxicities correlate well with Hammett s constants for substituted arylidene groups, confirming the proposed inhibition mechanism. A new inhibitor (2c) based on the 4-hydroxycyclohexanone scaffold, which favors apoptosis over necrosis, was selected for further development. 2c inhibited representative deubiquitinases with micromolar IC50, and its proapoptotic activity was studied on several cancer cell lines. Inhibitor 2c was conjugated to PEG via dicarbamate and diester linkers. While the dicarbamate was inactive, the diester (2cPE) behaves like a prodrug and is converted into the active species 2c by secreted esterase activities. Finally, 2cPE was also tested in vivo on A549 lung carcinoma xenografts generated in mice. Intravenous treatment with 2cPE led to a significant reduction in primary tumor growth, without appreciable toxicity to mice.

  An efficient and room-temperature procedure is developed for high yield synthesis of novel α,β-unsaturated derivatives of thiopyran 3 directly from ketone 1 and various aldehydes in the presence of catalytic quantities of TMSNMe2 and MgBr2˙OEt2 under solvent-free conditions. The main advantage of the procedure is that the formation of the undesired bis by-products is minimized. In addition, the procedure
