  Synthesis and Evaluation of New Hsp90 Inhibitors Based on a 1,4,5-Trisubstituted 1,2,3-Triazole Scaffold

  摘要：

  Ruthenium catalyzed 1,3-cycloaddition (click chemistry) of an azido moiety installed on dihydroxycumene scaffold with differently substituted aryl propiolates gave a new family of 1,4,5-trisubstituted triazole carboxylic acid derivatives that showed high affinity toward Hsp90 associated with cell proliferation inhibition, both in nanomolar range. The 1,5 arrangement of the resorcinol, the aryl moieties, and the presence of an alkyl (secondary) amide in position 4 of the triazole ring were essential to get high activity. Docking simulations suggested that the triazoles penetrate the Hsp90 ATP binding site. Some 1,4,5-trisubstituted triazole carboxamides induced dramatic depletion of the examined client proteins and a very strong increase in the expression levels of the chaperone Hsp70. In vitro metabolic stability and in vivo preliminary studies on selected compounds have shown promising results comparable to the potent Hsp90 inhibitor NVP-AUY922. One of them, (compound 18, SST0287CL1) was selected for further investigation as the most promising drug candidate.

  光学活性Ki16425的合成及生物学评价

  摘要：

  实现了具有选择性LPA拮抗活性的Ki16425的两个对映异构体的对映体选择性合成。异恶唑核心是通过将氧化腈与炔烃进行1,3-偶极环加成并与旋光性α-苯乙醇链段缩合而构建的，旋光性α-苯乙醇链段是通过对映体选择性还原芳基甲基酮而制得的。Ki16425的两个对映异构体的生物学评估表明（R）-异构体对LPA 1和LPA 3受体具有更高的拮抗活性。

• Exploring in vitro and in vivo Hsp90 inhibitors activity against human protozoan parasites

  日期：2015.2

  A set of compounds, previously selected as potent Hsp90 alpha inhibitors, has been studied on a panel of human parasites. 5-Aryl-3,4-isoxazolediamide derivatives (1) were active against two protozoa, Trypanosoma brucei rhodesiense and Plasmodium falciparum, with a good tolerability toward cytotoxicity on non-malignant L6 rat myoblast cell line, unlike the 1,5-diaryl,4-carboxamides-1,2,3-triazole derivatives (2) which, while showing a single-digit nM range activity against the same protozoa, were also highly cytotoxic on L6 cells. In a subsequent in vivo study, two isoxazolediamide derivatives, 1a and 1b, were very efficacious on the sleeping sickness-causing agent with a clear parasitaemia during treatment. These data, however, showed that not all protozoa are sensitive to Hsp90 inhibitors, as well as not all Hsp90 inhibitors are equally active on parasites. (C) 2014 Elsevier Ltd. All rights reserved.
