Synthesis and evaluation of Hsp90 inhibitors that contain the 1,4-naphthoquinone scaffold
摘要:
High-throughput screening of a library of diverse molecules has identified the 1,4-naphthoquinone scaffold as a new class of Hsp90 inhibitors. The synthesis and evaluation of a rationally-designed series of analogues containing the naphthoquinone core scaffold has provided key structure-activity relationships for these compounds. The most active inhibitors exhibited potent in vitro activity with low micromolar IC50 values in anti-proliferation and Her2 degradation assays. In addition, 3g, 12, and 13a induced the degradation of oncogenic Hsp90 client proteins, a hallmark of Hsp90 inhibition. The identification of these naphthoquinones as Hsp90 inhibitors provides a new scaffold upon which improved Hsp90 inhibitors can be developed. (C) 2008 Elsevier Ltd. All rights reserved.

A novel synthetic approach to amidoquinones by the reaction of naphthoquinones with hydroxamicacids under basic conditions was developed. The reaction is mild and operationally simple, and it affords high yields of amidoquinones. With this new method, a novel, very strong HDAC6 inhibitor, which showed high toxicity to AML cells, was successfully synthesized.
Provided herein are compounds of the formula (IV) as well as pharmaceutically acceptable salts thereof, wherein the substituents are as those disclosed in the specification. These compounds, and the pharmaceutical compositions containing them, are useful as MITF inhibitors, MITF pathway inhibitors and for the treatment of cancer.

Selective C vs N-arylation of 2-aminonaphthoquinone was achieved using different transition metal salts and arylboronic acids. Mn(OAc)(3)center dot 2H(2)O provided C-arylated product whereas NiCl2 center dot 6H(2)O and Cu (OAc)(2)center dot H2O provided N-mono arylated and N,N-diarylated products respectively. Usefulness of the C and N arylated product was demonstrated by converting it into benzocarbazoledione. (C) 2017 Elsevier Ltd. All rights reserved.
