Abstract A series of 3,5-disubstitute-4-alkynylisoxazole derivatives were designed and synthesized through palladium(II)-copper(I) catalyzed Sonogashira cross-coupling reaction of an alkynyl moiety and an isoxazole scaffold as novel HSP90 inhibitors. The resultant compounds displayed moderate to potent binding affinity to HSP90 proteins, and also demonstrated good cell growth inhibitory activity against various cancer cell lines (A549, K562, MCF-7, DU145 and Hela). Some compounds (18d, 18e, 19a, 19d, 20c and 20q) show similar or better binding affinity towards HSP90α and HSP90β comparing to NVP-AUY922. In addition, compounds 18e, 19a and 20q exhibited potent inhibitory activity against various human cancer cell lines.

Several chemical fragments have been confirmed as highly efficient cores for the design of Hsp90 inhibitors. Molecular hybridization of potent fragments has been widely used as a rational drug discovery strategy. In this study, a novel class of hybrids of benzofuran, a privileged core from natural products, and 2,4-dihydroxy-5-isopropyl phenyl, an efficient fragment in Hsp90 inhibitors, were designed and synthesized. Subsequent evaluation confirmed they inhibited cell proliferation and regulated the level of client proteins through Hsp90 inhibition. Some of the hybrids can serve as leads to obtain novel chemotypes of Hsp90 inhibitors. The methods reported here may expand the range of known structural types accommodated by the ATP binding site of Hsp90.

Inhibitors of the Hsp90 molecular chaperone are showing considerable promise as potential chemotherapeutic agents for cancer. Here, we describe the structure-based design, synthesis, structure - activity relationships and pharmacokinetics of potent small-molecule inhibitors of Hsp90 based on the 4,5-diarylisoxazole scaffold. Analogues from this series have high affinity for Hsp90, as measured in a fluorescence polarization (FP) competitive binding assay, and are active in cancer cell lines where they inhibit proliferation and exhibit a characteristic profile of depletion of oncogenic proteins and concomitant elevation of Hsp72. Compound 40f (VER-52296/NVP-AUY922) is potent in the Hsp90 FP binding assay (IC50 = 21 nM) and inhibits proliferation of various human cancer cell lines in vitro, with GI50 averaging 9 nM. Compound 40f is retained in tumors in vivo when administered i.p., as evaluated by cassette dosing in tumor-bearing mice. In a human colon cancer xenograft model, 40f inhibits tumor growth by ~50%.
