Isoxazole is a five-membered heterocycle that is widely used in drug discovery endeavors. Here, we report the design, synthesis, and structural and biological characterization of SS-208, a novel HDAC6-selective inhibitor containing the isoxazole-3-hydroxamate moiety as a zinc-binding group as well as a hydrophobic linker. A crystal structure of the Danio rerio HDAC6/SS-208 complex reveals a bidentate coordination of the active-site zinc ion that differs from the preferred monodentate coordination observed for HDAC6 complexes with phenylhydroxamate-based inhibitors. While SS-208 has minimal effects on the viability of murine SM1 melanoma cells in vitro, it significantly reduced in vivo tumor growth in a murine SM1 syngeneic melanoma mouse model. These findings suggest that the antitumor activity of SS-208 is mainly mediated by immune-related antitumor activity as evidenced by the increased infiltration of CD8+ and NK+ T cells and the enhanced ratio of M1 and M2 macrophages in the tumor microenvironment.
SPHINGOSINE KINASE INHIBITOR AMIDOXIME PRODRUGS

Page/Page column 133; 159, (2017/11/03)
Sphingosine kinases are enzymes that catalyze the biosynthesis of sphingosine-1-phosphate. The invention provides prodrugs of compounds that are effective for inhibition of sphingosine kinase type 1, sphingosine kinase type 2, or both, according to formula (I) as described herein. Formula I compounds are useful in the treatment of a range of diseases wherein increasing the level of sphingosine-1-phosphate in blood is medically indicated. The invention also provides pharmaceutical compositions of Formula I compounds.
