Tropolones As Lead-Like Natural Products: The Development of Potent and Selective Histone Deacetylase Inhibitors
摘要:
Natural products have long been recognized as a rich source of potent therapeutics but further development is often limited by high structural complexity and high molecular weight. In contrast, at the core of the thujaplicins is a lead-like tropolone scaffold characterized by relatively low molecular weight, ample sites for diversification, and metal-binding functionality poised for targeting a range of metalloenzyme drug targets. Here, we describe the development of this underutilized scaffold for the discovery of tropolone derivatives that function as isozyme-selective inhibitors of the validated anticancer drug target, histone deacetylase (HDAC). Several monosubstituted tropolones display remarkable levels of selectivity for HDAC2 and potently inhibit the growth of T-cell lymphocyte cell lines. The tropolones represent a new chemotype of isozyme-selective HDAC inhibitors.

A direct route to analogs of the naturally occurring tropolone β-thujaplicin has been developed in just four steps from furan. Using this method, a series of derivatives were synthesized and evaluated. Several of these compounds demonstrated very high levels of potency against bacterial and fungal pathogens with good selectivity over mammalian cells.
