Selective Inhibitors of Human Liver Carboxylesterase Based on a β-Lapachone Scaffold: Novel Reagents for Reaction Profiling

Carboxylesterases (CEs) are ubiquitous enzymes that are responsible for the metabolism of xenobiotics, including drugs such as irinotecan and oseltamivir. Inhibition of CEs significantly modulates the efficacy of such agents. We report here that β-lapachone is a potent, reversible CE inhibitor with Ki values in the nanomolar range. A series of amino and phenoxy analogues have been synthesized, and although the former are very poor inhibitors, the latter compounds are highly effective in modulating CE activity. Our data demonstrate that tautomerism of the amino derivatives to the imino forms likely accounts for their loss in biological activity. A series of N-methylated amino derivatives, which are unable to undergo such tautomerism, were equal in potency to the phenoxy analogues and demonstrated selectivity for the liver enzyme hCE1. These specific inhibitors, which are active in cell culture models, will be exceptionally useful reagents for reaction profiling of esterified drugs in complex biological samples.

HEAT SHOCK PROTEIN 90 INHIBITORS, METHODS OF PREPARING SAME, AND METHODS FOR THEIR USE

Novel classes of molecular chaperone Heat shock protein 90 (Hsp90) inhibitors are disclosed. These compounds are useful in treating and preventing cancer and other Hsp90-related diseases and conditions, such as inflammation and neurodegenerative disorders. Methods of treating and preventing cancer and other Hsp90 related diseases and conditions are disclosed that include administering to the subject a therapeutically effective amount of an Hsp90 inhibitor. Methods of preparing the novel Hsp90 inhibitors are also provided.

The Effect of Metal Chelate Complexation on the Reactivity and Absorption Spectra of 1,2-Naphthoquinones: New Types of Near-infrared-absorbing Metal Complex Dyes

The reaction of sodium 1,2-naphthoquinone-4-sulphonate with various arylamines and 1,1-bisethylene were effectively promoted by nickel(II) ion to give 4-aminated, 4-arylated, and 4-vinylated 1,2-naphthoquinones in good yield.The f
