This invention is in the field of medicinal chemistry. In particular, the invention relates to a new class of small-molecules having a phenyl-sulfonic amide (or similar) structure which function as agonists of mucolipin 1 (ML1), and their use as therapeutics for the treatment of Duchenne muscular dystrophy (DMD) and related disorders.
Homocysteinase enzymes are disclosed which have sufficient specificity for homocysteine, as compared to cysteine that hydrogen sulfide can be used as a measure of homocysteine in a biological fluid even in the presence of substantial amounts of cysteine, exceeding the level of homocysteine. The enzyme of desired specificity can be readily prepared by mutation and screening of naturally occurring homocysteinases or by constructing chimeric forms. Also disclosed is a method of identify homocysteinases of the desired specificity with respect to homocysteine and cysteine, as well as an improved method to assay for hydrogen sulfide by employing a fluorometric readout of a chromophore generated from said hydrogen sulfide. Also included in the scope of the invention is a method to assess the level of cysteine and homocysteine in the same sample.
A method to determine a total cysteine in biological fluids utilizes similarly treated portions of the fluid with a homocysteinase and a non-specific desulfurase.

An I(III)-catalyzed oxidative cyclization reaction using selectfluor as the oxidant was developed that converts ortho-substituted anilines to benzimidazoles. The mild reaction requires as little as 0.5 mol % of iodobenzene, and its scope is broad: electron-withdrawing or electron-releasing groups on the aniline portion are tolerated, and cyclic or acyclic N-alkylamines are permitted as ortho-substituents

A series of 2 '-aminoanilides have been identified which exhibit potent and selective inhibitory activity against the cFMS tyrosine kinase. Initial SAR studies within this series are described which examine aroyl and amino group substitutions, as well as the introduction of hydrophilic substituents on the benzene core. Compound 47 inhibits the isolated enzyme (IC50 = 0.027 mu M) and blocks CSF-1-induced proliferation of bone marrow-derived macrophages (IC50 = 0.11 mu M) and as such, serves as a lead candidate for further optimization studies.
