Application
HMP-alkyne is a probe that can be used to photochemically label tryptophans. A method was developed using cysteine-reactive compounds including this one to allow for unbiased analysis of proteomic data in quantitative applications (Zanon et al. 2021). The method uses light or heavy labeling with the isotopically labelled desthiobiotin azide (isoDTB) tag for mass spectrometry analysis (Zanon et al. 2020). Analysis then uses the isotopic tandem orthogonal proteolysis activity-based protein profiling (isoTOP-ABPP) workflow (Weerapana et al. 2010, Backus et al. 2016)

We report herein comprehensive investigations of alkylation/sulfur exchange reactions of sulfur-containing substrates including nucleosides such as s2U, m5s2U, s4U, s2A and s2T-incorporated DNA enable by comprehensive screenings of the reagents (2a-2h). It has been proven that iodoacetamide (2a) displays the

Unbiased binding assays involving small-molecule microarrays were used to identify compounds that display unique patterns of selectivity among members of the zinc-dependent histone deacetylase family of enzymes. A novel, hydroxyquinoline-containing compound, BRD4354, was shown to preferentially inhibit activity of HDAC5
