Applicazioni
Methyl (4-bromobenzoyl)-L-cysteinate is a chemoselective thiol probe for detection of electrophilic metabolites. As it is often difficult to isolate low-abundance natural products from extracts, metabolities with bioactivity or therapeutic potential may be missed. Castro-Falcón, et al developed a reactivity-guided approach using thiolate probes to discover electrophilic natural products - a cysteine-based probe and thiophenol-based probe. Both consist of
Complementarily, a thiophenol probe (cat# 125237) with a chlorine MS tag and phenyl chloride UV tag labeled epoxide-based natural products. These probes can be used in diverse extracts (bacterial, fungal, plant) to chemically faciliate access to high-value metabolites.
- A chemoselective reagent for covalent reactivity with a pharmacophore,
- A conspicuous UV/VIS or mass spectrometric (MS) tag,
- A linker between the tag and reagent. Methyl (4-bromobenzoyl)-L-cysteinate contains a bromine MS tag and phenyl bromide UV tag that was demonstrated to chemoselectively label enone-, β-lactam-, and β-lactone-based natural products.

To date, 16 members of the ammosamide family of natural products have been discovered, and except for ammosamide D each of these metabolites is characterized by an unusual chlorinated pyrrolo[4,3,2-de]quinoline skeleton. Several ammosamides have been shown to inhibit quinone reductase

Using a novel chemistry-based assay for identifying electrophilic natural products in unprocessed extracts, we identified the PI3-kinase/mTOR dual inhibitor neolymphostin A from Salinispora arenicola CNY-486. The method further showed that the vinylogous ester substituent on the neolymphostin core was the
