L-Cysteine, S-(2-boronoethyl)-, hydrochloride (1:1)

Description:

L-Cysteine, S-(2-boronoethyl)-, hydrochloride (1:1) is a boron-containing amino acid derivative that features a cysteine backbone with a boronoethyl substituent. This compound is characterized by its ability to form covalent bonds with biomolecules, particularly through its boron moiety, which can participate in various chemical reactions, including those involving nucleophiles. The presence of the hydrochloride indicates that it is in a salt form, enhancing its solubility in aqueous solutions, which is beneficial for biological applications. L-Cysteine itself is a naturally occurring amino acid known for its role in protein synthesis and as a precursor to glutathione, an important antioxidant. The modification with a boronoethyl group may impart unique properties, such as increased reactivity or specificity in biochemical interactions. This compound is of interest in medicinal chemistry and bioconjugation strategies, particularly in the development of targeted therapies and drug delivery systems. As with many boron-containing compounds, it may also exhibit interesting properties in the context of cancer research and therapeutic applications.
