General description

L-2,4-Diaminobutyric acid dihydrochloride is an unnatural amino acid derivative.

Application

L-2,4-Diaminobutyric acid dihydrochloride is suitable reagent used for the differentiation of β-N-methylamino-L-alanine from the diamino acids by using HPLC-FD, UHPLC-UV, UHPLC-MS, and triple quadrupole tandem mass spectrometry (UHPLC-MS/MS). It is suitable reagent used in the quantification of neurotoxin β-N-methylamino-L-alanine (BMAA) in seafood. It may be used as Internal standard for amino acid analysis

The neurotoxin β-N-methylamino-L-alanine (BMAA) produced naturally by cyanobacteria, diatoms and dinoflagellates can be transferred and accumulated up the food chain, and may be a risk factor for neurodegenerative diseases. This study provides the first systematic screening of BMAA exposure of

Actinoplanes friuliensis produces the lipopeptide antibiotic friulimicin, which is a cyclic peptide with one exocyclic amino acid linked to a branched-chain fatty acid acyl residue. The structural relationship to daptomycin and the excellent antibacterial performance of friulimicin make the antibiotic

Hairpin polyamide-chlorambucil conjugates containing an alpha-diaminobutyric acid (alpha-DABA) turn moiety are compared to their constitutional isomers containing the well-characterized gamma-DABA turn. Although the DNA-binding properties of unconjugated polyamides are similar, the alpha-DABA conjugates display increased alkylation specificity and decreased rate
