Biochem/physiol Actions

L-2,4-Diaminobutyric acid (DAB) is a substrate of diaminobutyrate-pyruvate transaminase (EC 2.6.1.46), an enzyme involved in an alternative polyamine biosynthesis pathway in bacteria.
L-2,4-Diaminobutyric acid (DAB, DABA), a non-metabolized amino acid, is useful as a selective GABA uptake inhibitor which may have antitumour activity against hepatoma cells.

Hemophilic arthropathy (HA) typically begins with proliferative synovitis that shares some similarities with inflammatory arthritides, in which the proinflammatory cytokine tumor necrosis factor (TNF)-α has a crucial pathogenetic role. Inappropriate release of TNF-α was shown to contribute to arthropathy development
