4-N-Hydroxy-L-2,4-diaminobutyric acid. A strong inhibitor of glutamine synthetase
摘要:
Analogues of glutamic acid were synthesized and evaluated for their inhibitory activity toward glutamine synthetase (EC 6.3.1.2; GS). The title compound, 4-N-hydroxy-L-2,4-diaminobutyric acid (NH-DABA), showed a potent inhibitory activity against GS from both sheep brain and soybean. The inhibition is competitive with respect to glutamic acid and the Ki values of sheep brain GS and soybean GS for NH-DABA are 0.007 mmol and 0.021 mmol, respectively. The activity of inhibition is comparable to those of L-methionine sulfoximine and 2-amino-4-(hydroxymethyl-phosphinyl)butyric acid (phosphinothricin).

The individualenantiomers of the glycineantagonistHA-966 (1) have been obtained by resolution via the bis-Boc-L-Phe (Boc = t-butoxycarbonyl) derivatives (2a and 2b) and by synthesis from D- and L-methionine.
甘氨酸拮抗剂HA-966(1)的单个对映体是通过bis-Boc- L -Phe(Boc =叔丁氧羰基)衍生物(2a和2b)拆分并由D-和L-蛋氨酸合成而获得的。
