Description

L-Cycloserine ((S)-4-Amino-3-isoxazolidone) is an oral inhibitor of the enzyme gamma-aminobutyric acid (GABA) transaminase (GABA-t) and branched-chain transaminases in Mycobacterium tuberculosis. L-Cycloserine has anticonvulsant properties and inhibits the synthesis of neurotensin in mouse brains[1][2][3][4].

In Vivo

L-Cycloserine (25-50 mg/kg, intraperitoneal injection, single dose) has anticonvulsant effects in mice[2].
L-Cycloserine (30-100 mg/kg, orally or via intraperitoneal injection, twice daily for 5 days) enhances the inhibitory effect on GABA-T activity in mice and boosts its anticonvulsant effects[3].
L-Cycloserine (100-150 mg/kg, subcutaneous or intraperitoneal injection, once daily for 1 week) can reduce the brain content of gangliosides by 28% when injected subcutaneously, with no effect on the content of neurogangliosides; intraperitoneal injection leads to decreased levels of gangliosides and cerebrosides[4].
L-Cycloserine (100 mg/kg, subcutaneous or intraperitoneal injection, single dose) affects the level of inhibition of 3-keto-dihydrosphingosine synthase depending on the method of injection[4].

Animal Model: Close-crossed epileptic mice (DBA/2J), normal CBNCa mice[2]
Dosage: 25, 50 mg/kg; single dose
Administration: Intraperitoneal injection (i.p.)
Result: Protected mice from seizures three hours later, and the effects gradually weakened thereafter, with lower concentrations of glutamate and aspartate in the hypothalamus decreasing and γ-aminobutyric acid increasing.
Animal Model: DAB/2mice induced by 3-MPA[3]
Dosage: 100 mg/kg; twice a day; 5 days
30 mg/kg; single dose
Administration: Oral; Intraperitoneal injection (i.p.)
Result: Enhanced inhibition of GABA-T activity protected mice from 3-mercaptopropionic acid (3-MPA)-induced tonic seizures, and motor performance deficits decreased over time.
Animal Model: Male Swiss mice[4]
Dosage: 100 mg/kg; single dose
Administration: Subcutaneous injection (s.c.); Intraperitoneal injection (i.p.)
Result: Showed that 2 hours after intraperitoneal injection, the synthase activity was found to be inhibited by 80%, and subcutaneous injection of L-cycloserine had no significant inhibitory effect on the synthase within 2-48 hours.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
