Cycloleucine is a specific inhibitor of S-adenosyl-methionine mediated methylation. Cycloleucine is antagonist of NMDA receptor associated glycine receptor, with a Ki of 600 μM. Cycloleucine is also a competitive inhibitor of ATP: L-methionine-S-adenosyl transferase in vitro. Cycloleucine has anxiolytic and cytostatic effects.

Description

Cycloleucine is a specific inhibitor of S-adenosyl-methionine mediated methylation. Cycloleucine is antagonist of NMDA receptor associated glycine receptor, with a Ki of 600 μM. Cycloleucine is also a competitive inhibitor of ATP: L-methionine-S-adenosyl transferase in vitro. Cycloleucine has anxiolytic and cytostatic effects[1][2][3][4].

NMDA Receptor

 

In Vitro

Cycloleucine (4-40 mM; 3 h) blocks internal methylation of viral RNA in B77 transformed chick embryo fibroblasts[5].
? Cycloleucine (40 mM; 24 h) blocks the formation of both m6A and the penultimate Gm in B77 38S RNA subunits by greater than 90%[5].
? Cytostatic (10 μg/mL) inhibits the viability human KB and mouse L1210s leukemia cell lines[5].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Cycloleucine (0.5-4 μg; intracerebroventrical injection) increases time spent in open arms, open arm entries, and extreme arrivals in rats[3].? Cycloleucine reduces thymus and spleen weights in Semliki Forest virus (SFV) strain A7(74) infected and control mice[6].

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.
