 Use of Cycloleucine


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].

Ki: 600 μM (NMDA)[1][2]
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].
In Vivo Cycloleucine (0.5-4 µg; intracerebroventrical injection) increases time spent in open arms, open arm entries, and extreme arrivals in rats[3]. Animal Model: Male rats bilaterally cannulated into the nucleus accumbens septi (NAS)[3] Dosage: 1 µL of 0.5, 1.0, 2.0, 4 µg/µL Administration: Intracerebroventrical injection Result: Increased time spent in the open arms and extreme arrivals at all doses. Increased open arm entries at the dose of 4 μg.
