LM22B-10

SKU: orb1223143

Description

LM22B-10 is a TrkB and TrkC agonist. LM22B-10 exhibits neurotrophic activity (EC50 = 200-300 nM). LM22B-10 improves survival and increases neurite outgrowth in hippocampal cells in vitro. LM22B-10 increased cell survival and strongly accelerated neurite outgrowth, superseding the effects of brain-derived neurotrophic factor (BDNF), NT-3 or the two combined.

Bioactivity

• In Vivo:
  LM22B-10 (0.5 mg/kg) activates TrkB, TrkC, AKT and ERK in C57BL/6J mice. LM22B-10 (50 mg/kg, i, p,) shows increased phosphorylation at TrkBY817 and TrkCY820. LM22B-10 activates synaptic TrkB and TrkC and increases pre-and post-synaptic proteins and spine density in aged mice.
• In Vitro:
  LM22B-10 exhibits maximum neurotrophic survival activity levels that are higher than those maximally achieved with BDNF (53 ± 7.2% above BDNF at 0.7 nM) and NT-3 (91 ± 8.6% above NT-3 at 0.7 nM) with an EC50 value of 200-300 nM. LM22B-10 (1000 nM) induces neurites of significantly larger average lengths, up to -40 μM. LM22B-10 (250-2000 nM) binds to TrkB-Fc and TrkC-Fc in a dose-dependent manner. LM22B-10 inhibits binding of BDNF to TrkB-expressing cells and NT-3 to TrkC-expressing cells. LM22B-10 promotes cell survival and functions preferentially through TrkB and TrkC. LM22B-10, but not BDNF or NT-3, promotes neurite outgrowth in an inhibitory environment. LM22B-10 induces patterns of Trk and downstream signaling activation that are distinct from those of BDNF and NT-3. LM22B-10 also induces TrkB, TrkC, AKT and ERK activation in hippocampal neurons in culture.
