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.

| Biological target: | LM22B-10 is an activator of TrkB/TrkC neurotrophin receptor, and can induce TrkB, TrkC, AKT and ERK activation in vitro and in vivo. |
| In vitro activity: | The cells were treated with LM22B-10 (an ERK activator) or transfected with the constitutive activation of the mitogen-activated protein kinase 1 (CaMEK) gene. Administering LM22B-10 or transfecting the CaMEK gene significantly activated the phosphorylation levels of ERK1/2 protein and reduced the proportion of cardiomyocyte apoptosis (P<0.05). Reference: Ann Transl Med. 2022 Nov;10(22):1238. https://pubmed.ncbi.nlm.nih.gov/36544682/ |
| In vivo activity: | In vivo model of PNI (perineural invasion) was established via inoculating PANC-1 cells into mice. PANC-1 cells and mice were also treated with LM22B-10 (an activator of TrkC) to confirm the mechanisms involving NT-3/TrkC in PNI of PC both in vivo and in vitro. LM22B-10 partially abolished the effects of MMP1 knockdown both in vivo and in vitro. Reference: J Clin Lab Anal. 2022 Nov;36(11):e24719. https://pubmed.ncbi.nlm.nih.gov/36181286/ |
