Chemical Structure
ANA-12
- CAS No.: 219766-25-3
- Formula:C22H21N3O3S
- Molecular Weight:407.49
IUPAC Name: N-(2-((2-oxoazepan-3-yl)carbamoyl)phenyl)benzo[b]thiophene-2-carboxamide
InChIKey: TUSCYCAIGRVBMD-UHFFFAOYSA-N
SMILES: O=C(C1=CC2=CC=CC=C2S1)NC3=CC=CC=C3C(NC4C(NCCCC4)=O)=O
Biological Activity: ANA-12 is a brain-penetrant, selective TrkB antagonist with IC50 values of 45.6 nM and 41.1 μM, and Kd values of 10 nM and 12 μM, for high- and low-affinity sites, respectively. ANA-12 specifically inhibits BDNF-induced TrkB receptor activation and its downstream signaling cascades by directly and non-competitively binding to the TrkB receptor, without affecting the functions of TrkA and TrkC. ANA-12 is used in research concerning neuropsychiatric disorders (such as depression and anxiety), acute and chronic pain, neuroimmune inflammation, and the mechanisms of learning and memory[1][2][3][4][5][6][7].
