nTRD22
Based on 1 Customer Validation
nTRD22 is an RNA-binding allosteric modulator targeting TDP-43. nTRD22 binds to the N-terminal domain of TDP-43, thereby allosterically regulating the RNA-binding domain of TDP-43 and reducing its RNA-binding ability. nTRD22 decreases the TDP-43 protein level in primary motor neurons. nTRD22 alleviates motor dysfunction in amyotrophic lateral sclerosis models. nTRD22 is applicable to related research on amyotrophic lateral sclerosis.

Biological Activity
nTRD22 (0.03 μM-1 mM) binds to full-length TDP-431-260 with an apparent Kd of 145 ± 3 μM and to the isolated N-terminal domain TDP-431-102 with an apparent Kd of 96 ± 36 μM[1].
nTRD22 inhibits TDP-431-260 binding to UG6 RNA with an IC50 of ~100 μM in an alpha assay[1].
nTRD22 (0.1-500 μM) inhibits TDP-431-260 binding to (UG)6 RNA with an IC50 of ~145 μM and achieves ~30% inhibition of the interaction in an SPR assay[1].
