GtoPdb Ligand ID: 10429

Compound class: Synthetic organic
Comment: J30-8 is a selective JNK3 (a.k.a. mitogen-activated protein kinase 10; MAPK10) inhibitor. It is the most potent inhibitor from a series of compounds reported by Dou et al. (2019) that were identified using structure-based virtual, similarity and SAR screening stages [2]. JNK3 has been proposed as the primary kinase that is responsible for phosphorylating Aβ precursor protein (APP) at Thr668, which leads to accelerated Aβ formation and elevated plaque burden [1,3]. Pharmacological inhibition of JNK3 is therefore being explored as a novel modality for the treatment of Alzheimer's and other neurodegenerative diseases. J30-8 provides a suitable in vitro and in vivo tool to further study JNK3's role in these pathological conditions.

Bioactivity Comments
In APPswe/PS1dE9 Alzheimer model mice, J30-8 was found to inhibit phosphorylation of JNK, Aβ precursor and Tau proteins, to reduce plaque burden in the cortex and hippocampus, and to improve spatial learning impairment and memory deficit [2].
J30-8 exhibits excellent JNK3 isoform selectivity, and favourable kinome-wide selectivity.
