Tideglusib (NP-12, NP031112) is a potent and irreversible ^[1] small molecule glycogen synthase kinase 3 (GSK-3) inhibitor. ^[2]

Clinical trials

Tideglusib has been evaluated in clinical trials for:

• Alzheimer's disease and progressive supranuclear palsy. Both clinical trials were discontinued in 2011 (PSP) and 2012 (Alzheimer's disease) due to lack of efficacy ^{[3] [4] [5] [6] [1]}
• Congenital/juvenile-onset myotonic muscular dystrophy type I. ^[7]

Research

Tideglusib is or has been under investigation for multiple applications:

• Tooth repair mechanisms that promotes dentine reinforcement of a sponge structure until the sponge biodegrades, leaving a solid dentine structure. In 2016, the results of animal studies were reported in which 0.14 mm holes in mouse teeth were permanently filled. ^{[8] [9]}
• Preclinical in vitro studies were carried out for neuroblastoma and ovarian cancer with significant ROS-induced apoptosis. ^{[10] [11]}
• Arrhythmogenic Right Ventricular Cardiomyopathy as of 2025. ^[12]
