Indirubin-3′-oxime (IDR3O), a synthetic derivative of indirubin, is a potent inhibitor of cyclin-dependent kinases (CDKs) and glycogen synthase kinase 3β (GSK3β). Indirubin-3′-oxime directly inhibits the activity of all three isoforms of JNK (JNK1, JNK2, and JNK3), with IC₅₀s of 0.8 μM, 1.4 μM, and 1.0 μM, respectively. Indirubin-3′-oxime can enhance height growth via activation of Wnt/β-catenin signaling in chondrocytes.

PT109 is an orally active, blood-brain barrier permeable multi-kinase inhibitor. By inhibiting PTBP1, PT109 promotes the switch of pyruvate kinase isoform from PKM2 to PKM1, thereby effectively inhibiting the proliferation and migration of glioblastoma multiforme and inducing its reprogramming into oligodendrocytes. PT109 also targets and regulates key signaling molecules such as JNK, SGK1, GSK3β to exert neuroprotective effects including promoting neurogenesis, inducing synapse formation and alleviating neuroinflammation. In Alzheimer's disease models, PT109 exhibits significant efficacy in improving spatial learning ability, along with excellent in vivo pharmacokinetic properties. PT109 can be used to investigate metabolic reprogramming of glioblastoma multiforme and neuroprotective mechanisms of Alzheimer's disease.
