DIPQUO is an activator of bone marker alkaline phosphatase (ALP). DIPQUO promotes the differentiation of mouse and human osteoblasts by activating p38MAPK-β. The EC50 in C2C12 cells was 6.27 μM.
myomiR-IN-1 is a myomiRs inhibitor that acts by inhibiting the translation of myoD in C2C12 cells without changing the expression level of myoD mRNA and downregulating the expression of differentiation markers.
CC260 is a selective PI5P4Kα and PI5P4Kβ inhibitor with Kis of 40 nM and 30 nM, respectively. CC260 does not inhibit or weakly inhibits other protein kinases, such as Plk1 and RSK2. CC260 can be used for cell energy metabolism, diabetes and cancer research[1]. In cultured C2C12 myotubes, CC260 (20 μM) enhances Insulin-induced Akt phosphorylation at both Thr-308 and Ser-473 but suppresses S6K phosphorylation (Thr-389) by mTORC1[1]. CC260 (2.5 μM, 5 μM, 10 μM, 20 μM) significantly increases phosphorylation of acetyl-CoA carboxylase (ACC) in a dose-dependent manner[1]. CC260 treatment reduces the ability of BT474 cells to survive serum starvation, which could be rescued by expressing the PI5P4Kβ refractory mutant[1]. In BT474 cells, CC260 treatment causes an increase in glycolytic ATP production[1]. [1]. Song Chen, et al. Pharmacological inhibition of PI5P4Kα β disrupts cell energy metabolism and selectively kills p53- tumor cells. Proc Natl Acad Sci U S A. 2021 May 25;118(21):e2002486118.
IBS008738, a potent TAZ activator, stabilizes TAZ, elevates the unphosphorylated TAZ level, enhances the interaction of MyoD with the myogenin promoter, upregulates gene transcription regulated by MyoD, and competes with myostatin in C2C12 cells. Additionally, IBS008738 promotes myogenesis in C2C12 cells and facilitates muscle repair in a model of muscle injury.
KYL peptide is an EphA4 receptor tyrosine kinase inhibitor (Kd = 0.8 μM); inhibits EphA4-EphrinA5 interactions (IC50 = 6.34 μM). Prevents AβO induced synaptic damage, dendritic spine loss and prevents the blocking of LTP in hippocampal CA3-CA1 transmissions. Exhibits a long half life in cell culture media (8 and 12 hours in PC3 and C2C12 media respectively). Neuroprotective.
