PR-619 is a Broad-Range DUB Inhibitor

Ubiquitination is a post-translational modification where the polypeptide ubiquitin is attached to lysine residues of substrate proteins. This process is reversible, and ubiquitin removal is orchestrated by a large family of deubiquitinating enzymes (DUBs). DUBs fall into six subfamilies based on sequence and domain similarity. Ubiquitination and deubiquitination together...

NSC 33994 is a Selective JAK2 Inhibitor

Janus kinases (JAK) play a crucial role in cytokine-mediated signal transduction. Activated JAKs tyrosine autophosphorylate and phosphorylate specific tyrosine residues on the C-terminal end. This results in the recruitment and activation of the STAT proteins. Activated STATs subsequently translocate into the nucleus where they alter specific gene transcription patterns....

PQR530 is an Orally Active and Brain-Penetrant Dual PI3K, mTORC1/2 Inhibitor

Several brain disorders, such as epilepsy, found dysregulation of the PI3K/Akt/mTOR pathway. The PI3K-AKT/mTOR pathway is a central player of intracellular signaling, regulating neuronal survival, growth, and plasticity. Aberrant activation of this signaling pathway drives the progression of malignant tumors. The mutation of growth factor receptors, PI3K, loss of...

GSK621 is a Specific AMPK Activator, Inducing Autophagy and Apoptosis

AMPK is an enzyme, which plays a role in cell energy homeostasis. It mainly activates glucose and fatty acid uptake and oxidation when the cell energy is low. Specifically, AMPK is a major regulator of cell metabolism, which can exert its carcinogenic or antitumor activities. Besides, the activation of...

THZ-P1-2 is a Selective PI5P4K Inhibitor

Phosphatidylinositol 5-phosphate (PI-5-P) is one of the seven phosphoinositides. They regulate a wide range of cellular functions. They localize in the nucleus, Golgi, endoplasmic reticulum, and at the plasma membrane. PI-5-P is an oxidative stress-induced regulator of AKT activation. The phosphorylation of the low abundance phosphoinositide PI-5-P at the...

MK-2206 is an Orally Active and Selective Allosteric Akt Inhibitor

Nasopharyngeal carcinoma (NPC) is a squamous cell carcinoma arising from the epithelium lining of the posterior nasopharynx. In a word, NPC causes very serious health problems in these areas. NPC is highly sensitive to radiation and chemotherapy. However, even with combined radiation and chemotherapy treatment, the prognosis for the...
