MPM-1, an Anticancer agent, is a Marine Eusynstyelamides Mimic

Autophagy  is the natural and conservative degradation of cells. Specifically, it can remove unnecessary or dysfunctional components through lysosomal-dependent regulation mechanisms. Besides, it allows the orderly degradation and recycling of cellular components. It eliminates molecular and subcellular elements through lysosomal-mediated degradation. This includes nucleic acids, proteins, lipids, and organelles...

Panobinostat is a Potent and Orally Active Non-selective HDAC Inhibitor

HDACs (Histone deacetylases) are a class of enzymes that remove acetyl groups from an ε-N-acetyl lysine amino acid on a histone, allowing the histones to wrap the DNA more tightly. This is important because acetylation and de-acetylation can regulate DNA expression. Acetylation is controlled by two antagonistic enzyme families:...

5-Azacytidine, a Nucleoside Analogue of Cytidine, Inhibits DNA Methylation

In the mammalian genome, DNA methylation is an epigenetic mechanism involving the transfer of a methyl group onto the C5 position of the cytosine to form 5-methylcytosine. DNA methylation regulates gene expression by recruiting proteins involved in gene repression or by inhibiting the binding of transcription factor(s) to DNA....

Chelerythrine is a Potent Protein kinase C Inhibitor

Chelerythrine is a natural benzo[c]phenanthridine alkaloid. It extracts from a number of plant species, such as Chelidonium majus, Macleaya cordata, Sanguinaria canadensis, etc. This compound exerts a wide spectrum of biological activities, including anti-cancer, anti-diabetes, anti-fungus, as well as a protective effect against the ethanol-induced gastric ulcer and the...

Deguelin, a Naturally Occurring Rotenoid, Acts as a Chemopreventive Agent

Head and neck squamous cell carcinoma (HNSCC) represents more than 5% of all cancers each year. In addition, breast cancer is a heterogeneous group of diseases. Approximately 60-70% of breast cancers express estrogen receptors (ER) and/or progesterone receptors (PR). About 20-30% of breast cancers have amplified levels of the...

ABT-737 is a Selective and BH3 Mimetic Bcl-2, Bcl-xL and Bcl-w Inhibitor

Bcl-2 protein family is a key regulator of apoptosis and a marker of B-cell lymphoma. Importantly, apoptosis is an important physiological process of selective cell clearance, involving a variety of biological events. Particularly, the Bcl-2 family is the most characteristic protein family involved in regulating apoptotic cell death. It...

Spautin-1 is a Specific and Potent Autophagy Inhibitor

Autophagy refers to the natural and conservative degradation of cells through lysosome dependent regulation mechanism. Specifically, it allows the orderly degradation and recovery of cellular components. At present, there are four forms of autophagy: macroautophagy, microautophagy, chaperone-mediated autophagy (CMA), and coprophagy. The catabolic process of macroautophagy is evolutionarily conserved...
