Dolastatin 15, a depsipeptide derived from Dolabella auricularia, is a potent antimitotic agent structurally related to the anti-tubulin agent Dolastatin 10. Dolastatin 15 can be used as an ADC cytotoxin and it induces cell cycle arrest and apoptosis in m
NSC745885 is an effective down-regulator of EZH2 via proteasome-mediated degradation. NSC745885 is also an effective anti-tumor agent that displays selective toxicity against multiple cancer cell lines but not normal cells. NSC745885 offers possibilities
Quinacrine is a compound with multiple actions that is commonly used as an anti-protozoal agent. It has also been shown to be a highly potent autophagy inhibitor, although the dose required to achieve this effect is considerably cytotoxic (LD50 = 2.5 μM). Quinacrine analog 34 is a derivative of quinacrine that was designed with an improved cell viability profile (LD50 = 27 μM) to inhibit autophagy. At a minimum concentration of 0.5 μM, this compound has been shown to increase the protein levels of the autophagy biomarker LC3-II and to induce lysosome deacidification.
Insulin-degrading enzyme (IDE) is a thiol-sensitive zinc-metallopeptidase that acts as the major insulin-degrading protease in vivo, mediating the termination of insulin signaling. [1] In addition to regulating insulin action in diabetes pathogenesis, IDE plays a role in Varicella-Zoster virus infection and degradation of amyloid-β, a peptide implicated in Alzheimer's disease. ML-345 is a small molecule inhibitor that selectively targets cysteine819 in IDE with an EC50 value of 188 nM. [2] It demonstrates 10-fold selectivity for IDE over a panel of enzymes with reactive cysteine residues.[2] Reference:[1]. Maianti, J.P., McFedries, A., Foda, Z.H., et al.
