The ubiquitin C-terminal hydrolase L1 (UCH-L1) is a member of a family of de-ubiquitinating enzymes that can generate free ubiquitin from ubiquitin precursors via its ubiquitin ligase activity. By associating with free ubiquitin, it also prevents its degradation. Neuronal UCH-L1 has been linked to Parkinson's...

A series of 2,5-dimethoxyphenethylamines, substituted at the four position of the aromatic ring, have psychoactive effects. 2C-B (hydrochloride) (Cay-11734) is a hallucinogenic designer drug that has emerged as a drug of abuse. 2C-B-BZP is a benzylpiperazine analog of 2C-B. This product is intended for forensic and...

SU 9516 is a 3-substituted indolinone that has anti-proliferative and pro-apoptotic activity in tumor cells. It is a potent inhibitor of several cyclin-dependent kinases (CDKs) with selectivity for Cdk2 (IC50s = 22, 40, and 200 nM for Cdk2/cyclin A, Cdk1/cyclin B, and Cdk4/cyclin D1). It does not inhibit PKC, p38,...

NSC 697923 is a selective inhibitor of the E2 ubiquitin-conjugating enzyme Ubc13 when heterodimerized with Uev1A, blocking polyubiquitin chain formation at concentrations of 0.5 to 2 µM in vitro. It also inhibits NF-kappaB activation by PMA and other agonists, presumably through its effects on Ubc13. NSC 697923...
