pheochromocytoma

Crocin (Gardenia Yellow) is a water-soluble carotenoid pigment of saffron (Crocus sativus L. ) that has been used as a spice for flavoring and coloring food preparations, and in Chinese traditional medicine as an anodyne or tranquilizer. Crocin suppresses tumor necrosis factor (TNF)alpha-induced apoptosis of pheochromocytoma (PC12) cells by modulating mRNA expressions of Bcl-2 family proteins, which trigger downstream signals culminating in caspase-3 activation followed by cell death. Crocin prevented the activation of nSMase by enhancing the transcription of gamma-glutamylcysteinyl synthase, which contributes to a stable glutathione supply that blocks the activity of nSMase.

NG-012, a nerve growth factor (NGF) potentiator, was isolated from the culture broth of Penicillium verruculosum F-4542. It enhances neurite outgrowth as induced by NGF in the rat pheochromocytoma cell line (PC12) [1].

Homovanillic acid sulfate is used as a reagent to detect oxidative enzymes, and is associated with dopamine levels in the brain.In psychiatry and neuroscience, brain and cerebrospinal fluid levels of homovanillic acid are measured as a marker of metabolic

Gynosaponin TN-2, demonstrating anti-Parkinsonian activity, mitigates L-DOPA (100 and 200 μM)-induced apoptotic cell death in pheochromocytoma 12 cells through the modulation of extracellular signal-regulated protein kinases 1 and 2 activation.

14-Norpseurotin A shows good antileishmanial and moderate anticancer activities. It also displays significant antimicrobial activities against Escherichia coli, Bacillus subtilis, and Micrococcus lysoleikticus with MICs of 3.74, 14.97, and 7.49 microM , r

Vanillylmandelic acid, the end product of the metabolism of catecholamines, epinephrine, and norepinephrine, has antioxidant activity and is commonly used to help diagnose pheochromocytoma, as well as its elevation in association with depressive symptoms.
