bay-k-8644 and Pituitary Neoplasms

bay-k-8644 has been researched along with Pituitary Neoplasms in 33 studies

3-Pyridinecarboxylic acid, 1,4-dihydro-2,6-dimethyl-5-nitro-4-(2-(trifluoromethyl)phenyl)-, Methyl ester: A dihydropyridine derivative, which, in contrast to NIFEDIPINE, functions as a calcium channel agonist. The compound facilitates Ca2+ influx through partially activated voltage-dependent Ca2+ channels, thereby causing vasoconstrictor and positive inotropic effects. It is used primarily as a research tool.
Bay-K-8644 : A racemate comprising equimolar amounts of (R)- and (S)-Bay-K-8644
methyl 2,6-dimethyl-5-nitro-4-[2-(trifluoromethyl)phenyl]-1,4-dihydropyridine-3-carboxylate : A pentasubstituted dihydropyridine carrying methoxycarbonyl, 2-(trifluoromethyl)phenyl and nitro substituents at positions 3, 4 and 5 respectively as well as two methyl substituents at positions 2 and 6.

Pituitary Neoplasms: Neoplasms which arise from or metastasize to the PITUITARY GLAND. The majority of pituitary neoplasms are adenomas, which are divided into non-secreting and secreting forms. Hormone producing forms are further classified by the type of hormone they secrete. Pituitary adenomas may also be characterized by their staining properties (see ADENOMA, BASOPHIL; ADENOMA, ACIDOPHIL; and ADENOMA, CHROMOPHOBE). Pituitary tumors may compress adjacent structures, including the HYPOTHALAMUS, several CRANIAL NERVES, and the OPTIC CHIASM. Chiasmal compression may result in bitemporal HEMIANOPSIA.

ExcerptRelevanceReference
"Serum from patients with IDDM increased L-type calcium channel activity of insulin-producing cells and of GH3 cells derived from a pituitary tumor."1.29Increased activity of L-type Ca2+ channels exposed to serum from patients with type I diabetes.

"Lidocaine was much less effective in inhibiting secretion induced by 1 microM phorbol 12-myristate 13-acetate (TPA) or 5 microM forskolin."1.28Lidocaine inhibits prolactin secretion in GH4C1 cells by blocking calcium influx. ( Greer, MA; Sato, N; Wang, X, 1992)
"Pretreatment with thapsigargin blocked the ability of TRH to cause a transient increase in both [Ca2+]c and 45Ca2+ efflux."1.28Thapsigargin, but not caffeine, blocks the ability of thyrotropin-releasing hormone to release Ca2+ from an intracellular store in GH4C1 pituitary cells.
