Brimonidine-d4 is intended for use as an internal standard for the quantification of brimonidine (Item No. 15426) by GC- or LC-MS. Brimonidine is an agonist of α2-adrenergic receptors (α2-ARs; Kis = 2.7, 52, and 44 nM for α2A, α2B, and α2C-ARs, respectively, in CHO cells).{42418} It is selective for α2-ARs over α1-ARs (Ki = 1,800 nM in human brain). Brimonidine lowers intraocular pressure in DBA/2J mice, a model of glaucoma, to control levels when applied topically to the eye as a 0.1% solution.{42419} It also inhibits glutamate release, prevents upregulation of NMDA receptors containing NR1 and NR2A subunits, and protects rat retinal ganglion cells against glutamate excitotoxicity in a rat model of retinal ischemia when administered at a dose of 1 mg/kg per day.{25329} Formulations containing brimonidine have been used in the treatment of open-angle glaucoma and ocular hypertension.

  • PtdIns-(3

    PtdIns-(3,4,5)-P3-biotin (sodium salt) – 25 µg

    The PtdIn phosphates play an important role in the generation and transduction of intracellular signals.{8344,4096,14518} PtdIns-(3,4,5)-P3-biotin is an affinity probe which allows the PIP3 to be detected through an interaction with the biotin ligand. This design allows PtdIns-(3,4,5)-P3-biotin to serve as a general probe for any protein with a high affinity binding interaction with inositol-(3,4,5)-triphosphate phospholipids, such as phosphatidylinositol 3-kinase, PTEN, or PH-domain-containing proteins.
