|Description||SUN11602 is a small synthetic compound that mimics the neuroprotective activities of bFGF and activates key molecules in the FGF receptor-1-mitogen-activated protein kinase/extracellular signal-regulated kinase-1/2 kinase (FGFR-1-MEK/ERK) signaling pathway.|
Physiological actions of SUN11602 mimic several phenomena of the neuroprotection that is induced by bFGF. SUN11602 plays a pivotal role in allowing primary cultured neurons to survive in adverse environments of glutamate toxicity and activating intracellular key molecules that are involved in the neuroprotective mechanisms. These actions are quite similar to those of bFGF. Such neuroprotective mechanisms are specific and distinctive to SUN11602 and bFGF and differs clearly from those of the other growth factors that are investigated. But unlike bFGF, SUN11602 can either directly or indirectly trigger the phosphorylation of the cytosolic domain of the FGFR without binding to the extracellular domain of the FGFR-1. SUN11602 demonstrates no cell proliferative activity of somatic cells, unlike bFGF. SUN11602 significantly affects neuronal survival in adverse conditions through a FGFR1-mitogen-activated protein kinase/extracellular signal-regulated kinase-1/2 kinase (FGFR-1–MEK/ERK) signaling pathway.
|In vivo||In WT mice, SUN11602 and bFGF increase the levels of newly synthesized Calb in cerebrocortical neurons and suppress the glutamate-induced rise in intracellular Ca2+. This Ca2+-capturing ability of Calb allows the neurons to survive severe toxic conditions of glutamate. In contrast, Calb levels remain unchanged in Calb-/- mice after exposure to SUN11602 or bFGF, and due to a loss of function of the gene, these neurons are no longer resistant to toxic conditions of glutamate. Neuroprotective activities of SUN11602 and FGF-2 are due to exogenously induced hyperexpression of CalB in hippocampal neurons. The pharmacokinetic properties of SUN11602 appear to hold promise in terms of bioavailability (>65%) after oral administration in rodents (rats and mice) and dogs (beagles).|

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
