[CAS NO. 704869-38-5]  SUN11602

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.
