Application

p-Fluorohexahydro-sila-difenidol hydrochloride (pFHHSid) has been used:
  • as the M3/muscarinic acetylcholine receptor antagonist to study its involvement in carbachol induced Egr-1 biosynthesis using human neuroblastoma cells
  • as M3 receptor antagonist to test its involvement on N,N-diethyl-m-toluamide (DEET)-induced angiogenesis in human umbilical venous endothelial cells (HUVEC)
  • in a study to examine the role of aclidinium on human fibroblast to myofibroblast

Biochem/physiol Actions

The Fallopian tubes are sparsely innervated with cholinergic nerve fibers. Acetylcholine is released from these nerves and contracts the smooth muscles of the tubes. The aim of our study was to investigate the effect of acetylcholine on the isthmic segment

Carbachol-mediated activation of type M(3) muscarinic acetylcholine receptors induces the biosynthesis of the transcription factor Egr-1 in human SH-SY5Y neuroblastoma cells involving an activation of extracellular signal-regulated protein kinase. Carbachol triggered the phosphorylation of the ternary complex factor Elk-1, a
