Selective M3 muscarinic receptor antagonist (pKi values are 8.52, 7.93, 7.90 and 7.78 for M3, M2, M1 and M4 receptors respectively). Displays higher affinity at ileal M3 receptors (pKi = 9.3) compared to oesophageal and tracheal M3 receptors (pKi values are 8.8 and 8.2 respectively). Inhibits gastrointestinal motility in vivo in the absence of cardiovascular effects.

Literature in this Area
Alzheimer's disease (AD) is a degenerative brain disease and the most common cause of dementia, affecting approximately 47 million people worldwide. Updated in 2015, this poster summarizes the structural and functional changes observed in the progression of this neurodegenerative disease, as well as classic AD drug targets.
Learning & Memory Poster
Recognition memory enables us to make judgements about whether or not we have encountered a particular stimulus before. This poster outlines the cellular mechanisms underlying recognition memory and its links to long-term depression, as well as the use of pharmacological intervention to assess the role of neurotransmitters in recognition memory.
Schizophrenia is a debilitating psychiatric disorder that affects 1% of the worldwide population. This poster describes the neurobiology of Schizophrenia, as well as highlighting the genetic and environmental factors that play a fundamental role in the etiology of the disease. The current and emerging drug targets are also discussed.
