class, effects, and the receptor fingerprint, side by side; add up to four, then source the whole stack
Popular head-to-heads →5-HT4 receptorHigh-affinity partial agonist; Gs-coupled stimulation of adenylyl cyclase and cyclic AMP
Hippocampal and cortical acetylcholine releaseFacilitates evoked acetylcholine output
Amyloid precursor protein processing (alpha-secretase)Promotes non-amyloidogenic cleavage and sAPPalpha release
Neuroinflammation (astrogliosis and microgliosis)Reduces glial reactivity after chronic dosing
5-HT4 receptorSelective, brain-penetrant partial agonist; Gs-coupled cyclic AMP signalling
Hippocampus (memory encoding)Increases activation to novel versus familiar stimuli in patients
Medial and inferior frontal cortexAugments activation during emotional face processing
Emotional processing (depression)Reduces self-reported depression, anxiety, and negative affect early
checking RS-67333 and PF-04995274: no hard conflicts (1 to watch), but the amber pairs carry interactions to be careful with.
both are strongly serotonergic; combining them raises total serotonin load and the risk of serotonin syndrome, so this needs real care.
