VU0183254 is an insect olfactory receptors (ORs) agonist acting at a binding site on the Orco subunit, capable of broadly inhibiting odor-mediated OR complex activation.
Satratoxin G is a trichothecene mycotoxin of Stachybotrys chartarum and has been shown to selectively induces apoptosis in olfactory sensory neurons (OSNs) of the nose and brain.
Petromyzonol is a tetrahydroxy stearol which serves as the primary spawning pheromone in adult sea lamprey. It is produced in the bile of sea lamprey larvae from the bile acid precursor allocholic acid. While the adult sea lamprey is relatively insensitive to petromyzonol itself, the C-24 sulfate ester (petromyzonol sulfate) is a pheromone and a spawning chemoattractant which can be detected at very low concentrations by lamprey olfactory chemoreceptors. Petromyzonol, petromyzonol sulfate, and allocholic acid are all found in water samples from fresh water streams bearing larval lamprey populations.[1]
Bourgeonal is an agonist of human testicular olfactory receptor hOR17-4. It increases cytosolic calcium levels in human spermatozoa, acts as a chemoattractant, and increases swimming speed in sperm chemotaxis assays in a concentration-dependent manner.
