Puberulin
Puberulin is a coumarin compound and an orally effective analgesic. Puberulin is present in Choisya ternata var. Sundance. Puberulin exerts analgesic activity against chemical and heat-induced pain agents in mouse models, and this activity does not involve opioid receptors or muscarinic receptors. Puberulin can be used in the research of neuropathic pain.

Biological Activity
Puberulin (25-300 μg/mL) exhibits good linearity in HPLC quantification, as demonstrated by a regression coefficient greater than 0.99[1].
Puberulin is successfully isolated as a colourless crystalline solid from Choisya ternata var. Sundance ethanol extract using countercurrent chromatography, with purity confirmed by HPLC[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Puberulin (0.3-10 mg/kg; p.o.; single dose) exerts antinociceptive activity against Glutamate (HY-14608)-induced pain in male Swiss Webster mice at oral doses of 0.3 mg/kg and 1 mg/kg, but not at 10 mg/kg[1].
Puberulin (10 mg/kg; p.o.; single dose) does not exhibit antinociceptive activity against Capsaicin (HY-10448)-induced pain in male Swiss Webster mice at the 10 mg/kg oral dose[1].
Puberulin (0.3-10 mg/kg; p.o.; single dose) exhibits central antinociceptive activity in male Swiss Webster mice across oral doses of 0.3 mg/kg, 1 mg/kg, and 10 mg/kg, significantly increasing hot plate nociception thresholds[1].
Puberulin (1 mg/kg; p.o.; single dose) exhibits central antinociceptive activity in male Swiss Webster mice at the 1 mg/kg oral dose that is not mediated by opioid receptors, as Naloxone (HY-17417A) does not inhibit its effect[1].
Puberulin (1 mg/kg; p.o.; single dose) exhibits central antinociceptive activity in male Swiss Webster mice at the 1 mg/kg oral dose that is not mediated by muscarinic receptors, as Atropine (HY-B1205) does not inhibit its effect[1].
