Paynantheine is an alkaloid with antinociceptive properties, found in Mitragyna speciosa. It also acts as an agonist at 5-HT1AR and 5-HT2BR receptors, inducing lower lip contraction and providing antinociception in rats.

KOR agonist 5 (Compound 10a) is both a KOR/MOR modulator, exhibiting agonistic effects on KOR and antagonistic effects on MOR. It effectively blocks morphine-induced antinociception and gastrointestinal motility inhibition. KOR agonist 5 is applicable in research related to substance use disorder (SUD).

Tingenone is a pentacyclic triterpene. It induces peripheral antinociception due to opioidergic activation.

Leucylarginine hinders antinociception induced by L-arginine.

ONO-1714 is a inducible nitric oxide synthase (NOS-2) inhibitor. ONO-1714 reduces hyperoxic lung injury in mice. ONO-1714 attenuates inflammation-related large bowel carcinogenesis in male Apc(Min/+) mice. ONO-1714 also inhibits neuronal NOS and exerts an

ZCZ011 is a positive allosteric modulator of the cannabinoid CB1 receptor. ZCZ011 is brain penetrant, increased the potency of orthosteric agonists in mouse behavioral assays indicative of cannabimimetic activity, including antinociception, hypothermia, c

MS 15203 is a selective GPR171 agonist that increases morphine antinociception and is effective in reducing chronic pain. It can reduce chronic neuropathic and inflammatory pain in male mice.

(S)-AM1241 binds to cannabinoid (CB) receptors and is selective for the CB2 over the CB1 receptor (Kis = 658 and >10,000 nM, respectively, in a membrane assay using human receptors). (S)-1241 acts as an agonist at human, rat, and mouse CB2 receptors but shows greater activity at human CB2 (EC50 = 131 nM) than at rat and mouse CB2 receptors (EC50 = 785 and 2,000 nM, respectively). Similar to the racemate AM1241 , (S)-AM1241 produces antinociception to thermal, but not mechanical, pain in rats. The pain-reducing effect of (S)-AM1241 is blocked by the CB2-specific inhibitor SR 144528 but not by either the CB1-selective inhibitor rimonabant or the opioid receptor blocker naloxone .

β-Endorphin (1-27) is an endogenous peptide that binds to μ-, δ-, and κ-opioid receptors (Kis = 5.31, 6.17, and 39.82 nM, respectively, in COS-1 cells expressing rat receptors). It binds to rat and mouse brain membrane preparations (IC50s = 1.1 and 5.7 nM, respectively) and induces chemotaxis of human monocytes in vitro when used at a concentration of 1 nM. Intracerebroventricular administration of β-endorphin (1-27) increases the latency to tail withdrawal in response to thermal stimulation in mice with a median antinociceptive dose (AD50) of 1,500 pmol per animal. It inhibits antinociception induced by β-endorphin in mice in response to thermal stimuli when administered at a dose of 65 pmol per animal. In rats, β-endorphin (1-27) does not affect drug-associated place preference when administered at doses up to 20 μg, i.c.v., but inhibits β-endorphin-induced place preference when administered at a dose of 10 μg per animal.
