(R)-(+)-Citronellal alleviates the bitterness of caffeine by antagonizing the bitter taste receptors Tas2r43 (IC₅₀ = 84 μM) and Tas2R46. (R)-(+)-Citronellal generates analgesic activity by activating the opioid receptor (broad-spectrum opioid receptor) pathway, and its effect is particularly significant for inflammatory pain.

Sinomenine (Standard) is the analytical standard of Sinomenine. This product is intended for research and analytical applications. Sinomenine, an alkaloid extracted from?Sinomenium acutum, is a blocker of the NF-κB activation. Sinomenine also is an activator of μ-opioid receptor.

N-Desmethyl-loperamide is a major metabolite of loperamide, a drug that selectively activates peripheral μopioid receptors with a K_i value of 0.16 nM. N-Desmethyl-loperamide is a substrate of the ATP-dependent efflux transporter P-glycoprotein.

Hemorphin-7 is a hemorphin peptide, an endogenous opioid peptide derived from the β-chain of hemoglobin. Hemorphin peptides exhibits antinociceptive and antihypertensive activities, activating opioid receptors and inhibiting angiotensin-converting enzyme (ACE).

RB 101 is a blood-brain barrier-crossing prodrug as well as aminopeptidase N and neutral endopeptidase-24.11 inhibitor. RB 101 blocks enkephalin breakdown, elevates extracellular enkephalin levels and activate δ-opioid receptor and dopamine D1 receptor. RB 101 can be used for the research of pain, depressive syndromes, and diabetic neuropathy.

Axomadol (EN3324) is a centrally active analgesic agent with opioid agonistic properties and inhibitory effects on the reuptake of monoamines.

Mianserin-d3 is the deuterium labeled Mianserin (HY-B0188). Mianserin (Mianserine) is an orally active H1 receptor antagonist. Mianserin can activate κ-opioid receptor and octopamine receptor. Mianserin increases ERK1/2 and CREB phosphorylation, and antagonizes full κ-opioid agonist and Dynorphin A (HY-P1333)-induced MAPK phosphorylation. Mianserin modulates social and exploratory behaviour, raises electroconvulsive thresholds. Mianserin can be used for the research of neurological disease, such as depression and epilepsy.

PL265 is an orally active dual enkephalinase inhibitor. PL265 is a prodrug of PL254, which can simultaneously and efficiently inhibit neutral endopeptidase (Neprilysin) and Aminopeptidase N. PL265 can effectively protect and significantly increase the local concentration of enkephalins (such as Met-Enkephalin and Leu-Enkephalin) released by cells at the pain or inflammation sites, thereby activating μ and δ opioid receptors to produce a potent analgesic effect. PL254 can also inhibit leukotriene A4 hydrolase (LTA4H), which may contribute to its additional anti-inflammatory effect by reducing the production of pro-inflammatory mediator leukotriene B4 (LTB4). PL265 can be used in non-addictive chronic pain research.
