Daeatal (Dynorphin A ethylamide (1-9)) is an ethylamine-modified dynorphin fragment that can be used in the study of analgesia, addiction, depression, etc. Dynorphin A is an endogenous opioid peptide involved in inhibitory neurotransmission in the central nervous system (CNS). Dynorphin A is a highy potent kappa opioid receptor (KOR) agonist, and is also an agonist for other opioid receptors, such as mu (MOR) and delta (DOR). Dynorphin A can induce neuronal death, and can be used in the research of neurological disease .

Sialorphin	ERK Androgen Receptor Opioid Receptor Enteropeptidase mTOR Aminopeptidase	Neurological Disease Inflammation/Immunology Cancer
Sialorphin is a neutral endopeptidase (NEP) and aminopeptidase N (APN) inhibitor that responds to androgen signals. Sialorphin blocks the degradation of endogenous opioid peptides and interacts with μ-, δ-, κ-opioid *receptors. Sialorphin regulates the ERK/mTOR* signaling pathway by inducing cell cycle arrest, enhancing ERK1/2 activity, and reducing the phosphorylation levels of mTOR, 4E-BP1, p70S6K; accordingly, Sialorphin exhibits antiproliferative activity against colorectal cancer, glioma and prostate cancer cells without cytotoxicity. In addition, Sialorphin also produces antinociceptive responses, regulates sexual behavior, relaxes corpus cavernosum smooth muscle, and alleviates experimental colitis. Sialorphin is also a copper (II) ion-binding ligand. Sialorphin has been used in mechanistic studies related to cancer, pain management and inflammatory bowel disease .

HY-B0188S

Mianserin-d3

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 .

HY-17609S1

Difelikefalin-d5 hydrochloride
Difelikefalin-d₅ (CR-845-d₅) hydrochloride is the deuterium labeled Difelikefalin (HY-17609). Difelikefalin (CR-845) is a peripherally restricted and selective agonist of kappa opioid receptor (KOR). Difelikefalin produces anti-inflammatory effects and has the potential in modulating pruritus in conditions such as chronic kidney disease .

Samidorphan-d5

Samidorphan-d5 (ALKS-33-d5) is is a deuterated compound of Samidorphan. Samidorphan is an orally active opioid system modulator that binds with high affinity to μ-opioid, κ-opioid, and δ-opioid receptors. Samidorphan is a μ-opioid receptor antagonist and a partial agonist at k-opioid and δ-opioid receptors. Samidorphan acts primarily as an opioid receptor antagonist in vivo .

HY-17609S

Difelikefalin-d5
Difelikefalin-d₅ (CR-845-d₅) is deuterium labeled Difelikefalin. Difelikefalin (CR-845; FE-202845) is a peripherally restricted and selective agonist of kappa opioid receptor (KOR). Difelikefalin produces anti-inflammatory effects and has the potential in modulating pruritus in conditions such as chronic kidney disease .

HY-W654256

Matrine-d3

Matrine-d₃ (Matridin-d₃) is a deuterium labeled Matrine (HY-N0164). Matrine (Matridin-15-one) is an alkaloid found in plants from the Sophora genus that can act as a kappa opioid receptor and u-receptor agonist. Matrine has a variety of pharmacological effects, including anti-cancer, anti-oxidative stress, anti-inflammation and anti-apoptosis effects. Matrine is potential in the research of disease like human non-small cell lung cancer, hepatoma, papillary thyroid cancer and acute kidney injury (AKI) .

HY-123689S

Samidorphan-d4

Samidorphan-d4 is the deuterium labeled Samidorphan(HY-123689).Samidorphan (ALKS-33) is an orally active opioid system modulator that has a high affinity for binding with μ‐opioid, κ‐opioid, and δ‐opioid receptors. Samidorphan acts as an antagonist at μ‐opioid receptors and acts as a partial agonist at k-opioid and δ‐opioid receptors. Samidorphan primarily acts as an opioid receptor antagonist in vivo .

HY-106605S

Flumezapine-d8 hydrochloride

Flumezapine-d₈ (LY 120363-d₈) hydrochloride is deuterated labeled Flumezapine hydrochloride. Flumezapine hydrochloride is a potent and balanced antagonist of the dopamine D2 receptor and the 5-hydroxytryptamine receptor (5-HT receptor). Flumezapine hydrochloride does not alter the increase in serum cortisol caused by κ-opioid receptor agonists. Flumezapine hydrochloride inhibits the conditioned avoidance response in rats and has a low risk of extrapyramidal side effects. Flumezapine hydrochloride can be used in antipsychotic research.
