Description:	AR-M 1000390 hydrochloride is an exceptionally selective, potent δ opioid receptor agonist with an EC50 of 7.2±0.9 nM for δ agonist potency.
In Vivo:	Rats are treated with 5, 100, and 600 μmol/kg of AR-M 1000390 (AR-M100390) for 3 and/or 7 days; another group of rats treated with 600 μmol/kg of compound are allowed to recover for 14 days. AR-M 1000390 (600 μmol/kg) causes vacuolation in the β-cell of the rat pancreas that is associated with depletion of insulin and hyperglycemia after 7 days of dosing. Treatment of rats with 600 μmol/kg of AR-M 1000390 results in vacuolation of the β-cell of the rat pancreas that is similar to that reported for cyclizine and cyproheptadine[2].
In Vitro:	AR-M 1000390 (Compound 6a) exhibits the binding affinities (IC50) of 0.87±0.23 nM for the δ opioid receptor and extremely high selectivity over the µ receptor (IC50=3800±172 nM) and the κ receptor (IC50=7470±606 nM)[1]. RINm5F cells are treated with AR-M 1000390 (AR-M100390) and Cyclizine for 16-24 h before measurement of intracellular and secreted insulin levels. AR-M 1000390 mediates a dose-dependent decrease in insulin content with a maximal inhibition of ~90% at the highest concentration tested (10 μM)[2].
Cell Assay:	RINm5F cells are seeded in 24-well plates and treated with vehicle (DMSO), 10 μM AR-M 1000390 (AR-M100390), and 10 μM Cyclizine in serum-free medium; cells are rinsed with phosphate-buffered saline and stored at -80°C until analysis. RNA is isolated with the RNeasy purification system with DNAse treatment[2].
Animal Administration:	Rats[2] Han Wistar rats (six per treatment group) are treated with vehicle (saline) or 5, 100, and 600 μmol/kg/day of AR-M 1000390 (AR-M100390) for 7 days. A separate group of rats are treated with 600 μmol/kg/day for 7 days followed by a 14-day recovery period. Another group is treated with 600 μmol/kg/day for 3 days. Blood sampling for glucose, lipids, and insulin measurements are taken on days 2, 4, 8, and 22. Blood sampling for AR-M 1000390 concentration measurements are collected on days 4 and 8. The animals are euthanized with CO2 on days 4, 8, and 22 and the pancreas isolated and processed for histopathology, insulin immunohistochemistry, and insulin mRNA analyses[2].

Cat. No.	Product name	Field of application
DC82301	IC-8	IC8 is an ionizable cationic lipid. It has been used in combination with other lipids for the formation of lipid nanoparticles (LNPs). Immunization with severe acute respiratory coronavirus 2 (SARS-CoV-2) spike glycoprotein mRNA in IC8- and manganese-containing LNPs induces IgG responses to SARS-CoV-2 Delta and Omicron variants in mice.1 Administration of mRNA encoding B7-H3 X CD3 bispecific T cell engaging (BiTE) antibodies in IC8-containing LNPs reduces tumor growth in MV4-11 and A375 mouse xenograft models.
DC75721	CL2A-SN38 (Govitecan)	CL2A-SN38 is a SN38 derivative with a peptide-linker which can easily react with antibody to form an antibody-drug conjugate (ADC). CL2A-SN-38 is composed of a potent a DNA Topoisomerase I inhibitor SN-38 and a linker CL2A to make antibody drug conjugate (ADC). CL2A-SN-38 provides significant and specific antitumor effects against a range of human solid tumor types. CL2A is a noncleavable complicated PEG8- and triazole-containing PABC-peptide-mc linker. CL2A is cleavable through pH sensitivity, giving rise to bystander effect, and binds the antibody at a cysteine residue via a disulfide bond. .
DC47877	tri-GalNAc-COOH (acetylation)	tri-GalNAc-COOH acetylation is the acetylated and modified form of tri-GalNAc-COOH. tri-GalNAc-COOH acetylation can be used for the synthesis of LYTAC.
DC46965	Tri-GalNAc-COOH	tri-GalNAc-COOH is an asialoglycoprotein receptor (ASGPR) ligand that can be used for LYsosome TArgeting Chimera (LYTAC) research.
DC46471	RP101988	RP101988, the major active metabolite of Ozanimod, is a selective, potent S1PR1 (sphingosine-1-phosphate receptor 1) agonist, with EC50s of 0.19 nM and 32.8 nM for S1PR1 and S1PR5, respectivlely.
DC37901	PD-173212	PD-173212 is a small molecule N-type calcium channel blocker.
DC37333	N,N-Diethyl-p-toluamide	N,N-Diethyl-p-toluamide is a mosquito repellent.
DC37321	AI3-15902	AI3-15902 is a biochemical.
DC37283	Methyl phenylcarbamate	Methyl phenylcarbamate is a biochemical.
DC37252	Ampyrone	Ampyrone is a metabolite of AMINOPYRINE with analgesic and anti-inflammatory properties. It is used as a reagent for biochemical reactions producing peroxides or phenols. Ampyrone stimulates LIVER MICROSOMES and is also used to measure extracellular water.
