DPDPE is a synthetic enkephalin peptide and ?-opioid receptor agonist (Ki = 2.7 nM in rat brain homogenates).{37712} DPDPE has greater than 250-fold selectivity for the ?-opioid receptor over the ?- and ?-opioid receptors in rat brain homogenates (Kis = 713 and >1,500 nM, respectively). It also selectively inhibits electrically-evoked contractions in mouse vas deferens over guinea pig myenteric plexus (IC50s = 4.14 and 3,000 nM, respectively), which does not express the ?-opioid receptor. In vivo, DPDPE (140 nmol, i.v.) completely blocks tonic hindlimb extension induced by maximal electroshock (MES) in 50% of tested rats and increases the flurothyl-induced seizure threshold by 15-20% in rats, effects that can be blocked by the selective ?-opioid receptor antagonist ICI 154129.{37713} DPDPE (1-10 ?g, i.v) dose-dependently reduces formalin-induced paw licking and lifting, indicating analgesia, in rats.{37714} However, DPDPE (15 ?g, i.v.) increases the latency to tail withdrawal in the tail-immersion test in both wild-type and ?-opioid receptor knockout mice by 6.74 and 7.6 seconds, respectively, compared to a saline control, but not in ?-opioid receptor knockout mice, and the effect can be blocked by the ?-opioid receptor antagonist CTOP.{37715}

Cayman Chemical’s mission is to help make research possible by supplying scientists worldwide with the basic research tools necessary for advancing human and animal health. Our utmost commitment to healthcare researchers is to offer the highest quality products with an affordable pricing policy.
Our scientists are experts in the synthesis, purification, and characterization of biochemicals ranging from small drug-like heterocycles to complex biolipids, fatty acids, and many others. We are also highly skilled in all aspects of assay and antibody development, protein expression, crystallization, and structure determination.
Over the past thirty years, Cayman developed a deep knowledge base in lipid biochemistry, including research involving the arachidonic acid cascade, inositol phosphates, and cannabinoids. This knowledge enabled the production of reagents of exceptional quality for cancer, oxidative injury, epigenetics, neuroscience, inflammation, metabolism, and many additional lines of research.
Our organic and analytical chemists specialize in the rapid development of manufacturing processes and analytical methods to carry out clinical and commercial GMP-API production. Pre-clinical drug discovery efforts are currently underway in the areas of bone restoration and repair, muscular dystrophy, oncology, and inflammation. A separate group of Ph.D.-level scientists are dedicated to offering Hit-to-Lead Discovery and Profiling Services for epigenetic targets. Our knowledgeable chemists can be contracted to perform complete sample analysis for analytes measured by the majority of our assays. We also offer a wide range of analytical services using LC-MS/MS, HPLC, GC, and many other techniques.
