dadle dadle dadle (-enkephalin) is a synthetic opioid peptide with analgesic properties. although it is often considered a selective delta opioid receptor agonist, it also binds to the μ1 subtype of mu opioid receptors. dadle names iupac name (2r)-2-amino]propanoyl]amino]acetyl]amino]-3-phenylpropanoyl]amino]-4-methylpentanoic acid other names • -enkephalin• l-tyrosyl-d-alanylglycyl-l-phenylalanyl-d-leucine• n-(n-(n-(n-l-tyrosyl-d-alanyl)glycyl)-l-phenylalanyl)-d-leucine• tyr-d-ala-gly-phe-d-leu-oh identifiers cas number 63631-40-3 y 3d model (jsmol) interactive image chemspider 5292936 n echa infocard 100.059.337 pubchem cid 6917707 unii hb4qd9gl6f y inchi inchi=1s/c29h39n5o7/c1-17(2)13-24(29(40)41)34-28(39)23(15-19-7-5-4-6-8-19)33-25(36)16-31-26(37)18(3)32-27(38)22(30)14-20-9-11-21(35)12-10-20/h4-12,17-18,22-24,35h,13-16,30h2,1-3h3,(h,31,37)(h,32,38)(h,33,36)(h,34,39)(h,40,41)/t18-,22+,23+,24-/m1/s1 nkey: zhujmsmqipiptf-iburtvsxsa-n ninchi=1/c29h39n5o7/c1-17(2)13-24(29(40)41)34-28(39)23(15-19-7-5-4-6-8-19)33-25(36)16-31-26(37)18(3)32-27(38)22(30)14-20-9-11-21(35)12-10-20/h4-12,17-18,22-24,35h,13-16,30h2,1-3h3,(h,31,37)(h,32,38)(h,33,36)(h,34,39)(h,40,41)/t18-,22+,23+,24-/m1/s1key: zhujmsmqipiptf-iburtvsxbs smiles n(c(n(c)c(ncc(n(cc1=cc=cc=c1)c(n(cc(c)c)c(o)=o)=o)=o)=o)=o)cc2=cc=c(o)c=c2 properties chemical formula c29h39n5o7 molar mass 569.659 g·mol−1 except where otherwise noted, data are given for materials in their standard state (at 25 °c , 100 kpa). n verify (what is yn ?) infobox references treatment with dadle results in transient depression of mean arterial blood pressure and heart rate. its peptide sequence is tyr-d-ala-gly-phe-d-leu.
