felypressin felypressin felypressin is a non-catecholamine vasoconstrictor that is chemically related to vasopressin, the posterior pituitary hormone. it is added to some local anaesthetics such as prilocaine in a concentration of 0.03 iu/ml. felypressin is a vasopressin 1 agonist, and will thus have effects at all arginine vasopressin receptor 1as. it will, however, have its main physiological effects on vascular smc's due to the form in which it is administered. felypressin names iupac name 1--pyrrolidine-2-carboxylic acid -amide identifiers cas number 56-59-7 y 3d model (jsmol) interactive image chebi chebi:60564 y chembl chembl1697764 n chemspider 16736539 y drugbank db00093 y echa infocard 100.000.257 pubchem cid 5956 unii 17n2918v6g y comptox dashboard (epa) dtxsid6048599 inchi inchi=1s/c46h65n13o11s2/c47-18-8-7-14-29(40(64)52-23-38(51)62)54-45(69)35-15-9-19-59(35)46(70)34-25-72-71-24-28(48)39(63)55-31(20-26-10-3-1-4-11-26)43(67)56-32(21-27-12-5-2-6-13-27)42(66)53-30(16-17-36(49)60)41(65)57-33(22-37(50)61)44(68)58-34/h1-6,10-13,28-35h,7-9,14-25,47-48h2,(h2,49,60)(h2,50,61)(h2,51,62)(h,52,64)(h,53,66)(h,54,69)(h,55,63)(h,56,67)(h,57,65)(h,58,68)/t28-,29-,30-,31-,32-,33-,34-,35-/m0/s1 ykey: sfkqvvdkfkytna-dzcxqceksa-n yinchi=1/c46h65n13o11s2/c47-18-8-7-14-29(40(64)52-23-38(51)62)54-45(69)35-15-9-19-59(35)46(70)34-25-72-71-24-28(48)39(63)55-31(20-26-10-3-1-4-11-26)43(67)56-32(21-27-12-5-2-6-13-27)42(66)53-30(16-17-36(49)60)41(65)57-33(22-37(50)61)44(68)58-34/h1-6,10-13,28-35h,7-9,14-25,47-48h2,(h2,49,60)(h2,50,61)(h2,51,62)(h,52,64)(h,53,66)(h,54,69)(h,55,63)(h,56,67)(h,57,65)(h,58,68)/t28-,29-,30-,31-,32-,33-,34-,35-/m0/s1key: sfkqvvdkfkytna-dzcxqcekbi smiles nc(=o)cnc(=o)(ccccn)nc(=o)1cccn1c(=o)4nc(=o)(nc(=o)(ccc(n)=o)nc(=o)(cc2ccccc2)nc(=o)(cc3ccccc3)nc(=o)(n)cssc4)cc(n)=o properties chemical formula c46h65n13o11s2 molar mass 1040.22 g/mol 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 v1 receptors are found in various sites around the body. the major points include the cns, liver, anterior pituitary, muscle (both vascular and non-vascular smooth muscle), and platelets (clamp). another example of a v1 agonist is terlipressin - which is used in oesophageal varices.
