yuremamine yuremamine yuremamine is a phytoindole alkaloid which was isolated from the bark of mimosa tenuiflora in 2005, and erroneously assigned a pyrroloindole structure that was thought to represent a new class of indole alkaloids. however, in 2015, the bioinspired total synthesis of yuremamine revealed its structure to be a flavonoid derivative. it was also noted in the original isolation of yuremamine that the alkaloid occurs naturally as a purple solid, but total synthesis revealed that yuremamine as a free base is colorless, and the formation of a trifluoroacetate salt during hplc purification is what led to the purple appearance. originally proposed chemical structure of yuremamine yuremamine names other names yuremamine identifiers cas number 883973-98-6 n 3d model (jsmol) interactive image chemspider 62702341 pubchem cid 122386737 inchi inchi=1s/c27h28n2o6/c1-29(2)10-9-17-16-5-3-4-6-19(16)28-24(17)23-18-8-7-15(30)13-22(18)35-27(26(23)34)14-11-20(31)25(33)21(32)12-14/h3-8,11-13,23,26-28,30-34h,9-10h2,1-2h3/t23-,26+,27-/m0/s1key: kxdxqdytlnrchp-rnjdceswsa-n smiles cn(c)ccc1=c(nc2=cc=cc=c12)1(o)(oc2=c1c=cc(o)=c2)c1=cc=cc=c1 properties chemical formula c27h28n2o6 molar mass 476.529 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
