roseophilin roseophilin roseophilin is an antibiotic isolated from streptomyces griscovirides shown to have antitumor activity. the chemical structure can be considered in terms of two components, a macrotricyclic segment and a heterocyclic side-chain. several laboratory syntheses of roseophilin (e.g., those of trost, fürstner, salamone) are based upon the paal-knorr synthesis, and two others are based on the nazarov cyclization reaction (those of tius, frontier). the compound is related to the prodiginines. roseophilin names iupac name 15--13-isopropyl-2-aza-tricyclohexadeca-1(15),2-triene identifiers cas number 142386-38-7 n 3d model (jsmol) interactive image chembl chembl1945189 n chemspider 4578301 y pubchem cid 5467324 comptox dashboard (epa) dtxsid20745446 inchi inchi=1s/c27h33cln2o2/c1-16(2)23-18-11-9-7-5-4-6-8-10-17-14-19(23)25(30-17)24(18)27-22(31-3)15-21(32-27)26-20(28)12-13-29-26/h12-16,18,23,30h,4-11h2,1-3h3/b26-21-,27-24- ykey: xeqixgxebjynmg-olpwbvpvsa-n yinchi=1/c27h33cln2o2/c1-16(2)23-18-11-9-7-5-4-6-8-10-17-14-19(23)25(30-17)24(18)27-22(31-3)15-21(32-27)26-20(28)12-13-29-26/h12-16,18,23,30h,4-11h2,1-3h3/b26-21-,27-24-key: xeqixgxebjynmg-olpwbvpvbq smiles cc(c)1\2ccccccccc3=cc1=c(/c2=c\4/c(=c/c(=c/5\c(=cc=n5)cl)/o4)oc)n3 properties chemical formula c27h33cln2o2 molar mass 453.02 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
