cilofungin cilofungin cilofungin (inn) is the first clinically applied member of the echinocandin family of antifungal drugs. it was derived from a fungus in the genus aspergillus. it accomplishes this by interfering with an invading fungus' ability to synthesize the cell wall (specifically, it inhibits the synthesis of (1→3)-β-d-glucan). cilofungin names iupac name n--11,20,21,25-tetrahydroxy-3,15-bis(1-hydroxyethyl)-26-methyl-2,5,8,14,17,23-hexaoxo-1,4,7,13,16,22-hexaazatricycloheptacosan-18-yl]-4-(octyloxy)benzamide other names 1--l-ornithine]echinocandin b (4r,5r)-4,5-dihydroxy-n2--l-ornithyl-l-threonyl-trans-4-hydroxy-l-prolyl-(s)-4-hydroxy-4-(p-hydroxyphenyl)-l-threonyl-l-threonyl-(3s,4s)-3-hydroxy-4-methyl-l-proline cyclic (6→1)-peptide identifiers cas number 79404-91-4 y 3d model (jsmol) interactive image chembl chembl2103748 n chemspider 5293334 n mesh cilofungin pubchem cid 6918120 unii 8zjc54a39x y inchi inchi=1s/c49h71n7o17/c1-5-6-7-8-9-10-19-73-31-17-13-28(14-18-31)42(65)50-32-21-34(61)45(68)54-47(70)38-39(62)24(2)22-56(38)49(72)36(26(4)58)52-46(69)37(41(64)40(63)27-11-15-29(59)16-12-27)53-44(67)33-20-30(60)23-55(33)48(71)35(25(3)57)51-43(32)66/h11-18,24-26,30,32-41,45,57-64,68h,5-10,19-23h2,1-4h3,(h,50,65)(h,51,66)(h,52,69)(h,53,67)(h,54,70)/t24-,25+,26+,30+,32-,33-,34+,35-,36-,37-,38-,39-,40-,41-,45+/m0/s1 nkey: zkzkceahvfvzdj-mtumarhdsa-n ninchi=1/c49h71n7o17/c1-5-6-7-8-9-10-19-73-31-17-13-28(14-18-31)42(65)50-32-21-34(61)45(68)54-47(70)38-39(62)24(2)22-56(38)49(72)36(26(4)58)52-46(69)37(41(64)40(63)27-11-15-29(59)16-12-27)53-44(67)33-20-30(60)23-55(33)48(71)35(25(3)57)51-43(32)66/h11-18,24-26,30,32-41,45,57-64,68h,5-10,19-23h2,1-4h3,(h,50,65)(h,51,66)(h,52,69)(h,53,67)(h,54,70)/t24-,25+,26+,30+,32-,33-,34+,35-,36-,37-,38-,39-,40-,41-,45+/m0/s1key: zkzkceahvfvzdj-mtumarhdbf smiles o=c2n5(c(=o)n(o)(o)c(nc(=o)c1ccc(occcccccc)cc1)c(=o)n(c(=o)n4(c(=o)n(c(=o)n2(o)c)(o)(o)c3ccc(o)cc3)c(o)c4)(o)c)(o)(c)c5 properties chemical formula c49h71n7o17 molar mass 1030.12474 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
