“…The extract of Ircinia felix was found to be the most potent inhibitor of quorum-sensing with the activity linked to the felixinin furanosesquiterpenoid class. [708][709][710] Chemical examination of adult and bud larvae of the chemically-defended sponge Tethya maza indicated that the sterol composition of both were largely similar, suggesting that the larvae are also defended during reproduction. 711 First total syntheses were reported for many compounds including the lipids motualevic acid F, (E)-and (Z)-antazirine, [712][713][714] mycalol (revised to 1105) [715][716][717] and myrmekioside A, 718,719 and polyacetylenes callyspongynic acid, 720,721 phosphoiodyn A and placotylene A.…”

“…Known compounds that have been demonstrated to inhibit the bacterial QS system include p -coumaric acid from garlic extract27, methyl eugenol from Cuminum cyminum 28, baicalein from Scutellaria baicalensis 29, curcumin from Curcuma longa 30, maniwamycins from Streptomyces sp 31,. unidentified secondary metabolites from marine Streptomyces 32, furanosesterterpenes from the marine sponge Ircinia felix 33, sesqui- and triterpenoids from the liverwort Lepidozia chordulifera 34, and unidentified components from edible mushrooms3536.…”

“…Compound (7 Z ,13 Z ,18 R ,20 Z )-felixinin acetate ( 37 ), (8 Z ,13 Z ,18 R ,20 Z )-strobilinin acetate ( 38 ), (7 E ,13 Z ,18 R ,20 Z )-felixinin acetate ( 39 ) and (8 E ,13 Z ,18 R ,20 Z )-strobilinin acetate ( 40 ) was isolated with distinct configuration along with compound (7 E ,12 E ,18 R ,20 Z )-variabilin acetate ( 41 ) using C. violaceum biosensor [43]. These compounds were previously reported from I. felix based on their antimicrobial properties [94,95].…”
