4-HYDROXYMELLEIN CAS号: 33788-22-6 英文名: 4-HYDROXYMELLEIN 英文别名: 4-HYDROXYMELLEIN;4-Hydroxychracin;3-Methyl-4,8-dihydroxyisochroman-1-one;3,4-Dihydro-4,8-dihydroxy-3-methyl-1H-2-benzopyran-1-one;1H-2-Benzopyran-1-one, 3,4-dihydro-4,8-dihydroxy-3-methyl- ...
One such isocoumarin derivative, 4-hydroxymellein, has been previously isolated in marine-derived fungi and found to exhibit antimicrobial activity. 4-hydroxymellein has also been found in the ant Camponotus quadrisectus F. Smith, but this isocoumarin has not been synthesized. This presentation ...
An analysis of the volatile components of the ant collected in Brunei showed the presence of 2-ethyl-2-hexen-1-ol (1) and 4-hydroxymellein (2), previously undetected in insects, as major components. The phenolic acetogenins m-cresol, 6-methyl salicylic acid, and mellein were also present...

6-Methoxymellein (6-MM) is the carrot phytoalexin and 6-hydroxymellein (6-HM) its immediate biosynthetic precursor. 6-MM is more toxic than 6-HM to the producing carrot cells, as demonstrated by the differential toxicity of these two dihydroisocoumarins to either colony forming units in ...
