Rare Chromones from a Fungal Mutant of the Marine-Derived Penicillium purpurogenum G59
TLDR
The present work explored the great potential of the previous DES mutagenesis strategy for activating silent fungal pathways, which has accelerated the discovery of new bioactive compounds.
Activation of the Dormant Secondary Metabolite Production by Introducing Gentamicin-Resistance in a Marine-Derived Penicillium purpurogenum G59
TLDR
The present study demonstrated the effectiveness of a simple, yet practical approach to activate the production of dormant fungal secondary metabolites by introducing acquired resistance to aminoglycoside antibiotics, which could be applied to the studies for eliciting dormant metabolic potential of fungi to obtain cryptic secondary metabolites.
A new cyclic dipeptide penicimutide: the activated production of cyclic dipeptides by introduction of neomycin-resistance in the marine-derived fungus Penicilliumpurpurogenum G59
TLDR
The present work exemplifies the effectiveness of the previous DMSO-mediated method for introducing drug-resistance in fungi to activate silent biosynthetic pathways to obtain new bioactive compounds.
Purpurogemutantin and Purpurogemutantidin, New Drimenyl Cyclohexenone Derivatives Produced by a Mutant Obtained by Diethyl Sulfate Mutagenesis of a Marine-Derived Penicillium purpurogenum G59
TLDR
Two new drimenyl cyclohexenone derivatives were isolated from a bioactive mutant BD-1-6 obtained by random diethyl sulfate mutagenesis of a marine-derived Penicillium purpurogenum G59, and some silent biosynthetic pathways in the parent strain G59 were demonstrated, including one set for 1–3 production.
A Practical Strategy to Discover New Antitumor Compounds by Activating Silent Metabolite Production in Fungi by Diethyl Sulphate Mutagenesis
TLDR
The effectiveness of this strategy to discover new compounds by activating silent fungal metabolic pathways is demonstrated, and these discoveries provide rationale for the increased use of chemical mutagenesis strategies in silentFungal metabolite studies.
Nine New and Five Known Polyketides Derived from a Deep Sea-Sourced Aspergillus sp. 16-02-1
TLDR
Nine new C9 polyketides, named aspiketolactonol (1), aspilactonols A–F (2–7), aspyronol (9) and epiaspinonediol (11), were isolated together with five known polyketones from the secondary metabolites of an Aspergillus sp.
Activation of Dormant Secondary Metabolite Production by Introducing Neomycin Resistance into the Deep-Sea Fungus, Aspergillus versicolor ZBY-3
TLDR
The present study demonstrated the effectiveness of the ultrasound-mediated approach to activate silent metabolite production in fungi by introducing acquired resistance to aminoglycosides and its potential for discovering new compounds from silent fungal metabolic pathways.
Seven New and Two Known Lipopeptides as well as Five Known Polyketides: The Activated Production of Silent Metabolites in a Marine-Derived Fungus by Chemical Mutagenesis Strategy Using Diethyl
TLDR
It is demonstrated that the production of 1–14 in the mutant AD-2-1 was caused by the activated production of silent metabolites in the original G59 fungal strain.
Chromosulfine, a novel cyclopentachromone sulfide produced by a marine-derived fungus after introduction of neomycin resistance
Chromosulfine (1), a novel cyclopentachromone sulfide, was isolated from a neomycin-resistant mutant of the marine-derived fungus, Penicillium purpurogenum G59. Its structure including
A novel oxaphenalenone, penicimutalidine: activated production of oxaphenalenones by the diethyl sulphate mutagenesis of marine-derived fungus Penicillium purpurogenum G59
A novel oxaphenalenone, penicimutalidine (1), was isolated from a fungal mutant generated through the diethyl sulfate (DES) mutagenesis of marine-derived Penicillium purpurogenum G59 along with three
