Patents on Endophytic Fungi Related to Secondary Metabolites and Biotransformation Applications

Journal of Fungi, 2020
Endophytic fungi are an important group of microorganisms and one of the least studied. They enhance their host’s resistance against abiotic stress, disease, insects, pathogens and mammalian herbivores by producing secondary metabolites with a wide ...

Amide and Thioester Synthesis Via Oxidative Coupling of Alcohols with Amines or Thiols Using Alcohol Dehydrogenases

Angewandte Chemie, EarlyView.
Alcohol dehydrogenases (ADHs) are best known for reducing ketones to chiral alcohols, but their oxidative potential is rarely exploited. Here, we show that selected ADHs catalyze newly discovered promiscuous transformations: the oxidative coupling of primary alcohols with amines or thiols, enabling the direct and efficient synthesis of a broad range of

Biocatalytic preparation and absolute configuration of enantiomerically pure fungistatic anti-2-benzylindane derivatives. Study of the detoxification mechanism by Botrytis cinerea [PDF]

, 2010
Enantiomerically pure 2-benzylindane derivatives were prepared using biocatalytic methods and their absolute configuration determined. (1R,2S)-2-Benzylindan-1-ol ((1R,2S)-2) and (S)-2-benzylindan-1-one ((S)-3) were produced by fermenting baker’s yeast.

Inactivation of the Burkholderia Toxin Malleicyprol by Enzymatic Cyclopropanol Ring Opening

Angewandte Chemie, EarlyView.
Burkholderia pseudomallei and Burkholderia mallei are dangerous pathogens that cause severe diseases with high mortality rates. Their virulence relies in part on malleicyprols, potent toxins containing a highly reactive cyclopropanol group. In this study, we identify BurK, a heme‐dependent oxidoreductase that neutralizes malleicyprols by enzymatically ...

Heterocycles 36. Single-Walled Carbon Nanotubes-Bound N,N-Diethyl Ethanolamine as Mild and Efficient Racemisation Agent in the Enzymatic DKR of 2-Arylthiazol-4-yl-alanines

Molecules, 2015
In this paper we describe the chemoenzymatic synthesis of enantiopure l-2-arylthiazol-4-yl alanines starting from their racemic N-acetyl derivatives; by combining the lipase-catalysed dynamic kinetic resolution of oxazol-5(4H)-ones with a chemical and an

Mycotoxins: Biotransformation and Bioavailability Assessment Using Caco-2 Cell Monolayer

Toxins, 2020
The determination of mycotoxins content in food is not sufficient for the prediction of their potential in vivo cytotoxicity because it does not reflect their bioavailability and mutual interactions within complex matrices, which may significantly alter ...

Printed Integrated Logic Circuits Based on Chitosan‐Gated Organic Transistors for Future Edible Systems

Advanced Functional Materials, EarlyView.
Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...
