A Mononuclear Scenario for the Copper‐Catalyzed Monooxygenation of Phenolic Substrates
Chemistry – A European Journal, EarlyView.ABSTRACT Whereas a dinuclear pathway applies to the monooxygenation of phenols by the type 3 copper enzyme tyrosinase, a mononuclear pathway has been identified for the same reaction in corresponding small‐molecule systems. DFT calculations of five copper model complexes reveal that the latter mechanism is energetically feasible, identifying all ...

Chloramphenicol Acetylation in Streptomyces [PDF]
Journal of General Microbiology, 1976 Twenty-one strains of actinomycetes were screened for the presence of chloramphenicol acetyltransferase, the enzyme responsible for chloramphenicol resistance in many species of bacteria. Only five strains, belonging to three species, yielded mycelial lysates which catalysed the formation of chloramphenicol acetates in the presence of acetyl-coenzyme A:

Total Synthesis of Sacrolide A and Cytotoxic Evaluation
European Journal of Organic Chemistry, EarlyView.Isolated from the edible cyanobacterium Aphanothece sacrum, sacrolide A is a highly potent antimicrobial and cytotoxic metabolite. Its total synthesis via a convergent strategy enabled accurate assessment of its effects on liver and colon cells, offering new insights into its bioactivity and potential health risks.
