Screening, Discovery, and Optimization of the Natural Antitubercular Chlorflavonin from a Marine-Derived Fungal Library.
Tuberculosis (TB), caused by the bacterium Mycobacterium tuberculosis (Mtb), is still a leading cause of mortality worldwide. Fifty-fungi from a marine-derived fungal library were screened for anti-Mtb activity, and an Aspergillus candidus strain with strong anti-Mtb activity was found. Three known flavones, chlorflavonin (1), dechlorflavonin (2), and bromoflavone (3), were isolated from this fungus. Chlorflavonin and bromoflavone showed inhibitory activity with MIC90 values of 2.6 and 1.2 μM, respectively. In combination with molecular docking, a series of new chlorflavonin derivatives (4-41) were rationally designed and semisynthesized. Three new derivatives substituted with (2)-chlorocinnamate (14), (3)-chlorocinnamate (15), and benzoate (18) at position 2' showed MIC90 values ranging from 0.7 to 1.0 μM, having the potential to be further explored as antitubercular agents.
期刊介绍:
The Journal of Natural Products invites and publishes papers that make substantial and scholarly contributions to the area of natural products research. Contributions may relate to the chemistry and/or biochemistry of naturally occurring compounds or the biology of living systems from which they are obtained.
Specifically, there may be articles that describe secondary metabolites of microorganisms, including antibiotics and mycotoxins; physiologically active compounds from terrestrial and marine plants and animals; biochemical studies, including biosynthesis and microbiological transformations; fermentation and plant tissue culture; the isolation, structure elucidation, and chemical synthesis of novel compounds from nature; and the pharmacology of compounds of natural origin.
When new compounds are reported, manuscripts describing their biological activity are much preferred.
