SEMINARIO BIOMEDICO  “Diving in the microbial genomes to obtain new natural drugs


Tuesday, March 14, 2024
From 9:30 to 10:30


Microbial Natural Products (NPs) exhibit a wide range of biomedical activities, including antibacterial, antitumoral, immunosuppressive, anticholesteremic, and antiparasitic. The field of NPs research has faced numerous challenges; however, the advent of the «-omics» revolution has breathed new life into this area. This revitalization is exemplified by the research on the NPs, Nataxazole, Ferrocins, and Cyclosporine. Nataxazole is an antitumoral produced by Streptomyces sp. Tü 6176, which exhibits activity against multiple antitumoral cell lines. The biosynthesis characterization through genome mining and genetic engineering entailed the discovery of AJI9561 as the biosynthetic final product and demonstrated the first crosstalk between two pathways to produce the drug UK-1. On the other hand, ferrocins, non-ribosomal lipopeptides, were described produced by Pseudomonas sp. Despite their excellent antibacterial activity, their low production impeded their development. Characterizing the biosynthetic gene cluster provided clues to enhance their yield, and the heterologous expression of the resistance gene shed light on their uncommon mode of action. Finally, the immunosuppressor Cyclosporine, another non-ribosomal peptide, is produced by the filamentous fungus Tolypocladium inflatum. Its discovery revolutionized organ transplant and autoimmune disease treatment. Nevertheless, its synthetic chemistry is laborious and expensive. Here, the application of the diverse “-omics,” Synthetic Biology tools, and heterologous expression are guiding us towards a more biosustainable and likely more affordable production approach.
