Squalamine drug synthesis in the laboratory. A pharmaceutical chemist working with squalamine analogs which have been extracted from a synthetic laboratory process. Squalamine is a steroid which has antibacterial properties, and is found in the blood and tissue of dog-fish sharks. This laboratory research is being conducted at Magainin Pharmaceuticals, Pennsylvania, USA, a biotechnology company researching new types of antibiotics. It is hoped that squalamine, produced synthetically, will serve as a natural antibiotic drug. Bacteria which cause human disease are becoming increasingly resistant to all other known antibiotic drugs.
