Solid Tumor Anticancer Drug Discovery from Tropical Marine Cyanobacteria

Emily Mevers

Appointment Period: 2011-2013, Grant Years: [27,28]

Emily MeversMarine algae and cyanobacteria are extremely rich sources of structurally diverse natural products, some of which have potent biological properties of relevance to cancer treatment. These samples, collected under permits from various foreign countries, are available as screening sets for human lung cancer cytotoxicity screens. As active materials are found from screening, I apply state-of-the-art chromatographic expertise to separate these into single components which are then returned to the bioassay for evaluation. Ultimately, this process leads to pure and active compounds which I then apply contemporary approaches in 2DNMR and Mass Spectrometry to solve their sometimes quite complicated structures. I fully expect that some of my research projects will develop such that I become involved in determining the site of action of one of my more potent anticancer-type molecules.
