Show moreThe work of this dissertation examined the secondary metabolites of several blooms of the marine cyanobacterium Lyngbya collected in Guam and Florida with an emphasis on the isolation and structure elucidation of novel biologically active compounds. The introduction in Chapter One provides a brief history of marine natural products, a description of cyanobacteria and a summary of peptides isolated from Lyngbya collected in the Caribbean. In Chapter Two, a bioassay-guided fractionation of a Floridian collection of Lyngbya polychroa led to the isolation and structural determination of the cytotoxin desacetylmicrocolin B and the known compounds microcolins A and B. The structures were established by nuclear magnetic resonance (NMR) spectroscopic analysis. All three compounds inhibited the growth of cancer cell lines HT-29 and IMR-32 at nanomolar concentrations. Microcolins A and B were found to have little activity in the ecological assay against the marine fungus Dendryphiella salina. Chapter Three describes the isolation and structure elucidation of the glycosidic, acyl proline derivative tumonoic acid J from a sample Lyngbya sp. collected in Guam. The planar structure was determined by 1D and 2D NMR spectroscopy in conjunction with high resolution-mass spectrometry (HR-MS) data. Tumonoic acid J showed moderate activity in the ecological assay against the marine fungus D. salina. In Chapter Four, NMR-guided fractionation of a Floridian sample of Lyngbya majuscula led to the isolation of two novel cyclic peptides porpoisamides A and B. The planar structures were determined by 1D and 2D NMR spectroscopy with HR-MS data. The absolute configurations of these two compounds were defined through chiral chromatographic methods and derivatization techniques., The porpoisamides showed only moderate activity in cytotoxicity assays against cancer cell lines HCT-116 and U2OS. Finally, Chapter Five examines a potential ecological role of compounds isolated from marine cyanobacte ria. These secondary metabolites may function as chemical defenses against competing microorganisms within marine environments. Compounds isolated from cyanobacteria were tested for anti-fungal activity against the saprophytic marine fungus D. salina. Three of the six compounds tested produced inhibitory activity at or below their natural concentration.

Sponges (phylum Porifera) are ancient animals that provide numerous ecosystem functions (e.g., water filtration, habitat, food source) and commercial applications (e.g., bath sponges and pharmaceuticals). However, mass mortality events in Florida Bay have drastically impacted sponge communities and the ecosystem services they provide.

Show moreSponges (phylum Porifera) are ancient animals that provide numerous ecosystem functions (e.g., water filtration, habitat, food source) and commercial applications (e.g., bath sponges and pharmaceuticals). However, mass mortality events in Florida Bay have drastically impacted sponge communities and the ecosystem services they provide. To restore habitats, sponge restoration initiatives are ongoing in Florida. The aim of this thesis was to determine survival and growth of sponges in a land-based nursery. Larvae from four species were collected from the Indian River Lagoon and the Florida Keys from July to September 2021. Larval settlement and metamorphosis, survival of recruits, morphological development and growth were observed, quantified, and compared to other species. Larvae settlement success was highest in our Heteroscleromorpha species Tedania ignis, Haliclona caerulea and Niphates erecta, but not the Keratosa species Spongia sp. However, the highest recruit survival was the Spongia sp. Early developmental characteristics were significantly different among species and over observation periods, with most developmental characteristics occurring during the first 14 days post-settlement. H. caerulea and Spongia sp. developed faster than other species. Spongia sp. recruit growth was higher when kept in artificial seawater with no food supplement. These results provide further insight toward optimizing the FAUHBOI sponge nursery protocols to supplement current restoration efforts and increase the abundance of sponge populations and community diversity.

Show moreThe projects described in this dissertation are focused on compounds derived from the marine environment. Chapter 1 gives an introduction to the study of marine natural products to treat human ailments and a thorough review on compounds from lithistid sponges that have been isolated or synthesized since 2000. Chapter 2 describes the isolation and structure elucidation of two sesquiterpene substituted benzoquinone derivatives, petrosiquinones A and B, from a deep-water marine sponge from the Family Petrosiidae. Although initially purified following activity in a (Sb(B-catenin/Tcf4 assay they were later followed using tumor cell line cytotoxicity assays. Petrosiquinone A was the more active of the two compounds with moderate cytotoxicity in the DLD-1, PANC-1, and AsPC-1 cell lines. In Chapter 3, the isolation and structure elucidation of two new marine-derived macrolides, madeirolide A and B, isolated from a deep-water lithistid sponge of the genus Leiodermatium is described., They were isolated using numerous chromatographic techniques and the structures were elucidated on the basis of 1D and 2D NMR spectra coupled with high resolution-mass spectrometry (HR-MS) data. Madeirolide A and B inhibited the growth of the fungal pathogen Candida albicans with minimum inhibitory concentrations (MIC) of 12.5 and 25 (So(Bg/mL, respectively, but were not cytotoxic in tumor cell assays under the conditions tested. Chapter 4 describes work performed to determine the molecular target of lasonolide A using affinity chromatography. The target of lasonolide A is of interest since lasonolide A is known to kill cancer cells in vitro through a unique mechanism., This chapter highlights the research performed to create an affinity matrix with immobilized lasonolide. A target has not been confirmed but there are a number of interesting hits that are being pursued. In Chapter 5, a liquid chromatography-mass spectrometry (LC-MS) screening method was established in order to rapidly identify the metabolites from numerous collections of Lyngbya spp. obtained from Broward and Lee County, Florida sites that may help marine ecologists assess the effects of Lyngbya spp. blooms on the environment. A link between the metabolites produced and nutrients from both the algal tissue and water column was also explored.

The project detailed in this thesis focuses on the extraction of compounds from marine invertebrates as well as defining the absolute configuration for a compound. Utilizing marine invertebrates, the sonications method developed in this thesis provides an alternative approach to rapidly extract compounds for primary screening. This method is viable compared to a traditional overnight extraction method, without suffering compound degredation... Previously, clathric acid was isolated from an unknown Clathria sp. This compound is a bibyblic C-21 terpenoid shown to have mild antimicrobial activity against gram positive bacteria. With only its relative configuration established, additional amounts of clathric acid were required to define the overall absolute configuration. Identifying the Clathria sp. to be Clathria compressa, through spicule analysis, additional sponge tissues were then collected off the coast of Boca Raton, Florida to isolate additional quatities of clathric acid. The absolulte configuration was determined through circular dichroism and the octant rule to establish a final configuration for clathric acid's four carbon stereocenters to be: (3S, 7S, 8R, and 12S).

Abstract/Description
Sponges (Phylum Porifera) are hardy organisms persisting and predicted to become more dominant world-wide under climate change scenarios. However, we lack baseline knowledge on sponge biodiversity in transitional areas (subtropical to warm-temperate) that are more susceptible to climate change such as The Indian River Lagoon (IRL) (estuary) and Saint Lucie Reef (northern most coral reef) ecosystems in south Florida.

Show moreSponges (Phylum Porifera) are hardy organisms persisting and predicted to become more dominant world-wide under climate change scenarios. However, we lack baseline knowledge on sponge biodiversity in transitional areas (subtropical to warm-temperate) that are more susceptible to climate change such as The Indian River Lagoon (IRL) (estuary) and Saint Lucie Reef (northern most coral reef) ecosystems in south Florida. The aims of this master’s thesis are to 1) evaluate if sponge assemblages reflect the previously defined ecotone between subtropical and warm-temperate biomes in the IRL (Chapter one), 2) determine how porifera communities are associated to their respective environment (temperature, water velocity, photosynthetically active radiation, carbonate chemistry, and nutrients) in the IRL and St. Lucie Reef (Chapter two), and 3) establish a distribution baseline for future studies aiming to assess Porifera range shifts during climate change (Chapter one and two). Porifera biodiversity surveys across the IRL and Saint Lucie reef were carried out at different spatial and time scales. Environmental parameters (ocean acidification, temperature and eutrophication) were obtained and compared for sites in Fort Pierce Inlet and St Lucie Reef. Chapter one results show that sponge assemblages do not reflect the previously defined ecotone between subtropical and warm-temperate biomes in the IRL, instead they structure in relation to the inlets (distance from the inlet). The most diverse sponge assemblages are found in Sebastian, Fort Pierce, and Jupiter Inlets, and are significant different among habitats; oyster reefs host a unique assemblage of excavating sponges.
