An iterative cross-coupling based approach to the synthesis of peridinin and progress towards peridinin derivatives
… potential to serve as powerful pharmaceuticals. Peridinin, an atypical carotenoid found in dinoflagellates responsible for the color of red tide, is especially interesting as a potential antilipoperoxidant because it may act through self-preserving mechanisms, unlike other carotenoids. We report …

Modular synthesis-enabled mechanistic characterization of the potent antilipoperoxidant activity of peridinin
… platform, the structurally atypical carotenoid peridinin was found to be a potent inhibitor of non-enzymatic bilayer lipid peroxidation. With the goal of maximizing the utility of peridinin as a small molecule probe of the role of lipid peroxidation in pathogenesis, the mechanistic underpinnings …

Synthesis, biological activity and mechanism of atypical carotenoid antilipoperoxidants
… activity of three highly atypical carotenoids, peridinin, synechoxanthin, and chlamydaxanthin. We synthesized each of these natural products utilizing an efficient and modular building block based approach. This strategy allowed for initial activity assays as well synthesis of isotopically …

Optimisation of high value metabolite production from benthic marine dinoflagellate Prorocentrum lima.
… lima. The organism is also known to produce peridinin, a carotenoid pigment that has been found to have pharmaceutical potential. Results from this study showed that cultivation of P. lima CCAP 1136/11 was still, although not completely, reliant on supply of natural seawater. Characterisation …

Photophysical transformations in molecules studied by ultrafast multi-pulse spectroscopy /
… observed. Second, another chapter is devoted to peridinin-chlorophyll-a protein (PCP), which is a light-harvesting protein with complex excited state dynamics. Within the protein complex, carotenoid peridinin absorbs the radiation and transfers the excitation energy to chlorophyll-a. The exact …

Total synthesis and study of the antilipoperoxidant peridinin, synthesis of versatile MIDA boronate building blocks, and a general strategy for the synthesis of polyenes
… synthesis of the carotenoid natural product peridinin. This natural product inspired the development of new methodology, including the stereocontrolled Suzuki-Miyaura cross-coupling of haloallenes and the transesterification of boronic esters to MIDA boronates and MIDA boronates to boronic …

Computational simulations of excitation energy transfer and electron transfer in biological systems
… the context of characterizing excited states of peridinin. Subsequently, the obtained energetic parameters for peridinin, as well as chlorophyll, were further used to construct an excitonic Hamiltonian model for the system. The second direction concerns the development of eMap 2.0, an open-source …

The Assimilation of Glucose by Phytoplankton: A Potentially Common Adaptation Under Multiple Irradiance and Field Conditions
… phytoplankton (chlorophyll a, fucoxanthin, peridinin,). Assimilation varied inversely with irradiance and growth was stimulated in the dark with glucose addition. The ability of the phytoplankton to assimilate glucose in the dark and light has potential implications for the microbial loop …

THE ORIGIN OF THE DINOFLAGELLATE PLASTID
The peridinin pigmented dinoflagellate chloroplasts are the result of a secondary endosymbiotic event between a photosynthetic eukaryote and a dinoflagellate. Dinoflagellate chloroplast and nuclear evolution were independent before this endosymbiotic event. To reconstruct the evolution of the …

Quantum Physics of Photosynthetic Light -Harvesting
… purple bacterium Rhodospirillum molischianum and peridinin-chlorophyll protein of the dinoflagellate Amphidinium carterae. The electronic excitations of carotenoids and BChls have been described by means of semi-empirical self-consistent-field configuration interaction calculations. The electronic …

Ultraviolet Radiation and Carotenoid Pigmentation in Symbiotic Anthozoans
… pressure liquid chromatography (HPLC) included peridinin, diadinoxanthin, diatoxanthin and (3-carotene. In <strong>CHAPTER III</strong>, I show that including a carotenoid-rich diet of <em>Artemia</em>nauplii has no effect on the carotenoid composition of <em>A. pallida</em>. However, a 2-way …
