Tedaniophorbasins A and B-Novel Fluorescent Pteridine Alkaloids Incorporating a Thiomorpholine from the Sponge Tedaniophorbas ceratosis. Mar Drugs 2021; 19:md19020095. [PMID: 33562248 PMCID: PMC7915533 DOI: 10.3390/md19020095] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2021] [Revised: 02/02/2021] [Accepted: 02/03/2021] [Indexed: 11/30/2022] Open
Abstract
Two new fluorescent pteridine alkaloids, tedaniophorbasins A (1) and B (2), together with the known alkaloid N-methyltryptamine, were isolated, through application of mass directed purification, from the sponge Tedaniophorbas ceratosis collected from northern New South Wales, Australia. The structures of tedaniophorbasins A and B were deduced from the analysis of 1D/2D NMR and MS data and through application of 13C NMR DFT calculations. Tedaniophorbasin A possesses a novel 2-imino-1,3-dimethyl-2,3,7,8-tetrahydro-1H-[1,4]thiazino[3,2-g]pteridin-4(6H)-one skeleton, while tedaniophorbasin B is its 2-oxo derivative. The compounds show significant Stokes shifts (~14,000 cm−1) between excitation and emission wavelengths in their fluorescence spectra. The new compounds were tested for bioactivity against chloroquine-sensitive and chloroquine-resistant strains of the malaria parasite Plasmodium falciparum, breast and pancreatic cancer cell lines, and the protozoan parasite Trypanosoma brucei brucei but were inactive against all targets at 40 µM.

Abstract
The importance of pteridines in the key cofactors, tetrahydrofolate and tetrahydrobiopterin, has encouraged the development of the chemistry and chemical biology of pteridines. In order to investigate the latter, versatile synthetic methods are required to prepare designed relatives of the natural cofactors for use as potential drugs or biological probes. Recently, diversity-oriented synthesis has become a particularly powerful and versatile approach to the synthesis of pteridines and related heterocyclic compounds. This article describes and discusses available methods using radical, electrophilic, nucleophilic, and organometal mediated substitution reactions.
