New Imidazole Alkaloids from the Sponge Leucetta chagosensis

Chemical investigation of the sponge Leucetta chagosensis collected in Chuuk State, Federated States of Micronesia, has led to the isolation of two new alkaloids, 2-deoxy-2-aminokealiiquinone (3) and naamine C (5), along with the known alkaloid, pyronaamidine (1). The structures of 3 and 5 were assi...

Description
Summary:Chemical investigation of the sponge Leucetta chagosensis collected in Chuuk State, Federated States of Micronesia, has led to the isolation of two new alkaloids, 2-deoxy-2-aminokealiiquinone (3) and naamine C (5), along with the known alkaloid, pyronaamidine (1). The structures of 3 and 5 were assigned by spectroscopic and chemical methods.
