AI Article Synopsis

  • - Two new alkaloids, spongimides A and B, were isolated from a marine sponge species, along with five known alkaloids.
  • - The structures of spongimides A and B were determined using various analytical methods, including UV, IR, MS, NMR, and X-ray diffraction.
  • - Compounds A and B represent the first instances of 2,4-imidazolidinediones found in this sponge genus, and their cytotoxic and antibacterial properties were tested.

Article Abstract

Two new alkaloids, spongimides A () and B (), along with five known ones (-), were isolated from the marine sponge sp. The structures of and were determined by the spectroscopic methods (UV, IR, MS, and NMR) and X-ray diffraction analysis. Compounds , , and were the first examples of 2,4-imidazolidinediones isolated from this genus. In addition, the cytotoxic and antibacterial activities of compounds and were also evaluated.
