Article Synopsis
  • A new series of C-nucleoside analogs based on 2-(D-gulo-) and 2-(D-gluco-)benzimidazole were created by reacting specific compounds, leading to different configurations of these compounds.
  • The structures of these C-nucleoside analogs were confirmed using various scientific techniques, including H NMR and UV spectroscopy.
  • These analogs showed potential antifouling properties by effectively inhibiting marine bacterial growth without harming the surrounding seawater.

Compounds having antimicrobial activity were synthesized from sodium alginate, the main constituent of brown algae. Sodium alginate was oxidized with sodium periodate to get alginate dialdehyde (ADA). FTIR spectrum of the ADA gave very small peak characteristic for aldehyde groups at 1720 cm, indicating that the aldehyde group is masked somehow.

The alginates from five species of brown algae from the Egyptian Red Sea coast, namely: Cystoseira trinode, Cystoseira myrica, Sargassum dentifolium, Sargassum asperifolium, and Sargassum latifolium, were isolated and their compositions and structures studied by 1H NMR spectroscopy. All the alginates studied contain more guluronic acid (G) than mannuronic acid (M) and have a homopolymeric block-type structure (eta<1). The intrinsic viscosity of the alginate samples range from 8.
