The antialgal activity of a number of simple phenols was examined for their effect on the growth of 7 species of unicellular marine algae. The 3 knoiun algal phenols, 5-bromo-3,4-dihydroxybenzaldehyde; 2,3-dibromo-4,5-dihydroxybenzylalcohol, and 3,4-dihy-droxyphenylethylamine, were highly toxic as were other ortho dihydroxy compounds. Monohydroxy compounds were notably less toxic. Skeletonema costatum and Olisthodiscus sp. were the most sensitive organisms examined and Dunaliella tertiolecta was the most resistant. Possible ecological implications of these results are discussed.

Chemical quantification of N-acyl alanine methyl ester (NAME) production and impact on temporal gene expression patterns in Roseovarius tolerans EL-164.

Background: Previous studies have identified structurally diverse N-acyl amino acid methyl esters (NAMEs) in culture extracts of Roseovarius tolerans EL-164 (Roseobacteraceae). NAMEs are structural analogues of the common signaling compounds N-acyl homoserine lactones (AHLs), but do not participate in AHL-mediated signaling. NAMEs show minor antialgal and antimicrobial activity, but whether this activity serves as the primary ecological role remains unclear.

Article Synopsis
- Biological fouling poses a significant threat to the marine industry, causing damage to installations and aquaculture due to attached microorganisms and microcontaminants.
- Researchers introduced polyhexamethylene-biguanide (PHMB) and MXene into carboxylated cellulose nanofibers reinforced polyvinyl alcohol (PVA) hydrogel to create a tough, self-healing antifouling material.
- The resulting double network (DN) hydrogels demonstrate exceptional antifouling properties, remaining effective for over six months, with high toughness, anti-protein and anti-algal adhesion, and strong antibacterial activity.
1,2,4-Triazolo-quinazolinones as Effective Antifoulants: Molecular Design, Synthesis, and Biological Evaluation.

A series of 1,2,4-triazolo-quinazolinones and 1,2-benzisothiazolone derivatives (S1-S12) were successfully synthesized as environmentally friendly alternatives to copper-based antifouling paints using -alkylation, cyclocondensation, and one-pot three-component and amide coupling reactions. The monoclinic structure of single-crystal 1,2,4-triazolo-quinazolin-acetic acid (S8) was confirmed by single-crystal X-ray diffraction analysis. All the synthesized molecules were studied for their in silico molecular docking interactions with three target proteins, namely, RbmA, ToxR, and Bap.
