Antibacterial bromophenols from the marine red alga Rhodomela confervoides

Halogenated Organic Molecules of Rhodomelaceae Origin: Chemistry and Biology

“…384 Of these, compound 674 showed potent inhibitory activity against seven out of eight strains, especially against S. epidermidis ATCC12228, whereas 650 displayed moderate activity against four strains. 384 More recently, bromophenol 649 was reported to have activity against five bacterial strains (S. aureus ATCC6538p, Bacillus subtilis ATCC 6633, Micrococcus luteus IFC 12708, Proteus vulgaris ATCC3851, and S. typhimurium ATCC 14028) with MIC values ranging from 25 to 50 μg/ mL. 505 At a level of 100 μg per 12.7 mm disc, 2,3,5,6-tetrabromoindole (573) displayed an inhibition zone of 16 mm against Bacillus subtilis after 24 h of growth.…”

Applications of Immunostimulants in Aquaculture: A Review

“…The under utilization of the shrimp head waste posing a serious disposal problem, contributes to the overall cost of the production. One of the possible solutions of this problem is to transform processing waste into either silage or flour and use this material in the formulation of animal or fish feeds (Xu et al, 2003).…”

Seaweeds as Source of New Bioactive Prototypes

“…The BPs are known to have various biological activities [111]. best results [112]. Inhibiting the activity of the enzyme Glucose-6-phosphate dehydrogenase also was described by BPs [113].…”
