A series of eugenol derivatives (2-14) were synthesized and evaluated for their antibacterial activity against five bacterial test strains; three Gram-positive bacteria (Bacillus subtilis, Staphylococcus aureus and Staphylococcus epidermidis) and two Gram-negative bacteria (Escherichia coli and Salmonella typhimurium) using well-diffusion method. Among the compounds tested, compounds 2-4 displayed susceptible activity toward S. epidermidis with 16-18 mm whereas compounds 12 exhibited susceptible inhibition towards S. aureus only with inhibition diameter of 16 mm, respectively. Other compounds possessed varied antibacterial activities classified as intermediate or resistance indicating that eugenol derivatives have narrow spectrum activity and specifically to Gram-positive bacteria.

appears to be interesting for the development of new antimicrobials. This study aimed to evaluate the antimicrobial activity and cytotoxic characteristics of eugenol analogs. From natural eugenol, 14 derivatives were obtained by typical acylation and alkylation. Their antimicrobial activity was evaluated by the broth microdilution method. The compounds were assessed against Staphylococcus aureus ATCC

(∼4 folds) in L. donovani infected peritoneal macrophages. Comp.35 had also increased the IL-12 (∼6 folds) and decreased the IL-10 (∼3 folds) mRNA expression and release in vitro. Results of in vivo studies revealed that comp.35 treatment at 25 mg/kg body weight efficiently cleared the hepatic and splenic parasite burden with enhanced Th1response in L. donovani infected BALB/cmice. Hence, this study

A group of 4-allyl-2-methoxyphenol (eugenol) esters were designed, synthesized, and evaluated as potential inhibitors of soybean 15-lipoxygenase (SLO). Compounds 4c, 4d 4f, 4p, and 4q showed the best IC50 in SLO inhibition (IC50 = 1.7, 2.3, 2.1, 2.2, and 0.017 mu M respectively). All compounds were docked into SLO active site and showed that ally) group of compounds is oriented toward the iron atom in the active site of SLO. It is assumed that lipophilic interaction of ligand-enzyme would be in charge of inhibiting the enzyme activity. The selectivity of eugenol derivatives in inhibiting 15-HLOb was also compared with 15-HLOa by molecular modeling and multiple alignment techniques. (C) 2007 Elsevier Ltd. All rights reserved.
