[ 1 ] - Novel Oxadiazole Thioglycosides as Potential Anti- Acinetobacter Agents
The glycosylation of 1,3,4-oxadiazole-2-thiones has been performed with peracetylated β-pyranosyl bromide in the presence of potassium carbonate. Deprotection of acetylated thioglycosides was necessary for increasing their antibacterial effects. The structure of nucleosides were confirmed by 1H NMR, 13C NMR and HRMS. The anomeric protons of nucleosides c1–4 were assigned to the doublet, confirm...
[ 2 ] - Calixtyrosol: a Novel Calixarene Based Potent Radical Scavenger
The oxidative stress causes many diseases in human, therefore antioxidants have a specialposition in the medicinal chemistry. Tyrosol is an important antioxidant with a plenty ofbiological properties. There are many strategies such as clustering single drug units in orderto develop new drugs. The cluster effect can increase drug effects relative to single drug unit.Calixtyrosol is the novel clu...
[ 3 ] - Synthesis and Antibacterial Evaluation of New Thione Substituted 1,2,4-Triazole Schiff Bases as Novel Antimicrobial Agents
The condensation reaction of 5-(4-aminophenyl)-4-phenyl-1,2,4-triazole-3-thione with salicylaldehyde, 4-hydroxybenzaldehyde, 5-chlorosalicylaldehyde, 5-bromosalicylaldehyde, 2-nitrobenzaldehyde, 3-nitrobenzaldehyde, 4-nitrobenzaldehyde and 4-methoxybenzaldehyde in methanol results in series of new Schiff bases. The structure of Schiff bases were confirmed by 1H NMR, 13C NMR, IR and mass spectro...

[ 7 ] - Calixapap: Calixarene-based Cluster of Acetaminophen as a Novel Antiradical Agent
In this paper, the synthesis and free-radical scavenging capacity of novel calix[4]arene-based cluster of paracetamol was reported. The phenolic structures of acetaminophen and calix[4]arene prompted us for designing a synthetic route for calix[4]arene-based cyclic tetramer of paracetamol. The present chalice-shaped cluster is the first example of calixarene/acetaminophen hybrid and paracetamol...
