[ 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...

[ 9 ] - Calixmexitil: Calixarene-based Cluster of Mexiletine with Amplified Anti-myotonic Activity as A Novel Use-dependent Sodium Channel Blocker

Mexiletine as the first choice drug in myotonia treatment is a chiral sodium channel blocker clinically used in its racemic form. The phenolic structure of this drug, prompted us to design its novel calix[4]arene-based cluster in a chalice-shaped structure. Therefore, the present study reports the synthesis and in-vitro anti-myotonic activity of the chalice-shaped cluster of mexiletine...

[ 11 ] - Calixarbutin: A Novel Calixarene-based Potential Water-soluble Anti-tyrosinase Agent with High Anti-melanoma Activity

Since melanocytes are the origin of melanoma and some skin disorders such as melasma, they are important cells from the perspective of medicinal chemistry. Therefore, a medication that can simultaneously overcome these diseases will be a successful potential therapeutic agent. Arbutin with phenolic structure is a powerful natural anti-tyrosinase agent. Hence, the phenolic structure of this drug...
