[SnPh3(DMNI)] (1), (2,6-dimethoxynicotinic acid (DMNIH)) was prepared by the reaction of SnPh3Cl with DMNIH. Molecular structure of 1 was determined by X-ray diffraction studies. The cytotoxic activity of 1 was tested against tumour cell lines human cervical adenocarcinoma HeLa, human myelogenous leukemia K562, human malignant melanoma Fem-x and normal immunocompetent cells, non-stimulated peripher Read More

Novel succinimide derivatives based on nimesulide were designed as potential anticancer agents and their synthesis was carried out using a straightforward and atom economic method. The key step of this methodology involved an Aza-Michael addition of several nitrogen nucleophiles to the corresponding N-aryl maleimide derivatives prepared efficiently from nimesulide via a two-step process. A number of compounds co Read More

Glycosylation has been widely used to improve the efficacy and bioavailability of certain anticancer drugs. In the present work, artemisinin glucoside was synthesized through glycosylation, and its antimuor effect was investigated both in vivo and in vitro by detecting its effects on suppressing U14 xenograft tumor proliferation, on inducing Hela cell apoptosis, and on affecting p53, Bcl-2 and Bax expressions. In vivo, Read More

Non-steroidal anti-inflammatory drugs (NSAIDs) are evolving as the prototypical chemopreventive agents against colon cancer, an opinion nowadays reinforced by a substantial form of epidemiological, animal, and basic science data. Apart from their preventive role in the prophylaxis and management of colon cancer, NSAIDs at lower doses are widely employed in permutation with conventional anticancer drugs in ord Read More

Type II diabetes Mellitus is one of the common diseases worldwide and often recognized as life style disease. The major symptom of this disease is an increase in blood glucose level resulting in polydypsia, polyuria and polyphagia. Molecular modeling was used to design the drug molecules. Docking results showed imidazolidine derivatives have good interaction with the DPP IV receptors. The compound IMA4 showed good ori Read More

2-Chloro-1,3-dioxo-2,3-dihydro-1H-inden-2-yl acetate (1) and N11,N11'-benzene-1“,2”-diamino-11H,11'H- [11,11'-biindeno[1,2-b]quinoxaline] (2) were synthesized and structures have been established on the basis of spectral analysis. The structure of (2) has also been confirmed by single crystal X-ray analysis. Both the synthesized compounds were screened for their anticancer, antimicrobial and cholinesterase enzymes in Read More

Four Caudatin glycosides were synthesized from Caudatin by reaction with tetra-O-actyl-D-glycosyl bromide catalyzed by CdCO3 and tested in vitro for their antiproliferative activities against human lung cancer A549, human prostate cancer PC3, human liver cancer BEL-7402 and human gastric cancer SGC-7901 cells. The IC50 values indicated that the inhibitory effect of Caudatin-tetra-O-actyl-D-glycosides was superior or compa Read More

Nineteen novel 4-indolyl-5-phenyl(indolyl)-1,2-dihydropyrazol-3-ones were synthesized and evaluated for their GSK-3β inhibitory activity. Half of the tested compounds showed moderate GSK-3β inhibitory activity. Preliminary structure-activity relationships were discussed, which showed that the presence of 3,4,5-trimethoxy group on the benezene ring enhanced potency while the existence of an electron-withdrawing group at th Read More

Solid state structure information for (2E)-1-(5-bromothiophen-2-yl)-3-[4-(dimethylamino)phenyl]prop-2-en-1- one is revealed by using single crystal X-ray diffraction study. The conformation of the molecule in solid state is used to carry out the drug design studies like structure optimization by Density Functional Theory (DFT) and Induced Fit Docking (IFD) study on human aldose reductase. The asymmetric unit of (2E)-1-(5-brom Read More

A series of 3-substituted-thiochroman-4-one semicarbazone derivatives were designed based on the bioisosterism and combination principle in drug design. The target compounds were prepared from 3-substitutedthiochroman- 4-one (1) and 4-substituted-semicarbazides( 2), their structures were confirmed by MS and 1H NMR. The antifungal assay was carried out in vitro by twofold dilution. The result shows that all the compo Read More

Diverse polyfunctionalized tetrahydroquinolines, easily prepared using BF3 .OEt2-catalyzed three component imino Diels-Alder reaction, were tested in vitro against Trypanosoma cruzi and Leishmania chagasi parasites and also for cytotoxicity using Vero and THP-1 mammalian cell lines. These studies showed that the most active compound was 7h (IC50 5.77 ± 0.21; IC90 40.43 ± 1.58 μM for T. cruzi and IC50 0.27 ± 0.03; Read More

Recombinant HSV-2 glycoprotein B amino-proximal polypeptide, a new designed polypeptide with potential immunogenic effect in vivo, was engineered. It is composed of thioredoxin and HSV-2 glycoprotein B amino-proximal segment. The recombinant gene was then highly expressed in Escherichia coli. Furthermore, the expressed fusion protein could effectively prevent degradation of polypeptide, and purified fusion prot Read More
