A series of novel N-(furan-2-yl)-1-(5-substituted) phenyl-1,3,4-oxadiazol-2-yl) methanimines (Fa-e) were synthesized and evaluated for antitubercular activity against Mycobacterium tuberculosis (H37Rv) strain by using alamar blue assay. The synthesized compounds were characterized based on IR, (1)HMR and mass spectral analysis. The toxicity profile was predicted by organic chemistry portal, a w...

Stabilized magnetic nanoparticles are the subject of intense research for targeting applications and this work deals with the design, preparation and application of specific core-shell nanoparticles based on ionic crosslinked chitosan. The nanometric size of the materials was demonstrated by dynamic light scattering (DLS) and field emission scanning electron microscopy (FESEM) that also proved ...

A series of 3-arylidene-5-(substituted phenyl)-2(3H)-furanones (3-10) and their nitrogen analogues, 3-arylidene-5-(substituted phenyl)-1-benzyl-2(3H)-pyrrolone (11-14), and 3-arylidene-5-(substituted phenyl)-2(3H)-pyrrolones (15-21) were synthesized. All the compounds were screened for their antimycobacterial activity in vitro against Mycobacterium tuberculosis H37Rv (ATCC 27294) in BACTEC medi...

A multicenter study was conducted to expand the generation and analysis of data that supports the proposal of a reference method for the antifungal susceptibility testing of filamentous fungi. Broth microdilution MICs of amphotericin B and itraconazole were determined in 11 centers against 30 coded duplicate pairs of Aspergillus spp., Fusarium spp., Pseudallescheria boydii, and Rhizopus arrhizu...

The effects of fucose-containing sulfated polysaccharides, ascophyllan and fucoidan, isolated from the brown alga Ascophyllum nodosum, on the growth of various cell lines (MDCK, Vero, PtK 1 , CHO, HeLa, and XC) were investigated. In a colony formation assay, ascophyllan and fucoidan showed potent cytotoxic effects on Vero and XC cells, while other cell lines were relatively resistant to these p...

A series of novel substituted N-(3-acetyl-2-oxoquinolin-1(2H)-yl)benzamide (AJQC1AJQC12) have been synthesized upon refluxing 3-acetyl-1-amino-quinolin-2-one and substituted benzoic acid in the presence of dry redistilled pyridine and silicon tetrachloride as coupling agent. 3-acetyl-1-amino-quinolin-2-one (AJQ1-AJQ12) were synthesized from substituted 3-acetyl coumarin upon refluxing with hydr...

BACKGROUND Cyclooxygenase (COX)-2 is overexpressed in several tumor entities and seems to play a key role in carcinogenesis. This makes it a potential target in cancer therapy. MATERIALS AND METHODS Twelve phosphorothioate-modified antisense oligonucleotides (asODNs) against six targets of COX-2 mRNA were transfected to A-549 lung carcinoma cells. COX-2 mRNA and protein levels were determined...

Resazurin (or Alamar Blue) is a poorly fluorescent dye. During the cellular reduction of resazurin, its highly fluorescent product resorufin is formed. Resazurin assay is a commonly applied method to investigate viability of bacterial and mammalian cells. In this study, the interaction of resazurin and resorufin with β-cyclodextrins was investigated employing spectroscopic and molecular modelin...

Loperamide is a peripheral opiate agonist that can cause apoptosis and G2/M arrest in human cancer cell lines and may sensitize cells to chemotherapy. The objectives of this study were to investigate the effects of loperamide on viability, apoptosis and cell cycle kinetics in canine cancer cells and to establish whether the drug sensitizes cells to doxorubicin. Cell viability was assessed using...

Mycophenolic acid (MPA) is the active metabolite of mycophenolate mofetil. This study designed to investigate the mechanism of cytotoxicity of MPA on the genetically engineered PC12 Tet Off (PTO) neuronal cells with p53 gene. Alamar Blue (AB) reduction showed concentration-dependent cytotoxicity of MPA on PTO cells with IC50 value of 32.32 ± 4.61 mM. The reactive oxygen species (ROS) generation...
