Decolorization of six synthetic dyes using three sources of fungal laccase with the origin of Aspergillus oryzae, Trametes versicolor, and Paraconiothyrium variabile was investigated. Among them, the enzyme from P. variabile was the most efficient which decolorized bromophenol blue (100%), commassie brilliant blue (91%), panseu-S (56%), Rimazol brilliant(More)
Four commonly used spices plants in Iran were evaluated for cytotoxicity effect using Brine Shrimp Lethality (BSL) assay. Essential oils and various extracts of Heracleum persicum, Nigella arvensis, Cinnamomum zeylanicum and Zingiber officinale were assessed by two methods of disk and solution of BSL. Data were processed in probit-analysis program to(More)
During screening for antibiotic producing microorganisms from environmental soil samples, the supernatant of a bacterial isolate was found to have antibacterial and antifungal activity on the standard indicator species. The standard cylinder-plate method was used to determine the inhibitory effect of the crude supernatant of each isolate on 6 bacterial and(More)
The present study was planned to design some novel aldimine-type Schiff bases bearing 3,4,5-trimethoxyphenyl and 1,2,4-triazole-3-thione/thiol as potential tubulin polymerization inhibitors. The obtained results of the molecular docking study using the tubulin complex (PDB code: 1SA0) showed that compounds H-25 and H-26 were well fitted in the colchicine(More)
BACKGROUND Enzymatic elimination of synthetic dyes, one of the most environmentally hazardous chemicals, has gained a great interest during the two last decades. The present study was performed to evaluate the decolorization and detoxification potential of the purified laccase of Paraconiothyrium variabile in both non-assisted and hydroxybenzotriazole-aided(More)
BACKGROUND In recent years, enzymatic-assisted removal of hazardous dyes has been considered as an alternative and eco-friendly method compared to those of physicochemical techniques. The present study was designed in order to obtain the optimal condition for laccase-mediated (purified from the ascomycete Paraconiothyrium variabile) decolorization of Acid(More)
Blood coagulation plays a critical role not only in hemostasis but also in many physiological and pathological conditions. Epidemiological studies have shown that blood coagulation capacity in humans increases with age. Towards understanding the underlying mechanisms, the age regulation of factor IX, a key blood coagulation factor, was extensively studied.(More)
In the present study, Fe3 O4 magnetic nanoparticles were synthesized by the coprecipitation of Fe(2+) and Fe(3+) ions and used as a nanocarrier for the production of piroctone-olamine-loaded Fe3 O4 nanoparticles (Fe3 O4 @PO NPs). The nanocrystalline structure of the prepared iron oxide species was confirmed by the X-ray diffraction spectroscopy method.(More)
A series of tacrine-based pyrazolo[4',3':5,6]pyrano[2,3-b]quinolines and related compounds were designed and synthesized for targeting AChE, BuChE and 15-LOX enzymes in the field of Alzheimer's disease therapy. Most of compounds showed potent activity against cholinesterases and mild potency toward 15-LOX enzyme. In particular, compounds 29, 32 and 40(More)
A series of hybrid Aldimine-type Schiff base derivatives including trimethoxyphenyl ring and 1,2,4-triazle-3-thiol/thione were designed as tubulin inhibitors. The molecular docking simulations on tubulin complex (PDB: 1SA0) revealed that derivatives with nitro and /or chloro or dimethylamine substitutes (4-Nitro, 2-Nitro, 3-Nitro, 4-Cl-3-nitro, and 4-N(CH3(More)
