چکیده

there are many effective chemothereutic agents used in influenza disease which some of them inhibit virus replication by interfering with fluv (influenza virus) viral binding or its penetration into cell membrane. a series of polyoxometalates compounds such as pom-523 and pm-504 have been synthesized and have showed inhibitory effects on viruses. in this study we examined anti influenza activity of a novel polyoxometalate derivative (pom-4960) synthesized in the faculty of chemistry of damghan university of basic sciences.to evaluate the anti-influenza activity of pom, following the treatment of fluv with pom at different temperatures and incubation periods, viral titer reduction was assessed by haemaglutination assay (ha). the 3-(4,5- dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (mtt) assay was used to determine tcid50 (tissue culture infective dose) of virus, cc50 (median cytotoxic concentration) of pom, protection percentage and antiviral activity of pom in cell culture. rt-pcr and direct immunofluorescent assays were performed to evaluate the effect of pom on viral infection and viral rna load, respectively. pom reduced ha titer near to zero in all cell culture specimens and showed high protection against viral infection of the cells. reduction in viral infection was confirmed by rt-pcr and immunofluorescent staining methods. moreover, this pom derivative has a dual (cumulative) effect on attachment and penetration inhibition compared to other pom’s with just one inhibitory effect. pom-4960 could be considered as a powerful anti-influenza agent with low toxicity and high antiviral potency.

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...

A Novel Heterogalactan from Antrodia camphorata and Anti-Angiogenic Activity of Its Sulfated Derivative

A heterogalactan, named ACW0, was extracted from Antrodia camphorata and purified by anion exchange and gel permeation chromatography. It was composed of galactose (94.98%), traces of mannose (2.41%), and fucose (2.61%), with its molecular weight estimated to be 13.5 k Da. The polysaccharide ACW0 was shown to be a mannofucogalactan with a backbone chain of α-D-1,6-linked Gal, attached by a non-...
