Chemical Screening, Antioxidant Potential and Antiangiogenic Effect of Microporus Xanthopus (fr.) Kuntze, Ganoderma Orbiforme (fr.) Ryvarden and Polyporus Fasciculatus (pat) lloyd, Medicinal Mushrooms from Gabon

Therapeutic potential of Ganoderma lucidum (Fr.)

Mushrooms represent a major and untapped source of potent new pharmaceutical products. The antioxidant, antiinflammatory, antinociceptive, antimutagenic, anticarcinogenic, antitumour, hepatoprotective, nephroprotective and cardioprotective activities of the methanolic extract of Ganoderma lucidum (Fr.) P. Karst. collected from tropical South India were evaluated for the revalidation of its util...

Comparison between antioxidant activity and bioactive compounds of Ganoderma applanatum (Pers.) Pat. and Ganoderma lucidum (Curt.) P. Karst from Iran

Members of Ganoderma genus, belong to Basidiomycota, such as Ganoderma applanatum and Ganoderma lucidum have been noticed in traditional and modern medicine and pharmacology for their medicinal properties and bioactive compounds. The present study is undertaken to determine whether there is difference between chemical properties of G. applanatum and G. lucidum. The fresh mature fruiting bodies ...

extraction and acetylation of purified trypsin from bovin pancreas and study of some its physico-chemical properties

آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...

FR-900520 and FR-900523, novel immunosuppressants isolated from a Streptomyces. II. Fermentation, isolation and physico-chemical and biological characteristics.

FR-900520 and FR-900523, novel neutral macrolide immunosuppressants, were isolated from the cultured broth of Streptomyces hygroscopicus subsp. yakushimaensis No. 7238. Their molecular formulae were determined as C43H69NO12 and C42H67NO12, respectively. The compounds suppressed immune response in vitro. IC50 values of FR-900520 and FR-900523 for mouse mixed lymphocyte reaction were 0.55 nM and ...
