Biotransformation of biphenyl by Paecilomyces lilacinus and characterization of ring cleavage products.
We examined the pathway by which the fungicide biphenyl is metabolized in the imperfect fungus Paecilomyces lilacinus. The initial oxidation yielded the three monohydroxylated biphenyls. Further hydroxylation occurred on the first and the second aromatic ring systems, resulting in the formation of five di- and trihydroxylated metabolites. The fungus could cleave the aromatic structures, resulti...
متن کاملNovel ring cleavage products in the biotransformation of biphenyl by the yeast Trichosporon mucoides.
The yeast Trichosporon mucoides, grown on either glucose or phenol, was able to transform biphenyl into a variety of mono-, di-, and trihydroxylated derivatives hydroxylated on one or both aromatic rings. While some of these products accumulated in the supernatant as dead end products, the ortho-substituted dihydroxylated biphenyls were substrates for further oxidation and ring fission. These r...

ماکروسیکلهای شیف باز از اهمیت زیادی در شیمی آلی و دارویی برخوردار می باشند. این ماکروسیکلها با دارابودن گروه های مناسب در مکانهای مناسب می توانند فلزاتی مثل مس، نیکل و ... را در حفره های خود به دام انداخته، کمپلکسهای پایدار تولید نمایند. در این پایان نامه ابتدا یک دی آلدئید آروماتیک از گلیسیرین تهیه می شود و در مرحله بعدی واکنش با دی آمینهای آروماتیک و یا آلیفاتیک در رقتهای بسیار زیاد منجر به ت...

Paecilomyces lilacinus, an environmental mold found in soil and vegetation, rarely causes human infection. We report the first case of P. lilacinus isolated from a vaginal culture in a patient with vaginitis.
متن کاملSuccessful Treatment of Paecilomyces lilacinus Onychomycosis with Efinaconazole and Tavaborole.
Paecilomyces lilacinus, also known as Purpureocillium lilacinum, is a non-dermatophyte mold found in the soil and used as nematocide for crops. P. lilacinus can cause rare opportunistic infections in humans ranging from endocarditis, keratitis, to onychomycosis with significant resistance to conventional antifungals. There are only two cases of onychomycosis caused by P. lilacinus reported in t...
