The Aplysiatoxins: Reactions with Acid and Oxidants
Under the influence of ethanolic acetic acid the aplysiatoxins rearrange with retention of all carbon atoms. An osmate of the anhydrotoxins can be rediced to a glycol which resists oxidative cleavage but loses water and rearranges with acid. Consideration of PMR and reactivity datalead to partialassignment of relative stereochemistry of
متن کاملThe Aplysiatoxins
From the marine gastropod molluse Stylocheilus longicauda we isolated aplysiatoxin and debromoaplysiatoxin (LD100, 0.3 mg/kg) and equal amounts of their non-toxic acetates. The structures of these compounds were deduced by spectral studies and by reductive and hydrolytic degradation. iNTRODUCTION The attention of many natural product chemists was directed towards marine-oriented research at the...

study of dna interaction with ethylenediaminetetraacetic acid and sesamol food additives
برهمکنش dnaتیموس گاوی طبیعی (ct-dna) با اتیلن دی آمین تترااستات (edta)در بافرtris-hcl با 8/7 ph ( دراین ph،edta به نمک دی سدیم تبدیل می شود) وسسامول در بافر tris-hcl با4/7 ph مورد بررسی قرار گرفته است. edta و سسامول استفاده فراوانی در تکنولوژی غذایی و صنعت شیمیایی دارند. مدل اتصال dna مربوط بهedta بوسیله اسپکتروفتومتری جذب، دورنگ نمایی حلقوی(cd)، ویسکومتری وژل الکتروفورز بررسی شده است. طیفuv ...
15 صفحه اولthe evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology
abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
