Epiandrosterone

Product name:Epiandrosterone
CAS: 481-29-8
Molecular Formula:     C19H30O2
Formula Weight:290.44
Description:
       Epiandrosterone is a steroid hormone with weak androgenic activity. It is a natural metabolite of dehydroepiandrosterone via the 5-alpha reductase enzyme. 
      Epiandrosterone has been shown to naturally occur in most mammals including pigs.
      Epiandrosterone is naturally produced by the enzyme 5-alpha reductase from the adrenal hormone dehydroepiandrosterone (DHEA).Epiandrosterone can also be converted from the natural steroids androstanediol via 17β-hydroxysteroid dehydrogenase or from androstanedione via 3β-hydroxysteroid dehydrogenase.

What is SelectFluoro

Replacement of hydrogen atoms by fluorine substituents into organic substrates is of great interest in synthetic chemistry due to the high electronegativity of fluorine and relatively small steric hindrance fluorine atoms. Many nucleophilic fluorine sources are available for the derivatization of organic molecules under acidic conditions, basic and neutral. However, electrophilic fluorination historically required molecular fluorine, whose notorious toxicity and explosive tendencies limit its application in research. The need for an electrophilic fluorination reagent, secure, stable, highly responsive and accessible to industrial production as an alternative, it is very hazardous molecular fluorine was the inspiration for the discovery of Select. This reagent is not only an electrophilic fluorination of available reagent, but it is also safe, non-toxic and easy to handle. In this article, we describe the many applications Select and discuss possible ways for its reaction.

9-bromo-1-nonanol

9-bromo-5-morpholino-tetrazole [1,5-c] quinoline cytotoxicity (BMT) is applied to the cell line L1210 murine leukemia and carcinoma cells of the Caco-2 colon. We have the two highest concentrations of BMTQ (149.2 and 74.6 microM) induces an acute cytotoxic effect, but other concentrations tested (<74.6 microM) exhibits a / dependent cytotoxic effect depending on the time and / concentration. The sensitivity of mouse leukemia L1210 cells and carcinoma cells of the Caco-2 colon was expressed in the same order. Cytotoxicity BMTQ not bound by changes in the cell cycle profile. After the effects of cytotoxicity associated BMTQ we observed induction of ssDNA breaks after BMTQ treatment. All BMTQ concentrations increases the level of ssDNA breeze 1.3-2.9 times (after 2 hours of treatment) and 1.6-2.8 times (after 4 hours of treatment) in Caco-2 cells compared to control. No apoptotic DNA fragmentation was induced by BMTQ in Caco-2 cells is recorded.
