Stereochemistry of Pyrethrosin, Cyclopyrethrosin Acetate and Isocyclopyrethrosin Acetate

study the effects of low level laser diode on no production and healing of diabetic and cortisone acetate and normal wounded sd rats

nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...

7-Enriched Nucleoside Triphosphates. Stereochemistry of Acetate Activation by Acetyl Coenzyme A Synthetase?

Adenosine 5’-( thiophosphate) (AMPS) contains a prochiral phosphorus center. Differentiation of the two diastereotopic oxygens would allow elucidation of the stereochemical course of biological adenylyl transfer reactions. A general method was developed to distinguish between the “pro-R’ and “pro-S’ oxygens. When we converted the AMPS to the isomer A of adenosine S-( 1-thiotriphosphate) (ATP&),...

Clostebol acetate

The title compound, C(21)H(29)ClO(3) [systematic name (8R,9S,10R,13S,14S,17S)-4-chloro-3-oxoandrost-4-en-17β-yl acetate], is a 4-chloro derivative of testosterone, used as an anabolic androgenic agent or applied topically in ophthalmological and dermatological treatments. The absolute configurations at positions 8, 9, 10, 13, 14 and 17 were established by refinement of the Flack parameter as R,...

Vinyl Acetate

Isobaric vapor-Liquid Equilibrium of Ethyl-Acetate+ 2-Propanol and Ethyl Acetate+ Ethanol Mixtures at 84.8 kPa

Accurate vapor-liquid equilibrium data have been obtained for ethyl acetate + 2-propanol and ethyl acetate + ethanol mixtures at 84.8 kPa, and the results are discussed thermodynamically. The vapor-liquid equilibrium data are correlated with redlich-Kister, Margules, Van-Laar and Ortega, equations the parameters and standard deviation of which are calculated and reported. The best correlati...
