Antioxidants have been shown to be effective in murine models of sepsis. Protocatechuic acid has antioxidant activity. In the present study, the protective effects of protocatechuic acid and its derivatives were investigated in a mouse model of septic shock induced by lipopolysaccharide (LPS)/D-galactosamine (GalN). Pretreatment of animals with protocatechuic acid effectively suppressed LPS/Gal...

Racemic [(±)-4-isopropyl-1-methyl-7-oxa-cis-bicyclo[4.3.0]non-4-en-8-one] and optically active δ,ε-unsaturated lactones [(-)-(1R,6R)-4-isopropyl-1-methyl-7-oxabicyclo[4.3.0]non-4-en-8-one and (+)-(1S,6S)-4-isopropyl-1-methyl-7-oxabicyclo[4.3.0] non-4-en-8-one)] with the p-menthane system were obtained and their odoriferous properties were evaluated. Biotransformations of the racemic lactone wit...

Despite a number of studies on the efficacies of antiseptics for the prevention of blood culture contamination, it still remains unclear which antiseptic should be used. Although the combination of povidone-iodine and isopropyl alcohol has been traditionally used in many institutions, the application of povidone-iodine needs extra time, and there is little evidence that this combination could h...

Ondansetron HCl delivery through oral route suffers due to its low bioavailability due to first-pass metabolism. Therefore, the microemulsion-based transdermal delivery may be a better substitute for it. The pseudoternary phase diagrams were constructed to determine compositions of microemulsions, and ondansetron HCl microemulsions for transdermal delivery were developed using isopropyl myrista...

CTP : phosphocholine cytidylyltransferase activity exists in both the microsome and cytosol fractions of adult lung, 36 and 59%, respectively. Although these enzyme activities are stimulated in vitro by added lipid activators (i.e. phosphatidylglycerol), there are significant levels of activity in the absence of added lipid. We have removed endogenous lipid material from microsome and cytosol p...

Isopropyl myristate finds many applications in food, cosmetic and pharmaceutical industries as an emollient, thickening agent, or lubricant. Using a homogeneous reaction phase, non-specific lipase derived from Candida antartica, marketed as Novozym 435, was determined to be most suitable for the enzymatic synthesis of isopropyl myristate. The high molar ratio of alcohol to acid creates novel si...

Methyl indolenines (4a-c) and(5a-c) were prepared in high yield by a Fischer indole synthesis reaction of o,m-tolylhydrazine hydrochlorides (1a-b) with isopropyl methyl ketone (2) and 2-methylcyclohexanone (3) in acetic acid at room temperature. o,p- Nitrophenylhydrazines (1c-d) were reacted with 2-methylcyclohexanone (3) in acetic acid at reflux to give nitroindolenines (5d-e), while the attem...

The reaction o f 5'-CMP with methyl, ethyl, «-propyl and isopropyl iodides gave predomi­ nantly ribose alkylated products. Various alkylated derivatives have been characterized using UV spectroscopy, paper electrophoresis, 'H N M R and FAB (negative) mass spectroscopic techniques. Under strongly alkaline conditions the 2'-0-alkylated derivatives are synthesized in maximal yields. Isopropylation...

       Volatile constituents of the seed kernel and leaf of cultivated Moringa peregrina (Forssk.) Fiori, Agricolt collected after hydrolysis were analyzed by GC and GC/MS. Five glucosinolate degradation products which constituted almost the whole isolated oil of the seed kernel were identified to be: isobutyl isothiocyanate (94.0%), isopropyl isothiocyanate (4.9%), sec-butyl isothiocy...
