An adjuvant composition containing a) one or more alkyl glucamides of the formula (I), wherein R1 represents a linear or branched alkyl group having 5 to 9 carbon atoms, R2 represents an alkyl group having 1 to 3 carbon atoms; b) at least one water-soluble ammonium salt, preferably selected from the group consisting of ammonium sulfate, ammonium nitrate, ammonium nitrate urea, ammonium phosphat...

Experimental solubilities of four antiepileptic drugs, that is, lamotrigine, diazepam, clonazepam, and phenobarbital in propylene glycol + water mixtures at 298.15 K were reported. The solubility of drugs was increased with the addition of propylene glycol, and the maximum values are observed in neat propylene glycol. The Jouyban-Acree model was used to fit the experimental data, and the solubi...

Venlafaxine representing a new class of antidepressants is a potent serotonin/ norepinephrine reuptake inhibitor. Transdermal delivery of venlafaxine hydrochloride (VHCl) may result in proper patient compliance by reducing the incidence of the undesirable GI problems generally associated with its plural oral dosing. The present study is an attempt to investigate the improvement of the transderm...

Now a day transdermal drug deliveries are increasing rapidly for the treatment of various diseases so the present study was conducted on different penetration enhancers for permeation of antidiabetic drug, glipizide (sulfonyl urea derivative) through skin. Different types of penetration enhancers such as terpenes and terpenoids, pyrrolidones, oxazolidinones, fatty acids etc are used for permeat...

Gaston, Lamont W. (National Heart Institute, National Institutes of Health, Bethesda, Md.) and E. R. Stadtman. Fermentation of ethylene glycol by Clostridium glycolicum, sp. n. J. Bacteriol. 85:356-362. 1963.-An anaerobic organism which utilizes ethylene glycol as a source of energy and carbon has been isolated from mud. It is a long (5 mu), slender, motile, gram-positive, spore-forming rod, wi...

Propylene glycol (PG) is a solvent commonly used in medications that, while benign at low doses, may cause toxicity in adults and children at high doses. We describe a case and the physiologic sequelae of propylene glycol toxicity manifested in a critically ill adolescent male with refractory myoclonic status epilepticus aggressively treated with multiple PG-containing medications (lorazepam, p...

Propylene glycol and triacetin are chemical compounds, commonly used as food additives. Though the usage of the pure chemicals is not considered harmful when used as dietary supplements, little is known about the nature of their thermal degradation products and the impact they may have on human health. For these reasons, in this manuscript we investigate the thermal decomposition mechanisms of ...

BACKGROUND Compounds present in green tea have proved to inhibit the growth and activity of bacteria associated with infections. OBJECTIVES To assess the effects of green tea leaves extract in presence of propylene glycol on the aerobic mouth bacteria load. MATERIALS AND METHODS Saliva of 25 volunteer girl students aging 20-25 years were selected and evaluated by a mouthwash sample containi...

The process of molecular recognition is the assembly of two or more molecules through weak interactions. Information in the process of molecular recognition can be transmitted to us via physical signals, which may find applications in sensing and switching. The conventional signals are mainly limited to light signal. Here, we describe the recognition of diols with Cu(1,10-phenlothroline)2SeO4 a...

High throughput methodologies screened 81 different metal salts and metal salt combinations as catalysts for the carboxylation of propylene glycol to propylene carbonate, as compared to a 5 mol% Zn(OAc)2/p-chlorobenzene sulfonic acid benchmark catalyst. The reactions were run with added acetonitrile (MeCN) as a chemical water trap. Two new catalysts were thereby discovered, zinc trifluoromethan...
