The effects of extrusion conditions on cooking degree, flour dispersion viscosity and mineral potential availability of extruded bean flour were studied. Phaseolus vulgaris beans of the agronomic cultivar "Flor de mayo" were ground and dehulled to obtain grits and then extruded at different temperatures (140, 160 and 180 degrees C) and moisture contents (17, 20 and 23%), according to a bifactor...

Different nitronaphthylbutadienes have been previously proved to have antitumour activity. The main drawback of these derivatives is their low water solubility. With the aim of facilitating the administration of these new drugs we have synthesized the hexyl (2Z,4E)-2-methylsulfanyl-5-(1-naphthyl)-4-nitro-2,4-pentadienoate analogue (1-Naph-NHCB) which is demonstrated to be easily included into c...

Background and objectives: Essential oils are used for their flavors and fragrances and their medicinal properties in food, cosmetic, agriculture and pharmaceutical industries. This study was focused on the selection of the best solvent(s) which would increase water solubility of ketone and phenol classes of essential oils. Methods: The solubility of s...

Aceclofenac is a non-steroidal anti-inflammatory drug (NSAID) that exhibits analgesic, antipyretic and anti-inflammatory activities. It is practically insoluble in water. The effect of hydrotropes such as urea and sodium citrate and blends (urea + sodium citrate) on the solubility of aceclofenac was investigated. The enhancement in the solubility of aceclofenac was more than 5 and 25 folds in 3...

Complexing a drug may alter the rate and extent of drug absorption. The complex formation is very well applied in the administration of poorly water-soluble drugs. The drugs selected for the study are cyclooxygenase-2 inhibitors, are potent anti-infl ammatory drugs with very low water solubility. The water solubility of these drugs was enhanced by complexing with β-cyclodextrin. In vitro absorp...

diosmin, a vascular-protecting agent, is practically insoluble in water, and its oral absorption is limited by its extremely low dissolution rate. in this study, β-cyclodextrin (βcd) and 2-hydroxypropyl-β-cyclodextrin (hpβcd) were obtained to improve the solubility and dissolution rate of diosmin. phase solubility studies of diosmin with βcd and hpβcd in distilled water were conducted to charac...

background: the strong link between sealer solubility and periapical reinfection indicates that water solubility of new sealers should be studied. this study aimed to assess the water solubility of five root canal sealers (ah-26, topseal, 2-seal, acroseal, and roeko seal automix [rsa]). materials and methods: in this in vitro experimental study, 30 specimens were fabricated from each of the abo...

       The Extended Hildebrand Solubility Parameter Approach (EHSA) is used to estimate the solubility of satranidazole in binary solvent systems. The solubility of satranidazole in various water-PEG 400 mixtures was analyzed in terms of solute-solvent interactions using a modified version of Hildebrand-Scatchard treatment for regular solutions. The solubility equation employs term interaction ...

Pyrazino[2,1-a]isoquinolin analogues were reported as potent activators of Nrf2/ARE signaling both in vitro and in vivo by our group. In this study, we simplified the ring system to investigate the functions of various parts of the pyrazino[2,1-a]isoquinolin scaffold. We proved that the tetrahydroisoquinoline was not essential for activity and the pyrido[1,2-a]pyrazin analogues 3b and 3g retain...
