The solubility enhancement of poorly soluble compounds is an important task in pharmaceutical technology as it leads to better bioavailability and a more efficient application. Fused dispersions (FDs) of simvastatin (SIM) using PEO-PPO block copolymer were prepared which paved the way for the formation of an amorphous product with enhanced dissolution and bioavailability. The accumulative s...

Precipitons are molecular phase tags for chemical separations. They can be switched from a high-solubility to a low-solubility state to facilitate product, reagent, or catalyst isolation. This paper presents the first photoactivated precipiton and demonstrates that this precipiton is an efficient amine scavenging agent in solution-phase syntheses of amides, ureas, and imines. This approach to a...

Reading frame selection of nucleic acids has important implications for protein engineering and genomics. Current methods are limited because selection of the gene of interest inevitably depends on the solubility of its translated product. Here we report the construction of the pInSALect vector, which provides strict reading frame selection without concomitant selection for protein solubility o...

[1] Fish have been shown to produce high (10 to 48 mol %) magnesium calcite as part of the physiological mechanisms responsible for maintaining salt and water balance. The importance of this source to the marine carbon cycle is only now being considered. In this paper, we report the first measurements of the solubility of this CaCO3 in seawater. The resulting solubility (pK*sp = 5.89 0.09) is a...

Protein-fusion constructs have been used with great success for enhancing expression of soluble recombinant protein and as tags for affinity purification. Unfortunately the most popular tags, such as GST and MBP, are large, which hinders direct NMR studies of the fusion proteins. Cleavage of the fusion proteins often re-introduces problems with solubility and stability. Here we describe the use...

Poor solubility of active pharmaceutical ingredients (APIs) is a great challenge for the pharmaceutical industry and, hence, drug nanocrystals are widely studied as one solution to overcome these solubility problems. Drug nanocrystals have comparatively simple structures which make them attractive for the formulation for poorly soluble drugs, and their capability to improve the dissolution in v...

Date syrup powder is a new product which can be used as sugar substitute. First, the date syrupwas spread out on a foil and placed in the oven at 60°C for 24 hours. Date syrup was separated from the foil andgrinded. 2% agar and 2% starch were added and syrup with agar and starch that was in a lumpy shape werecrushed and spread on the foil and placed at 60°C for 24 hours. Powdered granules, agar...

Aim: 1) To increase water solubility of indomethacin drug using mixed solvency approach. 2) To employ use of non toxic solubilizers for increasing solubility of a poorly water soluble drug. Study Design: Trial and error based experimental study. Place and Duration of Study: School of Pharmacy, Devi Ahilya Vishwavidyalaya, UTD, Takshashila Campus, Indore, India and College of Pharmacy, IPS Acade...

Modified starch is synthesized to change the physical and chemical properties, one of which solubility. Two new things were produced in substitution process, namely modifications final stage (workup) reaction each substituent, changes neutralization stage/carboxymethyl solids using 30% CH3COOH use methanol pro-analyst sulfonate deposition process. The results solubility test showed that at room...
