(1) Proteins have been partitioned in poly(ethylene glycol) (PEG)-salt systems containing hydrotropes.
(2) Multicellular spheroids from a human neuroblastoma cell line (NB1-G) were used to investigate the effect of etoposide in solution, as its commercial formulation, Vepesid, in the presence of a nonionic surfactant, Brij 30, and a hydrotropic agent, sodium salicylate.
(3) The "blow over" apparatuses Hydrotrop 200, Aquapor and VH 620 (infant) did not cause any germ propagation in the resuscitation tubes, whereas in the "blow through" apparatuses Bennett Cascade and VH 620 (adult) germ propagation is quite considerable.
(4) Additive hydrotropic effects were observed for nicotinamide and urea, which disrupt the water structure, while structure formers such as sorbitol exerted negative effects.
(5) Photon correlation spectroscopy indicated possible unfolding of BSA molecules in solutions of sodium benzoate and sodium salicylate at 25 degrees C. The effect of these hydrotropes on the heat coagulation of BSA was concentration-dependent.
(6) Different hydrotropic substances may show great differences of influence on the micellar weights and the cmc respectively.
(7) In this work, hydrotropic agents such as sodium benzoate, sodium o-hydroxybenzoate (sodium salicylate), sodium 2,5-dihydroxybenzoate (sodium gentisate), and the sodium salts of 2,4-dihydroxy- and 2,6-dihydroxybenzoic acid and of 2,4,6-trihydroxybenzoic acid have been used as alternative solubilizers of etoposide.
(8) Hydrotropes are surface active compounds with strong ionic nature with a smaller hydrophobic part as compared to surfactants.
(9) An attempt has been made to formulate a stable, aqueous injection of nifedipine (1) using the technique of hydrotropic solubilization.
(10) The effect of pH, hydrotrope concentration, polymer molecular weight and protein molecular weight on partitioning of proteins including enzymes and their separation has been investigated.
(11) The probable mechanism involves a complexation type of interaction at a low concentration of hydrotrope, aggregation of the hydrotropic molecules and inclusion of 1 in these aggregates at high concentration; and structural changes in water caused by hydrotropes.
(12) This is substantiated by measuring the concentration of hydrotropes in both the phases.
(13) Higher concentrations of the hydrotropes considerably reduced Tm and inhibited gelation of BSA, the effect of sodium salicylate being more pronounced, as was the lower aggregation rate of BSA.
(14) Preliminary experiments have shown that hydrotropes at low concentrations do not affect enzyme activity and do not have any bactericidal activity.
(15) Relatively low concentrations stabilized the protein structure as indicated by the increase in the transition temperature(Tm) and induced gelation at temperatures and BSA concentrations lower than those required in the absence of hydrotropes.
(16) The effects of hydrotropes may be explained on the basis of interaction of PEG and the hydrotropes.
(17) The effects of hydrotropic substances on the phase solubility relationship of MeT showed that inclusion complex formation with 2-HP-beta-CD depends on the degree of ordering of the solvent and is apparently subject to entropy effects.
(18) Nifedipine (1), a drug practically insoluble in water, has been solubilized employing sodium benzoate (2) and sodium salicylate (3) as hydrotropes.
(19) On the other hand, the hydrotropic salts, sodium benzoate, sodium salicylate, and sodium gentisate, are shown to be the best water solubilizers in 1-butanol.
(20) The behaviour of these hydrotropes as protein denaturants differs from that of neutral electrolytes but is similar to that of concentrated solutions of urea.
