Robust organogels from nitrogen-containing derivatives of (R)-12-hydroxystearic acid as gelators: comparisons with gels from stearic acid derivatives.
Thirteen members of a new class of low molecular-mass organogelators (LMOGs), amides, and amines based on (R)-12-hydroxystearic acid (HSA; i.e., (R)-12-hydroxyoctadecanoic acid) and the properties of their gels have been investigated by a variety of structural and thermal techniques. The abilities of these LMOGs, molecules with primary and secondary amide and amine groups and the ammonium carba...
متن کاملSolutol HS 15, nontoxic polyoxyethylene esters of 12-hydroxystearic acid, reverses multidrug resistance.
A recently developed non-ionic surfactant called Solutol HS 15 (poly-oxyethylene esters of 12-hydroxystearic acid), with low toxicity in vivo, was shown to reverse completely the multidrug resistance of KB 8-5 and KB 8-5-11 human epidermoid carcinoma cells in vitro but did not potentiate drug toxicity in drug-sensitive KB 3-1 cells. At a concentration of 10% of its own IC50 (mean concentration ...
متن کاملOscillatory Rheology and Surface Water Wave Effects on Crude Oil and Corn Oil Gels with (R)‐12-Hydroxystearic Acid as Gelator
The mechanical properties of films of gels composed of a crude oil or corn oil and (R)-12-hydroxystearic acid are described using oscillatory rheology and water-surface waves. The integrity of these gel films are contrasted with those of neat oil films subjected to the same types of mechanical testing. The oil-based gels are thixotropic, and we quantify their post-recovery yield. A simple model...
متن کاملHydroxystearic acid and diarrhoea following ileal resection.
The faecal outputs of 10 patients who complained of diarrhoea after ileal resection were measured whilst they consumed identical diets in which most of the fat was present as olive oil. No relationship was found between faecal weight and hydroxystearic acid production. In three patients the output of hydroxystearic acid was reduced by changing the dietary fat. There was no reduction in faecal w...
متن کاملPreparation of silicotungstenic acid-containing mesoporous materials.
Silicotungstenic acid (STA)-containing mesoporous materials were directly synthesized in a nonaqueous medium by sol-gel method. X-ray powder diffraction showed that both as-synthesized and calcined materials possess mesoporous structure. STA contents in extraction solutions were analyzed with inductively coupled plasma. When STA/silica ratio changed from 1:100 to 1:4, the immobilization of STA ...
