The self-aggregation and thermodynamic properties of three cationic quaternary ammonium surfactants were investigated. The physicochemical properties of compounds containing quinuclidin-3-ol with even number of carbon atoms (10, 12, and 14) in the hydrophobic tail were measured by conductivity, dynamic light scattering (DLS), and Zeta-potential measurements. DLS and Zeta-potential measurements show a similar size distribution for all surfactants with excellent uniformity, and Zeta-potential increases significantly with increase in the size of hydrocarbon tail. The critical micelle concentration (CMC) and the degree of micelle ionization (beta) were determined using conductivity measurements. The CMC values of surfactants were found to be between 3.4 and 23.8 x 10(-3) M. The standard Gibbs free energy (Delta Gmico) was derived from conductivity measurements and suggests that surfactants containing longer chains spontaneously form micelles. The antioxidative properties of these cationic surfactants were evaluated using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) and oxygen radical absorbance capacity (ORAC) assays. Among the tested samples, N-tetradecyl-3-hydroxyquinuclidinium bromide (QOH-C14) exhibited the highest antioxidative potential (388.30 nmol (TE) equivalents mL(-1)), which was further investigated by the DNA nicking assay.

Chemical Research Letters, May 2021. Redox catalysis has been broadly utilized in electrochemical synthesis.

A new series of azabicyclic benzimidazole-4-carboxamides 2-21 and -carboxylates 22-30 were synthesized and evaluated for binding affinity at serotoninergic 5-HT3 and 5-HT4 receptors in the CNS. Most of the synthesized compounds exhibited high or very high affinity for the 5-HT3 binding site and low to no significant affinity for the 5-HT4 receptor. SAR observations indicated that a halogen atom at the Ii-position and a nitro group at the 7-position of the benzimidazole ring is the best substitution pattern for 5-HT3 affinity and 5-HT3/5-HT4 selectivity, as well as no substitution in this ring. (S)-(-)-N-(Quinuclidin-3-yl)benzimidazo-4-carboxamides 2, 8, and 14 bound at central 5-HT3 sites with high affinity (K-i = 2.6, 0.13, and 1.7 nM, respectively) and excellent selectivity over serotonin 5-HT4 and 5-HT1A receptors (K-i > 1000-10000 dM). Furthermore, these new 5-HT3 receptor ligands were pharmacologically characterized as potent and selective 5-HT3 antagonists in the isolated guinea pig ileum (pA(2) = 9.6, 9.9, and 9.1, respectively).

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.If you’re interested in learning more about 1120-72-5.

YM-53601, a novel squalene synthase inhibitor, suppresses lipogenic biosynthesis and lipid secretion in rodents

1 To better understand how it decreases plasma cholesterol and triglyceride levels, we evaluated the effect of (E)-2-[2-fluoro-2-(quinuclidin-3-ylidene)ethoxy]-9H-carbazole monohydrochloride (YM-53601) on lipogenic biosynthesis in the liver and lipid secretion from the liver in rats and hamsters. 2 Single administration of YM-53601 in cholestyramine-treated rats inhibited triglyceride and free fatty acid (FFA) biosynthesis at a similar dose range to that at which it inhibited cholesterol biosynthesis. YM-53601 inhibited both triglyceride and FFA biosynthesis in hamsters treated with cholestyramine. 3 YM-53601 by single oral administration decreased the enhanced plasma triglyceride levels in hamsters induced by an injection of protamine sulfate, which inhibits lipoprotein lipase (LPL) and consequently increases plasma very low-density lipoprotein (VLDL) triglyceride levels. YM-53601 also decreased the enhanced plasma triglyceride and cholesterol levels in hamsters treated with Triton WR1339, which also inhibits the degradation of VLDL. Plasma cholesterol was significantly decreased as soon as I h after single administration of YM-53601 in hamsters fed a normal diet. 4 This is the first report that a squalene synthase inhibitor suppresses lipogenic biosynthesis in the liver and cholesterol and triglyceride secretion from the liver in vivo. We therefore suggest that the mechanism by which YM-53601 decreases plasma triglyceride might include these effects. The finding that YM-53601 rapidly decreased plasma cholesterol suggests that this compound may be effective in decreasing plasma cholesterol levels early in the course of treatment of hypercholesterotemia in humans.
