Acetamide Derivatives of Chromen-2-ones as Potent Cholinesterase Inhibitors

Alzheimer’s disease (AD), a neurodegenerative disorder, is a serious medical issue worldwide with drastic social consequences. Inhibition of cholinesterase is one of the rational and effective approaches to retard the symptoms of AD and, hence, consistent efforts are being made to develop efficient anti-cholinesterase agents. In pursuit of this, a series of 19 acetamide derivatives of chromen-2-ones were synthesized and evaluated for their acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibitory potential. All the synthesized compounds exhibited significant anti-AChE and anti-BChE activity, with IC50 values in the range of 0.24?10.19 muM and 0.64?30.08 muM, respectively, using donepezil hydrochloride as the standard. Out of 19 compounds screened, 3 compounds, viz. 22, 40, and 43, caused 50% inhibition of AChE at 0.24, 0.25, and 0.25 muM, respectively. A kinetic study revealed them to be mixed-type inhibitors, binding with both the CAS and PAS sites of AChE. The above-selected compounds were found to be effective inhibitors of AChE-induced and self-mediated Abeta1?42 aggregation. ADMET predictions demonstrated that these compounds may possess suitable blood?brain barrier (BBB) permeability. Hemolytic assay results revealed that these compounds did not lyse human RBCs up to a thousand times of their IC50 value. MTT assays performed for the shortlisted compounds showed them to be negligibly toxic after 24 h of treatment with the SH-SY5Y neuroblastoma cells. These results provide insights for further optimization of the scaffolds for designing the next generation of compounds as lead cholinesterase inhibitors.

Because enzymes can increase reaction rates by enormous factors and tend to be very specific, category: piperidines, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 50541-93-0

Multicomponent reactions for facile access to coumarin-fused dihydroquinolines and quinolines: Synthesis and photophysical studies

A simple and straightforward method for facile access to coumarin-fused dihydroquinolines (4) has been developed using the microwave-assisted multicomponent reactions of 4-hydroxycoumarin, aldehydes and aromatic amines in water catalyzed by bismuth triflate. Under solvent-free and conventional heating conditions, the same combination provided the corresponding coumarin-fused quinolines (5). An alternative and rapid method for the conversion of (4) to (5) with very good yields was also developed using N-bromosuccinamide. Single-crystal X-ray crystallographic analysis of one of the products (4q) showed that the products are regioselective and that the reactions proceed via 1,2-addition followed by 6pi-electrocyclization instead of a Skraup-Doebner-von Miller type reaction. Substituted quinoline carboxylic acid derivatives (7) were synthesized selectively from (4) by ring opening of the coumarin moiety followed by aromatization using NaOH/DMSO under reflux conditions. Considering the presence of the polycyclic conjugated structure of the synthesized compounds 4 and 5 with the coumarin moiety, preliminary photophysical studies were carried out and promising quantum yields were observed along with a maximum quantum yield (of = 0.65) for 4j.

Pharmacokinetics of flavoxate in rats

The plasma levels, the urinary excretion and the biliary excretion of piperidinoethyl 3 methylflavone 8 carboxylate (flavoxate, F) were studied in rats after i.v. and after oral administration. Parallel experiments were made with 3 methyl flavone 8 carboxylic acid (M), the main metabolite of F. The substances are found in blood and are excreted in the urine and in the bile. The quantities excreted in the urine after oral administration are similar to those excreted after i.v. administration, showing that the enteric availability of the drugs is almost complete. The end product in urine and in bile is represented by a substance which yields M after a strong acid hydrolysis. There are marked pharmacokinetic differences between F and M, probably related to their physical properties.

Synthesis and structure-activity relationships for new 6-fluoroquinoline derivatives with antiplasmodial activity

The substitution of 6-fluoroquinolines was modified in ring positions 2 and 4. The new compounds were tested in vitro for their activities against a sensitive and a multidrug resistant strain of Plasmodium falciparum. Some physicochemical parametres were calculated (log P, log D, ligand efficiency) or determined experimentally (permeability). The most promising compounds were tested for their in vivo activity against Plasmodium berghei in a mouse model. The 6-fluoro-2-{4-[(4-methylpiperazin-1-yl)methyl]phenyl}-N-[2-(pyrrolidin-1-yl)ethyl]quinoline-4-carboxamide possessed proper physicochemical properties and showed high antiplasmodial activity in vitro (IC50 ? 0.0029 muM) and in vivo (99.6% activity).

Kinetics and new Br?nsted correlations study of CO2 absorption into primary and secondary alkanolamine with and without steric-hindrance

To figure out the steric hindrance and its magnitude effects on CO2 absorption performance and Br¡ãnsted correlations of primary and secondary alkanolamines, the pKa values and kinetics data (second order reaction rate, k2) were investigated for nine alkanolamines at 293?313 K using pH meter and stopped-flow technique. The tested amines include monoethanolamine (MEA), diethanolamine (DEA), 2-methyl-ethynolamine (MAE), 2-ethyl-ethynolamine (EAE), 1-amino-2-propanol (1-AP), 3-amino-1-propanol (3-AP), 2-amino-2-methyl-1-propanol (AMP), 2-amino-1-propanol (2-AP) and 3-Amino-1,2-propanediol (3-APD). In addition, the equilibrium solubility of MEA, MAE, EAE, 2-AP and AMP were tested for evaluation of steric hindrance effect on carbamate’s stability. The comprehensive analysis of kinetics, solubility and Br¡ãnsted correlations indicated that the steric hindrance caused by alkyl group(s) attached to alpha-C atom has much significant effect on k2 and solubility than that caused by alkyl group connected to amino group. Moreover, the k2 and pKa values for sterically unhindered and hindered amines were separately fitted at 293?313 K, giving out an AARD of 5.2% and 16.5% between predicted and experimental k2, respectively. Finally, based on molecular structures and experimental results, mechanism of steric hindrance effect on reaction kinetics was proposed.
