Design of more potent squalene synthase inhibitors with multiple activities

With the increasing realization that modulating a multiplicity of targets can be an asset in the treatment of multifactorial disorders, we hereby report the synthesis and evaluation of the first compounds in which antioxidant, anti-inflammatory as well as squalene synthase (SQS) inhibitory activities are combined by design, in a series of simple molecules, extending their potential range of activities against the multifactorial disease of atherosclerosis. The activity of the initially synthesized antihyperlipidemic morpholine derivatives (1-6), in which we combined several pharmacophore moieties, was evaluated in vitro (antioxidant, inhibition of SQS and lipoxygenase) and in vivo (anti-dyslipidemic and anti-inflammatory effect). We further compared the in vitro SQS inhibitory action of these derivatives with theoretically derived molecular interactions by performing an in silico docking study using the X-ray crystal structure of human SQS. Based on low energy preferred binding modes, we designed potentially more potent SQS ligands. We proceeded with synthesizing and evaluating these new structures (7-12) in vitro and in vivo, to show that the new derivatives were significantly more active than formerly developed congeners, both as SQS inhibitors (20-70-fold increase in activity) and antioxidants (4-30-fold increase in activity). A significant correlation between experimental activity [Log(1/IC50)] and the corresponding binding free energy (DeltaGb) of the docked compounds was shown. These results, taken together, show a promising alternative and novel approach for the design and development of multifunctional antiatherosclerosis agents.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 3433-37-2, and how the biochemistry of the body works.3433-37-2

Pyridonepezils, new dual AChE inhibitors as potential drugs for the treatment of Alzheimer’s disease: Synthesis, biological assessment, and molecular modeling

The synthesis, biological assessment and molecular modeling of new pyridonepezils 1-8, able to inhibit human acetylcholinesterase (hAChE) and human butyrylcholinesterase (hBuChE), are described. The new compounds have been designed as hybrids resulting from a conjunctive approach that combines the N-benzylpiperidine moiety, present in donepezil, and the 2-amino-6- chloropyridine heterocyclic ring system, connected by an appropriate polymethylene linker. Compounds 1-8 were prepared by reaction of 2-amino-6-chloro-4-phenylpyridine-3,5-dicarbonitrile (13) [or 2-amino-6-chloropyridine-3,5-dicarbonitrile (14)] with 2-(1-benzylpiperidin-4- yl)alkylamines (9-12). The biological evaluation of molecules 1-8 showed that compounds 1-6 are potent AChE inhibitors, in the submicromolar, while compounds 7 and 8 are on the nanomolar range, the most potent, 2-amino-6-((3-(1- benzylpiperidin-4-yl)propyl)amino)pyridine-3,5-dicarbonitrile (7), showing a IC50 (hAChE) = 9.4 ¡À 0.4 nM. Inhibitors 2-8 are permeable as determined in the PAMPA assay. Compared to donepezil, compound 7 is in the same range of inhibitory activity for hAChE, and 703-fold more selective for hAChE than for hBuChE. Molecular modeling investigation on pyridonepezil 7 supports its dual AChE inhibitory profile, binding simultaneously at the catalytic active and at peripheral anionic sites of the enzyme. The theoretical ADME analysis of pyridonepezils 1-8 has been carried out. Overall, compound 7, a potent and selective dual AChEI, can be considered as a candidate with potential impact for further pharmacological development in Alzheimer’s therapy.

Synthesis and characterization of Co3O4 immobilized on dipeptide-functionalized silica-coated magnetite nanoparticles as a catalyst for the selective aerobic oxidation of alcohols

Synthesis and characterization of a new silica-coated magnetite nanocatalyst are described. This catalyst was prepared through a multistep procedure consisting of surface modification, functionalization with the product of an Ugi multicomponent reaction, and immobilization of Co3O4 on silica-coated magnetite nanoparticles. The prepared nanocatalyst was characterized using various techniques such as Fourier-transform infrared and energy-dispersive X-ray spectroscopies, thermal and elemental analyses, X-ray diffraction, and field-emission scanning and transmission electron microscopies. The catalyst showed high catalytic activity for the aerobic oxidation of alcohols in acetonitrile as the solvent at mild temperatures and reusability for five repeated runs without loss of its activity.

Formation of electrosprayed composite nanoparticles from polyvinylpyrrolidone/mangosteen pericarp extract

Mangosteen pericarp contains a lot of alpha-mangostin compounds which has very high antioxidant activity. Unfortunately, it has a low solubility in aqueous solution in which for drug delivery application. This paper reports the synthesis of polyvinylpyrrolidone (PVP) nanoparticles loaded with mangosteen pericarp extract (MPE) using the ES method. PVP was trusted as a hydrophilic matrix to carry MPE. The composition of the precursor solution and solution flow rate during the ES process were varied to control the formation of PVP/MPE composite nanoparticles. PVP/MPE composite particles obtained have some wrinkles on their surface and have a geometric average diameter range of 640 to 1534 nm with a geometric standard deviation of 1.35 to 1.65. Increasing the electrical conductivity of the precursor solution resulted in a decrease of nanoparticles’ average diameter. Also, the greater the flow rate, the larger the particles formed. The results agreed well with the droplet scaling relations for EHDA by Chen and Pui. Peak shifts in Fourier-transform infrared spectra of PVP/MPE composite nanoparticles indicated hydrogen bond formation between PVP and MPE. It also showed that MPE was successfully encapsulated in PVP matrix. Crystalline peaks of MPE disappear in the X-ray diffraction patterns of PVP/MPE composite nanoparticles, indicating amorphization of MPE after being electrosprayed by PVP. The differential scanning calorimetry study confirmed a hygroscopicity of PVP. The thermogram shows a broad endothermic peak from around 50 to 100 C as a result of dehydration. In this study, the use of flow rate during the electrospraying process only affected the geometric average diameter, did not change the functional groups, thermal properties, and crystallinity of PVP/MPE particles because they came from the same precursor solution. The results here demonstrate that the ES method can be used for polymeric-nanoparticle-composite production and as an innovation in the field of drug delivery application.
