Synthetic Route of 50717-82-3, In heterogeneous catalysis, the catalyst is in a different phase from the reactants. At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 50717-82-3, name is Piperidin-3-one. In an article，Which mentioned a new discovery about 50717-82-3

Starting with our previously described20 class of CC chemokine receptor-3 (CCR3) antagonist, we improved the potency by replacing the phenyl linker of 1 with a cyclohexyl linker and by replacing the 4-benzylpiperidine with a 3-benzylpiperidine. The resulting compound, 32, is a potent and selective antagonist of CCR3. SAR studies showed that the 3-acetylphenyl urea of 32 could be replaced with heterocyclic ureas or heterocyclic-substituted phenyl ureas and still maintain the potency (inhibition of eotaxin-induced chemotaxis) of this class of compounds in the low-picomolar range (IC50 = 10-60 pM), representing some of the most potent CCR3 antagonists reported to date. The potency of 32 for mouse CCR3 (chemotaxis IC50 = 41 nM) and its oral bioavailability in mice (20% F) were adequate to assess the efficacy in animal models of allergic airway inflammation. Oral administration of 32 reduced eosinophil recruitment into the lungs in a dose-dependent manner in these animal models. On the basis of its overall potency, selectivity, efficacy, and safety profile, the benzenesulfonate salt of 32, designated DPC168, entered phase I clinical trials.

Tetrahydronaphthalene as a precursor of new series of chalcones, flavanones, and flavones

An efficient synthetic route for a novel series of chalcones 2a-2d as well as for the corresponding flavanones 3a-3d and flavones 4a-4d, using functionalized tetrahydronaphthalene (THN), is described herein. The Claisen-Schmidt condensation of such THN and aromatic aldehydes, in the presence of an aqueous solution of KOH (40%), selectively gives the expected chalcones 2a-2d, which may further undergo an intramolecular oxa-Michael addition using piperidine, affording the corresponding flavanones 3a-3d in high yields. Alternatively, treatment of such chalcones 2a-2d with I-2/DMSO provides rapidly, in a one-pot oxidative cyclization, a series of flavones 4a-4d in excellent yields ranging from 85% to 90%.

Synthesis of ERB-1 by a steam-environment crystallization method and further application in the post-synthesis of Ti-MWW zeolite

Sustainable synthesis of MWW zeolites have been the focus of attention but still a significant challenge. In this study, an innovative synthesis strategy of the EniRicerche-Boralite-1 (ERB-1) precursor is reported via an interesting steam-environment crystallization method (SEC). Compared with the conventional hydrothermal synthesis, this method not only simplified the synthetic process but also reduced 85% amount of boric acid and solvent and half amount of the piperidine (PI, SDA, structure-directing agent). Moreover, the crystallization time was also reduced from 7 d to 2 d. The Ti-MWW prepared with this ERB-1 precursor showed the same catalytic performance as typical post-synthesized Ti-MWW (Ti-MWW-PS) in the liquid-phase epoxidation of 1-hexene with H2O2. XRD and SEM techniques explained the effects of boron content and crystallization time on the preparation of ERB-1. The physicochemical properties of the ERB-1 and corresponding Ti-MWW in different preparation conditions were investigated systematically by the FT-IR, UV-vis, ICP, NH3-TPD and N-2 absorption-desorption techniques. This method is both eco-friendly for the synthesis of ERB-1 and effective for the preparation of MWW-type zeolites in industrial production on a large scale in the future.

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. you can also check out more blogs about 108-26-9. HPLC of Formula: C4H6N2O.

The genus Cassia L.: Ethnopharmacological and phytochemical overview

Nature gifts medicinal plants with the untapped and boundless treasure of active chemical constituents with significant therapeutic potential that makes these plants a beneficial source in the development of phytomedicines. Genus Cassia, with approximately 500 species, is a large group of flowering plants in the family Fabaceae. Cassia species are widely distributed throughout different regions mainly tropical Asia, North America, and East Africa. In the folk medicinal history, these plants are used as laxative and purgative agents. In the Ayurveda system of medicine, they are used to cure headache and fever. Cassia plants exhibit pharmacological activities at large scales such as antimicrobial, anticancer, antiinflammatory, antioxidant, hypoglycemic, hyperglycemic, antimutagenic, and antivirals. The phytochemical investigations of genus Cassia demonstrate the presence of more than 200 chemical compounds, including piperidine alkaloids, anthracene derivatives (anthraquinones), flavonoids, pentacyclic triterpenoids, sterols, phenylpropanoids, and gamma-naphthopyrones. The literature illustrated anthraquinones and flavonoids as major secondary metabolites from this genus. However, some Cassia plants, with rich contents of anthraquinones, still show toxicology properties. As Cassia plants are used extensively in the herbal system of medicine, but only senna dosage forms have achieved the status of the pharmaceutical market as standard laxative agents. In conclusion, further investigations on isolating newer biologically active constituents, unknown underlying mechanisms, toxicology profiles, and clinical studies of Cassia species are needed to be explored. This review article specifies the systematic breach existing between the current scientific knowledge and the fundamentals for the marketization of genus Cassia products.

Regioselective Bronsted Acid-Catalyzed Annulation of Cyclopropane Aldehydes with N’-Aryl Anthranil Hydrazides: Domino Construction of Tetrahydropyrrolo[1,2-a]quinazolin-5(1H)ones

A highly regioselective synthesis of tetrahydropyrrolo[1,2-a]quinazolin-5(1H)one derivatives was achieved by reacting cyclopropane aldehydes with N’-aryl anthranil hydrazides in the presence of p-toluene sulfonic acid (PTSA). The transformation involves domino imine formation and intramolecular cyclization to form 2-arylcyclopropyl-2,3-dihydroquinolin-4(1H)-one, followed by nucleophilic ring opening of the cyclopropyl ring to form desired tetrahydropyrrolo [1,2-a]quinazolin-5(1H) one in good to excellent yield with complete regioselectivity. This protocol tolerates a great variety of functional groups and thus provides a simple and step-efficient method for pyrroloquinazolinone synthesis.

Strategy for Designing Selective Lysosomal Acid alpha-Glucosidase Inhibitors: Binding Orientation and Influence on Selectivity

Deoxynojirimycin (DNJ) is the archetypal iminosugar, in which the configuration of the hydroxyl groups in the piperidine ring truly mimic those ofd-glucopyranose; DNJ and derivatives have beneficial effects as therapeutic agents, such as anti-diabetic and antiviral agents, and pharmacological chaperones for genetic disorders, because they have been shown to inhibit alpha-glucosidases from various sources. However, attempts to design a better molecule based solely on structural similarity cannot produce selectivity between alpha-glucosidases that are localized in multiple organs and tissues, because the differences of each sugar-recognition site are very subtle. In this study, we provide the first example of a design strategy for selective lysosomal acid alpha-glucosidase (GAA) inhibitors focusing on the alkyl chain storage site. Our design of alpha-1-C-heptyl-1,4-dideoxy-1,4-imino-l-arabinitol (LAB) produced a potent inhibitor of the GAA, with an IC(50)value of 0.44 mu M. It displayed a remarkable selectivity toward GAA (selectivity index value of 168.2). A molecular dynamic simulation study revealed that the ligand-binding conformation stability gradually improved with increasing length of the alpha-1-C-alkyl chain. It is noteworthy that alpha-1-C-heptyl-LAB formed clearly different interactions from DNJ and had favored hydrophobic interactions with Trp481, Phe525, and Met519 at the alkyl chain storage pocket of GAA. Moreover, a molecular docking study revealed that endoplasmic reticulum (ER) alpha-glucosidase II does not have enough space to accommodate these alkyl chains. Therefore, the design strategy focusing on the shape and acceptability of long alkyl chain at each alpha-glucosidase may lead to the creation of more selective and practically useful inhibitors.

MOLECULAR DOCKING AND TOXICITY STUDIES OF SERIES OF COMPOUNDS FROM DIARYL UREA HITS & SPIRO PIPERIDINE INDOLINYL SERIES AS POTENTIAL P2Y1 RECEPTOR ANTAGONISTS

Scientific investigations revealed that the study of P2Y1 receptors is very much essential in the current scenario because of their potential role in related to various disorders/diseases like thrombosis, cardiovascular problems. P2Y1 receptors belong to G protein-coupled receptors, an important target for ADP induced platelet aggregation. Blockade of P2Y1 receptors leads to the treatment of thrombosis with a potentially improved safe margin. Hence, it is essential to select targeted molecules as P2Y1 receptor antagonists. The present work is to explore P2Y1 receptor antagonists from different series of synthetic compounds by using docking, virtual screening, and toxicity studies. Docking studies were performed and scored to evaluate ligand binding affinities. The present work could be used as a tool to show how different scaffold structures are utilized for the development of suitable P2Y1 receptor antagonists for platelet aggregation activity.
