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%.

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.

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.

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.

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.

Amine complexes of gold, part 10: gold(I) thiocyanate complexes with tetrahydrothiophene, dimethyl sulfide, ammonia, amines and azaaromatics

The reaction of (tht) AuCl (tht = tetrahydrothiophene) with KSCN leads to a mixture of gold(I) thiocyanate AuSCN and [(tht)(2)Au](+) [Au(SCN)(2)](-) 1. The compounds were separated and the X-ray structure of 1 confirmed as an alternating chain of anions and cations linked by aurophilic contacts. Either pure AuSCN or the mixture was used to synthesize further derivatives of AuSCN, all of which were investigated by X-ray methods. Most products were of limited stability when removed from their mother liquor. The dimethyl sulfide derivative 2 is molecular, (Me2S) AuSCN; the ammonia derivative 3 is ionic, [(NH3)(2)Au](+) [Au(SCN)(2)](-). The reaction with 2,2-bipyridyl leads (presumably by involvement of the solvent or of atmospheric moisture) to [bipy-H](+) [Au(SCN)(2)](-) 13. All other products involve amines or azaaromatics as ligands L. The primary amine tert-butylamine forms an ionic product [L2Au](+) (SCN)(-) 4. The secondary amines piperidine and dibenzylamine lead to molecular structures LAuSCN (5 and 6), whereas pyridine-based azaaromatics lead to ionic products [L2Au](+) [Au(SCN)(2)](-) with L = 2-, 3- or 4-picoline (7-9), 2,4-, 3,4- or 3,5-lutidine (10-12). The 3,4-lutidine derivative 11 forms two polymorphs that tend to form mixed crystals. The dominant features of the crystal packing for 7-12 are short aurophilic interactions.

Developing a Novel Gold(III) Agent to Treat Glioma Based on the Unique Properties of Apoferritin Nanoparticles: Inducing Lethal Autophagy and Apoptosis

Effective delivery of anticancer agents across the blood-brain barrier (BBB) required innovative strategies to achieve glioma regression. To resolve this problem, we proposed to develop a metal agent that target and treat glioma based on the unique property of apoferritin (AFt) nanoparticles (NPs). Thus, we synthesized a series of Au(III) 3-(4-metyl piperidine)-thiosemicarbazides compounds and analyzed their structure-activity relationships, obtaining a Au agent (C6) with remarkable cytotoxicity in glioma. Moreover, we confirmed that C6 kills glioma cells by inducing lethal autophagy and apoptosis. Importantly, our results revealed that the successfully constructed apoferritin-C6 NPs (AFt-C6 NPs) can effectively cross the BBB, inhibit glioma growth, and selectively accumulate in tumors.

Synthesis of Various Derivatives of [1,3]Selenazolo[4,5-d]pyrimidine and Exploitation of These Heterocyclic Systems as Antibacterial, Antifungal, and Anticancer Agents

A number of diversely functionalized derivatives of a novel [1,3]selenazolo[4,5-d]pyrimidine have been synthesized through heterocyclization of some 2,4,5-trisubstituted-1,3-selenazoles with orthoesters in refluxing acetic acid. The synthetic compounds were evaluated for their antimicrobial activity against a panel of microorganisms including Gram-negative bacteria, Gram-positive bacteria, and pathogenic fungi. The antifungal results revealed that the new selenium-containing heterocycles were as good as or sometimes better than terbinafine and fluconazole. The in vitro anticancer activities of aforementioned heterocyclic compounds were screened against human breast carcinoma MCF-7 and HeLa cervical cancer cells as well as HDF (human dermal fibroblast) normal cells. Antiproliferative results indicated that compounds with piperidine moiety on MCF-7 cells and with morpholine moiety on HeLa cells exhibited well broad-spectrum of anticancer activities with 397, 298 and 235 mu M and 533, 390 and 204 mu M of IC(50)values after 24, 48 and 72 h of treatments, respectively, while they had no significant toxic effects on normal cells.
