A visible-light photoredox-catalyzed formal [5 + 1] cycloaddition of N-tosyl vinylaziridines with difluoroalkyl halides as unique C1 synthons was developed. The procedure provides an efficient and practical method to synthesize diverse pyridines in moderate to good yields. The reaction underwent a radical-initiated kinetically controlled ring-opening of vinylaziridines and involved a key alpha,beta-unsaturated imine intermediate, followed by an E2 elimination, a 6 pi electrocyclization, and defluorinated aromatization.

Synthesis of fifteen C-4-aroyl-C-5-aryl-N-1-(5 ‘-deoxythymidin-5 ‘-yl)-1,2,3-triazoles have been reported starting from azidation of 5 ‘-p-toluenesulfonyloxythymidine followed by azide-alkene oxidative cycloaddition reaction of the resulted 5 ‘-azido-5 ‘-deoxythymidine with 1,3-diarylpropenones in dimethylformamide (DMF) in the presence of tetra-n-butylammonium hydrogen sulfate (n-Bu4N+HSO4-, TBAHS) as catalyst in 60 to 79% overall yields. Further, they were also synthesized by one pot sequential reaction of tosylated thymidine with sodium azide in DMF and then with 1,3-diarylpropenones in presence of n-Bu(4)N(+)HSO(4)(-)in superior yield of 70 to 95% than 60 to 79% in two step procedure. All fifteen synthesized compounds were screened for theirin vitroantiMycobacterium tuberculosisactivity against sensitive reference strain H37Rv and multi drug resistant (MDR) clinical isolate 591, and found to exhibit minimum inhibitory concentration (MIC) ranging from 2 to 15 mu g/mL, which was equivalent to the MIC of first line anti-tubercular drug streptomycin. All compounds qualify for their drug likeness when their physicochemical parameters were assessed using online MolSoft and Lipinski filter software, except their molecular weight. The cytotoxicity of potent compounds evaluated human monocytic cell line THP-1 by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay was found to be less as compared to the first line drug, isoniazid.

Recently I am researching about ANTIOXIDANT ACTIVITY; PHENOLIC COMPOSITION; TURKISH PROPOLIS, Saw an article supported by the . Published in WILEY in HOBOKEN ,Authors: Keskin, S. The CAS is 94-41-7. Through research, I have a further understanding and discovery of Chalcone. Category: thiazolidines

Orange peel oil contains high amount of d-limonene which is reported to have antidiabetic activity. Propolis contains many biologically active compounds like phenolic acids, flavonoids and terpenes. Because of its rich phenolic composition, antidiabetic activity of propolis has also been shown in literature. Consumption of raw propolis is limited because of its resinous nature. It should be extracted to convert it into consumable form. Ethanol is the most used solvent for this purpose. Ethanol is the limiting factor for propolis consumption either for religious concerns or being harmful for human health. There is an increasing need for new, compatible and healthier solvents for propolis extraction. This is the first paper describing the extraction of propolis with orange peel oil. 1:10 (g/v) ratio was used for extraction. Orange peel oil (OPO), orange peel oil propolis extract (OPOPE) and ethanol propolis extract (EPE) were separately analysed by using GC-MS technique. Total phenolic content of oil and propolis extract was also carried out. Inhibition of alpha-amylase from barley malt with new extract was also reported. It was found that OPOPE was rich in volatile compounds of propolis, phenolic acid derivatives and free fatty acids. It was observed that OPOPE showed higher inhibition on alpha-amylase enzyme (IC50 0.196 mg/mL). It can be concluded that orange peel oil could be used as solvent for preparing propolis extract. Propolis extract obtained with orange peel oil could also be used as complementary medicine for the treatment of type 2 diabetes.

An efficient and flexible synthesis of a new class of chiral bifunctional NHC catalyst has been reported. These new imidazolylidene NHCs, bearing a (thio)urea function as a hydrogen bond donor promoted efficiently highly diastereoselective trans-cyclopentannulation of enals and enones in moderate to good yields (up to 69 % yield) along with excellent enantioselectivity (up to 96 % ee). This methodology could be applied to a large variety of substrates (30 examples).

The chalcone motif can be found in many molecules that contribute to essential biological processes, and many chalcone-containing compounds exhibit potent anti-cancer activity. Here, we synthesized two series of chalcone analogues (3a-s and 6a-s) based on substituting the chalcone B-ring or A-ring with a 4-oxoquinazolin-2-yl group, and then evaluated them for cytotoxic activity in human colorectal HCT-116 and breast cancer MCF-7 cell lines. Compounds 3a-s (in which a 4-oxoquinazolin-2-yl group functioned as the B-ring) were markedly more cytotoxic than compounds 6a-s (in which 4-oxoquinazolin-2-yl group functioned as the A-ring), based on their IC50 values to inhibit proliferation. Compound 3f was found as the most potent among 38 analogues and the mechanism of its cytotoxicity was investigated. Flow cytometry indicated that HCT-116 cells treated with compound 3f resulted in a dose-dependent accumulation of cells in the sub-G1 phase, which is representative of apoptotic cells. Subsequent assays (including Annexin V-FITC/PI, AO-EB, MitoSOX (TM) Red and JC-1 staining) confirmed that 3f exposure induced apoptosis in HCT-116 cells. Immunoblotting analysis indicated that cellular exposure to 3f increased the cleavage of PARP1 and caspases 3, 7, and 9. Taken together, this novel chalcone analogue has a cytotoxic effect on cultured cancer cell-lines that is likely mediated by inducing apoptosis via the mitochondrial death pathway.

One-step synthesis of beta-carboxyl ketones from alpha,beta-unsaturated ketones using CO2 as a feedstock by photoelectro-synergetic catalysis is reported herein. In this ambient system, silica nanowires (SiNWs) electrode not only acts as the working electrode but also harvests extra light energy to promote the reaction. Following a possible two-step single-electron-transfer process, various substrates exhibit good efficiency with up to 98% product yield, and the method shows wide functional group tolerance.

Novel Mannich base derivatives of glabridin were synthesized and their antiproliferative activity were performed along with our previously reported glabridin-chalcone hybrids molecules (GCHMs) against various human cell lines MDA-MB-231 (breast adenocarcinoma), HEK-293 (embryonic kidney cell line), K562 (leukemia), MCF-7 (breast adenocarcinoma), HeLa (cervix adenocarcinoma), HepG2 (hepatocellular carcinoma) and WRL-68 (hepatic carcinoma). The result showed that the glabridin significantly reduced cell proliferation with IC(50)ranges from 3.67 to 58.30 mu M against all the tested cell lines. The remarkable reduction in antiproliferative activity 2′,4′-dimethoxyglabridin and GCHMs compounds with phenolic OH groups protected by methoxy (OCH3) groups suggested that the free OH groups are essential factor for the antiproliferative activity of glabridin and its derivatives. The Mannich base derivatives of glabridin showed moderate activity IC50(2.20->95.78 mu M). Furthermore,in silicotarget identification analysis revealed that AKT1, DECR1 and NOS1 are the potential targets for glabridin and their derivatives.

A set of CB2R ligands, based on the thiophene scaffold, was synthesized and evaluated in in vitro assays. Compounds 8c-i, k, 1, bearing the 3-carboxylate and 2-(adamantan-1-yl)carboxamido groups together with apolar alkyl/aryl substituents at 5-position or at 4- and 5-positions of the thiophene ring possess high CB2R affinity at low nanomolar concentration, good receptor selectivity, and agonistic functional activity. The full agonist 8g, showing the best balance between receptor affinity and selectivity, was tested in vitro in an experimental model of allergic contact dermatitis and proved to be able to block the release of MCP-2 in HaCaT cells at 10 mu M concentration.

We describe an efficient synthesis of 2,4-substituted pyrido[4,3-d]pyrimidin-5(6H)-ones, which involves the acid-promoted cyclization of cyano enamine 15 to afford 2,4-bis(methylthio)pyrido[4,3-d]pyrimidin-5(6H)-one 17 as a key intermediate. Selective displacement of the 4-methylthio group by a wide range of anilines followed by oxidation of the 2-methylthio group and subsequent substitution by amines enabled the synthesis of a variety of 2,4-disubstituted pyrido[4,3-djpyrimidin-5(6H)-ones.
