The antioxidant activities of the ethanol extract, its benzene and chloroform fraction from seed aril of Myristica malabarica (Myristicaceae) were assessed in an effort to validate the hepatoprotective potency of this plant. The extract and the fractions showed scavenging of 1, 1-diphenyl-2picrylhydrazyl (DPPH) radical and inhibition of ABTS radical in vitro. Antioxidant activities of the extra...

Following on the heels of remarkable lead halide perovskite optoelectronic materials, interest in lead-free perovskites has grown rapidly past decade. Double halides with general formula A2MIMIIIX6 (where A is a large monovalent cation site, MI univalent metal, MIII trivalent and X halide) represent one promising classes such these, iodides are particularly interesting since their band gaps exp...

Background and Aims: The Clusiaceae family is known for its bioactive compounds with beneficial antioxidant anti-inflammatory properties. objectives of this study were to 1) identify quantify the individual polyphenol in methanolic extract from peel, pulp aril fruit Clusia quadrangula by UPLC-MSMS, evaluate their properties, 2) analyze fatty acid profile, minerals composition 3) determine antib...

A photoinduced reaction between TMDPO (diphenyl(2,4,6-trimethylbenzoyl)-phosphine oxide) and perfluoroalkyl iodides successfully affords P-(perfluoroalkyl)diphenylphosphines as promising ligands for recyclable catalysts. Interestingly, the perfluoroalkylation reaction involves the reduction of phosphorus(V) compounds to phosphorus(III) species. The advantages of the present reaction include the...

The carbamate (-O2CNR2) function is an excellent directing group for palladium-catalysed direct arylation reactions giving both protected or free mono- or di-substituted phenols, as well as an example of a dibenzopyranone, depending on coupling partners (aryl iodides or diaryliodonium salts) and conditions.

A new, mild, and environment friendly process for the reduction of S-alkyl-thionocarbonates, iodides and related compounds to the corresponding hydrocarbons at room temperature with good to excellent yields is described. This method uses a trialkylborane in excess (Et3B or Bu3B) and air.

A palladium-catalyzed difluoromethylation of a series of heteroaryl chlorides, bromides and iodides under mild conditions is described. A wide range of heteroaryl halides such as pyridyl, pyrimidyl, pyrazyl, funanyl, thienyl, pyazolyl, imidazolyl, thiazolyl, and oxazolyl halides were efficiently difluoromethylated, thus providing medicinal chemists an alternative choice for the preparation of d...

A highly regio- and stereo-selective synthesis of cyclic β-D-glucosides 3 via Pd(0)-catalyzed coupling cyclization of allenyl β-D-glucoside 1 and organic iodides in 20-38% yields is reported. After the deacetylation of 3, we obtained cyclic β-D-glucoses 4 in 90-97% yields, which may have SGLT2 inhibition activities.
