A DLLME-GC/ECD was optimized and validated to analyze the parathion-methyl in water and evaluate its UV-photodegradation.

A new series of heterocycles were synthesized. Some of these compounds were evaluated for their anti-hyperglycemic and renoprotective activity.

Application of metal-modified cellulose as ligand in heterogeneous catalytic systems of coupling reactions as a new option for green and sustainable chemistry.

This paper is part of the PubliSBQ Special Issue in honor of the late Prof Angelo da Cunha Pinto.

Synthesis of coordination polymer [Zn(aip)(DMSO)] (aip: 5-aminoisophthalate and DMSO: dimethylsulfoxide) using several synthetic conditions, which show the high stability and structural invariance of the network.

Fast inactivation of C. parapsilosis by photoelectrocatalysis. The attack of HO∙ radicals to the cell wall of the fungus promotes rapid death and high degradation of organic compounds from the cell lyse. Photoelectrocatalysis is an efficient alternative to threat wastewater with high chloride content containing fungus.

A fast, simple, inexpensive and green flow analysis procedure for the determination of gossypol in cottonseed meal.

Lipophilicity parameters for 1-(benzofuran-2-yl)ethan-1-one oxime and its nine biological active ethers were evaluated using reversed phase high performance liquid chromatography (RP-HPLC) method. The log k_w lipophilicity parameters were compared with computed log P values using methanol, 2-propanol and acetonitrile as organic modifier of the mobile phases.

New ethylene-spaced biheterocyclic 5-[2-(trifluoromethyl heteroaryl)-ethyl]-1,3,4-oxadiazoles were synthesized by two consecutive cyclocondensations from methyl 7,7,7-trifluoro-4-methoxy-6-oxo-4-heptenote derived from the renewable levulinic acid.

A new ruthenium nitrosyl complex containing benzoylpyridine ligand showed promising visible light induced release of NO and vasodilation activity.

Experimental and computational data: a robust protocol to complete ¹³C NMR chemical shifts assignment of substituted chalcones.

The image depicts the first step of sample preparation process starting from the extraction of volatile perfume by solid phase microextraction (SPME) in headspace mode with subsequent identification and quantification by gas chromatography mass spectrometry (GC-MS).

Wastewater analyses indicate high cocaine consumption during Soccer World Cup as well as different forms of used cocaine.

Natural α,β-amyrin mixtures isolated from Esenbeckia grandiflora were transformed into aminoesters and their cytotoxic activities were evaluated against PC-3, HCT-116 and HL-60 tumor cells. Diethyl, aniline, morpholine and imidazole derivatives showed moderate activity against HL60.

The metal content across dissolution profiles of five multivitamin supplements was evaluated by inductively coupled plasma optical emission spectrometry (ICP OES).

Picric acid loaded iron oxide nanoparticles were retained on HPLC (high-performance liquid chromatography) syringe disk and used as SPE (solid phase extraction) sorbent for perphenazine pre-concentration and clean up.

What is the influence of substituents on methoxy-chalcones? A combined structural and theoretical investigation.

Synthesis of the resin after diazotization and the mechanisms of removal of bisphenol-A by adsorption and enzymatic oxidation.

Corncob husk biomass requires low input of energy on pyrolysis to be produced and it is an indicator for worthy carbon based biofuels. Some biochars are prone to oxidation reactions.

Rice husk ash was used to synthesize a silicon and potassium slow-release fertilizer. The method is an attractive way of enabling the reuse of a waste.

Chiral bis(7)-tacrine compounds were synthesized in yields ranging from 40 to 80%. Both enantiomeric series were found to be potent AChE and BuChE inhibitors in vitro, with IC₅₀ values ranging from 2 to 16 nM and from 30 to 140 nM, respectively.

A new subclass of 8,4'-oxyneolignans presented a promising antiproliferative activity against human cancer cells.

Glycerol products in volatile fraction and condensed fraction using niobium oxyhydroxide as catalyst.

HT-LiCoO₂ synthesized by sol-gel method with the citric acid, starch, glycine and gelatin complexing agents to obtain the rhombohedral crystalline system of the R m space group.

The rate coefficient of the cis-3-hexene + Cl atoms reaction was determined by the relative rate technique using trichloroacetyl chloride to produce chlorine atoms.

A new pyranone and three new aristolochic acid derivatives were isolated from Aristolochia urupaensis stems together with 31 known compounds.
