Journal ArticleDOI
Plantas medicinais: a necessidade de estudos multidisciplinares
Maria Aparecida Medeiros Maciel,Angelo C. Pinto,Valdir F. Veiga,Noema F. Grynberg,Aurea Echevarria +4 more
TL;DR: The chemical composition and pharmacological properties of the very efficient medicinal plant Croton cajucara were investigated according to ethnopharmacological approaches and proved to be both efficient and successful.
Journal ArticleDOI
Experimental and theoretical evaluation of semicarbazones and thiosemicarbazones as organic corrosion inhibitors
Carla Marins Goulart,Andressa Esteves-Souza,Carlos A. Martínez-Huitle,Ciro José Ferreira Rodrigues,Maria Aparecida Medeiros Maciel,Aurea Echevarria +5 more
TL;DR: In this article, the performance of four thiosemicarbazones (1A,D) and two semicarbazone (2A,B) towards carbon steel corrosion in 1.0 M HCl was evaluated by molecular modeling, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) at different inhibitor concentrations.
Journal ArticleDOI
Antileishmanial pyrazolopyridine derivatives: synthesis and structure-activity relationship analysis.
Heloisa de Mello,Aurea Echevarria,Alice M. R. Bernardino,Marilene M. Canto-Cavalheiro,Leonor L. Leon +4 more
TL;DR: Three series of 4-anilino-1H-pyrazolo[3,4-b]pyridine-5-carboxylic esters were synthesized as part of a program to study potential anti-Leishmania drugs and showed the 3'-diethylaminomethyl-substituted compounds as the most active.
Journal ArticleDOI
Ethnopharmacology, phytochemistry and pharmacology: a successful combination in the study of Croton cajucara.
Maria Aparecida Medeiros Maciel,Angelo C. Pinto,Alberto C Arruda,Sônia G.S.R. Pamplona,Frederico Argollo Vanderlinde,Antonio José Lapa,Aurea Echevarria,Noema F. Grynberg,Ilce Mara de Syllos Cólus,Rômulo A.F Farias,Angelica M Luna Costa,Vietla Satyanarayana Rao +11 more
TL;DR: The effects of DCTN and CTN on the survival of mice bearing Sarcoma 180 and Ehrlich carcinoma ascitic tumors, on the proliferation of cultured cells and TNFalpha were determined and the terpenoids, DCTn and AAA, and the chloroform extract of 6-month-old plants reduced gastrointestinal transit in mice.
Journal ArticleDOI
A solid-state NMR, X-ray diffraction, and ab initio computational study of hydrogen-bond structure and dynamics of pyrazole-4-carboxylic acid chains.
Concepción Foces-Foces,Aurea Echevarria,Nadine Jagerovic,Ibon Alkorta,José Elguero,Uwe Langer,Oliver Klein,María Minguet-Bonvehí,Hans-Heinrich Limbach +8 more
TL;DR: Using high-resolution solid-state (15)N CMAS NMR, X-ray crystallography, and ab initio calculations, the structure of solid pyrazole-4-carboxylic acid is studied, which shows a proton disorder-order transition where the protons are preferentially localized on given nitrogen and oxygen atoms.
