Modelagem Molecular (TD-DFT) aplicada na predição do fator de proteção solar de compostos naturais

Na área da saúde pública, as doenças provocadas pela radiação solar têm ganho grande destaque, por serem cada vez mais comuns. Dentre as principais formas de prevenção a utilização de filtros solares são as mais comuns e de fácil acesso. Os filtros utilizados atuam por sua capacidade de refl...

Poloxamer-enhanced solubility of griseofulvin and its related antifungal activity against Trichophyton spp

Abstract Poorly water-soluble drugs, such as the antifungal drug griseofulvin (GF), exhibit limited bioavailability, despite their high membrane permeability. Several technological approaches have been proposed to enhance the water solubility and bioavailability of GF, including micellar solubilization. ...

Molecular structures and functional exploration of NDA family genes respond tolerant to alkaline stress in Gossypium hirsutum L

Biol. Res; 55 (), 2022
BACKGROUND: The internal NAD(P)H dehydrogenase (NDA) gene family was a member of the NAD(P)H dehydrogenase (ND) gene family, mainly involved in the non-phosphorylated respiratory pathways in mitochondria and played crucial roles in response to abiotic stress. METHODS: The whole genome identification, str...

Biomarcadores en las neoplasias mieloproliferativas clásicas BCR-ABL1 negativas
Biomarkers in Classical Myeloproliferative Neoplasms BCR-ABL1 negative

Introducción: Los biomarcadores son útiles en la definición del diagnóstico, pronóstico y seguimiento de múltiples enfermedades. La detección o medición de uno o más biomarcadores específicos representan alteraciones en vías genéticas o epigenéticas que controlan la proliferación, diferenci...

The potential of compounds isolated from Xylaria spp. as antifungal agents against anthracnose

Braz. j. microbiol; 49 (4), 2018
ABSTRACT Anthracnose is a crop disease usually caused by fungi in the genus Colletotrichum or Gloeosporium. These are considered one of the main pathogens, causing significant economic losses, such as in peppers and guarana. The current forms of control include the use of resistant cultivars, sanitary pr...

Synthesis, characterization and theoretical calculations of Cu(I) complex of trithiocyanuric acid [Cu(ttc)3]

Univ. sci; 23 (2), 2018
Abstract A new Cu(I) complex constructed by reaction of trithiocyanuric acid (ttc) and copper(II) perchlorate hexahydrate has been successfully synthesized by a slow sedimentation method in a DMF solvent at room temperature. The molecular structure of the compound was elucidated by MALDI-TOF MS, UV-Vis a...

Homology modeling and epitope prediction of Der f 33

Braz. j. med. biol. res; 51 (5), 2018
Dermatophagoides farinae (Der f), one of the main species of house dust mites, produces more than 30 allergens. A recently identified allergen belonging to the alpha-tubulin protein family, Der f 33, has not been characterized in detail. In this study, we used bioinformatics tools to construct the second...

Two novel Mg(II)-based and Zn(II)-based complexes: inhibiting growth of human liver cancer cells

Braz. j. med. biol. res; 51 (2), 2018
Two new Mg(II)-based and Zn(II)-based coordination polymers, {[Mg3(BTB)(DMA)4](DMA)2}n (1, H3BTB=1,3,5-benzenetrisbenzoic acid, DMA=N,N-dimethylacetamide) and {(H2NMe2)2[Zn3(BTB)2(OH)(Im)](DMF)9(MeOH)7}n (2, Im=imidazole, DMF=N,N-dimethylformamide), have been successfully synthesized and structurally cha...

Bases moleculares de la resistencia a meticilina en Staphylococcus aureus

Rev. chil. infectol; 35 (1), 2018
Resumen Desde el inicio de la era antimicrobiana se han ido seleccionando gradualmente cepas de Staphylococcus aureus resistentes a antimicrobianos de amplio uso clínico. Es así como en 1960 se describen en Inglaterra las primeras cepas resistentes a meticilina, y algunos años después son informadas ...

Asymmetric bioreduction of ketoesters derivatives by Kluyveromyces marxianus: influence of molecular structure on the conversion and enantiomeric excess

An. acad. bras. ciênc; 89 (3), 2017
ABSTRACT This study presents the bioreduction of six β-ketoesters by whole cells of Kluyveromyces marxianus and molecular investigation of a series of 13 β-ketoesters by hologram quantitative structure-activity relationship (HQSAR) in order to relate with conversion and enantiomeric excess of &...
