Onze alcalóides acridônicos isolados de Swinglea glutinosa (Bl.) Merr. foram avaliados para suas atividades in vitro contra linhagens de Plasmodium falciparum sensíveis a cloroquina 3D7, Trypanosoma brucei rhodesiense STIB9000 e Leishmania donovani L82. Ensaios com células KB foram também executados com o objetivo de se determinar o grau de toxicidade das substâncias ativas contra os parasitas....
In the ground electronic state, the first two (1 and 2) of the compounds investigated--9-(methoxyamino)acridine (1), 9-hydrazinoacridine (2), N-(2-chloroethyl)acridin-9-amine (3) and N-(5-methylpyridin-2-yl)acridin-9-amine (4)--exist principally in the imino tautomeric form, while the other two (3 and 4) can coexist as amino and imino tautomers in solvents of various polarities and abilities to...
Methyl-green-pyronin-Y staining was performed on 57 biopsies of Burkitt's tumour and 62 biopsies from other types of malignant lymphoma. The specificity of the pyronin staining for ribonucleic acid (RNA) was controlled by staining duplicate slides previously digested in ribonuclease. Burkitt's tumour cells have a higher cytoplasmic content of RNA than the cells of most other malignant lymphomas...
Fluorescent naphthoxazoles and their boron derivatives have been synthesized and applied as superior and selective probes for endocytic pathway tracking in live cancer cells. The best fluorophores were compared with the commercially available acridine orange (co-staining experiments), showing far better selectivity.
In this work, the acridine nucleus was used as a lead-compound for structural modification by adding different substituted thiosemicarbazide moieties. Eight new (Z)-2-(acridin-9-ylmethylene)-N-phenylhydrazinecarbothioamide derivatives (3a-h) were synthesized, their antiproliferative activities were evaluated, and DNA binding properties were performed with calf thymus DNA (ctDNA) by electronic a...
OBJECTIVE The purpose of the present study was to determine whether type III IFN can modulate the autophagic response in human osteosarcoma cell. METHODS Human osteosarcoma cell were treated with Interferon-λ1. We investigated that Interferon-λ1 could inhibit the invasive ability of osteosarcoma cells by Matrigel invasion assay. Autophagy were assessed by acridine orange staining, MDC stainin...
Background/Aim: The aim of this study was to evaluate the cytotoxic and apoptotic effects of chloroform extract (ASCH) from the seeds of Annona squamosa. Materials and Methods: MTT assay was employed to determine the cytotoxicity of the extract on A-549 and EAC cells and IC50 values were calculated. The apoptotic effects induced by the ASCH was evaluated by Acridine Orange Ethidium Bromide dual...
