1. PREPARAÇÃO DE HIDRAZONA E N-ACILIDRAZONA USANDO FÁRMACOS COMERCIAIS COMO REAGENTES: AULAS PRÁTICAS DE SÍNTESE DE COMPOSTOS BIOATIVOS
Several scientific works demonstrate the chemical and medicinal importance of hydrazone compounds. In this regard, the present paper proposes some practical classes of chemoinformatics and organic chemistry, using investigative and illustrative strategies, to teach the synthesis of a hydrazone and a N-acylhydrazone with proven biological activity. The motiva

2. SÍNTESE, ATIVIDADE ANTILESHMANIA E CITOTÓXICA DE HIDRAZONAS DERIVADAS DE ALDEÍDOS NATURAIS
Leishmaniasis is endemic anthropozoonosis considered to be a severe public health problem. The treatment with pentavalent antimonials presents high toxicity motivating the search for effective and less toxic drugs. Hydrazones and N-acylhydrazones are functional groups that are prominent in Medicinal Chemistry, including as antiprotozoals. In this context, fi

3. Antimicrobial activity and acetylcholinesterase inhibition by extracts from chromatin modulated fungi
ABSTRACT Major health challenges as the increasing number of cases of infections by antibiotic multiresistant microorganisms and cases of Alzheimer's disease have led to searching new control drugs. The present study aims to verify a new way of obtaining bioactive extracts from filamentous fungi with potential antimicrobial and acetylcholinesterase inhibitor

4. Anti-TNF-α and hydralazine drug-induced lupus
AbstractDrug-induced lupus is a rare drug reaction featuring the same symptoms as idiopathic lupus erythematosus. Recently, with the introduction of new medicines in clinical practice, an increase in the number of illness-triggering implicated drugs has been reported, with special emphasis on anti-TNF-α drugs. In the up-to-date list, almost one hundred medi

5. Floating tablets of hydralazine hydrochloride: optimization and evaluation
O cloridrato de hidralazina apresenta meia-vida de 2 a 4 horas, com biodisponibilidade oral de 26-50%. Uma vez que a hidralazina possui efeito desmetilante em vários genes supressores, ela pode ser utilizada para diversos tipos de câncer, em apoio à quimioterapia. O objetivo deste estudo foi o de avaliar e otimizar comprimidos flutuantes de cloridrato de

6. Use of chromatin modifying agents in bovine somatic cell nuclear transfer / Uso de agentes modificadores de cromatina na transferência nuclear de células somáticas em bovinos
Embora a transferência nuclear de células somáticas (TNCS) seja uma ferramenta promissora, seu amplo uso é impedido devido às altas taxas de mortalidade durante o desenvolvimento dos animais clonados. Acredita-se que a reprogramação epigenética anormal seja a principal causa desta baixa eficiência. Nós hipotetizamos que agentes modificadores de cro

7. INTERFERÊNCIA DE VASODILATADORES NA HIDRÓLISE DE NUCLEOTÍDEOS DA ADENINA EM PLAQUETAS DE PACIENTES HIPERTENSOS / INTERFERENCE OF VASODILATORS IN THE HYDROLYSIS OF ADENINE NUCLEOTIDE ON PLATELETS OF HYPERTENSIVE PATIENTS
The thrombogenic process that affects the hypertensive patient is associated with regulatory mechanisms present in the vascular endothelium. These mechanisms involve the release of a endothelium-derived relaxing factor, ectonucleotidases and calcium ions. Considering that vasodilators act both on blood pressure and on homeostasis, we evaluated the interferen

8. Early renal abnormalities in a experimental model that combind genetic arterial hypertension and diabetes mellitus : effect of anty-hypertensive treatment / Alterações renais precoces em um modelo experimental que combina hipertensão arterial genetica e diabetes mellitus : efeitos do tratamento anti-hipertensivo
In diabetic patients hypertension is the main secondary factor associated with the development and progression of renal disease. However, the mechanism of interaction between diabetes and hypertension to exacerbate diabetic renal disease is poorly understood. The aim of this study was to evaluate the effect of presence of hypertension had on nephrin expressi

9. A prevenção da hipertensão arterial determina a redução da lesão renal no diabetes experimental
The aim of this study was to evaluate the effect of preventing hypertension with drugs that block the renin-angiotensin system or conventional therapy on diabetic nephropathy in a model of genetic hypertension and diabetes. Four-week-old spontaneously hypertensive rats (SHR) streptozotocin-induced diabetes were randomized for no treatment, or for treatment w

10. Do cardiologists at a university hospital adopt the guidelines for the treatment of heart failure?
OBJECTIVE: To verify whether the guidelines for the treatment of heart failure have been adopted at a university hospital. The guidelines recommend the following: use of angiotensin-converting enzyme inhibitors for all patients with systolic ventricular dysfunction, use of digitalis and diuretics for symptomatic patients, use of beta-blockers for patients in

11. Induction of antibodies to nuclear antigens in rabbits by immunization with hydralazine-human serum albumin conjugates.
The antihypertensive drug hydralazine can induce in man a syndrome similar to spontaneous systemic lupus erythematosus (SLE). The pathogenesis of this drug-induced syndrome is not understood. In this investigation, five groups of rabbits were studied: group I, 10 rabbits hyperimmunized with hydralazine conjugated to human serum albumin (HSA) in complete Freu

12. Effects of captopril and a combination of hydralazine and isosorbide dinitrate on myocardial sympathetic tone in patients with severe congestive heart failure.
Changes in circulating catecholamines and transmyocardial catecholamine balance associated with improved left ventricular function were studied in patients with chronic heart failure after treatment with captopril (10 patients) and hydralazine in combination with isosorbide dinitrate (eight patients). Cardiac performance improved in response to both captopri
