3. SÍNTESE DE 1,7-FENANTROLINAS E 7-AMINOQUINOLINAS TRIFLUORMETIL SUBSTITUÍDAS / SYNTHESIS OF TRIFLUOROMETHYL SUBSTITUTED 1,7-PHENANTHROLINES AND 7-AMINOQUINOLINES
This work, at first, describes the synthesis and characterization of new series of (Z,Z)-N,N-bis(oxotrifluoroalkenyl)-1,3-phenylenediamines by the addition/elimination reaction of β-alkoxyvinyl trifluoromethyl ketones with 1,3-phenylenediamine, in 47-91 % yields. The 4-alkyl[aryl(heteroaryl)]-4-alkoxy-1,1,1-trifluoro-3-alken-2-ones, of general formula F

4. ATIVIDADE LEISHMANICIDA DE DERIVADOS AMINOQUINOLINICOS E EFEITO IMUNOMODULATÓRIO EM MACRÓFAGOS PERITONEAIS INFECTADOS COM LEISHMANIA AMAZONENSIS E L. MAJOR
The leishmaniasis are parasitic-infection diseases that affect 12 million people in 88 countries, it remains a serious public health problem worldwide, including in Brazil. This disease is caused by different Leishmania species, which invade and multiply within macrophages in vertebrate host. No vaccine exists yet and chemotherapy has been based mainly in pe

5. Síntese e Avaliação Biológica de Derivados Cíclicos de Tiopurina e de Derivados de Quinolinas Conjugados com Ácido Cólico Via Click Chemistry
This dissertation entitled Synthesis and Biological Evaluation of Cyclical Derivatives of Thiopurine and Quinolines Derivatives Conjugated with Cholic Acid via Click Chemistry was divided in two chapters that describe the synthesis of compounds with potential anti-parasitic activity. The first chapter describes the synthesis of 6-mercaptopurine (6-MP) deriva

6. Susceptibility of Colombian Plasmodium falciparum isolates to 4-aminoquinolines and the definition of amodiaquine resistance in vitro
There are wide variations in the threshold used to define in vitro resistance of Plasmodium falciparum to amodiaquine (AQ), probably due to differences in methodology and interpretation. In vitro susceptibility data of Colombian P. falciparum strains to AQ and N-desethylamodiaquine is used to illustrate the need to standardized methodologies and compare inhi

7. 8-Aminoquinolines Active against Blood Stage Plasmodium falciparum In Vitro Inhibit Hematin Polymerization
From the Walter Reed Army Institute of Research (WRAIR) inventory, thirteen 8-aminoquinoline analogs of primaquine were selected for screening against a panel of seven Plasmodium falciparum clones and isolates. Six of the 13 8-aminoquinolines had average 50% inhibitory concentrations between 50 and 100 nM against these P. falciparum clones and were thus an o

8. Activities of Various 4-Aminoquinolines Against Infections with Chloroquine-Resistant Strains of Plasmodium falciparum1
The studies reported here stemmed from a personal report by Geiman on the capacity of the 4-aminoquinoline amodiaquin to inhibit in vitro maturation of ring stages of the chloroquine-resistant Monterey strain of Plasmodium falciparum. This observation, confirmed in owl monkeys infected with this strain, led to a comparison of the activities of chloroquine, a

9. 8-Aminoquinolines from Walter Reed Army Institute for Research for treatment and prophylaxis of Pneumocystis pneumonia in rat models.
Three 8-aminoquinolines from the Walter Reed Army Institute for Research (WRAIR), WR6026, WR238605, and WR242511, strongly inhibited Pneumocystis carinii growth in vitro at 1 microgram/ml. This activity was similar to that of primaquine. In rat therapy models, the WRAIR compounds affected Pneumocystis pneumonia at doses as low as 0.25 mg/kg (WR242511) or 0.5

12. Central Role of Hemoglobin Degradation in Mechanisms of Action of 4-Aminoquinolines, Quinoline Methanols, and Phenanthrene Methanols
We have used a specific inhibitor of the malarial aspartic proteinase plasmepsin I and a nonspecific cysteine proteinase inhibitor to investigate the importance of hemoglobin degradation in the mechanism of action of chloroquine, amodiaquine, quinine, mefloquine (MQ), halofantrine, and primaquine. Both proteinase inhibitors antagonized the antiparasitic acti
