AIMS   Present report describes the in vitro antimalarial activity and docking analysis of seven 4-aminoquinoline-clubbed 1,3,5-triazine derivatives on pf-DHFR-TS. METHODS AND RESULTS The antimalarial activity was evaluated in vitro against chloroquine-sensitive 3D7 strain of Plasmodium falciparum. Compounds were docked onto the active site of pf-DHFR-TS(More)
Plant growth promoting rhizobacteria (PGPR) are beneficial rhizobacteria which enhance plant growth as well as the productivity by a variety of mechanisms PGPR were isolated from the rhizosphere region of som plants (Machilus bombycina King) maintained at the Central Muga Eri Research and Training Institute, Lahdoigarh, Jorhat. A bacterial based(More)
Present communication deals with the docking study of hybrid phenyl thiazolyl-1,3,5-triazine analogues (1a-36d) on three selected different binding site viz., α, β and γ of wild type Pf-DFHR-TS. In admiration of excellent H-bond scoring, with regard to cycloguanil and to a large extent similar scoring with WR99210, compound 4a, 12b, 21c, 23c, 28d, 29d, 34d,(More)
BACKGROUND COPD may develop due to variation in the functioning of antioxidants along with smoking and environmental factors in genetically susceptible individuals. Since there are different views about the antioxidants responsible for detoxifying xenobiotic compound in the human body whose functional variation may lead to obstructive disease, this(More)
Malaria control is compromised worldwide by continuously evolving drug-resistant strains of the parasite demanding exploration of natural resources for developing newer antimalarials. The northeastern region of India is endemic for malaria characterized by high prevalence of drug-resistant Plasmodium falciparum strains. Many plants are used by the(More)
In the present study, we are reporting antimalarial potential of silver (AgNPs) and gold (AuNPs) nanoparticles synthesized by leaf and bark extract of Syzygium jambos (L.) Alston (Myrtaceae). AuNPs and AgNPs obtained by both the extracts were characterized using UV-vis spectroscopy, zeta potential, transmission electron microscopy (TEM), X-ray diffraction(More)
Mosquitoes are the vectors of several life threatening diseases like dengue, malaria, Japanese encephalitis and lymphatic filariasis, which are widely present in the north-eastern states of India. Investigations on five local plants of north-east India, selected on the basis of their use by indigenous communities as fish poison, were carried out to study(More)
PURPOSE To describe the microbiological profile and clinical outcome in the eyes with culture-proven exogenous endophthalmitis. METHODS A retrospective analysis of 495 eyes diagnosed as exogenous endophthalmitis was performed over a period of 10 years. In all, aseptically collected aqueous and vitreous aspirates were cultured for bacteria and fungus using(More)
A series of novel hybrid 4-aminoquinoline 1,3,5-triazine derivatives was synthesized in a five-steps reaction and evaluated for their in vitro antimalarial activity against chloroquine-sensitive (3D7) and chloroquine-resistant (RKL-2) strains of Plasmodium falciparum. Entire synthetic derivatives showed higher antimalarial activity on the sensitive strain(More)
To reduce the dependency on fresh AB+ serum in continuous culture of Plasmodium falciparum, a comparative study was undertaken to assess the in vitro adaptability of P. falciparum to media supplemented with fresh AB+ serum from whole blood, AB+ plasma, serum derived from AB+ plasma, AB+ human serum from Sigma, Albumax II, fetal bovine serum and new born(More)
