Dendrimers are well-defined, versatile polymeric architecture with properties resembling biomolecules. Dendritic polymers emerged as outstanding carrier in modern medicine system because of its derivatisable branched architecture and flexibility in modifying it in numerous ways. Dendritic scaffold has been found to be suitable carrier for a variety of drugs(More)
Inhalable clofazimine-containing dry powder microparticles (CFM-DPI) and native clofazimine (CFM) were evaluated for activity against Mycobacterium tuberculosis in human monocyte-derived macrophage cultures and in mice infected with a low-dose aerosol. Both formulations resulted in 99% killing at 2.5 μg/ml in vitro. In mice, 480 μg and 720 μg CFM-DPI(More)
Pyrazinamide (PZA) is an important first-line antituberculosis drug because of its sterilizing activity against semidormant tubercle bacilli. In spite of its very high in vivo activity, its in vitro activity is not apparent unless an acidic environment is available, which makes PZA susceptibility testing difficult by conventional methods. The present study(More)
Ligand-mediated targeting of drugs especially in anticancer drug delivery is an effective approach. Dendrimers, due to unique surface topologies, can be a choice in this context. In the present study, PAMAM (polyamidoamine) dendrimers up to fourth generation were synthesized and characterized through infrared (IR), nuclear magnetic resonance (NMR),(More)
The purpose of the present investigation was to evaluate the potential of surface engineered polypropylene imine (PPI) dendrimers as nanoscale drug delivery units for site-specific delivery of a model anti-cancer agent, doxorubicin.hydrochloride (DOX). Dextran conjugated PPI dendrimers were synthesized, characterized and further loaded with DOX. The(More)
The aim of the research work was to develop and characterize rifampicin (RIF) loaded gelatin nanoparticulate delivery system for the effective management of tuberculosis. Gelatin nanoparticles (GPs) containing RIF were prepared using two-step desolvation method. Formulations were characterized through transmission electron microscopy (TEM), atomic force(More)
The present investigation was aimed at exploring dendrimer-mediated solubilization and formulation development followed by in vitro, in vivo assessment of piroxicam (PXM) nanocomposite. For this, two dendrimer generations (3.0G and 4.0G) were synthesized and characterized by IR, (1)H NMR spectroscopic and electron microscopy techniques. The optimized(More)
Breast cancer is a menacing cancer, primarily affecting women. Continuous research is going on for detecting breast cancer in the early stage as the possibility of cure in early stages is bright. There are two main objectives of this current study, first establish statistics for breast cancer and second to find methodologies which can be helpful in the(More)
Animal models for testing different vaccine candidates have been developed since a long time for studying tuberculosis. Mice, guinea pigs and rabbits are animals most frequently used. Each model has its own merits for studying human tuberculosis, and none completely mimics the human disease. Different animal models are being used depending upon the(More)
It was Robert Koch who recognized the spectrum of pathology of tuberculosis (TB) in different animal species. The examination of clinical specimens from infected humans and animals confirmed the variable patterns of pathological reactions in different species. Guinea pigs are innately susceptible while humans, mice and rabbits show different level of(More)
