Preparation and characterization of Posaconazole as a Nano-micelles using d-α-Tocopheryl polyethylene glycol 1000 succinate (TPGS)
...Show More Authors

It is important to note that Posaconazole (POCZ) is a newly developed extended-spectrum triazole that belongs to BCS class II and has a solubility of less than 1µg/ml. In patients with a weakened immune system, POCZ has been shown to be effective as an antifungal treatment for invasive infections caused by candida and aspergillus species. The nano-micelles technique can be used to increase POCZ solubility. In order to increase their apparent solubility in water, nano-micelles are made by combining macromolecules that self-assemble into ordered structures capable of entrapping hydrophobic drug molecules in the interior domain. Dispersed colloidal systems, of which nano-micelles are a subset, are a large and diverse group. Composed of a phase that is itself dispersed throughout a medium (continuous phase). Surfactants form a colloidal solution when their concentration in solution is higher than their critical micelle concentration (CMC). POCZ nano-micelles are made with TPGS and tween 80. In this study, we prepared six different formulations and analyzed their particle size, polydispersity index (PDI), entrapment efficiency (EE), drug loadings (DL), saturation solubility, and in-vitro release. The drug-loaded nano-micelles of the Posaconazole formula (POCZ6) were characterized, and their properties were found to be: Particle size (90.68 nm), PDI (0.27), EE (94%), DL (10.3%), and best solubility factor (1133) are all better in the TPGS: tween80(1:5:3) ratio than in the pure drug. An in-vitro release study was conducted, and the results showed that the chosen formula POCZ6 released the entire dose of drug in 70 minutes, compared to only 23% for pure drug. Fourier transform infrared microscopy and other forms of investigation (FTIR). As can be seen from the data, there are no interactions or changes in the major peaks of Posaconazole when it is combined with polymer and surfactant.

Synthesis and Characterization of Nanocrystalline Zeolite Y
...Show More Authors

Worldwide attention is being focused on  nanocrystalline  zeolites  and they are replacing conventional ones due to their pronounced potential in many fields. In this study, NaY zeolite has been prepared hydrothermally using sol –gel method and modified to the proton type by ion –exchange process. Characterization is made using X-ray diffraction (XRD), thermogravimetric analysis (TGA),  Fourier transform infrared spectroscopy (FTIR),  Atomic force microscopy (AFM), Brunauer –Emmet- Teller (BET) nitrogen adsorption method, Ammonia Temperature programmed desorption (NH3-TPD) and Scanning electron microscopy( SEM).  The effect of aging time, silica to alumina ratio is studied and the results sh

Synthesis and characterization of new ligand c
...Show More Authors

In the present paper we report the synthesis of a new ligand [HL][(2-1-[(2-hydroxy-benzylidene)-hydrazono]-ethyl) benzene-1, 3, 5-triol and its complexes with (Mn", Fe", Cd", and Hg") The ligand was prepared in two steps. In the first step a solution of salicylaldehyed in methanol reacted under reflux with hydrazinemonohydrate to give an intermediate compound which reacted in the second step with 2, 4, 6-trihydroxidernonohydrate giving the tientioned ligand. The complexes were synthesis by direct reaction of the corresponding metal chloride with ligand. The ligand and the complexes have been characterized by spectroscopic methods [" H NMR, IR, UV-Vis,, atomic absorption], HPLC microanalysis along with conductivity measurements. From the abo
