Thermodynamic, spectral and antimicrobial activity of inclusion complexes of acridone and its oxime with β-cyclodextrin
One of the methods to enhance bio-accessibility of drugs like Acridone and its oxime is toform inclusion complexes with β-cyclodextrin. The formation of such complexes has beenconfirmed by changes in spectral characteristics and melting point data. The aqueous phasesolubility studies reveal 1:1 stoichiometry between the compound and, β-cyclodextrin. The studyof thermodynamic parameters like ΔG,...
متن کاملStudies on inclusion complexes of 2-[Substituted arylideamino]-1, 3, 4-thiadiazino [6,5b]indole with β- Cyclodextrin
Inclusion complexes of 2-[Arylidenamino]-1,3,4-thiadiazino[6,5b]indoles have been prepared with β-cyclodextrin so as to increase the solubility of these compounds in polar medium which may increase theirbioaccessibility. The formation of inclusion complexes is known from the study of changes in physical andspectral properties of the compounds. The stability of the inclusion complexes has been s...
متن کاملRemoval of Reactive Dyes from Wastewater using Cyclodextrin Functionalized Polyacrylonitrile Nanofibrous Membranes
Electrospinning of nanofibers with cyclodextrin (CD) is attractive because the produced fibers can potentially increase the efficiency of nanofibrous membranes by facilitating the complex formation with organic compounds and high surface area of the nanofibers. In this work, polyacrylonitrile (PAN) nanofibers functionalized with β– cyclodextrin (βCD) during an electrospinning process were used ...
متن کاملFormation of Inclusion Complexes of Cycldextrin with Ethanol under Anhydrous Conditions.
Complex formation of poorly water soluble organic compounds with cyclodextrin (CD) is quite difficult in an aqueous cyclodextrin system. Formation of the inclusion complex of d-limonene, phenyl ethanol, acetophenone, or menthol was investigated in a slurry form of α-, β-, or γ-CD in organic solvents or alcohol under anhydrous conditions. Ethanol and methanol were found to be good solvents for t...
متن کاملFormulation and In-vitro Evaluation of Orally Disintegrating Tablets of Olanzapine-2-Hydroxypropyl-β-Cyclodextrin Inclusion Complex
The aim of this study was to design orally disintegrating tablets of Olanzapine and to complex Olanzapine with 2-hydroxypropyl-β- cyclodextrin with special emphasis on disintegration and dissolution studies. Phase solubility studies demonstrated the formation of 1:1 molar inclusion complex by kneading method. Tablets were prepared by using superdisintegrants namely, sodium starch glycolate, cro...
