The objective of this study was to prepare and characterize complexes of 2-(2-nitrovinyl) furan (G-0) with 2-hydroxypropyl-β-cyclodextrin (HP-β-CD) and sulfobutyl ether-β-cyclodextrin (SBE-β-CD). The solid inclusion complexes were prepared using kneading and freeze-drying methods. Phase solubility profiles were used to obtain the apparent stability(More)
A high performance liquid chromatography (HPLC) method for the qualitative and quantitative determination of amonafide (CAS 69408-81-7) and mitonafide (CAS 54824-17-8), two new antineoplastic molecules, in finished pharmaceutical dosage forms (tablets) is developed and validated. The results submitted in this work suggest that HPLC method is linear (range(More)
In the present work, the sublimation of crystalline solid 2-(2-nitrovinyl) furan (G-0) in the temperature range of 35 to 60 °C (below the melting point of the drug) was studied using thermogravimetric analysis (TGA). The sublimated product was characterized using Fourier-transformed-infrared spectroscopy (FT-IR) and thin layer chromatography (TLC). The(More)
The validation of an analytical method for the quantitative determination of erythromycin thiocyanate formulated in an antibiotic preparation for veterinary use was carried out. This method is based on the microbiological method described in the European Pharmacopoeia to analyze erythromycin thiocyanate as a raw material. This erythromycin thiocyanate(More)
