Abstract: | Tacrine derivatives containing iodobenzoic acid were developed as a novel multitarget-directed ligand and find potential application in the treatment of Alzheimer's disease. The aim of this study is to perform a physicochemical profile of this series. Experimental log P and pKa values were determined and compared with those already calculated. The results indicated better values of the tested compounds than the values predicted using computer software. The stability report was obtained using the developed HPLC method. The stability assay in different environment conditions provided information about the photosensitivity of these compounds and a proper method for the storage of this series of compounds. |
