In this study, a group of Schiff base derivatives and a group of formazan derivatives were prepared , reacted 2-amino-6-methoxy benzothiazole with 3-hydroxy-4-methoxy benzaldehyde to from the derivative of Schiff ,s Base then reactance the derivative of Schiff ,s Base NaN3 to from Tetrazole derivative (30) , as well as the reaction of the Schiff derivative 2-amino thiazole to from formazan derivative (31) , and the reaction of the Schiff derivative with 3-amino pyridine to from the formazan derivative (32) .
The concentration of poly aromatic hydrocarbons in three types of Phoenix Dactylifera L fruits (Iraqi, Iranian, Saudi) which are all collected from Iraq-Al-Diwaniyah city have been investigated. The PAHs levels in our samples were estimation by using Gas Chromatography Mass Spectroscopy (GC-MS). The technique of GC-MS was used for determination of ten of prior sixteen of carcinogenic PAHs compounds that are globally approved. The data indicated that thereare four PAHs in Iraqi dates, where fluorene was the highest level of these compounds with concentration of 124.509 μg/mL followed by Acenaphthylene, Naphththalene, andAnthracene with concentration about 16.227 μg/mL, 15.850 μg/mL, and 3.035 μg/mL respectively. While the Saudi dates found that there are five types of PAHs with different concentrations, where the highest concentration is for Naphththalene with concentration about 269.491 μg/mL followed by Acenaphthylene, Phenanthrene, Anthracene and Pyrene with levels of 23.670 μg/mL, 8.340 μg/mL, 1.761μg/mL and 0.543 μg/mL respectively.
Through this study, a group of heterocyclic compounds represented by a five-membered ring, seven rings, and a tetracyclic ring, represented by Oxazepine, β-lactam, Thiazolidines, and Imidazolidines, were prepared by depending on the intermediate compound, Schiff bases, that prepared from the reaction of a 2-Aminobenzimidazol with a 4-Bromobenzaldehyde to form (azomethine-CH=N) compound, the above compounds were formed by the pathway of this bond. All new derivatives were created by Fourier Transform Infrared Spectroscopy (FT-IR) Analysis, 1HNMR spectroscopic data, and the13C NMR spectrum. The biological activity of the prepared compounds and their effect on negative and positive bacteria (Escherichia coli) (Staphylococcus aureus) and Efficacy have been studied with Penicillium mushrooms.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
