Abstract
Utility of waste in preparing new compounds and formulation with
anticipated biological activity
In this thesis, three main subjects were investigated:
1. Synthesis of some 1,3,4-oxadiazoles and 1,2,4-triazoles incorporating fatty acid
moieties. The starting materials of these syntheses are fatty acids obtained from
natural sources (e.g. the grease waste of the grilled chicken and mango seeds).
Some of the prepared compounds were evaluated as antitumor agents toward two
cell lines breast cell line MCF-7 and liver cell line HepG2. Also, the antimicrobial
activities were screened for gram positive bacteria, gram negative bacteria and
fungi strains.
2. 2-Furfuraldehyde extracted from lignocelluloses was used as starting material for
the synthesis of some acyclic and heterocyclic systems (e.g. chromene and
quinoline derivatives).
3. Some extracts were obtained from chicken feathers which disposal represents
environmental problem and black liquor. These extracts proved to be effective
larvicidal agents against Musca demostica larvae.
Keywords: 1,2,4-tiazole; 1,3,4-oxadiazole; anticancer; antimicrobial; chicken feather;
