In the course of this paper, five novel hybrid compounds were synthesized and structurally characterized. Their structures consisted of anthranilic acid and its halogenated derivatives, along with 7-chloro-4-aminoquinoline. 1,3,4- oxadiazole, a five-membered heterocyclic ring resistant to chemical and enzymatic degradation, was used as a linker between the two pharmacophores. The synthesis began with the amidation of anthranilic acid methyl ester derivatives into their corresponding hydrazides (2a-e), in a reaction with an aqueous solution of hydrazine. Methyl ester derivatives 1a and 1b were previously obtained from the corresponding acid derivatives, using thionyl chloride and methanol, while the remaining ester derivatives were comercially available. The hydrazides were then converted to the corresponding 3-H-1,3,4- oxadiazol-2-one derivatives (3a-e) in a reaction with CDI. Another building block, the aminoquinoline derivative 4 was obtained in the reaction between 4,7-dichloroquinoline and ethylenediamine. 1,4-disubstituted semicarbazides 5a-e were obtained in the reaction between the aminoquinoline derivative 4 and the 3-H-1,3,4-oxadiazol-2-one derivatives 3a-e. During the final reaction step, a 1,3,4-oxadiazole ring was enclosed in a cyclization reaction and the final products 6a-e were obtained. The synthesized compounds were characterized using standard analytical and spectroscopic techniques: 1H and 13C NMR and MS. Their purity was determined by UPLC analysis, all of which exceeded 95 %. Melting points of the synthesized compounds were determined by differential scanning calorimetry. The calculation of the compounds' physicochemical descriptors, along with their pharmacokinetical parameters was performed using a free web tool called SwissADME. Based on the results, it can be concluded that the compounds show satisfactory properties in terms of solubility and permeability, which indicates high oral bioavailability. Biological screening of the synthesized compounds is beyond the scope of this paper, and will be performed in the future.
