The synthesized compounds were evaluated for their antimicrobial activity against Gram-negative and Gram-positive bacterial strains, as well as Candida albicans. Molecular docking studies ,molecular dynamics simulations were conducted to determine the nature of the interactions with the enzymatic targets.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 19px;\">The results showed that the synthesized compounds possessed varying biological activities against the tested microorganisms. The molecular docking results indicated that several compounds were capable of binding to the enzymatic targets studied. Compounds RR7 and RR11 exhibited the highest binding values compared with the other synthesized compounds. The molecular dynamics simulation results indicated stable interactions between the compounds and some of the studied targets. These findings support the potential use of the synthesized compounds in further pharmaceutical studies.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 19px;\">The study recommended expanding the synthesis of new compounds from this series and modifying their chemical structures. It recommended conducting enzyme inhibition assays to verify their activity against the identified enzymatic targets, as well as cytotoxicity studies to evaluate the effects of the compounds on cells, in vivo toxicity studies were further recommended to determine safety levels and assess the potential for future development of these compounds.<\/span><\/p>\n<p>[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column]<div id=\"cz_60277\" class=\"cz_grid_p cz_60277\"><div class=\"cz_grid cz_grid_1 clr cz_grid_c3
