A series of sulfanilamide Schiff basederivatives (1 to 15) have been designed as potential antitubulin agents depending on the chemical structures of combretastatine A-4 and isoquinoline sulfamate (antimitotic agents under investigation). The designed compounds were synthesized by microwave chemical synthesis, their purity was confirmed by melting point and HPLC and chemical structures were determined
Novel sulfa Schiff bases were synthesized and characterized by a reaction between aromatic sulfonamides and
aromatic aldehydes or heterocyclic ketones in equimolar ratios. Their cytotoxicity was evaluated by the resazurin assay
towards human sensitive CCRF-CEM and multidrug-resistant CEM/ADR5000 leukemia cells. Three of the tested
compounds viz., 4-(anthracen-9-ylmethyleneamino)-N-(pyrimidin-2-yl)benzenesulfonamide (4), 4-(anthracen-9-
ylmethyleneamino)benzenesulfonamide, (5) and 4-((3-phenylallylidene)amino)benzene-sulfonamide, (6) were cytotoxic
(IC50 values: 5.38-19.96 µM). CEM/ADR5000 cells were not cross-resistant to these compounds, indicating activity
against otherwise drug-resistant tumors. Compound 6 inhibited P-glycoprotein by increasing doxorubicin accumulation
and reducing expression of P-glycoprotein in CEM/ADR5000 cells. A human P-glycoprotein homology model was used
for molecular docking studies. Compound 6 and verapamil (a well-known P-glycoprotein inhibitor) docked with similar
binding energies to the same binding pocket.

A series of N-cinnamyl phenylacetamides (1-8) and N-(3,7-dimethylocta-2,6-dien-1-yl) phenylacetamide derivatives (9-12) with different active moieties have been designed, synthesized and tested for antioxidant and antimicrobial activity. The synthetic protocol was based on the formation of Schiff bases followed by chloroacetylation of imines. The chemical structures of the compounds were recognized
