A series of novel 2-imino-4-thiazolidinone derivatives 4a,b was synthesized through reaction of unsymmetrical thioureas 3a,b with chloroacetic acid. Condensation of 4a,b with aromatic aldehydes 5a-eyielded the corresponding 5-arylidene derivatives 6a-j. In addition, the reaction of 4a,b with 4-arylazo-3-hydroxybenzaldehydes 8a-c furnished the respective mono-arylazo-4-thiazolidinones10a-f. All the newly synthesized compounds were confirmed by their elemental analysis and spectral data. The antifungal activity of the newly synthesized compounds was assessed and the compounds 6d, 6e, 6i, 6j, 9a,b and 10a-frevealedhigher antifungal activity towards Alternaria solani than to the standard Ridomil gold plus. Moreover, the DNA toxicity of 4-thiazolidinone derivatives 6d, 9a, 10b, 10c and 10f on the nucleic acid of Alternaria solani (KT354939) was performed and the results showed qualitatively more than 70% cleavage. Also, compounds 6i, 6j, 9b, 10c and 10f were docked inside the active site of 1ZOYenzyme and suitable binding with the active site of amino acids, were displayed according to their bond lengths, angles and conformational energy.
