Design, synthesis and molecular modelling of new thiazolidines 2,3-disubstituted with antitumoral activity
Résumé
New thiazolidine 2,3 disubstituted derivatives of 1'-acetamidyl-5'-nitroindazole with antitumoral activity against the Walker Carcinosarcoma and Jensen Sarcoma were designed and synthesized. The structural features of new compounds have been established by chemical elemental and spectral ( 1HNMR and IR) analyses. The optimized molecular geometry, the length of the covalent bonds, the atomic charges and some electro-optical parameters influencing the bioactivity of the new compounds were established by using HyperChem 5.0 programs. The determined values of the 1,3-thiazolidines toxicity are in the limits of the laboratory screening. The new compounds prove inhibition activity when they were tested on experimental tumors, the most active being 4-oxo-1,3-thiazolidine (VI) with ortho-hydroxy-phenyl.
