Determination of the cytotoxic capacity of organotin compounds derivatives from salicylidene benzoylhidrazone por Berrones Reyes, Jessica Cecilia

“…Conclusions and contribution: In this research work, we reported four new tin compounds derivatives from bezoylhidrazones, which were characterized by spectroscopic and spectrometric techniques and X-ray diffraction In the same manner, cytotoxic ability of each compound was studied and reported and compared with metaled base drugs like cisplatin and carboplatin. Also, in some cases it was possible to use their luminescent ability to study their intracellular behavior.…”
