Abstract
El fármaco anticanceroso cis-diamino-(1,1-ciclobutanodicarboxilato)-trans-dihidroxiplatino (IV) o carboplatino-oxidado se sintetizó con 98% de pureza, oxidando el carboplatino Pt(II) con peróxido de hidrógeno al 30%. El análisis elemental fue confirmado por la compañía Atlantic Microlab, Inc. (Norcross-Georgia, USA). El estudio del comportamiento electroquímico del CBDCAOX interaccionando con bases nitrogenadas se realizó en un rango de -200 mV a -700 mV con un analizador voltamétrico modelo BAS 50W. El voltamograma de CBDCAOX libre mostró una señal de reducción en -625.4 mV y al interaccionar con timina la señal se desplazó hacia potenciales menos negativos. Este resultado indica la formación de un enlace fuerte en el complejo CBDCA-OX-timina.
The anticancer drug cis-diammine-(1,1-cyclobutanedicarboxylate)-trans-dihydroxyplatinum (IV) or carboplatin-oxidized was synthesized with 98% purity by oxidizing the carboplatin Pt (II) with hydrogen peroxide 30%. The elemental analysis was confirmed by Atlantic Microlab Inc. Company (Norcross-Georgia, USA). The study of the electrochemical behavior of CBDCAOX interacting with nitrogenous bases was performed in a range of -200 mV to -700 mV with a voltammetric analyzer BAS 50W model. The free CBDCAOX voltammogram showed a reduction signal in -625.4 mV and during the interaction with thymine the signal shifted to less negative potentials. This result indicates the formation of a strong bond in CBDCAOX-thymine complex.
