Zn(II) Based Potential Drug Containing Sertraline as a Strong Antidepressant Agent

A novel compound for depression treatment and other psychiatric disorders has been obtained being capable of displaying the combined benefits of sertraline and an essential element such as zinc in order to get better antidepressant and negative side effects. Our working group has synthesized a salt formulation (SerH2 ) 2 +[ZnCl4 ] 2- (C34H36N2 Cl8 Zn, sertralonium tetrachlorozincate(II)). The crystal structure was determined by X-ray diffraction methods. It crystallizes in the monoclinic P21 space group with a=7.3869(2) Å, b=13.2888(4) Å, c=19.3541(6) Å, β=96.596(3)° Å, β=91.792(4)°, and Z=2 molecules per unit cell. Their antidepressant activity in the forced swimming test (FST) proved to be stronger than the one shown by the commercial drug sertraline hydrochloride per se. Furthermore, this compound suppressed the anorexigenic effect caused by the antidepressant and showed an improvement in the assimilation time during in vitro fluorescence studies with bovine serum albumin. The results of this work have led to a patent application which was filed (Nº 20150103320) in Argentine country.Centro de Química InorgánicaFacultad de Ciencias ExactasInstituto de Física La Plat

Evidence of promising biological-pharmacological activities of the sertraline-based copper complex: (SerH<SUB>2</SUB>)<SUB>2</SUB>[CuCl<SUB>4</SUB>]

In the current study the ability of copper complex to exert multiple biological activities is combined with the pharmacological action of sertraline (SerH2Cl, antidepressant drug). The hydrated and anhydrous forms of the tetrachlorocuprate(II) salts, namely (SerH2)2[CuCl4]·½H2O and (SerH2)2[CuCl4], were synthesized and characterized by physicochemical methods. The crystal structures were determined by X-ray diffraction methods. The hydrate complex crystallizes in the monoclinic P21 space group with a =8.0807(2) Å, b =36.2781(8) Å, c =12.6576(3) Å, β =95.665(2)°, and Z =4 molecules per unit cell and the un-hydrate in P21 with a =13.8727(6) Å, b =7.5090(3) Å, c= 18.618(1) Å, β =104.563(6)°, and Z =2. It has been suggested that Cu(II) ions might be critical in the development of mood disorders, showed potent biocidal activity, and also acted as analgesic adjuvant. To improve sertraline efficiency, the antidepressant and analgesic activities of the complex have been assessed in rats denoting a marked synergistic effect. Antithyroid and antimicrobial activities were also evaluated. Because depressive disorders and hyperthyroidism diseases led to an oxidative stress state, antioxidant capability has also been tested. The complex behaved as a good superoxide radical scavenger (IC50=6.3 × 10−6 M). The ability of the complex to act as bromoperoxidase mimic was assessed. A pseudofirst order constant of k = 0.157 ± 0.007 min−1 has been determined. The complex evidences promising biological-pharmacological activities and the albumin binding studies showed a Kb of 2.90 ×103 M−1 showing an improvement in the uptake of sertraline by albumin at 8 h incubation (time required for effective interaction of sertraline with the protein).Centro de Química InorgánicaInstituto de Física La Plat

Aprendizajes y prácticas educativas en las actuales condiciones de época: COVID-19

“Esta obra colectiva es el resultado de una convocatoria a docentes, investigadores y profesionales del campo pedagógico a visibilizar procesos investigativos y prácticas educativas situadas en el marco de COVI-19. La misma se inscribe en el trabajo llevado a cabo por el equipo de Investigación responsable del Proyecto “Sentidos y significados acerca de aprender en las actuales condiciones de época: un estudio con docentes y estudiantes de la educación secundarias en la ciudad de Córdoba” de la Facultad de Filosofía y Humanidades. Universidad Nacional de Córdoba. El momento excepcional que estamos atravesando, pero que también nos atraviesa, ha modificado la percepción temporal a punto tal que habitamos un tiempo acelerado y angustiante que nos exige la producción de conocimiento provisorio. La presente publicación surge como un espacio para detenernos a documentar lo que nos acontece y, a su vez, como oportunidad para atesorar y resguardar las experiencias educativas que hemos construido, inventado y reinventando en este contexto. En ella encontrarán pluralidad de voces acerca de enseñar y aprender durante la pandemia. Este texto es una pausa para reflexionar sobre el hacer y las prácticas educativas por venir”.Fil: Beltramino, Lucia (comp.). Universidad Nacional de Córdoba. Facultad de Filosofía y Humanidades.
