Síntesis y actividad antiproliferativa de una mezcla de derivados de (+ / -) 7-cloro-(4-tioalquilquinolina). Inducción de apoptosis y daño sobre el ADN/ARN.

After cardiovascular diseases, cancer, a non-communicable pathology, has been considered the second cause of death each year globally and as the most important barrier to increasing life expectancy in the 21st century. Advances of great relevance have been made in its prevention and treatment, however, there is still a long way to go to achieve an eff ective treatment for each type of cancer. This paper describes approaches to reposition and synthesis of hybrid molecules with potential antineoplastic activity. To obtain the key intermediate aldehyde, the Dess-Martin oxidation methodology was used, which was coupled with the corresponding ketones using LDA. The fi nal hybrid compounds were obtained as a racemic mixture. The in vitro antiproliferative activity of the fi nal compounds was evaluated against eight cell lines derived from human solid tumors, and four non-cancerous cell lines. The compound 11d turned out to be the most eff ective and with the highest safety index. The results suggested that these compounds could block the cell cycle and induce apoptosis and death in CCRF-CEM cells in a dose-dependent manner in vitro. [ABSTRACT FROM AUTHOR]
