The coordination capacity of thiosemicarbazone ligands and their synergism with palladium(II) ions modulate their reactivity, allowing custom design. Using thiosemicarbazones with two potential stable tautomeric forms and imidazole as bioisosteres, we studied how the substitution in the N4 group of the thiosemicarbazone by the p-chlorophenyl group modifies their hydrophilic properties, integrity in solution, and interactions toward their potential targets. The coordination to Pd(II) affects the bioactivity of the ligands, resulting in either improved or reduced antiproliferative effects depending on the cell type (cancerous versus bacterial, respectively).

Colorectal cancer (CRC) is the third most common cancer worldwide, and the second most common cause of cancer-related death. In 2020, the estimated number of deaths due to CRC was approximately 930000, accounting for 10% of all cancer deaths worldwide. Accordingly, there is a vast amount of ongoing research aiming to find new and improved treatment modalities for CRC that can potentially increase survival and decrease overall morbidity and mortality. Current management strategies for CRC include surgical procedures for resectable cases, and radiotherapy, chemotherapy, and immunotherapy, in addition to their combination, for non-resectable tumors. Despite these options, CRC remains incurable in 50% of cases. Nonetheless, significant improvements in research techniques have allowed for treatment approaches for CRC to be frequently updated, leading to the availability of new drugs and therapeutic strategies. This review summarizes the most recent therapeutic approaches for CRC, with special emphasis on new strategies that are currently being studied and have great potential to improve the prognosis and lifespan of patients with CRC.
