Design and synthesis of a new series of quinolinylaminoisoquinoline derivatives as conformationally restricted bioisosteres of Sorafenib are described. Their in vitro antiproliferative activity against A375P melanoma cell line was tested. Compounds 1b, 1d, 1g, and 1j showed the highest potency against A375P cell line with IC50 values in sub-micromolar scale. In addition, compound 1d exerted high selectivity towards RAF1 serine/threonine kinase with 96.47% inhibition at 10 µM, and IC50 of 0.96 µM. This compound can possess antiproliferative activity against melanoma cells through inhibition of RAF1 kinase.

the complexes display an intense emission peak of europium ion, which makes them a promising red color emitter in display devices. Internal quantum efficiency, color coordinates, Judd–Ofelt parameters, and energy transfer mechanism have been explored. The investigated antimicrobial and antioxidant activity suggest that the synthesized complexes are potent antimicrobial and antioxidant agents. Research
