A Promising Paradigm Shift in Cancer Treatment with FGFR Inhibitors.

FGFR have been demonstrated to perform a crucial role in biological processes but their overexpression has been perceived as the operator component in the occurrence and progression of different types of carcinoma. Out of all the interest around cancer, FGFR inhibitors have assembled pace over the past few years. Therefore, FGFR inhibitors are one of the main fundamental tools to reverse drug resistance, tumor growth, and angiogenesis. Currently, many FGFR inhibitors are under the development stage or have been developed. Due to great demand and hotspots, different pharmacophores were approached to access structurally diverse FGFR inhibitors. Here, we have selected to present several representative examples such as Naphthyl, Pyrimidine, Pyridazine, Indole, and Quinoline derivatives that illustrate the diversity and advances of FGFR inhibitors in medicinal chemistry. This review focuses on the SAR study of FGFR inhibitors last five years which will be a great future scope that influences the medicinal chemist to work towards more achievements in this area.
