Consequently, regarding the control percentage (%Ctrl) representing the lysed kinases indicating lower percentage values associated with efficient binding with compound 21 against c-Kit, PDGFRẞ, and FLT3 with percentage values of 0, 0.05, 2.8%, respectively, therefore compound 21 could be utilized to combat different cancer kinds by lessening as possible resistance versus them. This evidence concerns the gene FLT3 and cancer.
