摘要:Epidermal Growth Factor Receptor (Egfr) Amplification Has Been Demonstrated To Be Critical For The Inherent And/or Acquired Resistance Against Current B-Raf(V600E) Inhibitor Therapy For Melanoma And Colorectal Cancer Patients. We Describe The Discovery And Structure-Activity Relationship Study Of A Series Of 1H-Pyrazolo[3,4-B]Pyridine-5-Carboxamide Analogues As Novel Dual Inhibitors Of Egfr And B-Raf(V600E) Mutant. One Of The Most Promising Compounds,6A,Potently Inhibited Both Of The Kinases With Ic50 Values Of 8.0 And 51 Nm,Respectively. The Compound Also Strongly Suppressed The Proliferation Of A Panel Of Intrinsic And Acquired Resistant Melanoma And/or Colorectal Cancer Cells Harboring Overexpressed Egfr With Submicromolar Ic50 Values. Further Mechanism Investigation Revealed That 6A Could Sustainably Inhibit The Activation Of The Mapk Path Way In The Resistant Sk-Mel-28 Pr30 Melanoma Cancer Cells And Widr Colorectal Cancer Cells With Egfr Amplification. Our Results Support The Hypothesis That The Egfr/b-Raf(V600E) Dual Inhibition Might Be A Tractable Strategy To Overcome The Intrinsic And Acquired Resistance Of Melanoma And/or Colorectal Cancers Against The Current B-Raf(V600E) Inhibitor Therapy.
