FMS-like tyrosine kinase 3 inhibitors: a patent review

Abstract

Areas covered: This paper provides a comprehensive review of the Flt3 inhibitor patents currently available. Information from original research articles in peer-reviewed journals and current clinical developments from several resources is also described. Expert opinion: Our understanding of Flt3 inhibitors has been increased by findings from recent preclinical and clinical trials. Some Flt3 inhibitors show good efficacy in AML patients, but relapse and resistance to these inhibitors are still unavoidable. To address these problems, structurally diverse inhibitors, which exhibit inhibitory activities against both wild type and mutated Flt3, should be explored.
