Definitions
- the present invention relates to a pharmaceutical composition for treating Fms-like tyrosine kinase 3 (FLT3) mutation-positive cancer, a mutant FLT3 inhibitor, and their applications, which contain a nitrogen-containing heterocyclic compound or a salt thereof as an active ingredient.
- FLT3 Fms-like tyrosine kinase 3
- Fms-like tyrosine kinase 3 is a protein belonging to class III of receptor tyrosine kinases, and has five immunoglobulin-like-motifs in the N-terminal extracellular domain and two kinase-domains in the C-terminal. FLT3 is expressed on normal CD34-positive human bone marrow progenitor cells and dendritic progenitor cells, and plays an important role in the proliferation and differentiation of these cells (Non-patent Document 1).
- FLT3 ligand FL is expressed in bone marrow stromal cells and T cells, affects the cell development of many hematopoietic lineages, and interacts with other growth factors to cause stem cells, progenitor cells, dendritic cells. It is one of the cytokines that stimulate the growth of cells and natural killer cells.
- FLT3 dimerizes when FL binds and is activated by autophosphorylation. As a result, phosphorylation of AKT and ERK in the PI3 and RAS signaling pathways is triggered.
- FLT3 plays an important role in the proliferation and differentiation of hematopoietic cells. In normal bone marrow, FLT3 expression is restricted to early progenitor cells, but in blood cancer, FLT3 is expressed at a high concentration or FLT3 is mutated to activate the above signal transduction pathway. Contributes to cancer malignant growth.
- Examples of blood cancer include acute lymphocytic leukemia (ALL), acute myeloid leukemia (AML), acute promyelocytic leukemia (APL), chronic lymphocytic leukemia (CLL), and chronic myelogenous leukemia (CML).
- Chronic neutrophil leukemia CRL
- acute undifferentiated leukemia AUL
- undifferentiated large cell lymphoma ACL
- prolymphocytic leukemia PML
- juvenile myelomonocytic leukemia JMML
- adult T Examples include cell ALL, myelodysplastic syndrome (MDS), and myeloproliferative disease (MPD).
- Non-Patent Document 2 One of the causes of the recurrence / resistance is AML cell gene mutation, and FLT3 gene mutation has been confirmed most frequently.
- the FLT3 gene mutation includes an internal Tandem Duplication (ITD) mutation in which a part of the transmembrane region is repeated and an amino acid residue located at Tyrosine Kinase Domain (TKD) is different due to substitution, deletion or addition.
- ITD Tandem Duplication
- TKD Tyrosine Kinase Domain
- ITD mutation is known as a poor prognostic factor in AML, and it is a difficult situation although improvement of prognosis by existing chemotherapy is attempted. Under such circumstances, NCCN AML treatment guidelines stipulate that participation in clinical trials that can be considered should be considered as one of the treatment options.
- the WHO classification 4th edition is also described as one of gene mutations to be screened for AML diagnosis and treatment.
- the TKD mutation is known as a mutation or deletion of the 835th aspartic acid residue (D835) and its surrounding amino acid residues located in the Activation loop in AML, and is a poor prognostic factor. There is also a department report. Furthermore, TKD mutations include mutations in the 691 phenylalanine residue (F691) located in the gatekeeper region known as one of drug resistance mechanisms in other tyrosine kinases and the surrounding amino acid residues. Yes. In clinical trials aimed at treating AML with drugs that target FLT3, it has already been known that AML having both ITD mutation and TKD mutation is resistant to drugs.
- AC220 is a compound that selectively inhibits type III tyrosine kinases (FLT3, c-KIT, FMS, and PDGFR) and has been developed for AML (Patent Document 1). .

一般式[1]の化合物およびその塩は、FLT3変異陽性癌の処置のために有用である。
FLT3は、配列番号:1のアミノ酸配列(UniProt accession number: P36888)からなるポリペプチド、または配列番号:1のアミノ酸配列からなるポリペプチドと実質的に同一のポリペプチドである。また、FLT3は、受容体型チロシンキナーゼのクラスIIIに属するタンパク質であり、PI3K-AKTシグナル経路およびERK-MAPKシグナル経路を活性化し、細胞増殖、生存および分化に影響を及ぼす。FLT3は、N末端側細胞外領域の5つのimmnunoglobulin様領域、膜貫通領域、傍膜貫通領域、チロシンキナーゼ領域(TKD)およびC末端領域からなる。
本発明者らの知見によれば、一般式[1]で表される化合物は、配列番号:1のアミノ酸配列の第695番目のシステインとの特異的共有結合を介して、FLT3と結合する。
TKDのゲートキーパー領域の変異は、キナーゼ阻害剤に対する耐性化機構の原因の一つとして知られている。FLT3阻害剤の中にはゲートキーパー領域の変異により、ATP結合部位の構造変化が生じ、結合部位が狭くなるといった立体障害または変異部位のアミノ酸との分子間相互作用の消失などが起こり、FLT3活性阻害作用が大きく減弱されるものがある。
TKDのActivation loopは、通常はTKDのN末端側N lobeとC末端側C lobeの間に折りたたまれた構造を取り、基質結合部位やATP結合部位への基質やATPのアクセスを妨げる役割をしている(FLT3不活性体)。一方、Activation loopに位置するアミノ酸、特にD835またはY842に変異が起きると、Activation loopに大きな構造変化が起こり、ATP結合部位が開かれた構造となる(FLT3活性体)。FLT3不活性体のATP結合部位に、静電相互作用または水素結合などの分子間相互作用で結合するFLT3阻害剤の中には、D835またはY842の変異によるFLT3活性体に対して分子間相互作用を保つことができなくなり、結合力が低下して、FLT3活性阻害作用が減弱するものもある。
傍膜貫通領域においては、その領域内の様々な場所で、様々な長さのアミノ酸配列が繰り返されるアミノ酸の変異が生じうることが知られている。
アミノ酸配列に関し、同一性とは、特に記載した場合を除き、2つの配列を最適の態様で整列させた場合に、2つの配列間で共有する一致したアミノ酸の個数を考慮した百分率を意味する。アミノ酸配列の同一性に関する検索・解析は、当業者には周知のアルゴリズムまたはプログラム(例えば、BLASTPまたはClustalW)により行うことができる。プログラムを用いる場合のパラメーターは、当業者であれば適切に設定することができ、また各プログラムのデフォルトパラメーターを用いてもよい。これらの解析方法の具体的な手法もまた、当業者には周知である。
FLT3変異とは、FLT3のアミノ酸配列においてアミノ酸の変異があることを意味する。変異により、PI3K-AKTシグナル経路およびERK-MAPKシグナル経路に加え、STAT5シグナル経路またはその他の経路が活性化されうる。
アミノ酸の変異とは、アミノ酸配列中の1または複数個のアミノ酸の欠失、置換または付加を意味する。アミノ酸の変異は、欠失、置換または付加のいずれか一(例えば、置換)が1または複数個生じている場合と、欠失、置換および付加から選択される二以上が、それぞれ独立して1または複数個、組み合わされて生じている場合(例えば、1個の置換と3個の付加)とを含む。
なお「1または複数個のアミノ酸が欠失、置換または付加」というときの欠失、置換または付加されるアミノ酸の数および位置は、いずれの場合であっても、生じる変異体が意図した機能を有する限り、特に制限されない。欠失、置換または付加されるアミノ酸の数は、いずれの場合であっても、例えば、1~30個である。
アミノ酸の置換とは、アミノ酸配列中のアミノ酸残基の1つ以上が、異なる種類のアミノ酸残基の1つ以上に変えられた変異を意味する。
アミノ酸の付加とは、アミノ酸配列中にアミノ酸残基の1つ以上が付加された変異を意味し、付加には、アミノ酸配列の端にアミノ酸残基が付加されたものおよびアミノ酸配列の途中にアミノ酸残基を付加されたものが含まれる。

ある癌がFLT3変異陽性であるとは、その癌細胞のFLT3のアミノ酸配列において変異があることを意味する。また、FLT3変異陽性とは、そのような変異のあるアミノ酸配列をコードするように、FLT3遺伝子に変異があることも意味する。FLT3のアミノ酸配列に変異がある場合、FLT3遺伝子に変異があることは明らかである。
一般式[1]の化合物およびその塩は、FLT3変異陽性であるこれらの癌に対して用いることができる。
一般式[1]の化合物またはその塩は、変異型FLT3阻害剤の有効成分として用いることができる。好ましくは、TKD変異を含む変異型FLT3を阻害する剤として用いることができる。このような剤はまた、野生型FLT3を阻害するものであってもよい。一般式[1]の化合物またはその塩を有効成分とする変異型FLT3阻害剤は特に、抗癌剤として有用である。
