Antecedentes da InvençãoBackground of the Invention

Diferentes vias de sinalização celular estão associadas à evolução, agressividade e potencial de metástase de tumores malignos/Esta diversidade de mecanismos resulta em heterogeneidade, redundância e na possibilidade de o tumor driblar o bloqueio de apenas uma via de sinalização, resultando em 20 resistência primária ou adquirida. [Tabernero, J., Mol. Cancer Res., 2007, 5, 203] Deste modo, a natureza multifatorial do câncer determina a necessidade de abordagens terapêuticas múltiplas ou multifuncionais, e.g. um único composto capaz de modular diferentes vias de sinalização envolvidas na patologia da doença. [Antonello, A. et al., J. Med. Chem., 2006, 49, 6642]Different cellular signaling pathways are associated with the evolution, aggressiveness and metastasis potential of malignant tumors / This diversity of mechanisms results in heterogeneity, redundancy and the possibility of the tumor circumventing the blockage of only one signaling pathway, resulting in 20 primary or secondary resistance. acquired. [Tabernero, J., Mol. Cancer Res., 2007, 5, 203] Thus, the multifactorial nature of cancer determines the need for multiple or multifunctional therapeutic approaches, eg a single compound capable of modulating different signaling pathways involved in the pathology. of the disease. [Antonello, A. et al., J. Med. Chem., 2006, 49, 6642]

As proteínas cinases exercem papel de destaque na regulação deProtein kinases play a prominent role in the regulation of

diversos processos celulares, incluindo a proliferação, diferenciação e sobrevivência da célula. [Ishikawa, T. et ai, J. Med. Chem., 2011, 54, 8030]various cellular processes, including cell proliferation, differentiation and survival. [Ishikawa, T. et al., J. Med. Chem., 2011, 54, 8030]

Diversos membros da família das proteínas cinases já foram identificados até o momento. Estas enzimas catalisam a reação de fosforilação de diferentes substratos, desempenhando funções primordiais em praticamente todas as etapas da vida celular. Considerando-se que cerca de 1/3 das proteínas conhecidas em mamíferos contém fosfato ligado covalentemente, qualquer alteração no funcionamento dessas proteínas pode gerar respostas celulares inadequadas, contribuindo para o desenvolvimento de patologias tais como diabetes, câncer, artrite reumatóide, entre outras [Cohen, P., J. Biol.Several members of the protein kinases family have been identified so far. These enzymes catalyze the phosphorylation reaction of different substrates, performing primary functions at virtually every stage of cell life. Considering that about 1/3 of known mammalian proteins contain covalently bound phosphate, any alteration in the functioning of these proteins can generate inadequate cellular responses, contributing to the development of conditions such as diabetes, cancer, rheumatoid arthritis, and others [Cohen , P., J. Biol.

Chem., 1999, 3, 459].Chem. 1999, 3, 459].

Particularmente, o receptor do fator de crescimento epidérmico (do inglês, epidermal growth factor receptor - EGFR, também conhecido como ErbBI, HER1) é um tirosina cinase receptora transmembrânica que pertence àParticularly, the epidermal growth factor receptor (EGFR), also known as ErbBI, HER1) is a transmembrane receptor tyrosine kinase belonging to the

família de receptores ErbB [Chilin, A. et ai, J. Med. Chem., 2010, 53, 1862]] i.e.ErbB receptor family [Chilin, A. et al., J. Med. Chem., 2010, 53, 1862]] i.e.

um^'família de quatro membros de tirosinas cinases receptoras de fatores de crescimento que inclui o EGFR (HER1), ErbB2 (HER2/neu), ErbB3 (HER3), e ErbB4 (HER4) [Antonello, A. et al., J. Med. Chem., 2006, 49, 6642], A ligação de fatores de crescimento específicos ao domínio extracelular dos receptores ErbB promove dimerização e autofosforilação, ativando os domínios tirosina 15 cinase citoplasmáticos e conduzindo à ativação de vias de sinalização que regulam a diferenciação celular, crescimento celular, diferenciação, migração e apoptose. [Chilin, A. et al., J. Med. Chem., 2010, 53, 1862]a four-member family of growth factor receptor tyrosine kinases that includes EGFR (HER1), ErbB2 (HER2 / neu), ErbB3 (HER3), and ErbB4 (HER4) [Antonello, A. et al., J Med. Chem., 2006, 49, 6642], The binding of specific growth factors to the extracellular domain of ErbB receptors promotes dimerization and autophosphorylation, activating cytoplasmic tyrosine 15 kinase domains and leading to activation of signaling pathways that regulate differentiation. cell growth, cell growth, differentiation, migration and apoptosis. [Chilin, A. et al., J. Med. Chem., 2010, 53, 1862]

Vias de sinalização celular mediadas pelo EGFR têm sido implicadas em vários tumores malignos humanos, promovendo crescimento-do tumor, invasão 20 de tecidos e órgãos, angiogênese e metástase. Superexpressão e/ou desregulação do EGFR são achados clínicos comuns em tumores sólidos e estão geralmente associadas a um prognóstico desfavorável. [Antonello, A. et al., J. Med. Chem., 2006, 49, 6642] A ativação do EGFR também estimula a liberação do fator de crescimento do endotélio vascular (do ingles, vascular 25 endothelial growth factor - VEGF), considerado o indutor primário do processo de angiogênese. [Arora, A. & Scholar E., J. Pharmacol. Exp. Ther., 2005, 315, 971]EGFR-mediated cell signaling pathways have been implicated in several human malignant tumors, promoting tumor growth, tissue and organ invasion, angiogenesis and metastasis. EGFR overexpression and / or dysregulation are common clinical findings in solid tumors and are generally associated with an unfavorable prognosis. [Antonello, A. et al., J. Med. Chem., 2006, 49, 6642] EGFR activation also stimulates the release of vascular endothelial growth factor (VEGF), considered the primary inducer of the angiogenesis process. [Arora, A. & Scholar E., J. Pharmacol. Exp. Ther., 2005, 315, 971]

VEGF também é considerado na literatura o fator de crescimento responsável pela indução da angiogênese em tumores sólidos, promovendo ativação e migração da célula endotelial vascular; e aumentando a permeabilidade vascular em tumores. A etapa chave deste processo é mediada por um receptor específico de VEGFR, /.e. receptor do fator de crescimento do endotélio vascular tipo 2 (do inglês, vascular endothelial growth factor receptor 2 - VEGFR-2). [Garofalo, A. et al., J. Med. Chem., 2012, 55, 1189]VEGF is also considered in the literature the growth factor responsible for inducing angiogenesis in solid tumors, promoting vascular endothelial cell activation and migration; and increasing vascular permeability in tumors. The key step of this process is mediated by a specific VEGFR receptor, e.g. vascular endothelial growth factor receptor 2 (VEGFR-2). [Garofalo, A. et al., J. Med. Chem., 2012, 55, 1189]

As tirosina cinases receptoras EGFR e VEGFR-2 são intimamenteEGFR and VEGFR-2 receptor tyrosine kinases are intimately

relacionadas, exercendo papel relevante no crescimento tumoral e angiogênese. A relação entre estas tirosina cinases no tratamento do câncer também é conhecida, /.e. a inibição da sinalização mediada pelo VEGFR-2 contribui para os efeitos antitumorais dos inibidores de EGFR; enquanto que a superexpressão do fator de crescimento 'VEGF mediada por vias IO independentes do receptor EGFR é considerada um dos possíveis mecanismos de indução de resistência à terapia anti-EGFR. [Tabernero, J., Mol. Cancer Res., 2007, 5, 203]relevant role in tumor growth and angiogenesis. The relationship between these tyrosine kinases in cancer treatment is also known, e.g. inhibition of VEGFR-2 mediated signaling contributes to the antitumor effects of EGFR inhibitors; whereas EGFR receptor-independent pathway-mediated VEGF growth factor overexpression of VEGF is considered to be one of the possible induction mechanisms of resistance to anti-EGFR therapy. [Tabernero, J. Mol. Cancer Res., 2007, 5, 203]

Deste modo, as tirosina cinases EGFR e VEGFR-2 são alvos terapêuticos validados no tratamento do câncer e diversos inibidores já são 15 aprovados para uso clínico em tumores sólidos em que se observa superexpressão destas proteínas cinases, a exemplo dos inibidores apresentados na Figura 1. [Arora, A. & Scholar E., J. Pharmacol. Exp. Ther., 2005, 315, 971] [Antonello, A. et al., J. Med. Chem., 2006, 49, 6642] [McTigue, M. et ai, PNAS, 2012, 109, 18281]Thus, EGFR and VEGFR-2 tyrosine kinases are validated therapeutic targets in the treatment of cancer and several inhibitors are already approved for clinical use in solid tumors where overexpression of these protein kinases is observed, such as the inhibitors shown in Figure 1. [Arora, A. & Scholar E., J. Pharmacol. Exp. Ther., 2005, 315, 971] [Antonello, A. et al., J. Med. Chem., 2006, 49, 6642] [McTigue, M. et al., PNAS, 2012, 109, 18281]

Resistência secundária após os benefícios iniciais observados com oSecondary resistance after the initial benefits observed with the

tratamento empregando os inibidores de EGFR disponíveis na clínica, e.g. compostos 1, 2 e 3 (Figura 1), ainda consiste em um grande desafio na terapia do câncer, indicando a necessidade de desenvolvimento de novas alternativas terapêuticas [Usui, T. et al., Bioorg. Med. Chem. Lett., 2008, 18, 285] Desta 25 maneira, a inibição dual das tirosina cinases EGFR e VEGFR-2 representa uma abordagem promissora para o tratamento de tumores sólidos malignos, uma vez que a inibição do VEGFR-2 é capaz de aumentar a eficácia associada à inibição do EGFR devido a um efeito sinérgico. [Garofalo, A. et al., J. Med. Chem., 2012, 55, 1189]Treatment using clinically available EGFR inhibitors, eg compounds 1, 2 and 3 (Figure 1), still constitutes a major challenge in cancer therapy, indicating the need for the development of new therapeutic alternatives [Usui, T. et al. Bioorg. Med. Chem. Lett., 2008, 18, 285] Thus, dual inhibition of EGFR and VEGFR-2 tyrosine kinases represents a promising approach for the treatment of solid malignant tumors, as inhibition of VEGFR-2 is able to increase efficacy associated with EGFR inhibition due to a synergistic effect. [Garofalo, A. et al., J. Med. Chem., 2012, 55, 1189]

A literatura patentária contém diversos exemplos de compostos queThe patent literature contains several examples of compounds that

atuam na inibição das tirosinas cinases EGFR e VEGFR-2.
