Abstract in Portuguese
Histórico: A proteína de choque térmico 90 é uma chaperona molecular necessária para a estabilidade e função de várias proteínas clientes que promovem o crescimento e/ou sobrevivência de células cancerígenas. A descoberta de inibidores de Hsp90 surgiu como um alvo atraente de pesquisa em terapêuticas contra o câncer. Produtos naturais como geldanamicina e radicicol são inibidores de Hsp90 estabelecidos, mas enfrentam limitações com toxicidade e inatividade, por estudos in vivo, respectivamente. No entanto, eles estabelecem o ponto de partida lógico para o design de novos congêneres sintéticos ou semissintéticos como inibidores de Hsp90. Objetivo: Neste artigo, o design de fármacos baseado na estrutura de análogos de 2-aril/heteroarilideno-6-hidroxibenzofuran-3(2H)-ona substituídos para otimizar e imitar as interações farmacofóricas do inibidor de Hsp90 válido radicicolis é focado. Método: O estudo de encaixe in silico foi realizado pelo Surflex dock-Geom (SYBYL-X 1.2 drug discovery suite) e os ligantes projetados foram sintetizados quimicamente pelo método convencional usando resorcinol e clororesorcinol como materiais de partida. A busca de similaridade química bidimensional foi realizada para identificar o espaço químico da série 'SY' em comparação com os inibidores de Hsp90 relatados. O ensaio de proliferação celular in vitro (método de redução de resazurina) e a investigação proteômica (DARTS) foram realizados em lisado de células inteiras para avaliar a atividade anticâncer. Resultados: As estruturas químicas de todos os compostos sintetizados foram confirmadas por IR, 1H-NMR e análise espectral de massa. Os resultados da busca de similaridade química mostram que a série SY se encaixa no espaço químico definido pelos inibidores de Hsp90 existentes. O ensaio de proliferação celular in vitro, contra linhas celulares de melanoma humano e câncer de mama, identificou 'SY3' como o agente anticâncer promissor entre as séries. Conclusão: Estudos de encaixe, busca de similaridade química 2D, ensaio de redução de resazurina e análise proteômica qualitativa identificam 'SY3' como um inibidor promissor de Hsp90 entre as séries.
Abstract
Background: Heat shock protein 90 is a molecular chaperone required for the stability and function of several client proteins that promote cancer cell growth and/or survival. Discovery of Hsp90 inhibitors has emerged as an attractive target of research in cancer therapeutics. Natural products like geldanamycin and radicicol are established Hsp90 inhibitors, but face limitations with toxicity and inactivity, by in vivo studies respectively. However, they lay the logical starting point for the design of novel synthetic or semi-synthetic congeners as Hsp90 inhibitors. Objective: In this article, the structure based drug design of substituted 2-aryl/heteroarylidene-6- hydroxybenzofuran-3(2H)-one analogues to optimize and mimic the pharmacophoric interactions of the valid Hsp90 inhibitor radicicolis focused. Method: In silico docking study was performed by Surflex dock-Geom (SYBYL- X 1.2 drug discovery suite) and the designed ligands were chemically synthesized by conventional method using resorcinol and chlororesorcinol as starting materials. Two dimensional chemical similarity search was carried out to identify the chemical space of 'SY' series in comparison with reported Hsp90 inhibitors. The in vitro cell proliferation assay (resazurin reduction method) and proteomic investigation (DARTS) was carried out on whole cell lysate to evaluate anticancer activity. Results: The chemical structures of all the synthesized compounds were confirmed by IR, 1H-NMR and Mass spectral analysis. The results of chemical similarity search show that SY series fit it in the chemical space defined by existing Hsp90 inhibitors. In vitro cell proliferation assay, against human melanoma and breast cancer cell lines, identified 'SY3' as the promising anticancer agent amongst the series. Conclusion: Docking studies, 2D chemical similarity search, resazurin reduction assay and qualitative proteomic analysis identify 'SY3'as a promising Hsp90 inhibitor amongst the series.
