A histona desacetilase 2 (HDAC2) é um membro fundamental da família das histonas desacetilases de classe I, que desempenha um papel crítico na regulação epigenética da expressão genética. Esta enzima modifica a estrutura da cromatina removendo os grupos acetilo dos resíduos de lisina das proteínas histónicas, influenciando assim a transcrição dos genes. Embora a HDAC2 funcione em processos celulares normais, está frequentemente sobre-expressa em vários tipos de cancro e desempenha um papel significativo no crescimento, proliferação e diferenciação das células tumorais [1]. Como tal, a HDAC2 é considerada um alvo terapêutico promissor no tratamento do cancro.Neste estudo, as caraterísticas de ligação de uma nova pequena molécula que tem como alvo a enzima HDAC2 foram analisadas em pormenor. Utilizando abordagens computacionais, foram realizadas simulações de docking molecular e de dinâmica molecular (MD) para investigar o comportamento de ligação da molécula ao local ativo da HDAC2. Os resultados do docking revelaram que o composto se liga ao sítio ativo da enzima com elevada afinidade, formando ligações de hidrogénio e interações hidrofóbicas com resíduos de aminoácidos críticos.
