The present invention relates to acyl-hydrazone compounds, in particular 3,4,5-trimethoxyphenyl-hydrazide derivatives, as well as the oxadiazole analogs thereof and other similar compounds, and to the pharmaceutical use of the same for the treatment of various diseases associated with cell proliferation, such as leukemias, including acute lymphoblastic leukemia (ALL), tumours and inflammation. Acyl-hydrazones have been obtained having activity similar to that of the compound used as a standard in experiments (colchicine). The greater selectivity of the compounds according to the invention is an important feature, associated with fewer side effects than the pharmaceuticals used at present in clinical treatments. The synthetised acyl-hydrazones, more particularly the compounds 02 and 07, exhibited important antileukemic activity, which suggests 02 and 07 as candidates to pharmaceutical prototypes, or to pharmaceuticals for the treatment of leukemias, in particular acute lymphoblastic leukemia (ALL), tumours and other proliferative diseases, such as inflammation. The action mechanism of the most active compounds was determined by using DNA microarrays and subsequent tests indicated by the chip, besides selectivity studies in healthy human lymphocytes.
本发明涉及酰基腙化合物,特别是3,4,5-三甲氧基苯基腙衍生物,以及其噁二唑类似物和其他类似化合物,以及它们在治疗与细胞增殖相关的各种疾病,如白血病(包括急性淋巴细胞白血病(ALL))、肿瘤和炎症方面的药用。已获得具有与实验中使用的化合物(秋水仙碱)相似活性的酰基腙。根据本发明的化合物具有更大的选择性,与目前在临床治疗中使用的药物相比,副作用更少是一个重要特征。合成的酰基腙,尤其是化合物02和07,表现出重要的抗白血病活性,这表明02和07可能成为药物原型的候选,或用于治疗白血病,特别是急性淋巴细胞白血病(ALL)、肿瘤和其他增殖性疾病,如炎症的药物。最活性化合物的作用机制是通过使用DNA微阵列确定的,并且通过芯片指示的后续测试,以及对健康人类淋巴细胞的选择性研究。
