Synthesis and functionalization of the 3-(1,3,4-oxadiazol-2-yl)-1h-indoles
摘要:
A modified method is proposed for the preparative synthesis of 3-(1,3,4-oxadiazol-2-yl)-1H-indoles in high yield. We are the first to demonstrate the functionalization of this heterocyclic system by alkylation. In particular, syntheses are reported for [3-(1,3,4-oxadiazol-2-yl)-1H-indol-1-yl]acetic acids and their amide derivatives.

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.

A facilesynthesis of 1,3,4-oxadiazoles and 1,3,4-oxadiazoles-d5 via [4 + 1] cyclization of ClCF2COONa with non-amine compounds containing amino groups is developed. Of note, this is the first time that halofluorinated compounds are used as C1 synthon to construct deuterated nitrogen-heterocyclic compounds. The current protocol features simple operation, readily accessible raw materials, wide substrate

A presente invenção refere-se a compostos acil-hidrazonas, especialmente as derivados da 3,4,5-trimetoxifenil-hidrazida, bem como a seus análogos oxadiazóis e outros compostos semelhantes, e aplicação farmacêutica dos mesmos no tratamento de diferentes doenças associadas à proliferação celular, como leucemias, incluindo leucemia linfóide aguda (LLA), tumores e inflamação. Foram obtidas acil-hidrazonas com atividade semelhante ao composto utilizado como padrão nos experimentos (colchicina). A maior seletividade dos compostos apresentados nesta invenção é uma característica importante relacionada com menores efeitos colaterais que os fármacos atualmente empregados na clínica. As acil- hidrazonas sintetizadas, mais especificamente os compostos 02 e 07, apresentaram importante atividade antileucêmica, o que indica 02 e 07 como candidatos a protótipos de fármacos, ou fármacos, para o tratamento de leucemias, especialmente leucemia linfóide aguda (LLA), tumores e outras doenças proliferativas, como inflamação. A determinação do mecanismo de ação dos compostos mais ativos foi realizada pela utilização de microarranjos de DNA e testes subsequentes indicados através do chip, além dos estudos de seletividade em linfócitos humanos saudáveis.
