Application of a Ugi multicomponent reaction to oxo acids 4 allows the formation of potentially antimitotic indolobenzazepinones of type 5 in good yields of up to 72 %, whereas the same transformation from the starting substrate 6 gives access to analogues of paullone with yields of up to 89 %. The reaction could be applied to a wide range of isocyanides, thereby ensuring introduction of molecular

The present invention relates to indole derivatives of formula (I') as CK2 inhibitor and pharmaceutical compositions comprising the same. The present invention further relates to the use of such compounds of formula (I) for use for preventing and/or treating a cancer.
developed as Lamellarin isosters. Synthesis was achieved from indoles after a four-step pathway sequence involving C-3 iodination, a Suzuki cross-coupling reaction, and a one pot deprotection/lactonisation step. Twenty final compounds were tested in order to determine their activity against topoisomerase I and kinases, the two major biologicalactivities of Lamellarins. One newly synthesized derivative exhibited
开发了取代的chromeno [3,4- b ]吲哚文库作为lamellarin等位基因。在涉及C的四步路径序列之后,由吲哚完成合成-3碘化,Suzuki交叉偶联反应和一锅脱保护/内酯化步骤。测试了二十种最终化合物以确定它们对拓扑异构酶I和激酶(Lamellarins的两种主要生物学活性)的活性。一种新合成的衍生物显示出强大的拓扑异构酶活性,可与参比化合物(例如喜树碱和lamellarin)相比,但激酶抑制作用较弱。其他两种先导化合物被鉴定为新的纳摩尔DYRK1A抑制剂,其他几种药物影响亚微摩尔范围内的激酶。这些结果将使我们能够使用chromeno [3,4- b ]吲哚作为药效团来开发有效治疗涉及DYRK1A的神经系统或肿瘤性疾病的方法。

A series of 5-alkylindolobenzazepin-7-ones was synthesized by Suzuki coupling between 3-iodoindole-2-carboxylates and the appropriate alpha-alkylbenzylamino o-boronic acids followed by cyclization to the lactam. Derivatives having a linear alkyl chain at C5 were found to be highly cytotoxic to KB cells with IC50 values in the 30-80 nM range. These compounds also inhibited the polymerization of tubulin with IC50's of 1-2 mu M. Compound 4f ((S)-5-ethyl) showed comparable antiproliferative activities (IC50's of 30-70 nM) in a variety of cancer cell lines, cell growth being arrested at the G2/M phase. Compound 4f induced apoptosis in a dose-dependent manner in three different cancer cell lines and was shown to affect cell morphology in a manner consistent with its inhibitory action on tubulin polymerization. Using the experimental model of glioma grafted on the chick chorio-allantoic membrane, local treatment with compound 4f markedly reduced tumor progression.
Synthesis and evaluation of heterocycle structures as potential inhibitors of Mycobacterium tuberculosis UGM
In this study, we screen three heterocyclic structures as potential inhibitors of UDP-galactopyranose mutase (UGM), an enzyme involved in the biosynthesis of the cell wall of Mycobacterium tuberculosis. In order to understand the binding mode, docking simulations are performed on the best inhibitors. Their activity on Mycobacterium tuberculosis is also evaluated. This study made it possible to highlight an "oxazepino-indole" structure as a new inhibitor of UGM and of M. tuberculosis growth in vitro.
