Imidazo[2,1-b]thiazole guanylhydrazones as RSK2 inhibitors
摘要:
The activity of a series of imidazo[2,1-b]thiazole guanylhydrazones as inhibitors of p90 ribosomal S6 kinase 2 (RSK2) is described. It was found that a small subset of compounds show both potent inhibition of RSK2 kinase activity and tumor cell growth in vitro. Detailed study of one of the most active compounds indicates a high degree of selectivity for inhibition of RSK2 compared to a spectrum of other related kinases. Selective inhibition of the MCF-7 breast tumor cell line compared to MCF-10A non-transformed cells, as well as selective inhibition of the biomarker GSK3 provides evidence that the compounds can affect the RSK2 target in cells.

Diversity-Oriented Synthesis of Functionalized Imidazopyridine Analogues with Anti-Cancer Activity through a Transition-Metal Free, One-pot Cascade Reaction
A transition‐metalfree, high yielding and efficient three‐component reaction was designed and incorporated into two sequential oxidation and cyclization reaction cascades in one‐pot with the assistance of microwave irradiation. A chemical collection of functionalized 3‐substituted imidazopyridines was prepared by means of the mild reaction and simple operational procedure. The reaction has a broad
设计了无过渡金属,高产率和高效的三组分反应,并借助微波辐射将其整合到一个锅中的两个顺序的氧化和环化反应级联中。通过温和的反应和简单的操作步骤,制备了功能化的3-取代的咪唑并吡啶的化学物质。该反应对各种取代的羰基醛,苯胺和2-苯基-咪唑并[1,2- a ]吡啶具有宽泛的耐受性。进行了几种癌细胞系的筛选。化合物9 i对HeLa细胞系表现出良好的效力,这项工作证实了产生生物活性化合物的方法的可行性。
