palladium-catalyzed C-3 selective alkenylation of 7-azaindoles, performed in the presence of Pd(OAc)2 as the catalyst, PPh3 as the ligand, Cu(OTf)2 as an oxidative cocatalyst, and molecular oxygen (O2) as the terminal oxidant at room temperature, has been reported. This direct alkenylation strategy offers a new approach in functionalizing pharmaceutically important 7-azaindoles.
32 ± 0.26 μM, 6.27 ± 1.04 μM and 4.63 ± 0.83 μM. The structure–activity relationships (SARs) and docking studies indicated that the pyrrolo[2,3-b]pyridine derivatives bearing 4-oxo-pyridazinone moiety was superior to the pyrrolo[2,3-d]pyrimidinederivatives bearing 6-oxo-pyridazinone moiety. What's more, the target compounds modified with X and Y (X = H, Y = H) were favorable to the activity. And electron
在继续我们先前的研究中,设计,合成了带有哒嗪酮部分的八个系列的吡咯并[2,3- b ]吡啶和吡咯并[2,3- d ]嘧啶衍生物,并评估了其对四种癌细胞的体外抗肿瘤活性。线(A549,HepG2,MCF-7和PC-3)。评估了一些选定的化合物(22f,22g,26c和26e)的抗c-Met激酶活性,并根据激酶抑制活性的结果,进一步评估了化合物22g的其他四种酪氨酸激酶(Flt-3,VEGFR -2,c-Kit和EGFR)来测试基于酶的选择性。最有希望的化合物,22克与Foretinib相比,其针对A549,HepG2,MCF-7和PC-3细胞系表现出优异的活性,IC 50值分别为2.19±0.45μM,1.32±0.26μM,6.27±1.04μM和4.63±0.83μM。结构-活性关系(SARs)和对接研究表明,带有4-氧代-哒嗪酮部分的吡咯并[2,3- b ]吡啶衍生物优于带有6-氧代-吡咯并[2
Discovery of novel pyrrolo[2,3-b]pyridine derivatives bearing 4-oxoquinoline moiety as potential antitumor inhibitor
A series of pyrrolo[2,3-b]pyridine derivatives bearing 4-oxoquinoline moiety were designed, synthesized and evaluated for the anti-proliferative on three cancer cell lines (A549, HepG2 and MCF-7) in vitro. Most of the compounds showed moderate to high potency. Some excellent compounds were tested for the inhibitory activity of c-Met kinase. Compound 34 (c-Met IC50 = 17 nM) was investigated the selectivity

Alkylchlorides are bench-stable chemical feedstocks that remain among the most underutilized electrophile classes in transition metal catalysis. Overcoming intrinsic limitations of C(sp3)-Cl bond activation, we report the development of a novel organosilane reagent that can participate in chlorine atom abstraction under mild photocatalytic conditions. In particular, we describe the application of
