Discovery of protein–protein binding disruptors using multi-component condensations small molecules
摘要:
A series of small molecule compounds interfering with the binding process of VEGF and NRP1 has been identified and further optimized. Full synthetic details as well as SAR are reported which demonstrate that expeditious MCC-based syntheses may lead to valuable molecules addressing challenging targets such as protein-protein interactions. Preliminary functional assay data confirm that these compounds may be further developed toward drug candidates. (c) 2006 Elsevier Ltd. All rights reserved.

report relatively simple and cost-effective orthogonal tandem catalysis, namely Ag2O in conjunction with Cs2CO3 serves to promote a multicomponent tandem reaction forming two new C–C and one new C–N bonds. 4H-Quinolizin-4-ones, key skeletal components in a variety of biologically active molecules, were obtained with yields up to 99%. The present approach features a broad substrate scope and mild reaction
本文使用二氧化碳作为C1的前体,我们报告了相对简单且经济高效的正交串联催化,即Ag 2 O与Cs 2 CO 3结合可促进多组分串联反应,形成两个新的C–C和一个新的C– N个债券。获得了4 H -Quinolizin-4-ones,这是多种生物活性分子中的关键骨架成分,产率高达99%。本方法具有广泛的底物范围和温和的反应条件,并受益于使用具有成本效益的反应和催化剂。
Palladium-catalyzed direct deprotonative arylation of 2-pyridylacetonitriles: Facile synthesis of alpha-aryl-2-pyridylacetonitrile
α-Aryl-2-pyridylacetonitrile, an important chemical intermediate, was synthesized via direct deprotonative arylation of 2-pyridylacetonitrile with aryl bromides. Pd(OAc)2/NixantPhos-based catalysis system promoted this arylation reaction to furnish diverse α-aryl-2-pyridylacetonitrile derivatives in wide range function group tolerance and high yield (80%-97%).
