Discovery of cyanopyridine scaffold as novel indoleamine-2,3-dioxygenase 1 (IDO1) inhibitors through virtual screening and preliminary hit optimisation
摘要:
With the aim of discovering novel IDO1 inhibitors, a combined similarity search and molecular docking approach was employed to the discovery of 32 hit compounds. Testing the screened hit compounds has led to several novel submicromolar inhibitors. Especially for compounds LVS-019 with cyanopyridine scaffold, showed good IDO1 inhibitory activity. To discover more compounds with similar structures to LVS-019, a shape-based model was then generated on the basis of it and the second-round virtual screening was carried out leading to 23 derivatives. Molecular docking studies suggested a possible binding mode of LVS-019, which provides a good starting point for the development of cyanopyridine scaffold compounds as potent IDO1 inhibitor. To improve potency of these hits, we further designed and synthesised another 14 derivatives of LVS-019. Among these compounds, LBJ-10 showed improved potency compared to the hits and displayed comparable potency to the control GDC-0919 analogue. LBJ-10 can serve as ideal leads for further modifications as IDO1 inhibitors for cancer treatment.
参考已报道的基于药效团的虚拟筛选的“热门”化合物A的结构信息,设计并合成了一系列新型含噻吩基吡啶基和硫醚/亚砜/砜的乙酰胺衍生物。新化合物的结构经1 H NMR、 13 C NMR和HRMS确证。 A的单晶结构为首次报道。所有新合成的化合物均对粘虫和小菜蛾进行了杀虫活性评价。通过逐步的结构优化,发现了高效杀虫剂,特别是对小菜蛾的杀虫剂,以及噻吩基吡啶和砜。含硫醚的乙酰胺Iq 、 Io 、 Ib和A与本研究中的防治杀虫剂杀螟丹、杀铃脲和氯虫苯甲酰胺相当,可作为新型杀虫剂创新研究的新型先导结构。此外,一些化合物,如A 、 Ih 、 Id 、 Io和Iq也对梨轮纹菌、谷丝核菌和核盘菌表现出良好的杀菌活性,可为新型杀菌剂的设计和开发提供有益的指导。
