Disclosed herein are novel bifunctional compounds formed by conjugating BTK inhibitor moieties with E3 ligase Ligand moieties, which function to recruit targeted proteins to E3 ubiquitin ligase for degradation, and methods of preparation and uses thereof.
by 1H, 13C, and 15N NMR spectroscopies. The results were compared with 13C and 15N CPMAS NMR and IR spectral as well as with X-ray structural data. Intermolecular interactions in solution and in solidstate were found to have a similar nature. Relatively strong Namide−H···Npyridine intermolecular hydrogen bonds enable dimerization to take place. Steric interactions in N-pivaloyl- and N-1-adamantylcarbonyl
通过1 H,13 C和15 N NMR光谱研究了2-酰基氨基吡啶及其6-甲基衍生物在氯仿溶液中的聚集。将结果与13 C和15 N CPMAS NMR和IR光谱以及X射线结构数据进行了比较。发现溶液中和固态的分子间相互作用具有相似的性质。相对强的N酰胺-H···N吡啶分子间氢键使二聚作用得以发生。N-新戊酰和N中的立体相互作用-1-金刚烷基羰基以及由6-甲基引起的那些阻碍了由N酰胺-H··N吡啶分子间氢键稳定的二聚体聚集体的形成。通常,DFT优化的氯仿溶液中聚集体的几何形状与X射线晶体结构一致。还发现了C = O基团的拉伸振动带的波数,表明存在于固态的氢键的类型。
