基于片段的药物发现(FBDD)是学术界和制药行业中发现早期潜在候选药物的一种流行方法。尽管其用途广泛,但该方法仍存在费时费力的筛选工作流程,并且所用片段的多样性有限。这里介绍的是第一个片段库的设计,合成和生物学评估,这些片段库专门为应对这些挑战而设计。115个富含Fsp3的氟化片段的3F文库形状多样,呈天然产物状,具有理想的理化性质。该文库非常适合在19 F NMR和随后的1 H NMR方法的两阶段工作流程中通过NMR光谱进行快速有效的筛选。在3F库中的片段支架中,针对四种不同蛋白质靶标的命中分布广泛,使用二级检测的确证率达到67%。该集合是为19 F NMR筛选量身定制的第一个合成片段文库,结果表明该方法应在FBDD社区中得到广泛应用。

The synthesis and CRF receptor binding affinities of several new series of N-aryltriazolo- and -imidazopyrimidines and -pyridines are described. These cyclized systems were prepared from appropriately substituted diaminopyrimidines or -pyridines by nitrous acid, orthoester, or acyl halide treatment. Variations of amino (ether) pendants and aromatic substituents have defined the structure-activity relationships

An absorbent composition including an amino-siloxane is presented. The amino- siloxane includes structure (I): wherein R1 is independently at each occurrence a C1-C6 aliphatic or aromatic radical; R2 is independently at each occurrence a C2-C10 aliphatic or aromatic radical; and R3 is independently at each occurrence a C1-C18 aliphatic or aromatic radical or R4, wherein R4 comprises structure (II): wherein X is independently at each occurrence an electron donating group; and n is at least 1. Methods of reducing an amount of carbon dioxide in a process stream using the absorbent composition are also presented.
