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。

Double asymmetric induction has been employed as a tool to optimise pyrazolidinone-derived organocatalysts for the asymmetric iminiumion catalysed Diels–Alder reaction. Mechanistic studies revealed a superior hydrazide catalyst deriving from methanolysis of the chiral pyrazolidinone precursor. This catalyst displays unusually high endo diastereoselectivity and good enantioselectivity with a range

promoted Diels–Alderreactions evaluated. Systematic variation of the C(5)- and N(2)-substituents indicates that the incorporation of an electron withdrawing substitutent at N(2) and either a Ph or CF3 substitution at C(5) results in optimal catalytic activity. The diastereoisomeric resolution of a model C(5)-Ph substituted pyrazolidinone and its ability to impart modest levels of asymmetric induction

still suffers from laborious screening workflows and a limited diversity in the fragments applied. Presented here is the design, synthesis, and biological evaluation of the first fragment library specifically tailored to tackle both these challenges. The 3F library of 115 fluorinated, Fsp3 -rich fragments is shapediverse and natural-product-like with desirable physicochemical properties. The library
