Parallel solution- and solid-phase synthesis of spiropyrrolo-Pyrroles as novel neurokinin receptor ligands
摘要:
The combination of a 3,5-bis(trifluoromethyl)phenyl needle with the spiropyrrolo-pyrrole motive as a privileged GPCR scaffold was the basis for designing a focused combinatorial library targeted towards the neurokinin-1 receptor. A solution- and solid-phase method is described and binding affinities of representative compounds are presented. (C) 2002 Elsevier Science Ltd. All rights reserved.

diverse covalent warheads. Our library represents a unique opportunity for the efficient integration of warhead-optimization and target-validation into the covalent drug development process. Screening this probe kit against multiple kinases could experimentally characterize the accessibility and reactivity of the targeted cysteines and helped to identify suitable warheads for designedcovalent inhibitors

Organocatalytic enantioselective synthesis of N-alkyl/aryl-3-alkyl-pyrrolidine-2,5-dione in brine
A highly enantioselective approach has been developed for synthesising chiral succinimide derivatives via asymmetric Michael addition of diketones to maleimide using dihydroquinine as a catalyst in brine. The Michael adducts were obtained in yields up to 98% and with enantiomeric excesses up to 98% ee. (C) 2016 Elsevier Ltd. All rights reserved.

Assessment of Tractable Cysteines for Covalent Targeting by Screening Covalent Fragments
toolbox of covalentfragments containing chemically diverse electrophilic warheads is presented. By screening this library against a set of enzymes amenable for covalent inhibition, we experimentally characterized the accessibility and reactivity of targetedcysteines. We propose this approach be used as an experimental method for warhead selection in the development of targetedcovalent inhibitors
