Abstract
YM-254890 and FR900359 are potent and selective inhibitors of the Gq/11-signaling pathway. As such, they have been attractive targets for both synthesis and biological studies. Yet in spite of this effort, a versatile synthetic approach to the molecules that allows for the rapid construction of a variety of non-natural and labelled analogs and an increase in the amount of those analogs available remains elusive. We report here a convergent building block approach to the molecules that can solve this challenge.

Abstract
The cycloaddition reaction of N-hydroxysuccinimide ester and isocyanatoacetate catalyzed by copper was described. A series of 4,5-disubstituted oxazole compounds, including ones derived from natural fatty acids, drugs, amino acids, and peptides, were obtained in moderate to high yields. The derivatization reaction was explored. The reaction mechanism was discussed.

Anal Bioanal Chem 2020; 412:5525-5535. [PMID: 32564119 DOI: 10.1007/s00216-020-02772-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2020] [Revised: 06/03/2020] [Accepted: 06/12/2020] [Indexed: 10/24/2022]
Abstract
Mass spectrometry (MS) binding assays are a label-free alternative to radioligand or fluorescence binding assays, so the readout is based on direct mass spectrometric detection of the test ligand. The study presented here describes the development and validation of a highly sensitive, rapid, and robust MS binding assay for the quantification of the binding of the metabotropic glutamate 5 (mGlu5) negative allosteric modulator (NAM), MPEP (2-methyl-6-phenylethynylpyridine) at the mGlu5 allosteric binding site. The LC-ESI-MS/MS (liquid chromatography-electrospray ionization-tandem mass spectrometric) analytical method was established and validated with a deuterated analogue of MPEP as an internal standard. The developed MS binding assay described here allowed for the determination of MS binding affinity estimates that were in agreement with affinity estimates obtained from a tritiated MPEP radioligand saturation binding assay, indicating the suitability of this methodology for determining affinity estimates for compounds that target mGlu5 allosteric binding sites.
