Utilizing a combination of high-throughput and multi-step synthesis, SAR in a novel series of M(1) acetylcholine receptor antagonists was rapidly established. The efforts led to the discovery the highly potent M(1) antagonists 6 (VU0431263), and 8f (VU0433670). Functional Schild analysis and radioligand displacement experiments demonstrated the competitive, orthosteric binding of these compounds; human selectivity data are presented.

TLDR
This work presents an alternative approach that has a general applicability for directly obtaining diverse chiral α-substituted carboxylic acids and combines two enzyme classes, namely ERs and aldehyde dehydrogenases (Ald-DHs), in a concurrent reductive-oxidative biocatalytic cascade. Expand

TLDR
Spicing it up with fluorine: Enantiomers of α‐fluorinated capsaicin 2, have been prepared by organocatalytic electrophilic fluorination and have been used as probes for the binding conformation of Capsaicin to the TRPV1 pain receptor, suggesting an extended binding conformed along the molecular axis.

TLDR
High-throughput screening found more than 400 novel PAMs of mGluR4, and resolution of the regioisomers of the lead revealed that this compound is a mixed allosteric agonist/PAM of m GluR 4, providing continued support for mGLUR4 as a therapeutic target in PD. Expand
