We report a new set of reactions based on the Pd-catalyzed alkylation of methylene C(sp3)-H bonds of aliphatic quinolyl carboxamides with α-haloacetate and methyl iodide and applications in the stereoselective synthesis of various β-alkylated α-amino acids. These reactions represent the first generally applicable method for the catalytic alkylation of unconstrained and unactivated methylene C-H bonds with high synthetic relevance. When applied with simple isotope-enriched reagents, they also provide a convenient and powerful means to site-selectively incorporate isotopes into the carbon scaffolds of amino acid compounds.

Prolylcarboxypeptidase (PrCP) is a serine protease that may have a role in metabolism regulation. A class of reversible, potent, and selective PrCP inhibitors was developed starting from a mechanism based design for inhibiting this serine protease. Compound 8o inhibits human and mouse PrCP at IC 50 values of 1 and 2 nM and is not active (IC50 > 25 μM) against a panel of closely related proteases. It has lower serum binding than its close analogues and is bioavailable in mouse. Subchronic dosing of 8o in PrCP-/- and WT mice at 100 mg/kg for 5 days resulted in a 5% reduction in body weight in WT mice and a 1% reduction in PrCP KO mice.

Amino acids with lipophilic side chains that contain more than one functional group on the β-carbon, i.e. a β-branched hydrocarbon moiety, are required in position 5 of angiotensin II (AII) analogue with potent agonist activity.This requirement for agonis
