Discovery of 6alpha-ethyl-23(S)-methylcholic acid (S-EMCA, INT-777) as a potent and selective agonist for the TGR5 receptor, a novel target for diabesity.
TLDR
Lead optimization efforts that have led to the discovery of 6alpha-ethyl-23(S)-methylcholic acid (S-EMCA, INT-777) as a novel potent and selective TGR5 agonist with remarkable in vivo activity are reported. Expand
Modulation of the kynurenine pathway in search for new neuroprotective agents. Synthesis and preliminary evaluation of (m-nitrobenzoyl)alanine, a potent inhibitor of kynurenine-3-hydroxylase.
The synthesis of (o-nitrobenzoyl)-, (m-nitrobenzoyl)-, and (p-nitrobenzoyl)alanine (o-, m-, and p-NBA), three new kynurenine analogues, and their evaluation as inhibitors of kynureninase andExpand
Correlation between CMC and chromatographic index: simple and effective evaluation of the hydrophobic/hydrophilic balance of bile acids
TLDR
While the CMC was calculated using the noninvasive conductimetric method, the RP-HPLC mobility was assessed by measuring the retention factor at several mobile phase compositions and extrapolating back to the pure aqueous mobile phase, and the correlation of the C MC with the derived chromatographic hydrophobic index ϕ0 was satisfactory.

Determination of bile salt critical micellization concentration on the road to drug discovery.
TLDR
An extraordinary variety of different analytical techniques and methods have been proposed along the years with the aim of better identifying the start of the self-aggregation process of BS monomers, with the result that a number of both invasive and non-invasive approaches have been developed along with a limited number of indirect chromatographic-based estimation strategies.

Thiokynurenates prevent excitotoxic neuronal death in vitro and in vivo by acting as glycine antagonists and as inhibitors of lipid peroxidation.
TLDR
7-Cl-thiokynurenic acid was particularly potent to prevent excitotoxic neuronal death in cultured cerebellar granule cells and may be ascribed to inhibition of lipid peroxidation. Expand
Cysteine-based chiral selectors for the ligand-exchange separation of amino acids.
TLDR
A new descriptive structure-separation relationship study through molecular surface (Jurs) and shape (Shadow) descriptors provided evidence that specific physico-chemical features of the employed chiral selector result decisive in establishing which property of the analyte is responsible for the enantiorecognition accomplishment.

Synthesis and activity of enantiopure (S) (m-nitrobenzoyl) alanine, potent kynurenine-3-hydroxylase inhibitor
Abstract The enantioselective synthesis of S (+) ( m -nitrobenzoyl)alanine along with the inhibition of kynurenine-3-hydroxylase and kynureninase activity are reported.
Synthesis and pharmacological characterization of all sixteen stereoisomers of 2-(2'-carboxy-3'-phenylcyclopropyl)glycine. Focus on (2S,1'S,2'S,3'R)-2-(2'-carboxy-3'-phenylcyclopropyl)glycine, a
All 16 2-(2‘-carboxy-3‘-phenylcyclopropyl)glycine (PCCGs) stereoisomers 32−47 have been prepared from the corresponding racemic aldehydes 12−15 following an enantiodivergent synthetic protocol.Expand
