Direct high-performance liquid chromatographic enantioseparation of apolar beta-amino acids on a quinine-derived chiral anion-exchanger stationary phase
J Chromatogr A 2002 Apr 26;955(1):141-50.PMID:12061560DOI:10.1016/s0021-9673(02)00192-9.
A quinine-derived chiral anion-exchanger stationary phase was applied for the direct high-performance liquid chromatographic separation of the enantiomers of N-protected unusual beta-amino acids, i.e. 3-Aminobutanoic acid, 3-aminopentanoic acid, 3-amino-4-methylpentanoic acid, 3-amino-4,4-dimethylpentanoic acid, 3-amino-4-methylhexanoic acid, 3-amino-4-ethylhexanoic acid, 3-amino-3-cyclohexylpropanoic acid, 3-amino-3-(3-cyclohexen-1-yl)propanoic acid and 3-amino-3-phenylpropanoic acid. The readily prepared N-2,4-dinitrophenyl derivatives were well separable, with good efficiency and high resolution. The chromatographic conditions (eluent composition, pH and buffer concentration) were varied to achieve optimal separation. In some cases, the elution sequences of the enantiomers of the derivatives were determined.
Biochemical characterization and structural insight into aliphatic β-amino acid adenylation enzymes IdnL1 and CmiS6
Proteins 2017 Jul;85(7):1238-1247.PMID:28316096DOI:10.1002/prot.25284.
Macrolactam antibiotics such as incednine and cremimycin possess an aliphatic β-amino acid as a starter unit of their polyketide chain. In the biosynthesis of incednine and cremimycin, unique stand-alone adenylation enzymes IdnL1 and CmiS6 select and activate the proper aliphatic β-amino acid as a starter unit. In this study, we describe the enzymatic characterization and the structural basis of substrate specificity of IdnL1 and CmiS6. Functional analysis revealed that IdnL1 and CmiS6 recognize 3-Aminobutanoic acid and 3-aminononanoic acid, respectively. We solved the X-ray crystal structures of IdnL1 and CmiS6 to understand the recognition mechanism of these aliphatic β-amino acids. These structures revealed that IdnL1 and CmiS6 share a common recognition motif that interacts with the β-amino group of the substrates. However, the hydrophobic side-chains of the substrates are accommodated differently in the two enzymes. IdnL1 has a bulky Leu220 located close to the terminal methyl group of 3-aminobutanoate of the trapped acyl-adenylate intermediate to construct a shallow substrate-binding pocket. In contrast, CmiS6 possesses Gly220 at the corresponding position to accommodate 3-aminononanoic acid. This structural observation was supported by a mutational study. Thus, the size of amino acid residue at the 220 position is critical for the selection of an aliphatic β-amino acid substrate in these adenylation enzymes.

Synthesis of N-substituted acyclic β-amino acids and their investigation as GABA uptake inhibitors
Eur J Med Chem 2013 Jul;65:487-99.PMID:23770450DOI:10.1016/j.ejmech.2013.04.063.
In this publication, we describe the synthesis of new inhibitors for the GABA transporter subtypes GAT1 and especially GAT3. We started with 3-aminopropanoic acid possessing a distinct preference for GAT3 in comparison to GAT1 and furthermore its homolog 3-Aminobutanoic acid. A series of respective N-substituted amino acids was synthesized by selective N-monoalkylation of these parent structures with 6 different arylalkyl alcohols via a Mitsunobu-type reaction. The resulting compounds were investigated for their inhibitory potency GABA transporter subtypes. Among all tested compounds the 4,4-diphenylbut-3-enyl substituted 3-Aminobutanoic acid (rac)-6b showed highest potency with a pIC50 value of 5.34 at GAT1. Unfortunately, the expected GAT3 potency for 2-[tris(4-methoxyphenyl)methoxy]ethyl substituted derivatives was not as high as observed for the respective nipecotic acid derivatives.
Vascular Endothelial Growth Factor May Be Involved in the Behavioral Changes of Progeny Rats after Exposure to Ceftriaxone Sodium during Pregnancy
J Microbiol Biotechnol 2022 Jun 28;32(6):699-708.PMID:35484974DOI:10.4014/jmb.2111.11048.
Antibiotic exposure during pregnancy have an adversely effects on offspring behavior and development. However, its mechanism is still poorly understood. To uncover this, we added ceftriaxone sodium to the drinking water of rats during pregnancy and conducted three-chamber sociability test, open-field test, and Morris water maze test in 3- and 6-week-old offspring. The antibiotic group offspring showed lower sociability and spatial learning and memory than control. To determine the role of the gut microbiota and their metabolites in the changes in offspring behavior, fecal samples of 6-week-old offspring rats were sequenced. The composition of dominant gut microbial taxa differed between the control and antibiotic groups. KEGG pathway analysis showed that S24-7 exerted its effects through the metabolic pathways including mineral absorption, protein digestion and absorption, Valine, leucine, and isoleucine biosynthesis. Correlation analysis showed that S24-7 abundance was negatively correlated with the level of VEGF, and metabolites associated with S24-7-including 3-Aminobutanoic acid, dacarbazine, L-leucine, 3-ketosphinganine, 1-methylnicotinamide, and N-acetyl-L-glutamate-were also significantly correlated with VEGF levels. The findings suggest that antibiotic exposure during pregnancy, specifically ceftriaxone sodium, will adversely affects the behavior of offspring rats due to the imbalance of gut microbiota, especially S24-7, via VEGF and various metabolic pathways.
