Synthesis and evaluation of cyclopentane-based muraymycin analogs targeting MraY
Antibiotic resistance is one of the most challenging global health issues and presents an urgent need for the development of new antibiotics. In this regard, phospho-MurNAc-pentapeptide translocase (MraY), an essential enzyme in the early stages of peptid

Enhanced enzymatic synthesis of the enantiopure intermediate for the blockbuster drug intermediate abacavir through a two-step enzymatic cascade reaction
A very efficient enzymatic two-step cascade reaction was devised (E?>?200) for the resolution of activated γ-lactams (±)-1 and (±)-2. The N-hydroxymethyl group worked as a traceless activating group, when the reactions were performed with H2O (0.5?equiv) in the presence of benzylamine (1?equiv) in i-Pr2O at 60?°C. The ring-opened enantiomerically pure γ-amino acids (1S,4R)-6 (ee?=?99%, intermediate of abacavir) and (1S,3R)-8 (ee?=?99%) and unreacted lactams (1S,4R)-1 and (1R,4S)-2 (ee???96%) were obtained in good yields (?43%). Treatment of (1S,4R)-1 and (1R,4S)-2 with 18% HCl or NH4OH resulted in (1R,4S)-6·HCl and (1S,3R)-8·HCl or (1S,4R)-3 and (1R,4S)-4 quantitatively, with ee???96%.

Identification and application of enantiocomplementary lactamases for Vince lactam derivatives
Four enzymes showing hydrolytic activity on derivatives of 2-azabicyclo[2.2.1]hept-5-en-3-one (Vince lactam) were successfully identified through analysis of protein crystal structure and amino acid sequence alignments. Enantiocomplementary activities were observed on Vince lactam and its saturated analog 2-azabicyclo[2.2.1]heptan-3-one with non-heme chloroperoxidase (CPO-T) from Streptomyces aureofaciens, cyclic imide hydrolase (CIH) from Pseudomonas putida, polyamidase (NfpolyA) from Nocardia farcinica, and amidase (AMI) from Rhodococcus globerulus, and perfect kinetic resolution was achieved (E>200). Computational analysis of amide bond resonance stabilization in lactams correlated well with the overall reactivity pattern of the lactams as a function of ring size and strain. The biocatalysts cloned and investigated in this study could be of interest for the synthesis of enantiopure carbocyclic nucleoside analogues.

Design, synthesis, and structure-activity relationship of novel CCR2 antagonists
A series of novel 1-aminocyclopentyl-3-carboxyamides incorporating substituted tetrahydropyran moieties have been synthesized and subsequently evaluated for their antagonistic activity against the human CCR2 receptor. Among them analog 59 was found to posses potent antagonistic activity.

The use of (-)-8-phenylisoneomenthol and (-)-8-phenylmenthol in the enantioselective synthesis of 3-functionalized 2-azabicyclo[2.2.1]heptane derivatives via aza-Diels-Alder reaction
The asymmetric aza-Diels-Alder reaction of the (1R)-8-phenylmenthyl or (1R)-8-phenylisoneomenthyl glyoxylate-derived N-benzylimine with cyclopentadiene resulted in the enantioselective synthesis of the corresponding pure [(1S,3-exo)-2-benzyl-2-azabicyclo[2.2.1]hept-5-ene]-3-carboxylates (80 or 69% yield, respectively). Reduction of these cycloadducts with LiAlH4 afforded pure (-)-[(1S,3-exo)-2-benzyl-2-azabicyclo[2.2.1]hept-5-en-3-yl]methanol. Furthermore, a reaction sequence based on Barbier-Wieland degradation of both (1S,3-exo)-adducts afforded pure (+)-(1R)-2-benzoyl-2-azabicyclo[2.2.1]heptan-3-one. In the course of the two transformation sequences referred, the chiral auxiliaries were recovered in a virtually quantitative way.
