A new method was developed to construct a special amido bond in the presence of β-cyclodextrin. This process is similar to peptide synthesis in organisms. NMR experiments were performed to investigate the possible mechanism. This work has potential application in biomimetic peptide synthesis.

Herein, a Grubbs-catalyzed route for the synthesis of nitriles via the aerobic oxidation of primary amines is reported. This reaction accommodates a variety of substrates, including simple primary amines, sterically hindered β,β-disubstituted amines, allylamine, benzylamines, and α-amino esters. Reaction compatibility with various functionalities is also noted, particularly with alkenes, alkynes, halogens, esters, silyl ethers, and free hydroxyl groups. The nitriles were also synthesized via the oxidation of imines generated from aldehydes and NH4OAc in situ. (Figure presented.).
Novel aminopeptidase n inhibitors with improved antitumor activities

, p. 98 - 106 (2015/12/01)
A series of aminopeptidase N (APN) inhibitors were designed and synthesized. Enzyme inhibitory, docking and antiproliferative studies were performed to evaluate the derived molecules. Molecule D15, with IC50 values of 10.9 μM, showed the best performance in the APN enzymatic inhibition assay. The binding pattern of molecule D9 and D15 in the active site of APN was predicted by docking studies. Hydrophobic and H-bond interactions were discovered to make key roles in the ligand-receptor bindings. Compared with the previous C7, several molecules such as D9, D14 and D15, exhibited significantly improved activities in inhibiting the growth of HL-60, ES-2, A549 and PLC cell lines.
Concise total synthesis of aplysinellamides A and B

, p. 336 - 339 (2015/08/11)
Concise and efficient total syntheses of bromotyrosine-derived metabolites aplysinellamides A and B, isolated from Australian marine sponge Aplysinella sp., have been accomplished in seven steps. A condensation between cinnamic acid and Boc-D-lysine methyl ester was applied to form the amide skeleton as a key step.
