An efficient, direct and general synthesis of enantiopure γ-azido-tetrahydrofuran carboxylic acid monomers (5–8) from commercially available glycals, suitable to design peptidomimetic oligomers with predisposed conformation, is described. The single crystal X-ray study of 8 showed that the compound crystallized in orthorhombic space group. The crystal-packing showed the presence of weak intermolecular

A series of 2-alkylaminomethyl jaspine B analogues were synthesized and evaluated for their cytotoxic effects on human lung adenocarcinoma, breast cancer, and prostate cancer cell lines and a mouse melanoma cell line. Most of the compounds exhibited moderate to good activity against the cancer cell lines. Compound 7f showed the best overall cytotoxicity on PC-3 cells (IC50 = 0.85 mu M). Further mechanistic studies revealed that compound 7f induced marked changes in PC-3 cell morphology, disrupted the mitochondrial membrane potential, and increased expression of the autophagy proteins beclin-1, LC3, and P62.
