Design, synthesis and biological evaluation of amino acids-oleanolic acid conjugates as influenza virus inhibitors

Viral entry inhibitors are of great importance in current efforts to develop a new generation of anti-influenza drugs. Inspired by the discovery of a series of pentacyclic triterpene derivatives as entry inhibitors targeting the HA protein of influenza vi

Oleanolic acid and its derivatives: New inhibitor of protein tyrosine phosphatase 1B with cellular activities

Protein tyrosine phosphatase 1B is a key factor in the negative regulation of insulin pathway and a promising target for treatment of diabetes and obesity. Herein, a series of competitive inhibitors were optimized from oleanolic acid, a natural triterpenoid identified against PTP1B by screening libraries of traditional Chinese medicinal herbs. Modifying at 3 and 28 positions, we obtained compound 13 with a Ki of 130 nM, which exhibited good selectivity between other phosphatases involved in insulin pathway except T-cell protein tyrosine phosphatase. Further evaluation in cell models illustrated that the derivatives enhanced insulin receptor phosphorylation in CHO/hIR cells and also stimulated glucose uptake in L6 myotubes with or addition of without insulin.

Synthesis and activity of oleanolic acid derivatives, a novel class of inhibitors of osteoclast formation

Two series of oleanolic acid derivatives were synthesized and their inhibitory activity on the formation of osteoclast-like multinucleated cells (OCLs) induced by 1α,25-dihydroxy vitamin D3 was evaluated in a co-culture assay system. The structure-activity relationships, together with electronic structure based on the frontier molecular orbitals, for example, HOMO and LUMO, related to different amino acid substituents were studied. Derivatives with proline or phenylalanine showed a tendency to enhance the inhibitory activity.
