Design, synthesis, and molecular docking studies of N-(9,10-anthraquinone-2-carbonyl)amino acid derivatives as xanthine oxidase inhibitors

A series of N-(9,10-anthraquinone-2-carbonyl)amino acid derivatives (1a–j) was designed and synthesized as novel xanthine oxidase inhibitors. Among them, the L/D-phenylalanine derivatives (1d and 1i) and the L/D-tryptophan derivatives (1e and 1j) were effective with micromolar level potency. In particular, the L-phenylalanine derivative 1d (IC50?=?3.0?μm) and the D-phenylalanine derivative 1i (IC50?=?2.9?μm) presented the highest potency and were both more potent than the positive control allopurinol (IC50?=?8.1?μm). Preliminary SAR analysis pointed that an aromatic amino acid fragment, for example, phenylalanine or tryptophan, was essential for the inhibition; the D-amino acid derivative presented equal or greater potency compared to its L-enantiomer; and the 9,10-anthraquinone moiety was welcome for the inhibition. Molecular simulations provided rational binding models for compounds 1d and 1i in the xanthine oxidase active pocket. As a result, compounds 1d and 1i could be promising lead compounds for further investigation.

Synthesis of β-lactam peptidomimetics through Ugi MCR: First application of chiral Nβ-Fmoc amino alkyl isonitriles in MCRs

Chiral Nβ-Fmoc amino alkyl isonitriles were employed in Ugi multi component reactions (Ugi 4C-3CR) to obtain functionalized β-lactam peptidomimetics with l-aspartic acid α-methyl ester/peptide ester and organic aldehydes. The reactions were carried out in MeOH. Thirteen Ugi products have been prepared in good to moderate yields with good diastereoselectivities.
