Paragraph 0101; 0102-0104, (2018/10/19)
The present invention discloses a five-membered heterocyclic amide WNT pathway inhibitor, which belongs to a compound that regulates the activity of a Wnt signaling pathway, and provides a method for preparing such a compound, and the use of such a compound in preparing a medicament that antagonizes the Wnt signaling pathway. The five-membered heterocyclic amide WNT pathway inhibitor provided by the invention has a remarkable anti-tumor activity based on a target-based rational drug design of, and can be used for the development of a new generation of Wnt pathway inhibitors, and has a great clinical application value and considerable market potential.

Overexpression of efflux pumps is an important mechanism of bacterial resistance that results in the extrusion of antimicrobial agents outside the bacterial cell. Inhibition of such pumps appears to be a promising strategy that could restore the potency of existing antibiotics. The NorA efflux pump of Staphylococcus aureus confers resistance to a wide range of unrelated substrates, such as hydrophilic fluoroquinolones, leading to a multidrug-resistance phenotype. In this work, approximately 150 heterocyclic boronic species were evaluated for their activity against susceptible and resistant strains of S. aureus. Twenty-four hit compounds, although inactive when tested alone, were found to potentiate ciprofloxacin activity by a 4-fold increase at concentrations ranging from 0.5 to 8 μg/mL against S. aureus 1199B, which overexpresses NorA. Boron-free analogues showed no biological activity, thus revealing that the boron atom is crucial for biological activity. This work describes the first reported efflux pump inhibitory activity of boronic acid derivatives.
