Identification of inhibitors targeting polyketide synthase 13 of Mycobacterium tuberculosis as antituberculosis drug leads

Polyketide synthase 13 (Pks13) is an essential enzyme in the synthesis of mycolic acids in Mtb. Therefore, Pks13 is a promising drug target for tuberculosis treatment. We used a structure-guided approach to identify novel chemotype inhibitors of Pks13 and assessed them using a Pks13 enzymatic assay and surface plasmon resonance. The structure–activity relationships (SAR) results demonstrated that the substituents at the 2, 5, and 6 positions of the 4H-chromen-4-one scaffold are critical for maintaining the MIC. Compound 6e with 2-hydroxyphenyl at the 2 position of the 4H-chromen-4-one scaffold, exhibited potent activity against Mtb H37Rv (MIC = 0.45 μg/mL) and displayed good Pks13 affinity and inhibition (IC50 = 14.3 μM). This study described here could provide an avenue to explore a novel inhibitor class for Pks13 and aid the further development of antituberculosis drugs.

Synthesis and biological evaluations of chalcones, flavones and chromenes as farnesoid x receptor (FXR) antagonists

Farnesoid X receptor (FXR), a nuclear receptor mainly distributed in liver and intestine, has been regarded as a potential target for the treatment of various metabolic diseases, cancer and infectious diseases related to liver. Starting from two previously identified chalcone-based FXR antagonists, we tried to increase the activity through the design and synthesis of a library containing chalcones, flavones and chromenes, based on substitution manipulation and conformation (ring closure) restriction strategy. Many chalcones and four chromenes were identified as microM potent FXR antagonists, among which chromene 11c significantly decreased the plasma and hepatic triglyceride level in KKay mice.

(Aminoalkoxy)chromones. Selective ? Receptor Ligands

A series of (aminoalkoxy)chromones has been prepared, members of which bind potently (16-100 nM) at the ? binding site and bind weakly (>1000 nm) at the dopamine D2 receptor and 33 other receptors, second messenger systems, and ion channels.At
