As the insulin and leptin signaling pathway can be regulated by PTP1B, it has been suggested that compounds that reduce PTP1B activity or expression levels can be used for treating type 2 diabetes and obesity. In the course of our screening efforts on new PTP1B inhibitors, six new flavanones ( 1- 6)
In the course of our program to search for protein tyrosine phosphatase 1B (PTPB) inhibitors, five new 5-deoxyflavonoids along with eight known derivatives were isolated from EtOAc layer of the root bark of Erythrina abyssinica. Their structures were elucidated on the basis of spectroscopic (IR, UV,
Bioassay-guided fractionation of the EtOAc extract of the stem bark of Erythrina abyssinica (Leguminosae) resulted in the isolation of three new (1-3), along with 12 known (4-15) pterocarpan derivatives. Their chemical structures were determined by physicochemical and spectroscopic data analysis
