英文摘要 | A chemical investigation of the twigs and leaves of Erythrina subumbrans led to the isolation and structural elucidation of three coumaronochromones, erythrinasubumbrin A and (+/-)-erythrinasubumbrin B, five preny-lated flavanones, (+/-)-erythrinasubumbrin C and erythrinasubumbrins D-F, and two prenylated isoflavones, (+/-)-5,4'-dihydroxy-[4,5-cis-4-ethoxy-5-hydroxy-6,6-dimethyl-4,5-dihydropyrano (2,3:7,6)]-isoflavone, in addi-tion to 18 known analogues. Two extra cinnamylphenols previously only known as commercial synthetic products were also isolated and elucidated from a natural source for the first time, and assigned the trivial names erythrinasubumbrins G and H. Their structures were characterized by detailed analysis of spectroscopic data, including HRESIMS and 2D NMR. The absolute configurations of the previously undescribed isolates and the known coumaronochromone lupinol C were determined by specific rotation and electronic circular dichroism (ECD) data. All the isolates were evaluated for their inhibitory activities on protein tyrosine phosphatase 1 B (PTP1B) and nitric oxide (NO) production in lipopolysaccharide (LPS)-induced BV-2 microglial cells as well as their cytotoxicity against the HCT116 cell line. The pair of enantiomers, (+)-5,4'-dihydroxy-[4,5-cis-4-ethoxy-5-hydroxy-6,6-dimethyl-4,5-dihydropyrano (2,3:7,6)]-isoflavone and (-)-5,4'-dihydroxy-[4,5-cis-4-ethoxy-5-hy-droxy-6,6-dimethyl-4,5-dihydropyrano (2,3:7,6)]-isoflavone, and the known compounds lupinol C, 4'-O-methyl-8-prenylnaringenin, glepidotin B, shuterin, parvisoflavones A, luteone, lupiwighteone, 2,3-dehydrokievitone, 6,8-diprenylgenistein, angustone A, and 2'-O-demethylbidwillol B exhibited different levels of PTP1B inhibi-tory activities with IC50 values ranging from 3.21 to 19.17 mu M, while erythrinasubumbrin A, (-)-eryth-rinasubumbrin B, (+)-5,4'-dihydroxy-[4,5-cis-4-ethoxy-5-hydroxy-6,6-dimethyl-4,5-dihydropyrano (2,3:7,6)]-isoflavone, (-)-5,4'-dihydroxy-[4,5-cis-4-ethoxy-5-hydroxy-6,6-dimethyl-4,5-dihydropyrano (2,3:7,6)]-isofla-vone, and the known compounds lupinol C, 8-prenylnaringenin, macatrichocarpin A, alpinumisoflavone, and 2'-O-demethylbidwillol B substantially inhibited NO production in BV-2 microglial cells. In addition, 8-prenylnar-ingenin showed weak cytotoxicity with an IC50 value of 9.13 mu M. This is the first report of PTP1B inhibitory activity for a coumaronochromone. |
