- α-Glucosidase inhibition of 6-hydroxyflavones. Part 3: Synthesis and evaluation of 2,3,4-trihydroxybenzoyl-containing flavonoid analogs and 6-aminoflavones as α-glucosidase inhibitors
-
The SAR studies suggested that the C-ring of baicalein (1) was not necessary for the activity, and validated the importance of 2,3,4- trihydroxybenzoyl structure of 1. Thus, a series of 2,3,4-trihydroxybenzoyl- containing flavonoid analogs were investigat

- REACTIVITY OF ARYLCINNAMATES IN POLYPHOSPHORIC ACID (PPA): CYCLISATION AND REARRANGEMENT REACTIONS
-
In polyphosphoric acid (PPA), various phenyl-substituted cinnamates react to give 4-phenyl-3,4-dihydrocoumarins, flavanones or 3-phenylindanone owing to the nature of the substituents on the phenyl moiety.

- FLAVONONE AND OTHER CONSTITUENTS FROM ONYCHIUM SILICULOSUM
-
Key Word Index - Onychium siliculosum; Pteridaceae; pterosins; flavonones; structure elucidation. Two new compounds, onitinoside and onysilin along with the known compounds, pinostrobin, onitin, onitisin, campesterol, sitosterol and n-alkanes (C25-C33) were isolated from Onychium siliculosum.Onitinoside and onysilin were identified by spectral and chemical methods as 4-O-glucosyl-6-(2'-hydroxyethyl)-2,2,5,7-tetramethylindan-1-one and 5-hydroxy-6,7-dimethoxyflavonone, respectively.
