Abstract:
The present invention relates to a method for producing quercetin 3,7-di-O-rhamnosidemade in plants using Escherichia coli, and more specifically, to metabolic-adjusted Escherichia coli and synthesis of quercetin 3,7-di-O-rhamnosideusing using the same.
Abstract:
A naringenin derivative is provided to be involved with controlling cell signal transmission, activity of activated oxygen species and cell cycle, thereby being widely used as a therapeutic agent of various cancers including large intestine cancer. A naringenin derivative controlling apoptosis is selected from the group consisting of 7-O-(m-methoxybenzyl) naringenin, 7-O-benzoxycarbonylmethyl naringenin, 7-O-benzylnaringenin, 7-O-(2-naphtylmethyl) naringenin, 7-O-(p-fluorobenzyl) naringenin and 7-O-(m-iodobenzyl) naringenin. A pharmaceutical composition for treating large intestine cancer comprises the naringenin derivative as an effective ingredient. A method for preparing the naringenin derivative comprises the steps of: (a) after putting naringenin and alkyl bromide in dimethylformamide, adding K2CO3 thereto and mixing it; (b) adding AcOEt to the mixture obtained from the step(a) and then dissolving it completely; (c) washing it with saline solution and drying; and (d) subjecting the product obtained from the step(c) to a silica gel chromatography for purifying it.
