The alpha-fetoprotein is isolated from placenta or umbilical cord extracts. The extract of placenta or umbilical cord is obtain by homogenizeration. An antioxidative composition contains alpha-fetoprotein as an active ingredient.
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.
Abstract:
An mRNA binding protein XaiF(xylanase activity increasing factor) is provided to increase the activity of xylanase by being expressed simultaneously with an xyn A, increase the transcription of exogenous genes when being used with a stem-loop structure where it is attached and a strong promoter, and inhibit the decomposition of transcript, thereby being usefully used for mass-producing exogenous proteins. A stem-loop structure where XaiF as an mRNA binding protein is attached consists of a sequence of SEQ ID : NO. 3 and is used for controlling the expression of a foreign gene. A cloning vector comprises the stem-loop structure. To over-express an exogenous protein, the XaiF as the mRNA binding protein and the stem-loop structure are used, wherein the mRNA binding protein combines the stem-loop structure with a strong gene promoter including a T7 promoter.
Abstract:
5,7,3',4'-Tetrahydoxy flavanone having protective effects on the UV(ultraviolet)-induced cell death in human keratinocytes is provided to inhibit apoptosis of human keratinocytes caused by UV by inhibiting production of reactive oxygen species due to UV in cells and activity reduction of p38 MAP(mitogen-activated protein) kinase through treating the human skin exposed to UV with the flavonoide. A composition for inhibiting apoptosis of human keratinocytes caused by UV comprises the 5,7,3',4'-tetrahydoxy flavanone represented by the formula(1) and isolated from the plant such as Viscum album var. as an effective ingredient, wherein the composition is a cosmetic or pharmaceutical composition and is formulated as granule, tablet, capsule, drink, cream or lotion. The daily dosage of 5,7,3',4'-tetrahydoxy flavanone is 0.1-1000 mg per adult.
