Abstract:
The present invention relates to flavonoid derivatives selectively inhibiting an activity of janus kinase 3, a method for manufacturing the same, and a use of the compound as immunosuppressive agents. The compound can be used as a safe immunosuppressive agent since the compound does not cause problems like pernicious anemia which is a side effect of a conventional immunosuppressant using JAK3 inhibitors.

Abstract:
PURPOSE: A SARS coronavirus helicase and/or composition for suppressing SARS coronavirus helicase containing aryl diketoacid(ADK) are/is provided to suppress DNA double strand unwinding of SARS coronavirus helicase. CONSTITUTION: An inhibitor of DNA double strand unwinding of SARS coronavirus helicase contains a compound of chemical formula 1 and its pharmaceutically acceptable salt. In chemical formula 1, R1 is hydrogen, R2-R5 are independently hydrogen, or R6-(CH2)n-R7, R6 is O or NH, n IS 1-3 integer, and R7 is phenyl or one or more halogen-substituted phenyl. A composition for suppressing SARS coronavirus contains the compound of chemical formula 1 and its pharmaceutically acceptable salt as active ingredient. Daily dose for an adult is 1mg to 1000mg once to several times a day. The composition is administered within 24 hours after coronavirus exporsrure.
Abstract:
A method for preparing an unsaturated ketone and derivatives thereof having an anticancer effect is provided to realize a high reaction rate by using a hydrophilic solvent, to allow selective and effective introduction of different substituents, and to enable mass production of target compounds. A method for preparing an unsaturated ketone compound and derivatives thereof having and anticancer effect and represented by the following formula 1, comprises the steps of: (1) providing hydroxyethyl methylvinyl ketone represented by the following formula 3 from methyl vinyl ketone and acetaldehyde through Baylis-Hillman mechanism; and (2) converting the resultant secondary alcohol(formula 3) into an acetate compound(formula 4), and carrying out 1,4-addition of phenyl Grignard reagent in the presence of copper iodide to obtain (E)-3-benzyl-3-penten-2-one(formula 2) as a main intermediate for the target compound.
