Patent ID: 7727965

Claim:
A C-Glycosylisoflavone compound of the formula (I) having alkylaminoalkoxyl substituent or a pharmaceutically acceptable salt thereof: wherein, R 1 and R 2 are independently selected from the group consisting of hydrogen, (C 1 -C 12 ) linear or branched alkylamino (C 1 -C 6 )alkyl, mono- or di-(C 3-8 )cycloalkylamino-C 1-6 alkyl, and (C 5 -C 14 )heterocyclic-(C 1 -C 6 )alkyl; R 3 is selected from the group consisting of hydrogen, (C 1 -C 12 ) linear or branched acyl and C 6-14 aryl carbonyl; wherein R 1 and R 2 do not represent hydrogen simultaneously; the 1-position of D-glucosyl is connected with the 8-position of the isoflavone in a form of β-configured C-glycoside, wherein the mono- or di-(C 3-8 ) cycloalkylamino group of the mono- or di-(C 3-8 )cycloalkylamino-C 1-6 alkyl includes pyrrolidinyl and morpholinyl, and the (C 5 -C 14 )heterocyclic group of the (C 5 -C 14 )heterocyclic-(C 1 -C 6 )alkyl is selected from the group consisting of piperidyl, piperazinyl, N-methylpiperazinyl, and N-ethylpiperazinyl.
