This invention relates to novel anthraquinone compounds useful in the treatment of allergic, inflammatory conditions, antioxidant, tumor condition, stem cell application, tissue engineering, applied in treating age-associate tissue degeneration, reverse organ failure in chronic high-turnover disease and therapeutic compositions containing such compounds. The compounds of the present invention are 1,4-, 1,5- and 1,8-difunctionalized anthraquinones or analogs thereof. According to the practice of the invention, there are provided bis-symmetrical substituted anthraquinone compounds according to formula I:
wherein R1, R2, R3 and R4 present a straight, aminoalkylamino side chains or branched chain alkyl group having 1 to 6 carbons which may be substituted with one or more groups of R5, or R1, R2, R3 and R4 present phenyl or benzyl which may be substituted with one or two groups of R6; wherein R5 is selected from the group consisting of halogen, —RNH

Chart 1. Activation of hTERT promoter-driven SEAP expression by c-Myc. About 1×10
7
hTERT-BJ1 cells were transfected with 13.5 μg each of plasmid pSEAP or pPhTERT-SEAP and of plasmid pMT2T or pMT2T-cMyc by electroporation. After 24 h, viable cells were harvested, and reinoculated at a density of 3×10
5
/mL, and the SEAP activity after 24 h at 37 □. The transfection efficiency of each experiment was determined by cotransfection with 1.5 μg of plasmid pCMVβ. The values were determined from three experiments. P<0.05 is presented by an asterisk.
