    摘要: Telomere is the nucleoprotein structture at the end of eukaryotic chromosomes, and functional telomeres are essential for continued cell proliferation. Because of the end replication problem, telomere is shortened by 50-60 bases whenever cell division happens, and this erosion induces apoptosis when its length became critically short The enzyme telomerase is able to perform this function of length extension, since it is a specialized reverse transcriptase with an endogenous RNA template on which successive telomeric repeats are synthesized. Most human tumors not only express telomerase but also have very short telomeres, whereas telomerase activity is either reduced or absent in normal tissues, making the inhibition of telomerase an attractive target for cancer therapeutics. In the recent research shown that inhibition of telomerase can be achieved with appropriately planar aromatic structure such as anthraquinone derivatives. This inhibibition is believed to occur as a result of the stabilization of telomeric DNA by these compounds as folded G-quadruplex structurejres. A series of anthra[l,2-d]imidazole-6,l 1-dione derivatives were synthesized which will be evaluated for their effects by TRAP assay, cell proliferations and cytotoxicity by MTT assay, hTERT expression by SEAP assay.
