Therapeutic effect of two transition metal coordination polymers on ovarian cancer by regulating the expression of estrogen receptor

In the present study, via using a ligand featuring oxalamide groups N,N′-bis(4-phthalic acid) (H(4)L), two new Cu(II) and Co(II)-containing coordination polymers with the chemical formulae of [Cu(2)L(H(2)O)(4)](n) (1) and [Co(H(2)L)(H(2)O)(2)](n) (2) have been successfully prepared via reaction of the corresponding metal salts with the H(4)L ligand. The as-prepared two coordination polymers have been studied via the single crystal X-ray diffraction, elemental analysis, powder X-ray diffraction and thermogravimetric analysis. Their therapeutic effect and mechanism for ovarian cancer was evaluated and explored. Firstly, the inhibitory activity of the new compounds on the proliferation of the ovarian cancer was measured with CCK-8 assay after compound treatment. Besides, the relative expression of the estrogen receptor on the ovarian cancer cells after compound treatment was also determined with real-time RT-PCR assay.
