Design, synthesis and biological evaluation of novel perimidine o-quinone derivatives as non-intercalative topoisomerase II catalytic inhibitors
摘要:
For the development of novel anticancer agents, we designed and synthesized a total of 37 perimidine o-quinone derivatives containing the o-quinone group at the A or B ring and different substituents (alkyl groups, aryl groups or heterocycles) at the C ring of the compounds. The structure-activity relationships (SARs) were established based on the cytotoxicity data of compounds from the HL-60, Huh7, Hct116, and Hela cell lines. The cytotoxicity results showed that most compounds exhibited potent cytotoxicity. In particular, compound b-12 showed the best anti-proliferative activity (IC50 <= 1 mu M) against four cancer cell lines and strong potency against the HL-60/MX2 (0.47 mu M) cell line, which is resistant to Topo II poisons. Further studies showed that b-12 exhibited potent Topo II alpha inhibitory activity (IC50 = 7.54 mu M) compared with Topo I, which acted as a class of non-intercalative Topo IIa catalytic inhibitor by inhibiting the ATP binding site of Topo II. Cell apoptosis and cell cycle assays confirmed that b-12 could induce the apoptosis of Huh7 cells in a dose-dependent manner.

The present invention relates to hydroxamate compounds and pharmaceutical compositions that are useful for treating and/or preventing metabolic inflammation mediated diseases such as diabetes, obesity, hypertension, dyslipidemia, a neurodegenerative disorder (e.g., Alzheimer's disease, Parkinson's disease, or Huntington's disease), or any combination thereof. Moreover, the present invention also provides methods of treatment for these diseases or disorders.
