Fe(II)- A nd 2-oxoglutarate (2OG)-dependent JumonjiC domain-containing histone demethylases (JmjC KDMs) are "epigenetic eraser" enzymes involved in the regulation of gene expression and are emerging drug targets in oncology. We screened a set of clinically used iron chelators and report that they potently inhibit JMJD2A (KDM4A) in vitro. Mode of action investigations revealed that one compound, deferasirox, is a bona fide active site-binding inhibitor as shown by kinetic and spectroscopic studies. Synthesis of derivatives with improved cell permeability resulted in significant upregulation of histone trimethylation and potent cancer cell growth inhibition. Deferasirox was also found to inhibit human 2OG-dependent hypoxia inducible factor prolyl hydroxylase activity. Therapeutic effects of clinically used deferasirox may thus involve transcriptional regulation through 2OG oxygenase inhibition. Deferasirox might provide a useful starting point for the development of novel anticancer drugs targeting 2OG oxygenases and a valuable tool compound for investigations of KDM function.
The indole skeleton-containing [...] steroidal saponin aglycone derivatives, its preparation method and application

Paragraph 0043; 0045, (2016/10/27)
The invention discloses an indole skeleton-containing dihydropyrazolhydroxamic acid steroid sapogenin derivative, and a preparation method and an application thereof. The structure of the indole skeleton-containing dihydropyrazolhydroxamic acid steroid sapogenin derivative is represented by formula VIII shown in the specification; and in the formula VIII, R1 is selected from H and CH3, R2 is selected from H and CH3, R3 is selected from H and F, and R4 is selected from H and CH3. The derivative has an obvious inhibition effect on human breast cancer cells (MCF-7), cervical carcinoma cells (HeLa), lung cancer cells (A549) and liver cancer cells (HepG2), has same or better cytotoxicity on human renal epithelial cells (293T) than positive control drug Celecoxib, and can be used to prepare antitumor drugs. The derivative has the advantages of good bioactivity, high selectivity, low toxicity and short residual life.
