Low Molecular Weight Amidoximes that Act as Potent Inhibitors of Lysine-Specific Demethylase 1
摘要:
The recently discovered enzyme lysine-specific demethylase 1 (LSD1) plays an important role in the epigenetic control of gene expression, and aberrant gene silencing secondary to LSD1 dysregulation is thought to contribute to the development of cancer. We reported that (bis)guanidines, (bis)biguanides, and their urea- and thiourea isosteres are potent inhibitors of LSD1 and induce the re-expression of aberrantly silenced tumor suppressor genes in tumor cells in vitro. We now report a series of small molecule amidoximes that are moderate inhibitors of recombinant LSD1 but that produce dramatic changes in methylation at the histone 3 lysine 4 (H3K4) chromatin mark, a specific target of LSD1, in Calu-6 lung carcinoma cells. In addition, these analogues increase cellular levels of secreted frizzle-related protein (SFRP) 2, H-cadherin (HCAD), and the transcription factor GATA4. These compounds represent leads for an important new series of drug-like epigenetic modulators with the potential for use as antitumor agents.
crystallographic study of AKR1C3 complexes with 2j and 2l. The inhibitorssuppressedproliferation of prostatecancer 22Rv1 and PC3 cells through both androgen-dependent and androgen-independent mechanisms. Additionally, 2j and 2l prevented prostatetumorgrowth in a xenograftmousemodel. Furthermore, the inhibitors significantly augmented apoptotic cell death induced by anti-CRPC drugs (abiraterone or enzalutamide)

been synthesized. Their in vivo biological activity determined in rat and mouse delayed type hypersensitivity has been found to correlate well with their in vitro DHODH potency. The most promising compound (3) has shown activity in rat and mouse collagen (II)-induced arthritis models (ED50 = 2 and 31 mg/kg, respectively) and has shown a shorter half-life in man when compared with leflunomide.

A series of alpha-cyano-beta-hydroxypropenamides was prepared and tested for anthelmintic activity. Alpha-cyano-beta-hydroxy hydroxy-N-[4-(trifluoromethyl)phenyl]-3-[4-(trifluoromethyl)phenyl]propenamide (1) showed good activity against the nematode Nematospirodes dubius in a mixed parasite infection in mice; several of the analogues were also effective against the cestode Hymenolepis nana. In sheep trials, 1 caused 100% reduction of the hematophagous nematode Haemonchus contortus after a single dose of 20 mg/kg but did not show satisfactory control of Trichostrongylus colubriformis or Ostertagia circumcincta. Against the liver fluke Fasciola hepatica, 1 suppressed egg production but only temporarily, suggesting that the adult flukes were not eliminated. Mechanism of action studies on 1 using Ascaris mitochondria showed it to be an uncoupler of oxidative phosphorylation.
