Optimization of 5-arylidene barbiturates as potent, selective, reversible LSD1 inhibitors for the treatment of acute promyelocytic leukemia

Histone lysine specific demethylase 1 (LSD1) is overexpressed in diverse hematologic disorders and recognized as a promising target for blood medicines. In this study, molecular docking-based virtual screening united with bioevaluation was utilized to identify novel skeleton of 5-arylidene barbiturate as small-molecule inhibitors of LSD1. Among the synthesized derivatives, 12a exhibited reversible and potent inhibition (IC50 = 0.41 μM) and high selectivity over the MAO-A and MAO-B. Notably, 12a strongly induced differentiation effect on acute promyelocytic leukemia NB4 cell line and distinctly escalated the methylation level on histone 3 lysine 4 (H3K4). Our findings indicate that 5-arylidene barbiturate may represent a new skeleton of LSD1 inhibitors and 12a deserve as a promising agent for the further research.

Composition for trichogenousness

The present invention relates to novel barbiturate and thiobarbiturate derivatives and a composition for promoting hair growth using the same. According to the present invention, the barbiturate and thiobarbiturate derivatives, in an animal model, have shown to promote hair growth and have excellent effects on hair growth by promoting regulation of Wnt/andbeta;-catenin and hair growth factor signaling and suppressing mechanism of apoptosis. Accordingly, the barbiturate and thiobarbiturate derivatives of the present invention may be used as a composition for promoting hair growth.COPYRIGHT KIPO 2017

Synthesis and antitumor evaluation of novel cyclic arylsulfonylureas: ADME-T and pharmacophore prediction

Novel derivatives of 5-(substituted)benzylidene-3-(4-substituted)phenylsulfonylimidazolidine-2,4-diones (3a-r), 1-(4-substituted)phenylsulfonyl-3-(4-substituted)phenylpyrimidine-2,4,6-(1H,3H,5H)-triones (6a-l), and 3-(4-substituted)phenyl-1-(4-substituted)phenylsulfonylquinazoline-2,4(1H,3H)- diones (8a-l) have been synthesized and tested for their antitumor activity against 60 tumor cell lines taken from 9 different organs. The tested compounds have showed good inhibitory effect at the ovarian cancer (IGROV1) cell line. A significant inhibition for (RXF393) renal cancer cells was observed with series 3 compounds, while in the other two series 6 and 8, there was a significant inhibition of ovarian cancer cells (OVCAR-8) and melanoma cells (SK-MEL-2). Interestingly; beside the strong inhibition of compound 3q to IGROV1 and RXF393 cells, a great inhibition (199.62%) for (M14) Melanoma cells was observed at the tested concentration (10?μM). ADME-T and pharmacophore prediction methodology were used to study the antitumor activity of the most active compounds and to identify the structural features required for antitumor activity.

Synthesis of novel galactopyranosyl-derived spiro barbiturates

Malonic acid undergoes condensation readily with ureas to yield barbituric acids 2, which on bromination give 5,5-dibromobarbituric acids 3. Reaction of α-D-galactose with these 5,5-dibromo barbituric acids afforded 2,3-α-D-galactopyrano-1,4-dioxo-7,9-diaza-spiro[4,5]deca-6,8,10-triones 4. The structures of the products have been assigned on the basis of 1H NMR, 13C NMR, FAB-MS, optical activity, and elemental analysis. The title compounds are found to have antibacterial and antifungal activities.

Chemical modification of plant alkaloids. 2. Reaction of cotarnine with barbituric acid derivatives and structure of 5-dihydrocotarnylbarbituric acids

The reaction of barbituric acid and its N-substituted derivatives and 2-thio analogs with cotarnine forms 5-(4-methoxy-6-methyl-5,6,7,8-tetrahydro-2H-1,3-methylenedioxy-[4,5-g]isoquinolinyl-1)barbituric acids, a new class of zwitter-ions, the structure of which was studied by 1H and 13C NMR spectroscopy and mass spectrometry. The prepared compounds exist in solution as stable intermolecular associates and have a complicated H-bonded structure.
