- Novel Aryl-Substituted Pyrimidones as Inhibitors of 3-Mercaptopyruvate Sulfurtransferase with Antiproliferative Efficacy in Colon Cancer
-
The enzyme 3-mercaptopyruvate sulfurtransferase (3-MST) is one of the more recently identified mammalian sources of H2S. A recent study identified several novel 3-MST inhibitors with micromolar potency. Among those, (2-[(4-hydroxy-6-methylpyrimidin-2-yl)sulfanyl]-1-(naphthalen-1-yl)ethan-1-one) or HMPSNE was found to be the most potent and selective. We now took the central core of this compound and modified the pyrimidone and the arylketone sides independently. A 63-compound library was synthesized; compounds were tested for H2S generation from recombinant 3-MST in vitro. Active compounds were subsequently tested to elucidate their potency and selectivity. Computer modeling studies have delineated some of the key structural features necessary for binding to the 3-MST's active site. Six novel 3-MST inhibitors were tested in cell-based assays: they exerted inhibitory effects in murine MC38 and CT26 colon cancer cell proliferation; the antiproliferative effect of the compound with the highest potency and best cell-based activity (1b) was also confirmed on the growth of MC38 tumors in mice.

- Acid Catalysed Prototropy of Substituted Acetonaphthones - Kinetics of Perchloric Acid Catalysed Bromination and Phenyl Iodosoacetate Oxidation
-
Enolisation rates of several 4-substituted 1-acetonaphthones and 6-substituted 2-acetonaphthones at three different temperatures in acetic acid-water mixture (95percent, v/v) in perchloric acid catalysed bromination and phenyl iodosoacetate (PIA) oxidation reactions correlate very well with Hammett ?p constants.Acetonaphthones with 4- and 6-OCH3 substituents deviate from the corresponding Hammett plot for PIA oxidation.From basicity data deprotonation rate constants (kd) have been evaluated for bromination and PIA oxidation reactions.
