-
Page/Page column 76; 77, (2014/10/15)
The present invention provides aminohydantoin anti-malarial agents. In some embodiments, these agents have the property of functions of targeting malarial aspartic proteases while at the same time having low activity against human BACE. Methods of employing such agents are also provided.

A new series of polycyclic aromatic hydrocarbons (PAHs) with different peripheries was synthesized via oxidative cyclodehydrogenation of suitable oligophenylene precursors under mild conditions. Such large PAHs are considered to be two-dimensional graphite sections whose electronic properties are expected to converge to those of macroscopic graphite. The synthetic buildup of the oligophenylene frameworks was mainly based either on Diels-Alder reactions or on cyclotrimerizations. They were subsequently converted into planar aromatic hydrocarbons containing up to 78 carbon atoms. Due to the insufficient solubility of extended PAHs, characterization was achieved by laser desorption/ionization time-of-flight mass spectrometry and UV/visible spectroscopy of thin films.

A large number of 7,9-disubstituted derivatives (I) of cyclopentacenaphthylene-8(H)-one and 2,5-disubstituted derivatives (II) of 3,4-diphenylcyclopentadienone have been synthesized by condensing acenaphthaquinone and benzil separately with suitable 1,3-disubstituted propan-2-ones.The 3-(o- and p-methoxytolyl)cyclopentadienones (IX) have been synthesized by Friedel-Crafts reaction of appropriate methyl cresyl ethers and phenacyl chloride.These dienones have been subjected to Diels-Alder reaction with acenaphthylene and a new acetylenic dienophile (V) (whose synthesis is also described in this paper) to yield a large number of polynuclear aromatic compounds having fluoranthene and p-quaterphenyl nuclei, which have been finally characterised by elemental analyses, IR and PMR spectral data.
