the indoloquinoline alkaloids quindoline and cryptolepine. The facile removal of the Boc protecting group was the key to the success of the syntheses. The scope of the reaction was extended to a C(sp3)Hbond amination and to the amination of 2‐phenyloxazoline. For the amination of 2‐pyridin‐2‐ylbenzene a kinetic deuterium isotope effect of 2.0 was determined.
Substituted phenyl, naphthyl, and thienyl N-hydroxy urea compounds form a class of potent inhibitors of 5- and 12-lipoxygenase and are thus useful compounds in the treatment of inflammatory disease states where leukotrienes and other products of lipoxygenase enzyme activity are implicated.
react with copperchloride to give compounds of formulae [Cu(pyth) 2 Cl 2 ] ( I ) and [Cu(apyth) 2 Cl 2 ] ( II ). The crystalstructures of I , II and III have been determined by X-ray methods. In both copper complexes the metal atom is surrounded by two N atoms (CuN, 2.025(5) A in I and 2.021(2) A in II ) from two ligands molecules and two Cl atoms (2.265(2) A in I and 2.264(1) A in II ) in a typical
The present invention relates to novel Triheterocyclic Compounds, compositions comprising a Triheterocyclic Compound, and methods useful for treating or preventing cancer or a neoplastic disorder comprising administering a Triheterocyclic Compound. The compounds, compositions, and methods of the invention are also useful for inhibiting the growth of a cancer cell or neoplastic cell, treating or preventing a viral infection, or inhibiting the replication and/or infectivity of a virus.
