variable loop region (V3loop) on gp120 plays an important role in cellular entry of HIV-1. Its interaction with the cellular CD4 and coreceptors is an important hallmark in facilitating the bridging by gp41 and subsequent fusion of membranes for transfer of viral genetic material. Further, the virus phenotype determines the cell tropism via respective co– receptor binding. Thus, coreceptor binding motif

The present invention relates to a compound of formula I wherein X is C(R6) or N, Y is C or N, and ring A, ring B, R1 and R2 have the meanings defined herein, provided that when ring B is carbocyclic, X is C(R6); or a pharmaceutically acceptable salt or solvate thereof. The compounds are tankyrase-1 and tankyrase-2 inhibitors and are useful in the treatment of a number of conditions, including cancer.
A simple and highly efficient synthesis of 2-substitutedquinazolin-4(3 H )-ones by the iron(III) chloride catalyzed reaction of isatoic anhydride with various amidoxime derivatives was developed. Several aryl and alkyl amidoximes were screened to demonstrate the scope of the methodology.

Tankyrases (TNKSs), members of the PARP (Poly(ADP-ribose)polymerases) superfamily of enzymes, have gained interest as therapeutic drug targets, especially as they are involved in the regulation of Wnt signalling. A series of 2-arylquinazolin-4-ones with varying substituents at the 8-position was synthesised. An 8-methyl group (compared to 8-H, 8-OMe, 8-OH), together with a 4′-hydrophobic or electron-withdrawing
Iron-catalyzed aerobic oxidativefunctionalization of sp3 C–Hbonds has been developed for the construction of N-heterocycles from easily available carboxylic acid derivatives and o-substituted anilines. This transformation represents a widely applicable protocol to N-heterocycles using biofriendly iron as a catalyst in combination with molecular oxygen or air as the sole oxidant.
