Human immunodeficiency virus (HIV) reverse transcriptase (RT) associated ribonuclease H (RNase H) remains an unvalidated antiviral target. A major challenge of specifically targeting HIV RNase H arises from the general lack of selectivity over RT polymerase (pol) and integrase (IN) strand transfer (ST) inhibitions. We report herein the synthesis and biochemical evaluations of three novel 3-hydroxypyrimidine-2,4-dione (HPD) subtypes carefully designed to achieve selective RNase H inhibition. Biochemical studies showed the two subtypes with an N-1 methyl group (9 and 10) inhibited RNase H in low micromolar range without siginificantly inhibiting RT polymerase, whereas the N-1 unsubstituted subtype 11 inhibited RNase H in submicromolar range and RT polymerase in low micromolar range. Subtype 11 also exhibited substantially reduced inhibition in the HIV-1 INST assay and no significant cytotoxicity in the cell viability assay, suggesting that it may be amenable to further structure-activity relationship (SAR) for identifying RNase H inhibitors with antiviral activity.

Necroptosis inducers represent a promising potential treatment for drug-resistant cancer. We herein describe the structure modification of E6, which was identified recently as a potent and selective necroptosis inducer. The studies described herein demonstrate for the first time that functionalized biphenyl derivatives possess necroptosis inducer activity. Furthermore, these studies have led to the identification of two promising compounds (5h and 5j) that can be used for further optimization studies as well as mechanism of action investigations.
Facile synthesis of mono-, bis- and tris-aryl-substituted aniline derivatives in aqueous DMF

A facile, efficient and general protocol for synthesizing a series of mono-, bis- and tris-arylsubstituted aniline derivatives is described via the Pd(OAc)2-catalyzed aerobic and ligand-free Suzuki reaction of mono-, di- and tribromoanilines with aryl boronic acids in aqueous N,Ndimethylformamide (DMF). This is the first example to prepare 2,6-bisaryl-4-nitroanilines and 2,6-bisarylanilines via a palladium-catalyzed ligand-free Suzuki reaction.
