Benzoxaboroles, as a novel class of bioactive molecules with unique physicochemical properties, have been shown to possess excellent antimicrobial activities with tavaborole approved in 2014 as an antifungal drug. Although urgently needed, the investigation of benzoxaboroles as anticancer agents has been lacking so far. In this study, we report the design, synthesis, and anticancer structure-activity relationship of a series of 7-propanamide benzoxaboroles. Compounds 103 and 115 showed potent activity against ovarian cancer cells with IC50 values of 33 and 21 nM, respectively. Apoptosis was induced by these compounds and colony formation was effectively inhibited. Furthermore, they also showed excellent efficacy in ovarian tumor xenograft mouse model.

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.
Pd/mannose promoted tandem cross coupling-nitro reduction: Expedient synthesis of aminobiphenyls and aminostilbenes

The dual role of d-mannose as a ligand for Pd catalyzed cross-coupling, and as a hydrogen source for nitro reduction is demonstrated in a modular cross coupling-nitro reduction sequence. The synthetic utility and generality of this green protocol has been illustrated by the synthesis of 20 aminobiphenyl and 10 aminostilbene derivatives in high yields through a one-pot Suzuki coupling-nitro reduction and a Heck coupling-nitro reduction, respectively, starting from halonitroarenes as substrates.

Homogeneous Pd catalysts have been identified for the conversion of cyclohexenone and tetralone O-pivaloyl oximes to the corresponding primary anilines and 1-aminonaphthalenes. This method is inspired by the Semmler-Wolff reaction, a classic method that exhibits limited synthetic utility owing to its forcing conditions, narrow scope, and low product yields. The oxime N-O bond undergoes oxidative addition to Pd0(PCy3)2, and the product of this step has been characterized by X-ray crystallography and shown to undergo dehydrogenation to afford the aniline product.
