Discovery of Sisunatovir (RV521), an Inhibitor of Respiratory Syncytial Virus Fusion

RV521 is an orally bioavailable inhibitor of respiratory syncytial virus (RSV) fusion that was identified after a lead optimization process based upon hits that originated from a physical property directed hit profiling exercise at Reviral. This exercise encompassed collaborations with a number of contract organizations with collaborative medicinal chemistry and virology during the optimization phase in addition to those utilized as the compound proceeded through preclinical and clinical evaluation. RV521 exhibited a mean IC50 of 1.2 nM against a panel of RSV A and B laboratory strains and clinical isolates with antiviral efficacy in the Balb/C mouse model of RSV infection. Oral bioavailability in preclinical species ranged from 42 to >100% with evidence of highly efficient penetration into lung tissue. In healthy adult human volunteers experimentally infected with RSV, a potent antiviral effect was observed with a significant reduction in viral load and symptoms compared to placebo.

Reactivity of spiroanthraceneoxazolidines with cyclopropanes: An approach to the oxindole alkaloid scaffold

The reaction of N-methylspiro[anthracene-oxazolidine] with spiro[cyclopropane-3,3′-indolin]-2-ones in the presence of MgI2 formed the corresponding spiro[pyrrolidine-3,3′-indolin]-2-ones in 42–65% yields. The use of N-benzylspiro[anthracene-oxazolidine] in this reaction led to the formation of a mixture of the corresponding N-methyl- and N-benzylpyrrolidines.

Domino Corey-Chaykovsky Reaction for One-Pot Access to Spirocyclopropyl Oxindoles

The development of the sequential Corey-Chaykovsky reactions of isatins, spiroepoxy-, or spiroaziridine oxindoles with sulfur ylide has led to the discovery of a unique reaction mode that allows easy and direct one-pot access to a range of spirocyclopropyl oxindoles.
