-
, (2021/06/22)
Various embodiments provide STOPS? polymers that are S-antigen transport inhibiting oligonucleotide polymers, processes for making them and methods of using them to treat diseases and conditions. In some embodiments the STOPS? modified oligonucleotides include an at least partially phosphorothioated sequence of alternating A and C units having modifications as described herein. The sequence independent antiviral activity against hepatitis B of embodiments of STOPS? modified oligonucleotides, as determined by HBsAg Secretion Assay, is an EC50 that is less than 100 nM.

Fluorinated nucleoside 1 is a key starting material in the synthesis of rovafovir etalafenamide (2), a novel nucleotide reverse transcriptase inhibitor under development at Gilead Sciences for the treatment of HIV. While an initial manufacturing route enabled the production of 1 to support clinical development, alternative approaches were explored to further enhance manufacturing effectiveness, improve processing time, reduce cost, and minimize the environmental impact. Toward this end, two new routes were developed to a key synthetic intermediate, which was converted to 1 using a new protecting group strategy. The new chemistry led to improvements in the manufacturing process while reducing the overall process mass intensity (PMI).
