  • Publication number: 20230280220
    Abstract: The invention relates to benzimidazoles of Formula (1) and pharmaceutically acceptable salts thereof, wherein R1 to R6 are as defined in the description; to their use in medicine; to compositions containing them; to processes for their preparation; and to intermediates used in such processes. The benzimidazoles of Formula (1) are ITK inhibitors and are therefore potentially useful in the treatment of a wide range of disorders including, atopic dermatitis.

  • Patent number: 11597927
    Abstract: Among other things, the present disclosure provides designed PNPLA3 oligonucleotides, compositions, and methods thereof. In some embodiments, provided oligonucleotide compositions provide improved single-stranded RNA interference and/or RNase H-mediated knockdown. Among other things, the present disclosure encompasses the recognition that structural elements of oligonucleotides, such as base sequence, chemical modifications (e.g., modifications of sugar, base, and/or internucleotidic linkages) or N patterns thereof, conjugation with additional chemical moieties, and/or stereochemistry [e.g., stereochemistry of backbone chiral centers (chiral internucleotidic linkages)], and/or patterns thereof, can have significant impact on oligonucleotide properties and activities, e.g., RNA interference (RNAi) activity, stability, delivery, etc.
