Patent: WO2021207711 A2 | Chadwick, Alexandra et al. published a patent in 2021| cas: 550-33-4

(2R,3S,4R,5R)-2-(Hydroxymethyl)-5-(9H-purin-9-yl)tetrahydrofuran-3,4-diol (cas: 550-33-4) belongs to tetrahydrofuran derivatives.Tetrahydrofuran has many industry uses as a solvent including in natural and synthetic resins, high polymers, fat oils, rubber, polymer. Tetrahydrofuran reaction with hydrogen sulfide: In the presence of a solid acid catalyst, tetrahydrofuran reacts with hydrogen sulfide to give tetrahydrothiophene.Product Details of 550-33-4

Chemically modified guide RNAs for genome editing with Cas9 was written by Chadwick, Alexandra; Rajeev, Kallanthottathil G.; Rohde, Ellen; Cheng, Christopher; Reiss, Caroline. And the patent was published on October 14,2021.Product Details of 550-33-4 The following contents are mentioned in the patent:

Provided herein are compositions for gene modification or editing and methods of using same to treat or prevent certain conditions. Specific compositions and methods capable of safely and effectively editing PCSK9 and ANGPTL3 gene targets expressed in the liver to durably lower LDL-C thereby treating a leading cause of cardiovascular disease are disclosed. This study involved multiple reactions and reactants, such as (2R,3S,4R,5R)-2-(Hydroxymethyl)-5-(9H-purin-9-yl)tetrahydrofuran-3,4-diol (cas: 550-33-4Product Details of 550-33-4).
