Anti-inflammatory and anti-allergy extracts from nettle was written by Alberte, Randall S.; Roschek, William P., Jr.; Li, Dan. And the patent was published on January 14,2010.Electric Literature of C10H12N4O4 The following contents are mentioned in the patent:
The present invention relates in part to nettle extracts comprising at least one compound useful for treating or preventing seasonal allergies, allergic rhinitis, and other inflammatory conditions. The nettle extracts showed inhibitory activities against COX-1, COX-2, 5-lipoxygenase, and tryptase, as well as H1 antagonistic activity. 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: 550-33-4Electric Literature of C10H12N4O4 ).
(2R,3S,4R,5R)-2-(Hydroxymethyl)-5-(9H-purin-9-yl)tetrahydrofuran-3,4-diol (cas: 550-33-4) belongs to tetrahydrofuran derivatives. Solid acid catalysis, and the advantages often associated with their use, have been proved equally efficient for the synthesis of tetrahydrofurans or furans. Tetrahydrofuran (THF) is primarily used as a precursor to polymers including for surface coating, adhesives, and printing inks.Electric Literature of C10H12N4O4
