From the dried body of N. naja, inosine (I) [58-63-9] was isolated as 1 of the 3 hypotensive compounds after Sephadex G-25 chromatog. and purification by preparative HPLC. Hypotensive activity was observed at dose levels higher than 0.5 mg/kg, the activity strongly increasing with increasing I dose. However, at 0.1 and 0.25 mg/kg, I showed only a transient effect and the blood pressure recovered to the original level within one min. 2′-Deoxyinosine [890-38-0] and 3′-deoxyinosine [13146-72-0] completely lacked hypotensive activity. Phosphorylation at the 3′- or 5′-position of the ribose moiety slightly decreased the hypotensive activity. However, inosine 5′-diphosphoribose [86-04-4] showed the most potent hypotensive activity among compounds tested. Hydroxyl groups at C-2′ and C-3′ are necessary for I to show the activity. The importance of the ribose configuration of the sugar moiety of I for the hypotensive activity was demonstrated. This study involved multiple reactions and reactants, such as 9-((2R,3R,5S)-3-Hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-9H-purin-6-ol (cas: 13146-72-0Computed Properties of C10H12N4O4 ).
9-((2R,3R,5S)-3-Hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-9H-purin-6-ol (cas: 13146-72-0) belongs to tetrahydrofuran derivatives. Tetrahydrofuran (THF) is a Lewis base that bonds to a variety of Lewis acids such as I2, phenols, triethylaluminum and bis(hexafluoroacetylacetonato)copper(II). Commercial tetrahydrofuran contains substantial water that must be removed for sensitive operations, e.g. those involving organometallic compounds. Although tetrahydrofuran is traditionally dried by distillation from an aggressive desiccant, molecular sieves are superior.Computed Properties of C10H12N4O4
