Triterpenes and Phenolic Compounds from Euphorbia deightonii with Antiviral Activity against Herpes Simplex Virus Type-2.

ABSTRACT: Two undescribed compounds, 3β,7β-dihydroxy-24-methylenelanosta-8-ene-11-one (1) and neolignane deightonin (4) were isolated from the aerial parts of Euphorbia deightonii Croizat together with six known compounds, namely, kansenone (2), euphorbol-7-one (3), dehydrodiconiferyl diacetate (5), marylaurencinol D (6), scoparon (7), and 3,4,3'-tri-O-methylellagic acid (8). The structures of the isolated compounds were determined by HRESIMS, 1D (1H, 13C JMOD) and 2D NMR (HSQC, HMBC, 1H-1H COSY, NOESY) spectroscopic analysis, and by comparison of the assignments with literature data. The anti-herpes simplex virus type-2 activity of the isolated compounds were investigated by qRT-PCR assay on Vero cells after determining cytotoxic concentration 50% (CC50). Compounds 1, 3, 4, and 7 exhibited inhibito
