Rearranged abietane diterpenoids from the root of teucrium polium subsp. vincentinum
1990
Abstract From the root of Teucrium polium subsp. vincentinum (Labiatae) four new rearranged abietane derivatives, teuvincenones A, B, C, and D (1-4, respectively), have been isolated. Two of these compounds, teuvincenones C (3) and D (4), possess a novel hydrocarbon skeleton which contains a cyclopropane ring constituted by the C-3, C-4, and C-18 carbons of the 17(15→16)-abeo-abietane framework. The structures of these diterpenoids were established mainly by spectroscopic means and, in the case of teuvincenones A (1) and C (3), also confirmed by X-ray diffraction analyses.

Grazoprevir/elbasvir for the immediate treatment of recently acquired HCV genotype 1 or 4 infection in MSM.
2020
Abstract Background In Europe, increases in HCV infection have been observed over the last two decades in MSM, making them a key population for recently acquired HCV. Alternative combinations of direct-acting antiviral agents against early HCV infection need to be assessed. Patients and methods In this pilot trial, MSM with recently acquired genotype 1 or 4 HCV infection were prospectively included and received 8 weeks of oral grazoprevir 100 mg and elbasvir 50 mg in a fixed-dose combination administered once daily. The primary endpoint was sustained virological response evaluated 12 weeks after the end of treatment (EOT) (SVR12). Secondary endpoints were the virological characterization of…
