    Description / Table of Contents: Zusammenfassung N2-substituierte 5-Methylisocytidin-Derivate wurden ausgehend von S2-Methyl-2-thiothymidin entweder durch direkte Substitution der Methylthiogruppe durch eine Aminogruppe und anschließende Kondensation mit 1,2,3,5-tetra-O-Acetyl-β-D-ribofuranose zum acetylierten Nucleosid oder umgekehrt durch Synthese eines acetylierten 5,S2-Dimethyl-2-thiouridins und nachfolgende Behandlung mit dem entsprechenden Amin hergestellt.
    Notes: Summary N2-Substituted 5-methylisocytidine derivatives were synthesized from S2-methyl-2-thiothymine either by direct substitution of the methylthio group by an amino group and subsequent condensation with 1,2,3,5-tetra-O-acetyl-β-D-ribofuranose to give the acetylated nucleoside or by the opposite sequence first preparing an acetylated 5,S2-dimethyl-2-thiouridine followed by treatment with the appropriate amine.

    Notes: Abstract This study examined the effects of lisinopril on diastolic function in 12 normotensive patients (mean age 72 years) with symptomatic congestive heart failure, intact left ventricular systolic function and abnormal diastolic function secondary to ischaemic heart disease in a placebo-controlled double blind crossover study, with each treatment dosed orally for 5 continuous weeks. Compared to placebo, lisinopril significantly decreased blood pressure, increased plasma renin activity without altering heart rate or plasma norepinephrine. There was no statistically significant improvement with lisinopril in radionuclide derived peak filling rate and time to peak filling rate, in Doppler echocardiographic measurements of the ratio of peak flow velocity in early diastole to the peak flow velocity of atrial contraction (E:A ratio) and in visual analogue scales of symptoms. Thus, although angiotension converting enzyme inhibitors may have an established role in the treatment of heart failure secondary to left ventricular systolic dysfunction, its use in patients with isolated diastolic dysfunction remains unclear.
