    摘要: Polycyclic alkaloids of formula (I), wherein R.sub.1 is H, C.sub.1-6 alkyl, or C.sub.6-12 aryl optionally substituted with polar groups; R.sub.2 and R.sub.3 are independently H, OH, C.sub.1-6 alkyl, --C(NH)--NH.sub.2, a positively charged group, or C.sub.7-13 aralkyl optionally substituted with NH.sub.2, OH, C.sub.1-6 alkyl, or halogen; or R.sub.2 and R.sub.3 together form a 5 to 6 member ring optionally incorporating a heteroatom; R.sub.4 is H, C.sub.1-6 alkyl, OR.sub.6, SR.sub.6, or N(R.sub.6).sub.2, wherein each R.sub.6 is independently H, C.sub.1-3 alkyl; X ix O, S, SO, SO.sub.2, or N--R.sub.5, wherein each R.sub.5 is independently H, C.sub.1-6 alkyl, or C.sub.7-13 aralkyl optionally interrupted with one or more heteroatom; n is an integer from 0 to 2; and m is an integer from 0 to 3. These compounds act as antagonists at the ionotropic NMDA (N-methyl-(D)-aspartic acid) receptor. ##STR1##

    摘要: Nucleoside analogues containing a 1,3-dioxolane structure are suitable antiviral agents, particulary for the treatment of the HIV infections in mammals, especially humans. Examples of the nucleoside analogues include: cis-2-acetoxymethyl-4-(thymin-1′-yl)-1,3,-dioxolane, cis-2-hydroxymethyl-4-(thymin-1′-yl)-1,3-dioxolane, cis-2-benzoyloxymethyl-4-(cytosin-1′-yl)-1,3-dioxolane, and cis-2-hydroxymethyl-4-(cytosin-1′-yl)-1,3-dioxolane. These compounds can be in the form of their racemates or their separate enantiomers.
