摘要:
Rhein analogues that exhibit anti-proliferative activity, particular against cancer cells, are described herein. In some embodiments, the compounds contain a flat or planar ring system. Such rings system by facilitate non-covalent binding of the compounds to the DNA complex, such as by intercalation. In some embodiment, the compounds contain a flat or planar ring system as described above and one or more substituents which are alkylating moieties, electrophilic groups or Michael acceptors or groups which contain one or more alkylating moieties, electrophilic groups and/or Michael acceptors. The compounds described herein can also contain one more functional groups to improve the solubility of the compounds.

摘要:
Novel glycolipid derivatives, where the substituent of the sphingosine base part is a short carbon chain alkyl group, substituted or unsubstituted cycloalkyl group, substituted or unsubstituted aryl group or substituted or unsubstituted aralkyl group and efficient synthetic methods for practical mass production of the same and intermediates useful for the synthesis of these compounds. Glycolipids having the formula (I):
where R 3 indicates a substituted or unsubstituted C 1 to C 7 linear alkyl group, substituted or unsubstituted cycloalkyl group, substituted or unsubstituted aryl group, or substituted or unsubstituted aralkyl group and R 8 indicates a substituted or unsubstituted C 1 to C 35 alkyl group, substituted or unsubstituted aryl group or substituted or unsubstituted aralkyl group are chemically synthesized.
