    摘要: The invention provides a method of inhibiting cancer cell growth, and thereby of treating cancer comprising administering to a mammal afflicted with cancer an effective amount of the compound of formula (I), wherein the variables of R.sub.1, and R.sub.2 have the meanings defined in the specification. The present invention also provides novel compounds of formula (I) as well as novel pharmaceutical compositions and intermediates useful for preparing compounds of formula (I). The figure illustrates the structure and binding activity of compounds of the invention and some of the rifamycin analogs.______________________________________ ##STR1## ______________________________________ Compounds R.sub.1 = ______________________________________ A1 --OH A2 --OH A3 --OH A4 --OH A5 --OH A6 --OH A7 --OH - A8 ##STR2## ______________________________________ Compounds R.sub.2 = ______________________________________ A1 #STR3## - A2 #STR4## - A3 #STR5## - A4 #STR6## - A5 #STR7## - A6 #STR8## - A7 #STR9## - A8 --H ______________________________________ Compounds IC.sub.50 (1) IC.sub.50 (2) ______________________________________ A1 10 uM 1 uM A2 10 uM 3 uM A3 10 uM 3 uM A4 50 uM 5 uM A5 >500 uM >50 uM A6 >500 uM >50 uM A7 >200 uM >50 uM A8 >500 M >50 uM ______________________________________

    摘要: A process is disclosed for the production of polyphenol oligomers having n polyphenol monomeric units, n being an integer from 2-18. The process includes coupling of a protected polyphenol, having protected phenolic hydroxyl groups, with a C-4 functionalized polyphenol monomer. The protected polyphenol may be a protected polyphenol monomer or a protected polyphenol oligomer having 2-17 monomeric units. Advantageously, polyphenol monomeric units forming the polyphenol oligomers may be the same or different flavanoid compounds.
