Precursors and derivatives of camptothecin, a process for their preparation, their use and pharmaceutical compositions containing them |
| abstract |
InterLn = 1333;> (57) The present invention relates to novel camptothecin derivatives wherein the hydroxylactone group of camptothecin is replaced by a b-hydroxy lactone group or a corresponding b-hydroxy acid resulting from the opening of a lactone. The novel compounds are characterized in that they contain an optionally substituted oxazine ring which fits at positions 10 and 11 of the A ring. The present invention also relates to the preparation of novel compounds and pharmaceutical compositions prepared therefrom. The compounds of the present invention have antitumor, antiviral and parasiticidal properties. SHE |
