It is an extracted and isolated alkaloid that has a strong nucleic acid synthesis inhibitory effect, and its action is rapid and reversible.It has a unique mechanism of action in that it does not show cross-resistance with existing anticancer drugs. Anti-tumor substance, murine leukemia L 1210 , rat walker
Although it has been recognized to have a strong anticancer effect on experimentally transplanted cancers such as 256 sarcoma, its usefulness as a drug is currently limited due to its toxic effects.

とは容易でないのが実情である。 However, camptothecin itself is poorly soluble in various organic solvents, and camptothecin has resistance to electrophilic substitution reactions due to the heterocycle in its structure. However, there are various obstacles, and the reality is that it is not as easy to obtain new derivatives as planned on paper.

ることができる。 The novel camptothecin-7-aldehyde derivative according to the present invention can be obtained in high yield by reacting camptothecin-7-aldehyde with various carbonyl reagents. Examples of such carbonyl reagents include hydroxylamine, hydrazine, methylhydrazine, phenylhydrazine, p-nitrophenylhydrazine, 2,4-dinitro-phenylhydrazine, p-toluenesulfonylhydrazine, N-aminoguanidine, 1- Amino-4-methylpiperazine, Girard's reagents: N.N-dimethylglycine hydrazide hydrochloride, trimethylammonium acetohydrazide chloride, pyridinium-acetohydrazide chloride and N-aminohydantoin, isonicotinic acid hydrazide, semicarbazide, phenyl-semicarbazide, Examples include thiosemicarbazide and semioxazoline. The reaction between camptothecin-7-aldehyde and these carbonyl reagents is a reaction between a conventional aldehyde and a carbonyl reagent. This reaction is preferably carried out in a suitable solvent such as ethanol, pyridine, acetic acid, etc. at room temperature to 80°C. When the carbonyl reagent to be used is a hydrochloride or sulfate, the reaction is carried out in pyridine or in the free form using a corresponding amount of sodium acetate, triethylamine, pyridine, etc. In the reaction of camptothecin-7-aldehyde with hydroxylamine, E-type oxime and Z
- type oxime is obtained in a ratio of approximately 1:1. 1
-Hydrazones obtained by reaction with amino-4-methylpiperazine or Girard's reagent are dissolved in water as a quaternary salt or a quaternized product such as a hydrochloride or a chloride at the N atom in R 1 or R 2 in the formula. can be done.
