The present invention is based on the following general formula () (In the formula, n represents an integer of 1 to 3, R 1 and
R 2 represents a lower alkyl group),
This invention relates to N-dialkylcarbamate esters. Conventionally, regarding carbamate esters of terpene alcohols, diphenylcarbamate ester of geraniol is known as a derivative for separation of geometric isomers, and some carbamate esters of terpene alcohols have anti-inflammatory or antispasmodic effects. It is known to have an effect. For example, Japanese Patent Publication No. 44-20086 describes carbamylic acid esters of bisabolol, geraniol, citronellol, borneol, and α-terpineol as compounds with anti-inflammatory effects, and the Journal of Medicinal Chemistry ,
1972, Vol. 15, No. 9, page 998, prenol,
The anticonvulsant action of unsubstituted carbamate esters of homoprenol, citronellol, geraniol, nerol and farnesol has been described. The present inventors have discovered that the novel N,N-dialkylcarbamate represented by the general formula () has an antitumor effect, and have completed the present invention. Represents a lower alkyl group in the general formula ()
R 1 and R 2 can be, for example, methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, sec-butyl, tert-butyl, and the like. N of the present invention represented by general formula (),
The following compounds are exemplified as N-dialkylcarbamate esters. However, in the following G
-, Fa- and G.G- are each a 3,7-dimethyloct-2,6-dien-1-yl group,
3,7,11-trimethyldodeca-2,6,10-trien-1-yl group and 3,7,11,15-tetramethylhexadec-2,6,10,14-tetraen-1-yl group means. The N,N-dialkylcarbamate represented by the general formula () can be produced by various methods known as methods for producing carbamates, except for using the corresponding starting materials. For example, the general formula () below (In the formula, n has the same meaning as in the general formula ()) and the following general formula () (In the formula, R 1 and R 2 have the same meanings as in the general formula (), and X represents a halogen atom)
By reacting the N,N-dialkylcarbamoyl halide represented by in the presence of a basic condensing agent such as pyridine or sodium hydride, an N,N-dialkylcarbamate ester represented by the general formula () can be obtained. . This reaction is typically performed using e.g. dioxane, tetrahydrofuran,
It is carried out in the presence of a suitable solvent such as an aromatic hydrocarbon, dimethyl sulfoxide, etc. at a temperature of about 0 to 150°C. The N,N-dialkylcarbamate ester represented by the general formula () provided by the present invention has an antitumor effect as described above, and is therefore useful as a pharmaceutical agent such as an antitumor agent. For example, in the general formula (), n=2 and R 1 =R 2 =CH 3 , ie, a compound of pharnesylethyl N,N-dimethylcarbamate, the pharmacological data are as follows. Antitumor effect: 2.5 x 106 Ehritzch ascites tumor cells were intraperitoneally transplanted into ddY- mice (male, 5 weeks old), and 24 days after transplantation.
After a period of time had elapsed, pharnesylethyl N,N-dimethylcarbamate was intraperitoneally administered according to the administration schedule shown in Table 1. The number of days each mouse survived was observed, and the survival rate was calculated based on the median value.

Example 1 25.0 g of 5,9,13-trimethyltetradeca-4,8,12-trien-1-ol (also known as farnesylethanol) was placed in a 300 ml three-necked flask equipped with a thermometer and a reflux condenser. and 100 ml of dry dioxane were added thereto, and 5.0 g of oily sodium hydride (sodium hydride content: approximately 50% by weight) was gradually added under ice cooling. Then, 12 g of N,N-dimethylcarbamoyl chloride [(CH 3 ) 2 NCOCl] was gradually added dropwise under ice cooling. After the dropwise addition was completed, the mixture was heated and reacted for 1 hour under dioxane reflux. After the reaction is complete,
The generated salt was separated and dioxane was distilled off from the liquid. The residue was subjected to liquid chromatography (using Waters System 500) using n-hexane containing 0.5% by weight of isopropanol as a developing solvent, and 23.2 g of a pale yellow liquid was separated. This substance was confirmed by proton NMR and mass spectrometry to be pharnesylethyl N,N-dimethylcarbamate shown by the following structural formula. NMR data is shown below. (90MHz, CDCl 3
