Definitions
- the present invention relates to a cyclic hexane peptide compound or a salt thereof having an excellent antitumor effect.
- RA-V11 was not potent.
- An object of the present invention is to provide a cyclic hexapeptide compound having a better efficacy than RA-VII.
- the invention relates to the formula
- R ′ and R 2 each represent an alkyl group, a phenyl group or a benzyl group.
- n an integer of 4 to 6.
- the alkyl group is a linear or branched one having 1 to 4 carbon atoms, such as a methyl group, an ethyl group, an isopropyl group, an n-butyl group, a t-butyl group and the like. It is.
- the compound of the present invention can be produced as follows.
- a hydroxyl group of a compound in which R is a hydrogen atom (hereinafter referred to as RA-V) is represented by the formula R′-X (where R ′ represents R other than a hydrogen atom, and X is The compound can be produced by reacting with a halide containing a nitrogen atom represented by:
- N, N-dimethylformamide gives good results, but dimethylsulfoxide, 1,4-dioxane, acetone, methylethylketone, tetrahydrofuran, 1,2-dimethyloxetane, Methanol, ethanol and the like can also be used.
- This reaction is preferably performed in the presence of a base, and can be performed using, for example, lime carbonate, sodium carbonate, potassium hydride, or sodium hydride.
- a base for example, lime carbonate, sodium carbonate, potassium hydride, or sodium hydride.
- the reaction temperature depends on the boiling point of the solvent, it can usually be carried out at 5 to 80 ° C.
- Table 1 shows the structures and abbreviations of the compounds produced in the examples.
- RA—V 379 mg (0.5 Ommo 1) and 2-chloroethyldiisopropylamine hydrochloride 150 mg (0.75 mmo 1) are dissolved in 3 ml of N, N-dimethylformamide and carbonated.
- the reaction mixture was diluted with 2 mL of form 2 Om 1, dried over anhydrous sodium sulfate, filtered, and concentrated under reduced pressure.
- the residue obtained was applied to an alumina column chromatograph, and the form 50: 1) Purify the eluted part by silica gel column chromatography to obtain TI-356 32 1 mg from the form-methanol (20: 1) elution part.
- the compounds of the present invention can be prepared as injections using conventional formulation techniques and administered intravenously.
- the dose is 0.1 to 10 mg / m 2 per day, and this dose can be appropriately adjusted according to the patient's age, weight, symptoms, and the like.
- This cell suspension was subcutaneously transplanted as a 0.2 m 1 Z mouse into the lower right of the CDF, male male mouse (6-week-old Nippon Chal River), and used as a tumor-bearing mouse for testing.
- One group consisted of 8 animals. Assuming that the cell transplantation day is day 0, detergent (HC (HC (HC) (HC (HC) (HC (HC).
- RA-VII was used as a control.
- Tumor growth inhibitory effect is measured by measuring the major axis and minor axis of the tumor with a caliper on the day following the end of compound administration (day 8), and calculating the tumor volume, tumor volume ratio, and T / C (%) using the following formulas. Judged. It was determined to be valid when T / C was 42% or less. Table 3 shows the results.
- Cn tumor volume of the control group n days after the start of administration
- Tn Tumor volume of the drug administration group ⁇ days after the start of administration
