Definitions
- the invention relates to new tetrapeptides, their preparation and use.
- Dolastatin 15 is a substance described in US Pat. No. 4,879,278, which has the following formula.
- Dolastatin 15 is of great interest because of its high effectiveness against various tumors. Isolating it from the difficult-to-reach sea hare is lengthy and time-consuming, and the process delivers the active ingredient in moderate yield and with poorly reproducible quality. In order to make the active ingredient available in gram quantities for animal experiments, Pettit et al. (J. Am. Chem. Soc. Hl [1991] 6692-6693) developed a synthesis method. The central intermediate product is the tetrapeptide of the formula Ia -
- Me 2 Val — OPfp is synthesized according to Pettit et al. (US-PS 49 78 744) as follows:
- Valine is first methylated twice on nitrogen.
- the dimethylvaline thus obtained must be reacted with a condensing agent and pentafluorophenol (HO-Pfp).
- pentafluorophenol / carbodiimide e.g. Pentafluoro-20 phenyl-l, 2,2,2-tetrachloroethyl carbonate (J. Org. Chem. 5___ [1987] 2364) has no advantages.
- the invention now relates to a process for the preparation of the tetrapeptides I, which manages with intermediate products which are available in large quantities, which can be carried out without racemization and without endangering the environment.
- the invention relates to a process for the preparation of compounds of the formula
- R 1 , R 2 , R 3 and R 4 are the same or different and represent C 6 alkyl groups, characterized in that a compound of formula II
- R 1 has the meaning given above and Z represents a benzyloxycarbonyl protective group, which may be substituted on the phenyl ring, condenses and the compound obtained is methylated twice on the NH 2 group.
- R 1 , R 2 and R 3 which are the same or different, are preferably ethyl, n-propyl, isopropyl, t-butyl, sec-butyl, 2-methyl-n-but- l-yl or 3-methyl-n-but-l-yl groups.
- R 4 is preferably a methyl or ethyl group.
- the amino groups in the tetrapeptide preferably have the L configuration.
- the coupling reaction of II with III can be carried out, for example, according to the “mixed anhydride” method (see Houben-Weyl, Vol. XV / 2, 1974; J. Am. Chem. Soc. 74. [1952] 676; Coll. Czechoslov. Chem. Comm. 22 [1962] 1273).
- the carboxylic acid chlorides used as coupling reagents preferably pivalic acid chloride, 2-ethylbutyric acid chloride, isovaleric acid chloride
- chloroformic acid esters the methyl, ethyl, isopropyl, isobutyl, phenyl, chloroethyl and trichloromethyl esters are preferably used
- inexpensive reagents available in technical quantities, which are also well suited for syntheses on an industrial scale.
- the fact that the couplings according to the invention take place without racemization is particularly advantageous.
- Suitable solvents are tetrahydrofuran, dioxane, acetonitrile, dimethyl sulfoxide, ethyl acetate, dimethylformamide, methylene chloride, toluene, N-methylpyrrolidone and their mixtures. Methylene chloride, toluene or their mixtures are preferred.
- the reaction is carried out at temperatures between -40 ° C. and + 30 ° C., the temperature range -15 ° C. to + 15 ° C. is preferred.
- the invention further relates to the compounds of the formula I, in which, however, R 1 , R 2 and R 3 do not simultaneously represent isopropyl radicals when R 4 is a methyl group, and the salts thereof with different acids.
- acids which may be mentioned are: hydrochloric acid, citric acid, tartaric acid, lactic acid, phosphoric acid, methanesulfonic acid, acetic acid, formic acid, maleic acid, fumaric acid, malonic acid, succinic acid, malic acid, sulfuric acid, benzoic acid and oxalic acid.
- the compounds of the formula I are very suitable for the preparation of dolastatin 15 and numerous compounds which are described in WO 93/23424 (cf. Examples 214-246 and others) and which are notable for high antineoplastic activity .
- the compounds of formula I are also active against solid tumors (tumors of the lungs, breast, intestine, bladder, rectum, uterus, prostate), against leukemia, lymphomas and other neoplastic diseases.
- Me 2 Val means N, N-dimethyl-L-valine, MeVal N-methyl-valine, Me methyl, tert.
- Leu tertiary leucine HOOC-CH (NH 2 ) -C (CH 3 ) 3
- Me 2 tert. Leu N, N-dimethyl tertiary leucine and Me tert.
- the organic phase was extracted once with 40 1 2 N hydrochloric acid and twice with 40 1 2 N sodium hydroxide solution.
- the methylene chloride solvent was distilled off and replaced by 300 l of diisopropyl ether.
- the emulsion of the product oil was heated to 60 ° C. to crystallize the product, seed crystals were added and the mixture was kept at 60 ° C. for 7 hours.
- the mixture was stirred in succession for 5 h at 50 ° C. and 5 h at 40 ° C. and then cooled to 20 ° C.
- the crystal suspension was drained through a 120-1 pressure filter.
- reaction solution was separated from the catalyst and concentrated. The residue was taken up in ethyl acetate. The ethyl acetate solution is extracted twice with 2 N hydrochloric acid. The acidic aqueous phase was adjusted to pH 9 with sodium hydroxide solution and extracted twice with methylene chloride. The methylene chloride phase was then washed neutral and evaporated.
- the resulting suspension was heated to 60 ° C and then stirred for 12 h.
- the mixture was then cooled to 20 ° C. and stirred for a further 5 h.
- the mixture was then cooled to 5 ° C. and discharged through a 120-1 pressure filter.
- the filter cake was washed with 60 l of fresh, 5 ° C cold, methyl ethyl ketone. After pre-drying on the filter, the product was dried in vacuo at 40 ° C. to constant weight.
