The present invention is based on the general formula (): (In the formula, Mep represents a 2-mercaptopropionyl residue (-S-CH 2 CH 2 CO-), and D-arginine is present at the 8th position.) Antidiuretic activity with no side effects and long-lasting action. The present invention relates to a method for producing desamino-asparagine 4 -D-arginine 8 -vasopressin. The duration of antidiuretic activity of vasopressin is influenced by the rate of enzymatic degradation of the intact peptide. Structural changes in peptides that reduce the rate of enzymatic decay while retaining biological activity are highly desirable, especially when improving and prolonging the resulting therapeutic action. Replacement of cysteine moiety at position 1 by Mep and L at position 8 by D-arg in arginine-vasopressin
−arg substitution is similar to vasopressin
It reduces desamino-D-arginine 8 -vasopressin, known as DDAVP, and has a long-lasting antidiuretic effect, as well as a significant relief effect on non-striated muscles in the vascular system. , superior to vasopressin. Both of these actions are effective in treating diabetes insipidus. In addition to the effects mentioned above, when a pregnant woman suffers from diabetes insipidus, it is necessary to consider the effect of uterine contraction. Older vasopressin derivatives in therapeutic use have too high a uterine tonic effect to be given to pregnant women without the risk of miscarriage. For this reason, it is highly desirable to have a medicament with a sufficiently low uterine tonic effect for therapeutic administration to pregnancies suffering from diabetes insipidus. In view of constant diabetes insipidus, ie long-term treatment, the patient runs the risk of becoming immune to the drug or becoming hyperesthetized after the treatment period. In order to allow continuous treatment of the disease, it is necessary in this case to use certain other corresponding drugs that do not cause the above-mentioned immune or allergic reactions in the patient. However, to date, such other classes of drugs against vasopressin and DDAVP have not been used. The aim of the invention is therefore to eliminate such drawbacks. The object of the present invention is to provide a new vasopressin derivative that has an antidiuretic effect comparable to that of conventional preparations, and a significantly lower uterine tonic effect, with significantly improved antidiuretic/uterotonic effects. In particular, the uterine tonic effect of the preparation of the present invention is 10 tenth potency lower and 10 tenth potency higher than that of conventional preparations.
It has unique properties that produce a uterine tonic effect ratio. For this reason, the compounds of the present invention can be used to treat pregnant women suffering from diabetes insipidus, and can be used to treat such women throughout pregnancy; This is a completely new field of treatment for women. The present invention is based on the following general formula: (In the formula, Mep represents 2-mercaptopropionyl.)
acid sequence) is gradually formed in a manner known per se, and then this amino acid sequence is oxidized to the general formula: Desamino-asparagine 4 -D-
It is characterized by producing arginine 8 -vasopressin. According to another aspect of the invention, the oxidation is carried out with potassium ferricyanide in aqueous solution at a pH of 6.5 to 7.0. The polypeptide according to the invention can be used in free base form as a salt of an inorganic or organic acid,
Auxiliaries, stabilizers and preservative additives
additives), sweeteners, aromatics, humectants, etc. can be added, and parenteral, oral, intranasal,
It can be formulated for subcutaneous, intramuscular and intravenous administration. Examples of inorganic acids that can be used include hydrochloric acid and phosphoric acid, and examples of organic acids that can be used include acetic acid, citric acid, and tartaric acid. Additionally, compounds having acid action such as tannins can be used. Suitable additives include starch, lactose, natural or cured oil, talc, glycerin, and the like. An advantage of the new compounds is good intranasal resorbability.
This is easy to administer to the patient, and the preparation can be administered intranasally. This eliminates the need for injections by intravenous administration, which is complicated in some situations. The peptide in the present invention has the following formula: is a protecting group for the mercapto group (benzyl) of cysteine and Y is a protecting group for the guanidine nitrogen (p-toluenesulfonyl).
off point). The protecting group X was removed and the pentapeptide was converted into the pentapeptide with the following formula (): (Y)-Gly-indicates p-nitrophenyl ester group for NH2 )
It binds to the peptide represented by Removing the protecting group X of the peptide () and converting the hexapeptide to the tripeptide hydrazine (): Mep(Bzl)-Tyr-Phe- NHNH2 protected nonapeptide amide (): Mep(Bzl)-Tyr-Phe-Asn- Coupling is performed by the azide coupling method to obtain Asn-Cys(Bzl)-Pro-D-Arg(Y)-Gly- NH2 . Treatment of the protected nonapeptide amide with an alkali metal in liquid ammonia splits the protecting group and reduces the nonapeptide amide (): Mep(SH)−Tyr−Phe−Asn−Asn−Cys(SH)−Pro−D− Arg-Gly- NH2 is generated and this product is oxidized at a pH of 6.5-7.0 in an aqueous potassium ferricyanide solution to form the general formula ()
A cyclic biologically active peptide is obtained. Substitution of the amino acid of vasopressin at position 4 by asparagine in concert with the substitution of the cysteine moiety at position 1 by Mep and the L-arginine at position 8 by D-arginine is
In addition to good intranasal resolvability compared to vasopressin, it produces a peptide () that has a high antidiuretic effect, an effect of reducing the increase in blood pressure and a significantly reduced uterine tonic effect (see Table 1).
DDAVP is listed in Table 1 separately from arginine-vasopressin as a standard substance, and it is also listed in the literature (Chemical Abstracts: 80 , 347V (1974)).
The analogous 4-Val-DDAVP described in Table 1 is also listed in the table. Since the theoretical dose curve for the response of antidiuretic peptides with general formula () is not linear, the number of units/mg for D-arginine 8 -analogues compared to vasopressin is not linear.
Therefore, it is difficult to express the activity normally. For this reason, the intensities in the table are expressed as relative activity values and data of DDAVP when the comparison compound is arbitrarily set at 1.00.
