PRI me R 1. 6 Methyl-8 - (3,5-dioxopiperazin-1-ylmethyl) -ergoline (1:. СНз;,).
A solution of 4.1 g of 6-methyl-8-tosyloxime-ergoline, 2,2-piperazine-3,5-dione and O, 2 g of potassium iodide in 80 ml of dimethylformamide is heated to a temperature that is maintained for 5 hours. . Dimethylformamide is reduced, the residue, dissolved in dichloromethylene, is washed with water and brine and dried over anhydrous sodium sulfate. After the radium has been filtered and the solvent has been removed, the products are crystallized from methanol to give 2.8 g of the title compound, m.p. 260-262 ° C.
Example 2. 1,6-Dimethyl-8D- (3,5-dioxopiperazin-1-ylmethyl) -ergo lin (1:,).
The process is carried out as in example 1 but. using 1,6-dimethyl-8 - tosyloxymethyl-zrgoline instead of 6-methyl-8-tosyloxymethyl-ergoline, c. the result is a target compound with a yield of 80%, so pl. 268-.

The procedures of Example 1 are performed, but 4-phenylpiperazine-3,5-dione is used instead of piperazine-3,5-dione, resulting in a compound from the title of the example in 70% yield, mp. 260-262 C.
Ergoline derivatives obtained according to the invention have moderate or good anti-hypertensive activity and can be used as agents that relieve anxiety or psychological stress.
Profiles of central sedative pharmacological activity were obtained by observing the behavior of Irwin mice, which also indicate acutely oriented toxicity 7 days after the start of observation, and by studying antagonism regarding central stereotypes caused by apomorphine (anxiety state) in mice.
The results obtained using the proposed compounds are given in table. 1 and 2.
To analyze antagonism regarding the state of anxiety caused by the use of apomorphine (Protais, P, et al. Psydiopharmacol ogy, 50, cf. I, 1976), these compounds were administered orally to male mice at a dose varying from 0.25 to 10 mg / kg 60 minutes before subcutaneous administration of 1 mg / kg apomorphine HC1. Antagonism regarding the state of anxiety caused by the administration of apomorphine was evaluated 10 minutes after administration of apomorphine.
It was also found that the proposed compounds do not induce relaxation of the lung system (Irwin's test for mice) and impaired coordination of motor functions (Rotarod test for rats, described by Dunham N. U. et al. J. Am. Pharm. Ass 46, . 208, 1957) with the oral administration of 10 mg / kg.
Action against hypertension.
Indirect measurements of systolic blood pressure were made in groups consisting of 4 rats with spontaneously increasing pressure (SHP, Kyoto) at the age of 8-10 weeks.
The animals were kept at 36 ° C for 10-15 minutes for registration.

pulse pressure, after which they measured systolic blood pressure by an indirect method using a blood measuring cuff — Hoi o pressure fixed to the tail, and a device for recording blood pressure W + W, model 8005. The test compounds were injected through the mouth suspended in 5% gum arabic, once a day for 4 days, and measurements were made before the start of treatment and 1-5 hours after the dose was administered on the first and fourth day of treatment.
Control animals received carrier only (0.2 ml / 100 g body weight). As a reference, 6-methyl-8 - (4-phenylpiperazino) - acetylzrgoline was tested.
Changes in systolic blood pressure caused by drugs were calculated as the difference between the values obtained and the values that occurred before treatment.
