Abstract

The invention relates to novel polyethylene glycol (PEG) based prodrug of Adrenomedullin, to processes for preparation thereof, to the use thereof for treatment and/or prevention of diseases, and to the use thereof for producing medicaments for treatment and/or prevention of diseases, especially of cardiovascular, edematous and/or inflammatory disorders.

First claim

The invention claimed is:

1. A compound of the formula

in which
n represents the number 0, 1, 2 or 3,
R 1 represents hydrogen, methyl, ethyl, n-propyl or isopropyl,
R 2 represents linear or branched PEG 20 kDa to 80 kDa endcapped with a methoxy-group, or a salt thereof.

2. The compound of claim 1 , wherein
n represents the number 1 or 2,
R 1 represents hydrogen or methyl,
R 2 represents linear PEG 40 kDa endcapped with a methoxy-group.

3. The compound of claim 1 , wherein
n represents the number 1 or 2,
R 1 represents hydrogen,
R 2 represents linear PEG 40 kDa endcapped with a methoxy-group.

4. A process for preparing a compound of the formula (I) or a salt thereof, as claimed in claim 1 , comprising reacting a compound of formula (II)

in which
n and R 1 are each as defined in claim 1 ,
with a compound of the formula (III)

in which
R 2 is as defined in claim 1 .

5. A method of treatment of a cardiovascular, edematous and/or inflammatory disorder comprising administering to a human or animal an active amount of a compound of claim 1 .

6. A pharmaceutical composition comprising a compound as claimed in claim 1 in combination with an inert nontoxic pharmaceutically suitable excipient.

7. The pharmaceutical composition of claim 6 , further comprising a further active ingredient.

8. A method of treatment of a cardiovascular, edematous and/or inflammatory disorder comprising administering to a human or animal an active amount of a pharmaceutical composition of claim 6 .

9. The method of claim 8 , wherein the cardiovascular, edematous and/or inflammatory disorder is selected from the group consisting of heart failure, coronary heart disease, ischemic and/or hemorrhagic stroke, hypertension, pulmonary hypertension, peripheral arterial occlusive disease, pre-eclampsia, chronic obstructive pulmonary disease, asthma, acute and/or chronic pulmonary edema, allergic alveolitis and/or pneumonitis due to inhaled organic dust and particles of fungal, actinomycetic or other origin, and/or acute chemical bronchitis, acute and/or chronic chemical pulmonary edema, neurogenic pulmonary edema, acute and/or chronic pulmonary manifestations due to radiation, acute and/or chronic interstitial lung disorders, acute lung injury/acute respiratory distress syndrome (ALI/ARDS) in adult or child including newborn, ALI/ARDS secondary to pneumonia and sepsis, aspiration pneumonia and ALI/ARDS secondary to aspiration, ALI/ARDS secondary to smoke gas inhalation, transfusion-related acute lung injury (TRALI), ALI/ARDS and/or acute pulmonary insufficiency following surgery, trauma and/or burns, and/or ventilator induced lung injury (VILI), lung injury following meconium aspiration, pulmonary fibrosis, mountain sickness, glomerulonephritis, acute kidney injury, cardiorenal syndrome, lymphedema, inflammatory bowel disease, sepsis, septic shock, systemic inflammatory response syndrome (SIRS) of non-infectious origin, inflammatory bowel disease and urticaria.
