Benefits of technology

[0070] The present invention relates to a pharmaceutical composition with improved solubility and stability comprising derivatives of GLP-1(1-45) and analogs and / or fragments thereof. The GLP-1 derivatives of the present invention have interesting pharmacological properites, in particular they have a more protracted profile of action than the parent peptides. The GLP-1 derivatives of the present invention also have insulinotropic activity, ability to decrease glucagon, ability to suppress gastric motility, ability to restore glucose competency to beta-cells, and / or ability to suppress appetite / reduce weight.

Problems solved by technology

A high clearance of a therapeutic agent is inconvenient in cases where it is desired to maintain a high blood level thereof over a prolonged period of time since repeated administrations will then be necessary.
In some cases it is possible to influence the release profile of peptides by applying suitable pharmaceutical compositions, but this approach has various shortcomings and is not generally applicable.
Furthermore, as an insulinotropic hormone, GIP was found to be almost ineffective in NIDDM (2).
Unfortunately, the high clearance limits the usefulness of these compounds.

example 1

Synthesis of Lys26(N?-tetradecanoyl)-GLP-1(7-37)

[1306] The title compound was synthesised from GLP-1(7-37). A mixture of GLP-1(7-37) (25 mg, 7.45 μm), EDPA (26.7 mg, 208 μm), NMP (520 ?l) and water (260 ?l) was gently shaken for 5 min. at room temperature. To the resulting mixture was added a solution of Myr-ONSu (2.5 mg, 7.67 μm) in NMP (62.5 ?l), the reaction mixture was gently shaken for 5 min. at room temperature and then allowed to stand for 20 min. An additional amount of Myr-ONSu (2.5 mg, 7.67 μm) in NMP (62.5 ?l) was added and the resulting mixture gently shaken for 5 min. After a total reaction time of 40 min. the reaction was quenched by the addition of a solution of glycine (12.5 mg, 166 μmol) in 50% aqueous ethanol (12.5 ml). The title compound was isolated from the reaction mixture by HPLC using a cyanopropyl column (Zorbax 300SB-CN) and a standard acetonitrile / TFA system, yield: 1.3 mg (corresponding to 4.9% of the theoretical yield). The column was heated to 65?C and...

Synthesis of Lys34(N?-tetradecanoyl)-GLP-1(7-37)

[1308] The title compound was isolated by HPLC from the reaction mixture described in Example 1. PDMS analysis yielded a protonated molecular ion at m / z 3567.7±3. The molecular weight was found to be 3566.7±3 amu (theoretical value: 3565.9 amu). The acylation site was determined on the basis of the fragmentation pattern.

Synthesis of Lys26,34-bis(N?-tetradecanoyl)-GLP-1(7-37)

[1309] The title compound was isolated by HPLC from the reaction mixture described in Example 1. PDMS analysis yielded a protonated molecular ion at m / z 3778.4±3. The molecular weight was found to be 3777.4±3 amu (theoretical value: 3776.1 amu).
