Assignee: Hoffmann-La Roche Inc. (Nutley, NJ)
Application Number:06/621,827
Patent Claims: 1. A compound of the formula ##STR12## wherein A is the group ##STR13## or --(CH.sub.2).sub.5 --.

2. The compound of claim 1, (2S,3S,5S,7Z,10Z)-5-[(S)-2-formamido-4-methyl-valeryloxy]-2-hexyl-3-hydrox y-7,10-hexadecadienoic 1,3 acid lactone.

3. The compound of claim 1, (2S,3S,5S)-5-[(S)-2-formamido-4-methyl-valeryloxy]-2-hexyl-3-hydroxy-hexad ecanoic 1,3 acid lactone.

4. A pharmaceutical composition for administration to a patient comprising

(a) about 5% to about 95% of a compound of formula ##STR14## wherein A is the group ##STR15## or --(CH.sub.2).sub.5 -- said composition being present in a amount sufficient to supply about 0.1 to about 100 mg of compound I per kilogram of body weight of the patient per day; and

(b) 5% to 95% of a pharmaceutically acceptable inert carrier material, said composition being formulated in a unit dosage form.

5. The composition of claim 4 wherein said composition is formulated in an oral unit dosage form.

6. The composition of claim 5 wherein said oral unit dosage form is a tablet, dragee, capsule, solution, emulsion or suspension.

7. The composition of claim 4 wherein compound I is (2S,3S,5S,7Z,10Z)-5-[(S)-2-formamido-4-methyl-valeryloxy]-2-hexyl-3-hydrox y-7,10-hexadecadienoic 1,3 acid lactone.

8. The composition of claim 4 wherein compound I is (2S,3S,5S)-5-[(S)-2-formamido-4-methyl-valeryloxy]-2-hexyl-3-hydroxy-hexad ecanoic 1,3 acid lactone.

9. A method of treating obesity in an afflicted mammal comprising administering to the mammal a compound of the formula ##STR16## wherein A is the group ##STR17## or --(CH.sub.2).sub.5 -- in an amount which is effective in treating obesity.

10. The method of claim 9 wherein compound I is (2S,3S,5S,7Z,10Z)-5-[(S)-2-formamido-4-methyl-valeryloxy]-2-hexyl-3-hydrox y-7,10-hexadecadienoic 1,3 acid lactone.

11. The method of claim 9 wherein compound I is (2S,3S,5S)-5-[(S)-2-formamido-4-methyl-valeryloxy]-2-hexyl-3-hydroxy-hexad ecanoic 1,3 acid lactone.

12. The method of claim 9 wherein compound I is administered in a daily dose of about 0.1 mg to 100 mg/kg body weight of the mammal.

13. A method of treating hyperlipaemia in an afflicted mammal comprising adminstering to the mammal a compound of the formula ##STR18## wherein A is the group ##STR19## or --(CH.sub.2).sub.5 --, in an amount which is effective in treating hyperlipaemia.

14. The method of claim 13 wherein compound I is (2S,3S,5S,7Z,10Z)-5-[(S)-2-formamido-4-methyl-valeryloxy]-2-hexyl-3-hydrox y-7,10-hexadecadienoic 1,3 acid lactone.

15. The method of claim 13 wherein compound I is (2S,3S,5S)-5-[(S)-2-formamido-4-methyl-valeryloxy]-2-hexyl-3-hydroxy-hexad ecanoic 1,3 acid lactone.

16. The method of claim 13 wherein compound I is administered in a daily dose of about 0.1 mg to 100 mg/kg body weight of the mammal.

17. A method of preventing obesity in a mammal comprising administering to the mammal a compound of the formula ##STR20## wherein A is the group ##STR21## or --(CH.sub.2).sub.5 --, in an amount which is effective in preventing obesity by inhibiting pancrease lipase.

18. The method of claim 17 wherein compound I is (2S,3S,5S,7Z,10Z)-5-[(S)-2-Formamido-4-methyl-valeryloxy]-2-hexyl-3-hydrox y-7,10-hexadecadienoic 1,3 acid lactone.

19. The method of claim 17 wherein compound I is (2S,3S,5S)-5-[(S)-2-formamido-4-methyl-valeryloxy]-2-hexyl-3-hydroxy-hexad ecanoic 1,3 acid lactone.

20. The method of claim 17 wherein compound I is administered in a daily dose of about 0.1 mg to 100 mg/kg body weight of the mammal.
