Claims (29)

1. A compound of formula (3):

wherein

R is hydrogen, —(C 1 -C 6 )alkyl, —(C 2 -C 4 )alkenyl, phenyl, benzyl, cyclopentyl, cyclohexyl, —(C 5 -C 7 )heterocycloalkyl, benzyloxy, —O—(C 1 -C 6 )alkyl, —NH 2 , —NH—(C 1 -C 4 )alkyl, or —N((C 1 -C 4 )alkyl) 2 ,

wherein said —(C 1 -C 6 )alkyl, —(C 2 -C 4 )alkenyl, phenyl, benzyl, cyclopentyl, cyclohexyl, —(C 5 -C 7 )heterocycloalkyl, benzyloxy, —O—(C 1 -C 6 )alkyl, —NH—(C 1 -C 4 )alkyl, or —N((C 1 -C 4 )alkyl) 2 can be unsubstituted or substituted with one or more substituents selected from halo, —(C 1 -C 6 )alkyl, —(C 2 -C 4 )alkenyl, —(C 2 -C 3 )alkynyl, -(5- or 6-membered)heteroaryl, —O—(C 1 -C 6 )alkyl, —S—(C 1 -C 6 )alkyl, —C(halo) 3 , —CH(halo) 2 , —CH 2 (halo), —CN, —NO 2 , —NH 2 , —NH—(C 1 -C 4 )alkyl, —N(—(C 1 -C 4 )alkyl) 2 , —C(═O)(C 1 -C 4 )alkyl, —C(═O)O(C 1 -C 4 )alkyl, —OC(═O)(C 1 -C 4 )alkyl, —OC(═O)NH 2 , —S(═O)(C 1 -C 4 )alkyl, or —S(═O) 2 (C 1 -C 4 )alkyl.

2. The compound of claim 1 , wherein R is methyl or ethyl.

3. The compound of claim 1 , wherein R is methyl.

4. The compound of claim 1 , wherein R is ethyl.

5. The compound of claim 1 , wherein R is benzyl or phenyl.

6. The compound of claim 1 , wherein R is phenyl.

18. The pharmaceutical composition of claim 17 , wherein the pharmaceutical composition is suitable for intravenous administration.

19. The pharmaceutical composition of claim 17 , wherein the at least one pharmaceutically acceptable excipient is at least one species of cyclodextrin.

20. The pharmaceutical composition of claim 19 , wherein the pharmaceutical composition is suitable for intravenous administration.

21. A method of treating a cardiovascular disease, comprising administering an effective amount of the pharmaceutical composition of claim 17 a patient in need thereof.

22. The method of claim 21 , wherein the pharmaceutical composition is administered intravenously.

23. The method of claim 21 , wherein the cardiovascular disease is heart failure.

24. The method of claim 23 , wherein the pharmaceutical composition is administered intravenously.
