Abstract

Acyclic CB[n]-type compounds, methods of making such compounds, and uses of the compounds. For example, these compounds can be used as nanocontainers to solubilize pharmaceutical agents. Also provided are compositions and methods of using them for therapy or prophylaxis of a wide variety of conditions for which therapy or prophylaxis is desirable.

Claims (35)

1. A composition comprising a compound having the following structure:

or a salt, a partial salt, a hydrate, or a stereoisomer thereof,

wherein each R is independently hydrogen, C 1 to C 20 alkyl group, C 3 to C 20 carbocyclic group, C 1 to C 20 heterocyclic group, carboxylic acid group, ester group, amide group, hydroxy, or ether group;

wherein, optionally, adjacent R groups form a C 3 to C 20 carbocyclic ring or heterocyclic ring;

wherein each

is independently a C 5 to C 20 carbocyclic ring system or C 2 to C 20 heterocyclic ring system, wherein the ring system comprises one or more rings;

wherein at least one ring system has at least one solubilizing group selected from sulfonic acid group, sulfonate salt group, phosphonic acid group, phosphonate salt group, and polyethylene glycol group;

wherein, optionally, the ring system has a targeting group;

wherein n is 1 to 5,

wherein the composition is in the form of a powder for reconstitution.

2. The composition of claim 1 ,

wherein each

in the compound is independently a C 5 to C 20 carbocyclic ring system having one of the following structures:

wherein at each occurrence of

R 1 to R 16 is independently hydrogen, C 1 to C 20 alkyl group, halo group, hydroxyl group, nitro group, carboxylic acid group, ester group, amide group, ether group, C 3 to C 20 carbocyclic group, or C 1 to C 20 heterocyclic group, provided that at least one of R 1 to R 16 in the compound has the following structure:

wherein LG is a linking group and X is the solubilizing group; and

wherein optionally one or more adjacent R 1 to R 16 groups are connected forming a carbocyclic ring or heterocyclic ring.

3. The composition of claim 2 , wherein in the compound

has the following structure:

wherein each I is 1 to 20.

4. The composition of claim 2 , wherein in the compound at least one of the R 1 to R 16 groups in the structure has the following structure:

and wherein LG is a linking group and wherein TG is the targeting group.

5. The composition of claim 2 , wherein in the compound the

groups are the same.

6. The composition of claim 3 , wherein the compound in the composition has one of the following structures:

wherein Z is a poly(ethylene glycol) (PEG) group having a molecular weight of 200 to 10,000.

7. The composition of claim 3 , wherein the compound in the composition has one of the following structures:

wherein A + is H + , Na + , K + , Ca 2+ , Mg 2+ , Zn 2+ , H 4 N + , Et 3 NH + , Me 4 N + , (HOCH 2 CH 2 ) 3 NH + , or a cationic form of ethylenediamine, piperazine, and trishydroxymethyl aminomethane (TRIS).

8. The composition of claim 3 , wherein the compound has the following structure:

wherein A + is H + , Na + , K + , Ca 2+ , Mg 2+ , Zn 2+ , H 4 N + , Et 3 NH + , Me 4 N + , (HOCH 2 CH 2 ) 3 NH + , or a cationic form of ethylenediamine, piperazine, and trishydroxymethyl aminomethane (TRIS).

9. The composition of claim 8 , wherein A + is Na + .

10. The composition of claim 3 , wherein the compound has the following structure:

wherein A + is H + , Na + , K + , Ca 2+ , Mg 2+ , Zn 2+ , H 4 N + , Et 3 NH + , Me 4 N + , (HOCH 2 CH 2 ) 3 NH + , or a cationic form of ethylenediamine, piperazine, and trishydroxymethyl aminomethane (TRIS).

11. The composition of claim 10 , wherein A + is Na + .

12. The composition of claim 7 , wherein A + is Na + .
