Abstract

Provided herein are compounds of Formula (I), or pharmaceutically acceptable salts thereof, pharmaceutical compositions that include a compound described herein (including pharmaceutically acceptable salts of a compound described herein) and methods of synthesizing the same. Also provided herein are methods of treating diseases and/or conditions with a compound of Formula (I), or a pharmaceutically acceptable salt thereof.

Claims (40)

1. A compound of Formula (I), or a pharmaceutically acceptable salt thereof, having the structure:

wherein:

R 1 is an unsubstituted or a substituted C 2 alkenyl, an unsubstituted or a substituted C 2 alkynyl, wherein when the C 2 alkenyl and the C 2 alkynyl are substituted, the C 2 alkenyl and the C 2 alkynyl are independently substituted with one or more substituents selected from the group consisting of halogen, an unsubstituted C 1-4 alkyl, an unsubstituted C 1-4 haloalkyl, an unsubstituted C 1-4 hydroxyalkyl, an unsubstituted monocyclic C 3-6 cycloalkyl and a hydroxy-substituted monocyclic C 3-6 cycloalkyl;

R 2 and R 3 are taken together along with the carbon to which R 2 and R 3 are attached to form an unsubstituted or a substituted monocyclic C 3-6 cycloalkyl or an unsubstituted or a substituted monocyclic 3-6 membered heterocyclyl, wherein when the C 3-6 cycloalkyl and 3-6 membered heterocyclyl are substituted, the C 3-6 cycloalkyl and the 3-6 membered heterocyclyl are independently substituted with 1 or 2 substituents selected from the group consisting of halogen and hydroxy;

R 4 and R 5 are independently hydrogen, halogen, an unsubstituted C 1-4 alkyl, a deuterated C 1-4 alkyl or an unsubstituted C 2-4 alkenyl;

R 6 is hydrogen, an unsubstituted C 1-4 alkyl, a deuterated C 1-4 alkyl or an unsubstituted C 3-4 alkenyl; and

provided that at least one of R 4 , R 5 and R 6 is not hydrogen; or

R 5 is hydrogen, halogen, an unsubstituted C 1-4 alkyl or an unsubstituted C 2-4 alkenyl; and

R 4 and R 6 are taken together to form an unsubstituted or substituted 5-6 membered heterocyclic ring;

X 1 is CR A ;

R 7a , R 7c and R 7d are each hydrogen;

R 7b is cyano or an unsubstituted C 1-4 haloalkyl;

R 8 is hydrogen; and

R A is F.

2. The compound of claim 1 , wherein R 2 and R 3 are taken together along with the carbon to which R 2 and R 3 are attached to form an unsubstituted or a substituted monocyclic 3-6 membered heterocyclyl, wherein when the 3-6 membered heterocyclyl is substituted, the 3-6 membered heterocyclyl is substituted with 1 or 2 substituents selected from the group consisting of halogen and hydroxy.

3. The compound of claim 2 , wherein the monocyclic 3-6 membered heterocyclyl is selected from the group consisting of an unsubstituted or substituted oxetane, an unsubstituted or substituted thietane, an unsubstituted or substituted

an unsubstituted or substituted

an unsubstituted or substituted

an unsubstituted or substituted

an unsubstituted or substituted

and an unsubstituted or substituted

4. The compound of claim 1 , wherein R 4 is an unsubstituted C 1-4 alkyl; R 5 is an unsubstituted C 1-4 alkyl; and R 6 is an unsubstituted C 1-4 alkyl.

5. The compound of claim 4 , wherein R 4 , R 5 and R 6 are each methyl.

6. The compound of claim 1 , wherein R 7b is an unsubstituted C 1-4 haloalkyl.

7. The compound of claim 1 , wherein R 7b is cyano.

8. The compound of claim 6 , wherein R 7b is —CF 3 .

9. The compound of claim 1 , wherein R 1 is an unsubstituted C 2 alkenyl.

10. The compound of claim 1 , wherein R 1 is an unsubstituted C 2 alkynyl.

11. A compound selected from the group consisting of:

or a pharmaceutically acceptable salt of any of the foregoing.

12. A compound selected from the group consisting of:

or a pharmaceutically acceptable salt of any of the foregoing.

13. A compound selected from the group consisting of:

or a pharmaceutically acceptable salt of any of the foregoing.

14. A pharmaceutical composition comprising an effective amount of a compound of claim 1 , or a pharmaceutically acceptable salt thereof, and excipient.

15. A method for treating hepatitis B in a subject comprising administering to the subject in need thereof an effective amount of a compound of claim 1 , or a pharmaceutically acceptable salt thereof, suffering from hepatitis B.

16. A method for treating hepatitis D in a subject comprising administering to the subject in need thereof an effective amount of a compound of claim 1 , or a pharmaceutically acceptable salt thereof, suffering from hepatitis D.

17. The method of claim 15 , further comprising administering an additional agent selected from the group consisting of an interferon, a nucleoside analog, a nucleotide analog, a sequence specific oligonucleotide, a nucleic acid polymer, an entry inhibitor and a small molecule immunomodulator.

18. The method of claim 17 , wherein the additional agent selected from the group consisting of recombinant interferon alpha 2b, IFN-α, PEG-IFN-α-2a, lamivudine, telbivudine, adefovir dipivoxil, clevudine, entecavir, tenofovir alafenamide and tenofovir disoproxil.

19. The compound of claim 3 , wherein the monocyclic 3-6 membered heterocyclyl is an unsubstituted or substituted oxetane.
