Abstract

The present disclosure provides, inter alia, compounds with MASP-2 inhibitory activity, compositions of such compounds, and methods of making and using such compounds.

Claims (37)

1. A compound having the following Structure (I):

or a stereoisomer, tautomer, or pharmaceutically acceptable salt thereof, wherein:

R 1 is a substituted or unsubstituted aryl, substituted or unsubstituted cycloalkyl, a substituted or unsubstituted heterocyclyl, or a substituted or unsubstituted heteroaryl, wherein the heteroaryl is selected from the group consisting of

R 2 is hydrogen, alkyl, alkoxy, haloalkyl, haloalkoxy, or cycloalkyl;

R 3 is hydrogen, alkyl, haloalkyl, or cycloalkyl;

or R 2 and R 3 , together with the carbon and nitrogen to which they are attached, respectively, form an optionally substituted 4-7 membered heterocyclyl;

R 4 is a substituted or unsubstituted aryl, substituted or unsubstituted heteroaryl, substituted or unsubstituted cycloalkyl, or a substituted or unsubstituted heterocyclyl;

R 5a is hydrogen, alkyl, haloalkyl, cycloalkyl, phosphonalkyl, (CH 2 ) n C(═O)OR 6 , C(═O)R 6 , C(═O)OR 6 , or C(═O)NR 6 R 7 ;

R 5b is an electron pair or alkyl;

R 6 and R 7 are, at each occurrence, independently hydrogen, alkyl, haloalkyl, cycloalkyl, or arylalkyl;

R 8 is alkyl, haloalkyl, aminylalkyl, substituted or unsubstituted arylalkyl; and

n is 1, 2, 3, 4, 5, 6, 7, or 8, provided that

A) R 5a is alkyl, haloalkyl, cycloalkyl, phosphonalkyl, (CH 2 ) n C(═O)OR 6 , C(═O)R 6 , C(═O)OR 6 , or C(═O)NR 6 R 7 or R 1 is substituted with one or more substituents selected from the group consisting of a substituted heteroaryl, C(═NH)NHC(═O)OR 8 , C(═NOC(═O)R 8 )NH 2 , C(═NOC(═O)OR 8 )NH 2 , and C(═NOH)NH 2 ; and

B) when R 5a is alkyl or (CH 2 ) n C(═O)OR 6 , R 1 does not have the following structure:

unless R 2 and R 3 , together with the carbon and nitrogen to which they are attached, respectively,

form an optionally substituted 4-7 membered heterocyclyl.

2. The compound of claim 1 , wherein R′ is a substituted or unsubstituted phenyl.

3. The compound of claim 1 , wherein R 1 has one of the following structures:

4. The compound of claim 1 , wherein R 1 is a substituted or unsubstituted heteroaryl.

5. The compound of claim 1 , wherein R 1 is substituted with one or more substituents selected from the group consisting of a substituted heteroaryl, C(═NH)NHC(═O)OR 8 , C(═NOC(═O)R 8 )NH 2 , C(═NOC(═O)OR 8 )NH 2 , and C(═NOH)NH 2 .

6. The compound of claim 5 , wherein R 1 is substituted with C(═NH)NHC(═O)OR 8 and R 8 is a substituted or unsubstituted arylalkyl.

7. The compound of claim 5 , wherein R 1 is substituted with C(═NOC(═O)R 8 )NH 2 and R 8 is an aminylalkyl.

8. The compound of claim 5 , wherein R 1 is substituted with C(═NOC(═O)OR 8 )NH 2 and R 8 is an alkyl, a haloalkyl, or a substituted or unsubstituted arylalkyl.

9. The compound of claim 5 , wherein R 1 has one of the following structures:

10. The compound of claim 1 , wherein R 2 is hydrogen or C 1 -C 6 alkyl.

11. The compound of claim 1 , wherein R 2 is —CH 3 .

12. The compound of claim 1 , wherein R 2 and R 3 , together with the carbon and nitrogen to which they are attached, respectively, form an optionally substituted 4, 5, or 6 membered heterocyclyl.

13. The compound of claim 1 , wherein R 4 is a substituted or unsubstituted aryl.

14. The compound of claim 1 , wherein R 4 has one of the following structures:

15. The compound of claim 1 , wherein R 5a is alkyl, C(═O)OR 6 , phosphonalkyl, or (CH 2 ) n C(═O)OR 6 .

16. The compound of claim 15 , wherein R 5a has one of the following structures:

17. The compound of claim 1 , wherein R 5b is an electron pair.

18. The compound of claim 1 , wherein R 5b is alkyl.

19. A compound having one of the structures:

or a stereoisomer, tautomer, or pharmaceutically acceptable salt thereof.

20. A pharmaceutical composition comprising a compound or pharmaceutically acceptable salt thereof of claim 1 and a pharmaceutically acceptable carrier or excipient.

21. A method for treating a MASP-2-associated disease or disorder in a subject in need thereof, the method comprising administering to the subject an effective amount of a compound of claim 1 .
