Abstract

The present invention provides small molecule inhibitors of BMP signaling. These compounds may be used to modulate cell growth, differentiation, proliferation, and apoptosis, and thus may be useful for treating diseases or conditions associated with BMP signaling, including inflammation, cardiovascular disease, hematological disease, cancer, and bone disorders, as well as for modulating cellular differentiation and/or proliferation. These compounds may also be used to reduce circulating levels of ApoB-100 or LDL and treat or prevent acquired or congenital hypercholesterolemia or hyperlipoproteinemia; diseases, disorders, or syndromes associated with defects in lipid absorption or metabolism; or diseases, disorders, or syndromes caused by hyperlipidemia.

provided that:
no more than three of A, B, E, G, J, K, and M are N,
at least one of E and M is N, and
that if G, J, K, and M are absent, then the carbon atom drawn as connected to variable M is optionally substituted with R 16 ;

R 3 is selected from H, halogen, cyano, and substituted or unsubstituted alkyl, cycloalkyl, acylamino, carbamate, sulfonyl, sulfoxido, sulfamoyl, and sulfonamido;
R 4 is selected from hydroxyl, carboxyl, and substituted or unsubstituted alkenyl, alkynyl, cycloalkyl, heterocyclyl, aryl, heteroaryl, acyl, ester, alkoxyl, alkylthio, acyloxy, amino, acylamino, carbamate, amido, amidino, sulfonyl, sulfoxido, sulfamoyl, and sulfonamido;
R 15 , independently for each occurrence, is selected from H, halogen, cyano, and substituted or unsubstituted alkyl, cycloalkyl, heterocyclyl, cycloalkylalkyl, heterocyclylalkyl, acylamino, carbamate, sulfonyl, sulfoxido, sulfamoyl, and sulfonamido; and
R 16 , independently for each occurrence, is absent or is selected from H, OH, halogen, cyano, carboxyl, and substituted or unsubstituted alkyl, alkenyl, alkynyl, aralkyl, cycloalkyl, heterocyclyl, aryl, heteroaryl, heteroaralkyl, cycloalkylalkyl, heterocyclylalkyl, acyl, ester, alkoxy, alkylthio, acyloxy, amino, acylamino, carbamate, amido, amidino, sulfonyl, sulfoxido, sulfamoyl, and sulfonamide;
provided that:
i) if Ar is a phenyl ring, it is substituted with at least one non-protium ( 1 H) substituent;
ii) B is C—R 25 when E is N, or K is C—R 25 when M is N, or both, such that at least one of B and K is C—R 25 , wherein
R 25 is selected from deuterium, halogen, hydroxyl, lower alkyl, and lower alkoxy; and/or

iii) R 4 is

W is N, CH, or CCH 3 ;
R 5 is selected from H and substituted or unsubstituted alkyl, acyl, and ester; and
R 6 and R 7 are each independently H or alkyl, or
R 6 forms a one- or two-carbon bridge to the carbon atom adjacent to R 7 and NR 5 ;
wherein either W is CH or CCH 3 , or R 6 and R 7 are not both H.

2. The compound according to claim 1 , wherein B is C—R 25 when E is N, or K is C—R 25 when M is N, or both, such that at least one of B and K is C—R 25 , wherein R 25 is selected from deuterium, fluorine, chlorine, methyl, ethyl, hydroxy, and methoxy.

3. The compound of claim 1 , wherein Ar is a substituted or unsubstituted nitrogen-containing heteroaryl group selected from pyridine, pyrazine, pyrimidine, oxazole, thiazole, thiadiazole and substituted or unsubstituted:

4. The compound of claim 1 , wherein when Ar is substituted, the substituent is selected from deuterium, halogen, hydroxy, cyano, lower alkyl, and lower alkoxy.

5. The compound of claim 1 , wherein Ar is a substituted or unsubstituted six-membered ring.

6. The compound of claim 5 , wherein:
