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 two of A, B, E, F, G and K are N;
R 3 is selected from H and substituted or unsubstituted alkyl, cycloalkyl, halogen, acylamino, carbamate, cyano, sulfonyl, sulfoxido, sulfamoyl, or sulfonamido;
R 4 is selected from H and substituted or unsubstituted alkenyl, alkynyl, cycloalkyl, heterocyclyl, aryl, heteroaryl, acyl, carboxyl, ester, hydroxyl, alkoxyl, alkylthio, acyloxy, amino, acylamino, carbamate, amido, amidino, sulfonyl, sulfoxido, sulfamoyl, or sulfonamido;
R 15 , independently for each occurrence, is selected from H and substituted or unsubstituted alkyl, cycloalkyl, heterocyclyl, cycloalkylalkyl, heterocyclylalkyl, halogen, acylamino, carbamate, cyano, sulfonyl, sulfoxido, sulfamoyl, or sulfonamido;
R 16 , independently for each occurrence, is absent or is selected from H and substituted or unsubstituted alkyl, alkenyl, alkynyl, aralkyl, cycloalkyl, heterocyclyl, aryl, heteroaryl, heteroaralkyl, cycloalkylalkyl, heterocyclylalkyl, halogen, acyl, carboxyl, ester, hydroxyl, alkoxyl, alkylthio, acyloxy, amino, acylamino, carbamate, amido, amidino, cyano, sulfonyl, sulfoxido, sulfamoyl, or sulfonamido,

with the proviso that the following compound is excluded:

2 . The compound of claim 1 , wherein A, B, E, F, G and K are each CR 16 , preferably CH.

3 . The compound of claim 1 , wherein R 4 is selected from H and substituted or unsubstituted cycloalkyl, heterocyclyl, aryl, heteroaryl, acyl, carboxyl, amino, acylamino, carbamate, amido, amidino, or sulfonamide.

4 . The compound of claim 1 , wherein R 4 is selected from

wherein
W is absent or is C(R 21 ) 2 , O, or NR 21 ;
R 20 is absent or is selected from substituted or unsubstituted alkyl, aralkyl, cycloalkyl, heterocyclyl, aryl, heteroaryl, heteroaralkyl, cycloalkylalkyl, heterocyclylalkyl, acyl, sulfonyl, sulfoxido, sulfamoyl, and sulfonamido; and
R 21 , independently for each occurrence, is selected from H and substituted or unsubstituted alkyl, aralkyl, cycloalkyl, heterocyclyl, aryl, heteroaryl, heteroaralkyl, cycloalkylalkyl, heterocyclylalkyl, acyl, sulfonyl, sulfamoyl, or sulfonamido.

5 . (canceled)

6 . The compound of claim 1 , wherein L 1 is disposed on the para-position of Ar relative to the bicyclic core.

7 . (canceled)

8 . The compound of claim 1 , wherein L 1 has a structure

wherein
Q is selected from CR 10 R 11 , NR 12 , O, S, S(O), and SO 2 ; and
R 10 and R 11 , independently for each occurrence, are selected from H and substituted or unsubstituted alkyl, cycloalkyl, heterocyclyl, cycloalkylalkyl, heterocyclylalkyl, amino, acylamino, carbamate, amido, amidino, cyano, sulfonyl, sulfoxido, sulfamoyl, or sulfonamido;
R 12 selected from H and substituted or unsubstituted alkyl, cycloalkyl, heterocyclyl, heterocyclylalkyl, amino, acylamino, carbamate, amido, amidino, sulfonyl, sulfamoyl, or sulfonamido and
n is an integer from 0-4.

9 . The compound of claim 1 , wherein, when L 1 is absent,
R 4 is selected from H and substituted or unsubstituted alkenyl, alkynyl, cycloalkyl, heterocyclyl, aryl, heteroaryl, acyl, carboxyl, ester, alkylthio, acyloxy, amino, acylamino, carbamate, amido, amidino, sulfonyl, sulfoxido, sulfamoyl, or sulfonamide.

10 . (canceled)

11 . The compound of claim 1 having the structure:

or a pharmaceutically acceptable salt thereof.

12 . A pharmaceutical composition comprising a compound of claim 1 and a pharmaceutically acceptable excipient or solvent.

13 . A method of reducing circulating levels of ApoB-100 or LDL in a subject, comprising administering an effective amount of a compound of claim 1 .

14 . A method of treating hypercholesterolemia, hyperlipidemia, or hyperlipoproteinemia in a subject, comprising administering an effective amount of a compound of claim 1 .

15 . (canceled)
