A series of new quinoline derivatives was designed, synthesized and evaluated as potential antitumor agents. The results indicated that most compounds exhibited potent antiproliferative activity, and 7-(4-fluorobenzyloxy)–N-(2-(dimethylamino)- ethyl)quinolin-4-amine 10g was found to be the most potent antiproliferative agent against human tumor cell lines with an IC50 value of less than 1.0 μM. Preliminary structure-activity relationships analysis suggested that (1) the large and bulky alkoxy substituent in position-7 might be a beneficial pharmacophoric group for antiproliferative activity; (2) the amino side chain substituents in position-4 facilitated the antiproliferative activity of this class of compounds; and (3) the length of the alkylamino side chain moiety affected the antiproliferative potency, with two CH2 units being the most favorable. Further investigation of the mechanism of action of this class of compounds demonstrated that the representative compound 10g triggered p53/Bax-dependent colorectal cancer cell apoptosis by activating p53 transcriptional activity. Moreover, the results showed that compound 10g effectively inhibited tumor growth in a colorectal cancer xenograft model in nude mice. Thus, these quinoline derivatives might serve as candidates for the development of new antitumor drugs.

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.
