Disclosed herein are napthamide and quinoline carboxamide compounds containing two bicyclic moieties, pharmaceutical compositions comprising those compounds and methods of using the compositions in the treatment of cancers mediated by cyclic-AMP (cAMP) response element binding protein (CREB). The disclosed compositions have utility in the treatment of lung, prostate and breast cancers in a human subject.
solubility of 666-15, amino esterprodrugs 1 and 4 were designed and synthesized. Detailed chemical and biological studies of 1 and 4 revealed that a small portion of the prodrugs were converted into 666-15 through intermediate 3 instead of a long-range O,N-acyl transfer reaction that was initially proposed. These results provide unique insights into the activation of these esterprodrugs.

Recent studies have shown that nuclear transcription factor cyclic adenosine monophosphate response element binding protein (CREB) is overexpressed in many different types of cancers. Therefore, CREB has been pursued as a novel cancer therapeutic target. Naphthol AS-E and its closely related derivatives have been shown to inhibit CREB-mediated gene transcription and cancer cell growth. Previously, we identified naphthamide 3a as a different chemotype to inhibit CREB's transcription activity. In a continuing effort to discover more potent CREB inhibitors, a series of structural congeners of 3a was designed and synthesized. Biological evaluations of these compounds uncovered compound 3i (666-15) as a potent and selective inhibitor of CREB-mediated gene transcription (IC50 = 0.081 +/- 0.04 mu M). 666-15 also potently inhibited cancer cell growth without harming normal cells. In an in vivo MDA-MB-468 xenograft model, 666-15 completely suppressed the tumor growth without overt toxicity. These results further support the potential of CREB as a valuable cancer drug target.

CREB (cANIP response element binding protein) has been shown to play an important role in tumor initiation, progression, and metastasis. We discovered that naphthol AS-E, a cell-permeable CREB inhibitor, presented antiproliferative activity in a broad panel of cancer cell lines in vitro. However, it has limited aqueous solubility. In this report, we described a water-soluble inhibitor (compound 6) of CREB-mediated gene transcription with in vivo anticancer activity. Unexpectedly, compound 6 was found to be a prodrug of compound 12 necessitating an unprecedented long-range O,Nacyl transfer. The rate of this transfer was pH- and temperature-dependent. To the best of our knowledge, this is the first time to show that a long-range O,N-acyl transfer could be exploited as a prodrug activation strategy to improve aqueous solubility. This type of prodrug may be applicable to other structures with spatially arranged hydroxyl amide to improve their aqueous solubility.
