Novel 1-amino-4-(ar)alkylaminoanthraquinone derivatives bearing different substituents (Br, CH2OH, CN, or CH3) at the 2-position of the anthraquinone scaffold were synthesized by copper-catalyzed Ullmann condensation. The 2-substituted 1-amino-4-bromoanthraquinone derivatives (bromaminic acid analogues) were reacted with a variety of alkyl-, aryl-, and aralkylamines. Different reaction conditions were applied depending on the physical state of the amine and the nature of the substituent at the 2-position of the anthraquinone scaffold. A solvent-free synthetic procedure was developed for reactions with liquid amines. Condensation with solid amines required the addition of a solvent, and reaction conditions had to be optimized for each of the anthraquinone derivatives. Our results emphasize that copper-catalyzed reactions are highly variable depending on the molecules and anions present in the medium, since different reaction mechanisms apply. The synthesized anthraquinone derivatives may be useful as new dyes, or may show biological activity and could be employed as tool compounds in experimental pharmacology.

The urokinase receptor (uPAR) serves as a docking site to the serine protease urokinase-type plasminogen activator (uPA) to promote extracellular matrix (ECM) degradation and tumor invasion and metastasis. Previously, we had reported a small molecule inhibitor of the uPAR·uPA interaction that emerged from structure-based virtual screening. Here, we measure the affinity of a large number of derivatives from commercial sources. Synthesis of additional compounds was carried out to probe the role of various groups on the parent compound. Extensive structure-based computational studies suggested a binding mode for these compounds that led to a structure-activity relationship study. Cellular studies in non-small cell lung cancer (NSCLC) cell lines that include A549, H460 and H1299 showed that compounds blocked invasion, migration and adhesion. The effects on invasion of active compounds were consistent with their inhibition of uPA and MMP proteolytic activity. These compounds showed weak cytotoxicity consistent with the confined role of uPAR to metastasis.
