  A wide variety of new bi(hetero)aryl derivatives of the thieno[3,2-b]pyridine skeleton was obtained in high to excellent yields (65-91%) by Suzuki-Miyaura cross-coupling of the methyl 3-amino-6-bromothieno[3,2-b]pyridine-2-carboxylate, recently reported by us, with aryl or heteroaryl pinacolboranes or potassium trifluoroborates.The coupling products obtained were evaluated for their growth inhibitory effect on three human tumor cell lines, representing different tumor models, MCF-7 (breast adenocarcinoma), A375-05 (melanoma) and NCI-H460 (non-small cell lung cancer). Some of the compounds showed an interesting activity against the tested cell lines, with GI(50) values in the mu M range, and it was possible to establish some structure activity relationships (SARs). Several compounds presented GI(50) values below 15 MM, particularly a bithiophene and an o-aniline thienopyridine derivative. The first presented selectivity for MCF-7 and NCI-H460 cell lines, with very low GI(50) values (0.7-1.0 mu M), while the latter was active against the three cell lines tested in this study, also presenting very low GI(50) values (2.5-4.2 mu M). The effect of these two compounds on cell cycle progression was analyzed in the NCI-H460 cell line. Results showed that both compounds interfered with the normal cell cycle distribution.

  di(hetero)arylamines were obtained by C–N Buchwald–Hartwig coupling with bromonitrobenzenes and with 2-bromopyridine. In the latter case a tetracyclic compound was formed by intramolecular cyclization. Using a brominated derivative in the pyridine ring as a coupling component, it was possible to synthesize C–C (Suzuki and Sonogashira) and C–N (Buchwald–Hartwig) coupling products and a tetracyclic compound obtained
