cancer cells, especially complex 3 which is 8 times more active than cisplatin. No hydrolysis was observed by NMR and UV-Vis for complexes 3 and 6; however, these complexes show big differences in nucleobase binding, mainly decided by the imionopyridine chelating ligand. Complex 3 is stable in the presence of glutathione, but 6 reacted rapidly with glutathione. The octanol/water partition coefficients

compounds, but there is a lack of efficient methods for their synthesis. We report a convenient and efficient route to these privileged structures starting from easily accessible 2-substituted pyridines and aryne precursors. A small library of compounds has been synthesized utilizing the developed method, affording variouslysubstituted pyrido[1,2-a]indoles in moderate to good yields.

salutary effects of low doses of carbon monoxide (CO) has spurred interest in designing exogenous molecules that can deliver CO to biologicaltargets under controlled conditions. Herein we report a water-soluble photosensitive manganese carbonyl complex [MnBr(CO)3(pyTAm)] (2) (pyTAm = 2-(pyridyl)imino-triazaadamantane) that can be triggered to releaseCO upon exposure to visible light. Inclusion of a
