This paper presents synthesis of novel decorated isoquinolines that can be used as antimalarial agents. Two series of compounds, isoquinoline phenyl and isoquinoline triazole derivatives, were synthesized via the Suzuki–Miyaura and Sharpless–Fokin reactions respectively. The final compounds were investigated for their antimalarialactivity in cell-based experiments. In the series of isoquinoline phenyl

A facile synthetic approach to the direct preparation of 2-pyridyl and 3-pyridylzinc bromides has been demonstrated usingRieke zinc with 2-bromopyridine and 3-bromopyridine, respectively. A variety of different electrophiles have been coupled with the resulting organozinc reagents to give the corresponding cross-coupling products in moderate to good yields.
In this study, two series of simplified isoquinolines deriving from lophocladine B were synthesized and evaluated for their antitumor activity. Suzuki-Miyaura and Sharpelss-Fokin reactions were employed to synthesize 26 compounds. Two compounds (25 and 27) showed to be cytotoxic with IC50 values of 10 µM on hepatic cancer cells and 13 µM on cervical cancer cells, respectively. Further studies on their
