A series of indazolo[4,3-gh]isoquinolinones derivatives have been synthesized to decrease cardiotoxic side effects in comparison to Mitoxantrone. The antiproliferative effects of different side chains were investigated and tested on at least four different cell lines of cervix, ovarian, CNS, NSCLC (non-small-cell lung cancer) and colon carcinoma. In addition to antiproliferative activities, influence on cell cycle and intercalation behavior have been tested.

Deprotonation of all isomeric lithium pyridinecarboxylates and subsequent trapping with hexachloroethane or iodine afforded straightforward access to chloro- and iodopyridinecarboxylic acids, respectively. Starting from lithium 5-bromonicotinate, the introduction of an iodine atom at C4 and further halogen migration allowed the potential of this method to be extended to the synthesis of more elaborate derivatives.
Application of organolithium compounds in organic synthesis. Part 19. Synthetic strategies based on aromatic metallation. A concise regiospecific synthesis of 3-halogenated picolinic and isonicotinic acids

, p. 1075 - 1086 (2007/10/03)
The synthesis of the halogenated picolin- and isonicotinalides (3) and (4) via metallation (n-BuLi) of the anilides (1) and (2) and then the reaction of the generated bis-lithiated anilides with halogenating agents (CCl3-CCl3, CH2Br-CH2Br, I2) followed by subsequent acidic hydrolysis of (3) and (4), as a way of regiospecific transformation of picoline and isonicotine acids into their C3-halogenated derivatives, is described.
