General Description

Quinolinic acid, 2-methyl ester is a chemical compound that is derived from quinolinic acid, which is a byproduct of the kynurenine pathway in the body. It is a neuroactive compound that has been implicated in various neurological and neurodegenerative disorders, including Alzheimer's disease, Parkinson's disease, and schizophrenia. The 2-methyl ester derivative of quinolinic acid has been studied for its potential role as a biomarker for these conditions, as well as for its potential therapeutic applications. Additionally, it has been investigated for its activity in the central nervous system and its potential involvement in neuroinflammation and excitotoxicity. Further research is needed to fully understand the impact of quinolinic acid, 2-methyl ester on neurological function and its potential as a target for therapeutic intervention in various neurological disorders.

Investigation of the Structure-Activity Relationships of Aza-A-Ring Indenoisoquinoline Topoisomerase i Poisons

Several indenoisoquinolines have shown promise as anticancer agents in clinical trials. Incorporation of a nitrogen atom into the indenoisoquinoline scaffold offers the possibility of favorably modulating ligand-binding site interactions, physicochemical properties, and biological activities. Four series of aza-A-ring indenoisoquinolines were synthesized in which the nitrogen atom was systematically rotated through positions 1, 2, 3, and 4. The resulting compounds were tested to establish the optimal nitrogen position for topoisomerase IB (Top1) enzyme poisoning activity and cytotoxicity to human cancer cells. The 4-aza compounds were the most likely to yield derivatives with high Top1 inhibitory activity. However, the relationship between structure and cytotoxicity was more complicated since the potency was influenced strongly by the side chains on the lactam nitrogen. The most cytotoxic azaindenoisoquinolines 45 and 46 had nitrogen in the 2- or 3-positions and a 3′-dimethylaminopropyl side chain, and they had MGM GI50 values that were slightly better than the corresponding indenoisoquinoline 64.
