In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Reversal Agent and Linker Variants of Reversed Chloroquines: Activities against Plasmodium falciparum, published in 2010-01-28, which mentions a compound: 837-52-5, Name is 7-Chloro-4-(piperazin-1-yl)quinoline, Molecular C13H14ClN3, Application of 837-52-5.
We have shown that “”reversed chloroquine mols.”” constructed from chloroquine-like and resistance “”reversal-agent””-like cores can be powerful drugs against malaria. Several reversed chloroquines are now presented that probe parameters governing the activities against chloroquine-resistant and chloroquine-sensitive malaria strains. The design is tolerant to linker and reversal agent changes, but a piperazinyl group adjacent to the quinoline, at least for the group of compounds studied here, may be detrimental.
Compounds in my other articles are similar to this one(7-Chloro-4-(piperazin-1-yl)quinoline)Application of 837-52-5, you can compare them to see their pros and cons in some ways,such as convenient, effective and so on.
