5-Bromo-8-nitroisoquinoline (cas: 63927-23-1) belongs to isoquinoline derivatives. Isoquinoline is a structural isomer of quinoline, which have antiseptic, antipyretic and anti-cyclic properties, and can be used as antimalarial drugs and for the preparation of other antimalarial medicine. The Pomeranz–Fritsch reaction provides a method for the preparation of isoquinoline. This reaction uses a benzaldehyde and aminoacetoaldehyde diethyl acetal, which in an acid medium react to form isoquinoline.COA of Formula: C9H5BrN2O2

Synthesis and Radioligand Binding Studies of C-5- and C-8-Substituted 1-(3,4-Dimethoxybenzyl)-2,2-dimethyl-1,2,3,4-tetrahydroisoquinoliniums as SK Channel Blockers Related to N-Methyl-laudanosine and N-Methyl-noscapine was written by Graulich, Amaury;Scuvee-Moreau, Jacqueline;Seutin, Vincent;Liegeois, Jean-Francois. And the article was included in Journal of Medicinal Chemistry in 2005.COA of Formula: C9H5BrN2O2 This article mentions the following:

The synthesis and the 125I-apamin binding studies of some C(5)- and C(8)-substituted 1-(3,4-dimethoxybenzyl)-2,2-dimethyl-1,2,3,4-tetrahydroisoquinoliniums and 1-(3,4-dimethoxybenzyl)-6,6-dimethyl-4,5,6,7-tetrahydrothieno[2,3-c]pyridiniums were performed in order to find a reversible and selective SK channel blocker structurally related to N-methyllaudanosine and N-methylnoscapine. A bulky alkyl substituent in the C-8 position of the tetrahydroisoquinoline produces a clear increase in the affinity for the apamin sensitive binding sites. The presence of an electron-withdrawing group in the C-5 and C-8 positions is not a suitable substitution for the affinity of drugs structurally related to N-methyl-laudanosine. Thiophene analogs and 8-methoxy derivatives possess a poor affinity for the apamin sensitive binding sites. Electrophysiol. studies performed with the most effective compound showed a blockade of the apamin sensitive afterhyperpolarization in rat dopaminergic neurons. In the experiment, the researchers used many compounds, for example, 5-Bromo-8-nitroisoquinoline (cas: 63927-23-1COA of Formula: C9H5BrN2O2).
