2-methoxy-3-isobutylpyrazine · 3-isobutyl-2-methoxypyrazine
3-Isobutyl-2-methoxypyrazine (2-isobutyl-3-methoxypyrazine also known as Grindstaff pyrazine) is a methoxypyrazine that is very similar to isopropyl methoxy pyrazine except that the alkyl side-group contains an isobutyl group attached to the carbon alpha to the methoxy sidegroup instead of an isopropyl side-group at that same carbon position.
4-Aminoquinoline is a form of aminoquinoline with the amino group at the 4-position of the quinoline. A variety of derivatives of 4-aminoquinoline are antimalarial agents useful in treating erythrocytic plasmodial infections. Examples include amodiaquine, chloroquine, and hydroxychloroquine.
