1-Phenylethanol exists as a solid soluble (in water) and a very weakly acidic compound (based on its pKa).

D-Saccharic acid potassium salt is a compound formed from oxidizing sugars which can be used to test for the presence of hepatic enzyme induction. Studies indicate that D-glucuronolactone dehydrogenase oxidizes D-Saccharic acid potassium salt into D-glucaro-l4;63-dilactone.

Isoquinoline is an analog of pyridine. Isoquinoline-based alkaloids, such as p-tolyl bisisoquinoline, phthaloyl isoquinoline, and naphthyl isoquinoline, exhibit anticancer activity.Berberine, an isoquinoline alkaloid, exerts anti-inflammatory effects in diabetic mice by downregulating the gene expression ratios of pro-/anti-inflammatory and Th1/Th2 cytokines.Additionally, some isoquinoline-based compounds also possess antidepressant, antibacterial, antimalarial, and anti-HIV activities.
