5'-Uridylic acid. A uracil nucleotide containing one phosphate group esterified to the sugar moiety in the 2' 3' or 5' position. Uridine 5'-monophosphate is a nucleotide that is found in RNA. It is an ester of phosphoric acid with the nucleoside uridine. UMP consists of the phosphate group the pentose sugar ribose and the nucleobase uracil.

5-CFDA(5-Carboxyfluorescein diacetate) is membrane-permeant. It can be loaded into cells via incubation and hydrolyzed by intracellular esterases to 5-carboxyfluorescein that is used for labeling human intervertebral disk cells in vitro for fluorescence microscopy.

Tarasaponin VI is isolated from Aralia elata with potent inhibitory activity on ethanol absorption.
