What is PUROMYCIN DIHYDROCHLORIDE?
Description
Puromycin (58-58-2) is an aminonucleoside antibiotic derived from Streptomyces alboniger. It is a protein synthesis inhibitor that disrupts peptide transfer on ribosomes causing premature chain termination.1 It is an inhibitor of dipeptidyl-peptidase II and cytosolic alanyl aminopeptidase.2 Puromycin also inhibits protein transport in mitochondria.3

The Uses of PUROMYCIN DIHYDROCHLORIDE
Puromycin dihydrochloride is the salt of puromycin, a nucleoside antibiotic isolated from Streptomyces alboniger in the 1950s as an anti-trypansomal agent with antibiotic activity. While the salt shares the same pharmacological properties as puromycin free base, its greater water solubility offers advantages in some in vitro applications. Physicochemical properties and chromatographic behaviour will depend on whether the pH is buffered. In non-pH controlled systems, the free base and salt may behave differently.
The Uses of PUROMYCIN DIHYDROCHLORIDE
Puromycin is an aminonucleoside antibitotic. Puromycin acts as a protein synthesis inhibitor which interferes with translation by inhibiting ribosome functions. Puromycin is also a reversible inhibitor of dipeptidyl-peptidase II (serine peptidase) and cytosol alanyl aminopeptidase.

Purification Methods
Puromycin dihydrochloride is purified by recrystallisation from H2O. The free base, [58-60-6] M 294.3, has m 175.5-177o (172-173o) (from H2O). The sulfate has m 180-187o dec (from H2O), and the picrate monohydrate has m 146-149o (from H2O). [Baker et al. J Am Chem Soc 77 1 1955, Fryth et al. J Am Chem Soc 80 3736 1958.] It is an inhibitor of aminopeptidase and terminates protein synthesis [Reboud et al. Biochemistry 20 5281 1981]. [Beilstein 26 III/IV 3704.]
