Doxycycline-d3 (hyclate)

Doxycycline-d3 is intended for use as an internal standard for the quantification of doxycycline (Cay-14422) by GC- or LC-MS. Doxycycline is a broad-spectrum tetracycline antibiotic. It inhibits bacterial protein synthesis by binding to ribosomes. Doxycycline also selectively inhibits human matrix metalloproteinase-8 (MMP-8) and MMP-13 over MMP-1 with 50, 60, and 5% inhibition, respectively, when used at a concentration of 30 µM. It can be used as a regulator for inducible gene expression systems where expression depends on either the presence (Tet-On) or absence (Tet-Off) of doxycycline. Formulations containing doxycycline have been used in the treatment of bacterial infections and the prevention of malaria.Formal Name: (4S,4aR,5S,5aR,6R,12aS)-4-(dimethylamino)-1,4,4a,5,5a,6,11,12a-octahydro-3,5,10,12,12a-pentahydroxy-(6-methyl-d)-1,11-dioxo-2-naphthacene-4,6-d2-carboxamide, hydrochloride, compd. with ethanol, hydrate (2:2:1:X).
