Source: Streptomyces chartreusis
Description: Tunicamycin is a mixture of homologous nucleoside antibiotics.
The main homologs differ in the length of the fatty chain moiety. The following table defines the four main Tunicamycin homologs.

Tunicamycin A, aka Tunicamycin V, n=9, mw=817
Tunicamycin B, aka Tunicamycin VII, n=10, mw=831
Tunicamycin C, aka Tunicamycin II, n=8, mw=845
Tunicamycin D, aka Tunicamycin X, n=11, mw=859
CAS number: 11089-65-9
Merck index: 14, 9819
Molecular weight: 844.4 (for n=10, "Tunicamycin VII")


Molecular Formula: C39H64N4O16 (for n=10, "Tunicamycin VII")
(for n=10, "Tunicamycin VII")
Tunicamycin is soluble in DMSO, alkaline water, hot methanol
Practically insoluble in acetone, ethyl acetate,
Unstable in acidic solutions
Appearance: White crystalline solid.
Purity: At least 98% by TLC, HPLC


(In methanol) 205,260
Melting pointTunicamycin decomposes at 234°C - 235°C
SolubilityClear solution at 50mg/ml of DMSO
ApplicationsTunicamycins inhibit protein glycosylation. They arrest cell cycle in late G1
As Tunicamycin affects cell membrane permeability, it was shown to increase production of antibiotics, such as streptomycin. (1)
WarningsTunicamycin  is potentially harmful or fatal if swallowed, inhaled, or absorbed through the skin.
Classificationnucleoside antibiotic
proteins glucosylation inhibitor
