X 14868A

The Uses of X 14868A

Maduramicin is a polyether antibiotic first isolated from Actinomadura yunnaense (formerly Nocardia sp. X-14868) in 1963. Maduramicin is a broad spectrum anticoccidial also active against Treponema and Cryptosporidium. Maduramicin is an ionophore, forming complexes with monovalent cations, with a higher affinity for K+ than Na+. Maduramicin is used as the ammonium salt in animals to prevent coccidiosis and to promote growth.

Maduramicin is a broad-spectrum anticoccidial

Biological Activity

maduramicin, a natural polyether antibiotic, is cytotoxic against cryptosporidium spp. and plasmodium gametocytes, isolated from the actinomycete actinomadura rubra. as a broad-spectrum anticoccidial, maduramicin, which is commonly used in veterinary medicine as an anti-coccidial agent, is active against treponema and cryptosporidium. maduramicin is an ionophore which can form complexes with monovalent cations with a higher affinity for k+ than na+.

in vitro

maduramicin concentration-dependently blocked cell growth and inhibited cell proliferation in a concentration- and time-dependent fashion in skeletal muscle cells, mouse myoblasts (c2c12) and human rhabdomyosarcoma (rd and rh30) cells. also, maduramicin triggered cleavage of poly adp ribose polymerase in a concentration-dependent manner, which was the hallmark of caspase-dependent apoptosis in c2c12 and rd cells. it was determined that maduramicin caused cell death via caspase-dependent and -independent manner in c2c12 cells [2].

in vivo

severe combined immune deficient (scid) mice were administered with maduramicin at 3 mg/kg of body weight per day by oral gavage for 28 days. maduramicin treatment decreased the fecal parasite load after 21 days of treatment. also, maduramicin treatment elicited weight loss in scid mice. in addition, maduramicin exerted remarkable anticryptosporidial activities with concomitant moderate toxicity on scid mice [3].
