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].

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
