  • Publication number: 20110172214
    Abstract: Provided herein are compositions and related methods useful for free radical scavenging, with particular selectivity for mitochondria. The compounds comprise a nitroxide-containing group attached to a mitochondria-targeting group. The compounds can be cross-linked into dimers without loss of activity. Also provided herein are methods, for preventing, mitigating and treating damage caused by radiation. The method comprises delivering a compound, as described herein, to a patient in an amount and dosage regimen effective to prevent, mitigate or treat damage caused by radiation.

  • Publication number: 20110039792
    Abstract: The present invention provides a composition and related methods for delivering cargo to a mitochondria which includes (a) a membrane active peptidyl fragment having a high affinity with the mitochondria and (b) cargo. The cargo may be selected from a wide variety of desired cargos which are to be delivered to the mitochondria for a specific purpose. Compositions and methods are disclosed for treating an illness that is caused or associated with cellular damage or dysfunction which is caused by excessive mitochondrial production of reaction oxygen species (ROS). Compositions which act as mitochondria-selective targeting agents using the structural signaling of the ?-turn recognizable by cells as mitochondria) targeting sequences are discussed. Mitochondria and cell death by way of apoptosis is inhibited as a result of the ROS-scavenging activity, thereby increasing the survival rate of the patient.

Compositions which act as mitochondria-selective targeting agents using specific structural signaling features recognizable by cells as mitochondrial targeting sequences are discussed. A method for delivering these agents effectively into cells and mitochondria where they act as electron scavengers by way of certain targeting sequences is also disclosed. Mitochondria dysfunction and cell death by way of apoptosis is inhibited as a result of the ROS-scavenging activity, thereby increasing the survival rate of the patient. In a preferred embodiment, the compositions and methods may be administered therapeutically in the field to patients with profound hemorrhagic shock so that survival could be prolonged until it is feasible to obtain surgical control of the bleeding vessels.
