The invention features compounds of formulas I or II: and pharmaceutically acceptable salts and prodrugs thereof, as well methods for modulating the effects of local and systemic hypoxic events using the compounds.

This invention relates to compounds which are N-oxides and derivatives thereof, as well as their use to treat HIF related diseases. These compounds have the general formula set out below and are used to treat a variety of diseases associated with HIF:wherein R is an alkyl, aryl, arakyl or derivatives thereof such as CH3OCH2CH2—, CH3CH2OCH2CH2—, C6H5OCH2CH2—, C6H5CH2—, CH3(CH2)3OCH2CH2Cl; or any one of the following:

The present invention relates to compounds suitable for use in mediating hypoxia inducible factor and for treating erythropoietin-associated conditions by increasing endogenous erythropoietin in vitro and in vivo.

The present invention generally relates to the modulation of hypoxia-inducible factor (HIF) using the compounds and methods disclosed herein. These compounds and methods can be applied to the prevention, pretreatment, and / or treatment of conditions or states associated with HIF, such as hypoxia- and ischemia-related conditions and the induction of stasis.

A method is provided for treating mammals, including humans, with advanced or large-tumour burdens. The method involves administering an immunotherapeautic agent in conjunction with a tumour growth restricting agent, in amounts effective to eradicate any advanced or large tumours present. In preferred embodiments, the immunotherapeautic agent comprises a T-cell co-stimulatory cell adhesion molecule (CAM) or a mammalian expression vector containing DNA which encodes a T-cell co-stimulatory CAM, such as B7.1, and the tumour growth restricting agent is flavone acetic acid, 5,6-dimenthyl-xanthenone-4-acetic acid, or an agent which disrupts the expression or activity of hypoxia-inducible factor-1 (HIF-1).

Methods and pharmaceutical compositions for preconditioning and / or providing neuroprotection to the animal central nervous system against the effects of neurological disorders involving ischemia, trauma, metal poisoning and neurodegeneration, including the associated cognitive, behavioral and physical impairments. In one embodiment, the method is accomplished by stimulating and / or stabilizing hypoxia-inducible factor-1α (HIF-1α). HIF-1α is known to provide a neuroprotective benefit under ischemic conditions. In another embodiment, the method is accomplished by differentially reducing, inhibiting or preventing the increased expression of selected genes caused by neurological disorders. Patients at risk for certain diseases or disorders that are associated with risk for cerebral ischemia may benefit, e.g., those at risk for Alzheimer's disease, Parkinson's disease, Wilson's disease, Huntington's disease, thalassemia or stroke, or those patients having head or spinal cord injury. Patients undergoing certain medical procedures that may result in ischemia may also benefit. Initially, the possibility of ischemia or neurodegeneration is recognized. Intranasal therapeutic agents are administered to the upper third of the nasal cavity to bypass the blood-brain barrier and access the central nervous system directly to avoid unwanted and potentially lethal side effects. Therapeutic agents include those substances that interact with iron and / or copper such as iron chelators, copper chelators, and antioxidants. Particular examples of such therapeutic agents are the iron chelators deferoxamine (DFO) and deferasirox. Intranasal administration of DFO is known to stimulate and / or stabilize HIF-1α and provides an efficient and safe method for pre-conditioning the brain to protect against cerebral ischemia.
