Abstract: A method of treating a cancer in a mammalian subject afflicted with the cancer, includes administering to the subject an immune checkpoint inhibitor, and administering to the subject a pentaaza macrocyclic ring complex corresponding to the formula (I) below, prior to, concomitantly with, or after administration of the immune checkpoint inhibitor, to increase the response of the cancer to the immune checkpoint inhibitor.

Abstract: Aspects of the present disclosure relate to compounds which have enhanced oral bioavailability. A transition metal complex includes a transition metal coordinated by a macrocycle comprising the pentaaza 15-membered macrocyclic ring corresponding to Formula A and two axial ligands having the formula —OC(O)X1. each of the two axial ligands has the formula —OC(?O)X1 wherein each X1 is independently substituted or unsubstituted phenyl or —C(—X2)(—X3)(—X4); each X2 is independently substituted or unsubstituted phenyl, or substituted or unsubstituted alkyl; each X3 is independently hydrogen, hydroxyl, alkyl, amino, —X5C(?O)R13 where X5 is NH or O, and R13 is C1-C18 alkyl, substituted or unsubstituted aryl or C1-C18 aralkyl, or —OR14, where R14 is C1-C18 alkyl, substituted or unsubstituted aryl or C1-C18 aralkyl, or together with X4 is (?O); and each X4 is independently hydrogen or together with X3 is (?O).

Abstract: The present invention relates to compounds which are effective as catalysts for dismutating superoxide and, more particularly, the manganese or iron complexes of substituted, unsaturated heterocyclic 16-membered macrocyclic complexes that catalytically dismutate superoxide. It also relates to methods of using these complexes to reduce the concentration or the effects of superoxide, pharmaceutical compositions comprising these compounds or their metal complexes, and methods of treating conditions associated with excessive superoxide activity.

Abstract: The present disclosure relates to methods of treating cancers that are responsive to antimetabolite or antimitotic anti-cancer agents. The methods involve the use of at least one anti-cancer agent selected from antimetabolite anti-cancer agents, antimitotic anti-cancer agents, and combinations thereof, and a superoxide dismutase mimetic to potentiate the therapeutic effect of the anti cancer agent(s).
