New types of nonexplosive O-2-sulfonylethyl protected (-CH2CH2SO2R; R = OMe, NHOMe, NHOBn, Me) derivatives of isopropylamine diazen-1-ium-1,2-diolate (IPA/NO) (2-5) were developed that are designed to act as novel HNO donors. These compounds, with suitable half lives (6.6-17.1 h) at pH 7.4, undergo a base induced beta-elimination reaction that releases a methyl vinyl sulfone product and the, parent IPA/NO anion which subsequently preferentially releases HNO (46-61% range). Importantly, the O-2-methylsulfonylethyl compound 5 exhibited a significant in vitro inotropic effect up to 283% of the baseline value and increased the rates of contraction and relaxation but did not induce a chronotropic effect. Furthermore; compound 5 (22.5 mg/kg po dose). provided a significant reduction in blood pressure up to 6 h after drug administration. All these data suggest that O-2-sulfonylethyl protected derivatives of IPA/NO, which are efficient HNO donors, could have potential applications to treat cardiovascular disease(s) such as congestive heart failure.

Structural modifications of nonsteroidal anti-inflammatory drugs (NSAIDs) have successfully reduced the side effect of gastrointestinal ulceration without affecting anti-inflammatory activity, but they may increase the risk of myocardial infarction with chronic use. The fact that nitroxyl (HNO) reduces platelet aggregation, preconditions against myocardial infarction, and enhances contractility led us to synthesize a diazeniumdiolate-based HNO-releasing aspirin and to compare it to an NO-releasing analogue. Here, the decomposition mechanisms are described for these compounds. In addition to protection against stomach ulceration, these prodrugs exhibited significantly enhanced cytotoxcity compared to either aspirin or the parent diazeniumdiolate toward nonsmall cell lung carcinoma cells (A549), but they were not appreciably toxic toward endothelial cells (HUVECs). The HNO-NSAID prodrug inhibited cylcooxgenase-2 and glyceraldehyde 3-phosphate dehydrogenase activity and triggered significant sarcomere shortening on murine ventricular myocytes compared to control. Together, these anti-inflammatory, antineoplasic, and contractile properties suggest the potential of HNO-NSAIDs in the treatment of inflammation, cancer, or heart failure.

The present disclosure provides methods utilizing the diazeniumdiolate-based prodrugs for the treatment of cancer via various mechanisms and procedures. The disclosure also provides kits comprising the diazeniumdiolate-based prodrugs. Despite the fact that there have been significant developments in anti-cancer technology, such as radiotherapy, chemotherapy and hormone therapy, cancer still remains the second leading cause of death following heart disease in the United States. Most often, cancer is treated with chemotherapy utilizing highly potent drugs.
