Therapeutic targets for hydrogen sulfide (H2S). An abundance of experimental evidence suggests that H2S plays a prominent role in normal physiology and pathophysiology. Therefore, many therapeutic targets exist for H2S therapy, including cancer, heart failure, organ transplant, peripheral artery disease, inflammatory bowel disease, Alzheimer's disease, acute myocardial infarction (MI), stroke, atherosclerosis, hypertension, erectile dysfunction, metabolic syndrome, diabetes, and thrombosis.
