Novel approach to pro-drugs of lactones: water soluble imidate and ortho-ester derivatives of a furanone-based COX-2 selective inhibitor

Interest in water soluble COX-2 inhibitors that can be administered intravenously led to the development of novel pro-drugs of a furanone based COX-2 inhibitor 2. Transforming the lactone moiety of the furanone to an imidate or an ortho-ester with a hydrophilic, endogenous appendage resulted in water soluble pro-drugs that converted to the parent drug in vivo.

Diabetic Cardiomyopathy: A Forensic Perspective

Diabetes mellitus is a common condition affecting both adults and children. Long-standing diabetes is associated with cardiovascular abnormalities such as coronary artery atherosclerosis, microvascular changes, hypertension, kidney disease, and heart failure. Its association with heart failure in the absence of coronary artery disease and hypertension was termed diabetic cardiomyopathy in the 1970s and is believed to account for some of the cardiac mortality in diabetic patients. This entity may be implicated as the cause of sudden cardiac death in the small percentage of diabetic patients in which the autopsy fails to demonstrate evidence of nonketotic hyperosmolar coma, diabetic ketoacidosis, or atherosclerotic and hypertensive cardiovascular disease. Molecular and metabolic alterations have been studied to explain the pathophysiology of this disease.
