Abstract: The present invention provides a process for nitrating aromatic compounds without the need for a solid catalyst and/or any organic solvents and/or any other additives. A typical process includes combining or admixing a nitric acid and an anhydride compound under conditions sufficient to produce a reactive intermediate. The aromatic compound to be nitrated is then added to this reactive intermediate to produce a nitroaromatic compound. The nitroaromatic compound can be substituted with one or more, typically, one to three, and often one or two nitrate (—NO2) groups.

Abstract: Biomodulators, which regulate cellular differentiation and proliferation, as well as methods of use thereof, e.g., for treating various conditions, e.g., cancer, senescence, immunological disorders and vascular disease; for stimulating normal tissue architecture after injury; for vaccination; for stimulating the production of biologically important molecules by cells or organs in culture; for maintaining organs or tissues outside of a body after removal from the body and prior to transplantation; and for producing of vascular grafts for transplantation; are provided.
