Strategies that promote selective activation of prodrugs by enzymes can be divided into two major classes: 1) deliver of a monoclonal antibody-enzyme immunoconjugate that can recognize a specific antigen and promote the prodrug to a citotoxic drug, with a high selectivity for the target cells, and 2) selective gene delivery encoding an enzyme that can promote the prodrug to a citotoxic drug for the target cells. In this article are discussed ADEPT (antibody-directed enzyme prodrug therapy), GDEPT (gene-directed enzyme prodrug therapy), VDEPT (virus-directed enzyme prodrug therapy), GPAT (genetic prodrug activation therapy) and PDEPT (polymer-directed enzyme prodrug therapy) approaches, their clinical trials, advantages, disadvantages and perspectives.

Angiotensin is an important peptide of renin-angiotensin-aldosterone system. This peptide has an important function on arterial blood pressure regulation and body fluid homeostasis. However, its action on abnormal conditions causes deleterious effects on the cardiovascular system. Vascular resistance, hypertension, vascular and myocytes hipertrophy, production of free radicals and pro-inflammatory substances are some of the actions of angiotensin II that can result on cardiovascular remodeling. Angiotensinconverting enzyme (ACE) inhibitors, angiotensin receptors antagonists, antiinflammatories and antioxidants are used clinically and/or experimentally to prevent or reduce the effects of angiotensin II. The purpose of this work is to review the actions and interactions of angiotensin II on the cardiovascular system, as well as the therapeutic measures employed for the control of these effects.
