Synthesis of Salicylate and Salicylamide Alcohols for the Preparation of Phosphorodiamidates and Ifosfamide Prodrugs.

Abstract

Pro drugs are derivatives of drug substance which gives parent drug or release drug when it breaks inside the body by the presence of suitable enzyme,and then exert desired pharmacological effect. For many years, prodrug strategy has been developed enormously to solve many unwanted drug properties. In drug discovery and development, prodrugsare well-known pharmacokinetic effects of pharmacologically nimbleproducts. Almost10% of drugs permitted whole worldare classified as prodrugs, where the application of a prodrug method duringinitial stages of drug development is an emergent fashion. Phosphorodiamidates prodrugs are well known anticancer agents particularly against leucomia. To improve the selectivity of the chemotherapeutic agents and reduce systemic toxicity, I herein report different types of salicylate and salicylamide alcohols for the preparation of phosphorodiamidates and ifosfamide prodrugs.
