Silver(I) compounds are well known for their pharmacological applications as antibiotics and have been also evaluated potential anticancer agents. The use of simple silver(I) salts, such AgNO3, an antimicrobial agent, has limited due to the formation AgCl precipitate under physiological conditions, preventing a major part Ag(I) ions reach infected site. On other hand, slow maintainable release ion into cell or tissue could be achieved by its administration in form complexes. Among different...
