Bifosfonatos (BFs) como transportadores osteotrópicos no planejamento de fármacos dirigidos

Abstract: Recebido em 14/4/03; aceito em 21/10/03 BISPHOSPHONATES AS OSTEOTROPIC CARRIERS FOR DESIGNING SITE-DIRECTED DRUGS. Drug therapy involving bone tissue diseases is difficult, calling for the design of specific drugs. The present paper is a brief review of a new site-directed system termed ODDS (osteotropic drug delivery system), based on a latenciation process, using bisphosphonates as bone carriers. This is an important tool for the rational prodrug design for obtaining selective drugs.Keywords: bisphosphonates… Show more

“…Analysis of variance (ANOVA) and the Tukey test for multiple comparisons were used, considering p<0.05 as signifi cant. Results: There were no signifi cant differences in %ATI/g of the Na 99m TcO 4 in the organs of the groups studied (p>0.05). An increase in the weight of the SB rats was observed after the second postoperative week.…”

“…Além disto, a elevada afinidade dos bisfosfonados pelo tecido ósseo possibilita sua utilização na vetorização de fármacos. Existem relatos do uso de compostos bisfosfônicos como transportadores de várias substâncias direcionadas ao tecido ósseo, tais como radioisótopos utilizados no diagnóstico de tumor osteolítico, agentes antineoplásicos e antiinflamatórios 8 .…”
