Present invention describes the obtainment of new compounds, synthesized in the form of homodimeric, heterodimeric, and/or homo and heteromultimeric pro-drugs, which present activity of phosphodiesterasis inhibition, being useful for the treatment of diseases and dysfunctions mediated by this class of enzyme or where the inhibition of these enzymes cause the desired therapeutic effects.
These compounds, sinthesized as pro-drugs, are activated by the organism by means of natural biochemical processes, being this activation effected by means of cleavage of their labile bond bridges. The availability of the active drugs, derivative of these pro-drugs, is made in a natural way in the organism, positively influencing on its effect, increasing the bioavailability of these active drugs, being this increment followed by decreased side effects, due to the reduced degradation of the active drugs by the pre-systemic metabolism.
                            本发明描述了通过合成同源二聚体、异源二聚体和/或同种异聚物前药形式的新化合物的获得,这些化合物表现出
磷酸二酯酶抑制活性,对于治疗由该类酶介导的疾病和功能障碍或抑制这些酶引起所需的治疗效果是有用的。这些作为前药合成的化合物通过自然的生化过程被机体激活,这种激活是通过其不稳定的键桥的断裂来实现的。这些前药的衍
生物的有效药物的可用性以一种自然的方式在机体中进行,从而积极地影响其效果,增加这些有效药物的
生物利用度,这种增加随着副作用的减少而进行,由于通过前系统代谢降解了有效药物。
