A combination of: a first tetracycline (TC) component; and a second component capable of releasing nitric oxide (NO) or a nitrate capable of mimicking NO effects in vivo (NO mimetic). The combinations of the invention advantageously act as more effective MMP modulators with selective reductions in circulating MMP-9 levels in-vivo and inhibitory effects on MMP-2 and MMP-9 levels in-vitro. The combinations of the invention also advantageously act as modulators of inflammation mediators. The co-existence of abnormalities of MMP enzymes and inflammation in many diseases make these characteristics advantageous. Therefore, the various combinations of the invention find utility in medical applications where MMPs and/or inflammation is implicated.
一种组合物:第一
四环素(TC)组分;以及能释放
一氧化氮(NO)或在体内模拟NO效应的
硝酸盐(NO模拟物)的第二组分。本发明的组合物有利地作为更有效的MMP调节剂,能在体内选择性降低循环MMP-9
水平,并在体外对MMP-2和MMP-9
水平具有抑制作用。本发明的组合物还有利地作为炎症介质的调节剂。在许多疾病中MMP酶和炎症的异常共存使得这些特性具有优势。因此,本发明的各种组合物在医学应用中具有用途,特别是在MMP和/或炎症被牵涉的情况下。
