In vitro and in vivo characterization of a new organic nitrate hybrid drug covalently bound to pioglitazone.
<b><i>Background/Aims:</i></b> Organic nitrates represent a group of nitrovasodilators that are clinically used for the treatment of ischemic heart disease. The new compound CLC-3000 is an aminoethyl nitrate (AEN) derivative of pioglitazone, a thiazolidinedione antidiabetic agent combining the peroxisome proliferator-activated receptor &#947; agonist activity of pioglitazone with the NO-donating activity of the nitrate moiety. <b><i>Methods:</i></b> In vitro and in vivo characterization was performed by isometric tension recording, platelet function, bleeding time and detection of oxidative stress. <b><i>Results:</i></…
Characterization of New Organic Nitrate Hybrid Drugs Covalently Bound to Valsartan and Cilostazol
Background and Purpose: Organic nitrates represent a group of nitrovasodilators that are clinically used for the treatment of ischemic heart disease. With the present studies we synthesized and characterized new organic nitrate hybrid molecules. Compounds CLC-1265 (valsartan mononitrate) and CLC-1280 (valsartan dinitrate) are derivatives of the angiotensin receptor blocker valsartan, with CLC-1265 containing a single organic nitrate linker and CLC-1280 also containing a second, different linker. Compounds CLC-2000 (cilostazol mononitrate) and CLC-2100 (cilostazol dinitrate) are nitrate derivatives of the phosphodiesterase III inhibitor cilostazol. All compounds are designed as hybrid molecu…
