Design of Barbiturate–Nitrate Hybrids that Inhibit MMP-9 Activity and Secretion
摘要:
We describe a new type of barbiturate-based matrix metalloproteinase (MMP) inhibitor incorporating a nitric oxide (NO) donor/mimetic group (series 1). The compounds were designed to inhibit MMP at enzyme level and to attenuate MMP-9 secretion arising from inflammatory signaling. To detect effects related to the nitrate, we prepared and studied an analogous series of barbiturate C5-alkyl alcohols that were unable to release NO (series 2). Both series inhibited recombinant human MMP-2/9 activity with nanomolar potency. Series 1 consistently inhibited the secretion of MMP-9 from TNF alpha/IL1 beta stimulated Caco-2 cells at 10 mu M, which could be attributed to NO related effects because the non-nitrate panel did not affect enzyme levels. Several compounds from series 1 (10 mu M) inhibited tumor cell invasion but none from the non-nitrate panel did. The work shows that MMP-inhibitory barbiturates are suitable scaffolds for hybrid design, targeting additional facets of MMP pathophysiology, with potential to improve risk-benefit ratios.

compounds potentially capable of releasing both aspirin and nitric oxide in vivo. A series of nitrate-bearing alkyl esters of aspirin were prepared based on the choline ester template preferred by human plasma butyrylcholinesterase. The degradation kinetics of the compounds were followed in human plasma solution. All compounds underwent hydrolysis rapidly (t(1/2) approximately 1min) but generating
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.
