Although it has not been extensively studied, a significant volume of literature suggests that TREK2 will probably turn out to be an important channel in charge of tuning neuronal transmitter and hormone levels. Thus, pharmacological tools which can manipulate this channel, such as selective agonists are essential both in drug design and to further our understanding of this system. Our investigations have shown that sulfonate ('O') chalcone and sulfonamide ('N') chalcones regulate the TREK2 channel in remarkably different ways: sulfonamide chalcone 5 behaved as an inhibitor with an IC(50) of 62 mu M, whereas the sulfonate analogue 11 activated TREK2 with EC(50) value of 167 mu M.

Diseases affecting cardiovascular system are ranked as a top most cause of morbidity and mortality. Herein, a novel class sulphonamides‐1,3,5‐triazine conjugates have been synthesized and tested for inhibitory activity against MMP‐2 and MMP‐9. The results of the study showed that these molecules efficiently inhibit MMP‐9 than MMP‐2, revealing compound 8e as the most potent inhibitor (IC50 = 2.34 ± 0.56 nm). Due to involvement of MMP‐9 in many cardiovascular diseases, particularly in myocardial ischaemia (MI), compound 8e was further subjected for the determination of the protective effect on isoproterenol (ISO)‐induced myocardial injury in rats.
