چکیده انگلیسی
The inhibition of the zinc enzyme carbonic anhydrase (CA, EC 4.2.1.1) with (thio)coumarins has been recently reported (Maresca et al., J. Am. Chem. Soc. 2009, 131, 3057). Here we demonstrate that a series of γ- and δ-(thio)lactones also act as mechanism based, prodrug type CA inhibitors, similar to the (thio)coumarins. Through the esterase activity of CA, these compounds are hydrolyzed in situ to the corresponding hydroxy/keto/mercapto acids which thereafter act as inhibitors. CA isoforms I and IX were efficiently inhibited by simple such compounds, with KIs in the range of 0.92-19.1 μM, whereas CA II was not inhibited at all. Isoform-selective CA inhibitors which spare the ubiquitous off-target CA II may have interesting applications for example for selectively inhibiting the tumor-associated CA IX, a validated anticancer target.
