Carbonic anhydrases (CAs, EC 4.2.1.1) had six genetically distinct families described to date in various organisms. There are 16 known CA isoforms in humans. Human CA isoenzymes I and II (hCA I and hCA II) are ubiquitous cytosolic isoforms. Acetylcholine esterase (AChE. EC 3.1.1.7) is a hydrolase that hydrolyzes the neurotransmitter acetylcholine relaying the signal from the nerve. In this study, some trimethoxyindane derivatives were investigated as inhibitors against the cytosolic hCA I and II isoenzymes, and AChE enzyme. Both hCA isozymes were inhibited by trimethoxyindane derivatives in the low nanomolar range. These compounds were good hCA I inhibitors (Kis in the range of 1.66-4.14 nM) and hCA II inhibitors (Kis of 1.37-3.12 nM) and perfect AChE inhibitors (Kis in the range of 1.87-7.53 nM) compared to acetazolamide as CA inhibitor (Ki: 6.76 nM for hCA I and Ki: 5.85 nM for hCA II) and Tacrine as AChE inhibitor (Ki: 7.64 nM).

2-(Methacryloyloxy)ethyl 6-methyl-2-oxo-4-phenyl-1,2,3,4-tetrahydropyrimidine-5-carboxylate, is a cyclic urea derivative synthesized from urea, 2-(methacryloyloxy) ethyl acetoacetate and substituted benzaldehyde, and tested in terms of the inhibition of two physiologically relevant carbonic anhydrase (CA) isozymes I and II. Acetylcholinesterase (AChE) is found in high concentrations in the red blood cells and brain. Butyrylcholinesterase (BChE) is another enzyme abundantly present in the liver and released into blood in a soluble form. Also, they were tested for the inhibition of

“…In this study, both hCA I, and II isoenzymes were purified by Sepharose-4B-L-tyrosine-sulfanilamide affinity chromatography [63][64][65] . The affinity chromatography consists Sepharose-4B-L-tyrosine-sulfanilamide that acts as affinity matrix for selective retention of CA isoenzymes [66][67][68] . The column material was prepared according to a previous method 69 .…”

A series of diaryl ethers were synthesized and their human (h) carbonic anhydrase (CA) isoenzymes hCA I and II, acetylcholinesterase (AChE), and butyrylcholinesterase (BuChE) inhibitory actions were investigated. The new compounds were synthesized from the corresponding phenols and bromobenzenes via the Ullmann reaction, by using dipicolinic acid as a copper (I) complexing ligand. hCA I and II were inhibited with K i s in the low nanomolar range of 102.01-127.13 nM against hCA I, and of 73.71-113.40 nM against hCA II, whereas the inhibition constants against AChE were of 15.35-18.34 nM and against BChE in the range of 9.07-22.90 nM. The CA inhibition mechanism with these ethers is unknown, but may be similar to that of aryl methyl ethers investigated earlier by computational approaches.
