Sulfamates have a large spectrum of biological activities including enzyme inhibition. Eight sulfamates derived from menthol (2a–h) were synthesized. Also, in the other section of this study, novel sulfamate derivatives of menthol were tested against some metabolic enzymes including acetylcholinesterase (AChE), butyrylcholinesterase (BChE), and carbonic anhydrase I and II enzymes (hCAs I and II). The newly synthesized novel menthol sulfamate and menthol carbonyl sulfamate derivatives showed K_i values in the range of 34.37 ± 8.17 to 53.40 ± 10.61 nM against hCA I, 12.91 ± 4.57 to 38.67 ± 6.22 nM against hCA II, 111.17 ± 52.36 to 522.86 ± 120.08 nM against AChE, and 50.01 ± 11.73 to 109.63 ± 50.08 nM against BChE. As a result, the novel menthol sulfamate and menthol carbonyl sulfamate derivatives can be promising Alzheimer's disease drug candidates and novel hCA I and hCA II enzymes inhibitors.
