Alkylation of sodium diethyldithiocarbamate with allyl-2-chloroacetate, allyl-3-chloropropionate, chloromethyl-2-(tetrahydrofuran-2-yl)acetate, and 4-(chloromethyl)-1,3-dioxolane in the aqueous medium synthesized functionally substituted esters of N, N-dietyleditiocarbamic acid (M1-M4). Most active compounds were docked into the catalytic active site of the enzyme. We identified that acetate moiety for inhibition of hCA I, hCA II, and α-glycosidase and dioxolane and thiocarbamic acid moieties for inhibition of AChE and BChE enzymes are very important. The hCA I isoform was inhibited by these novel functionally substituted esters based on sodium diethyldithiocarbamate derivatives (M1-M4) in low micromolar levels, the Ki of which differed between 48.03 ± 9.77 and 188.42 ± 46.08 µM. Against the physiologically dominant isoform hCA II, the novel compounds demonstrated Kis varying from 57.33 ± 6.21 to 174.34 ± 40.72 µM. Also, these novel derivatives (M1-M4) effectively inhibited AChE, with Ki values in the range of 115.42 ± 12.44 to 243.22 ± 43.65 µM. For BChE Ki values were found in the range of 94.33 ± 9.14 to 189.45 ± 35.88 µM. For α-glycosidase the most effective Ki values of M4 and M3 were with Ki values of 32.86 ± 7.88 and 37.63 ± 4.08 µM, respectively.
