Investigation of inhibitory properties of some hydrazone compounds on hCA I, hCA II and AChE enzymes

Recently, inhibition of carbonic anhydrase (hCA) and acetylcholinesterase (AChE) have appeared as a promising approach for pharmacological intervention in a variety of disorders such as glaucoma, epilepsy, obesity, cancer, and Alzheimer's disease. Keeping this in mind, N,N′-bis[(1-aryl-3-heteroaryl)propylidene]hydrazine dihydrochlorides, N1-N11, P1, P4-P8, and R1-R6, were synthesized to investigate their inhibitory activity against hCA I, hCA II, and AChE enzymes. All compounds in N, P, and R-series inhibited hCAs (I and II) and AChE more efficiently than the reference compounds acetazolamide (AZA), and tacrine. According to the activity results, the most effective inhibitory compounds were in R-series with the Ki values of 203 ± 55–473 ± 67 nM and 200 ± 34–419 ± 94 nM on hCA I, and hCA II, respectively. N,N′-Bis[1-(4-fluorophenyl)-3-(morpholine-4-yl)propylidene]hydrazine dihydrochlorides, N8, in N-series, N,N′-Bis[1-(4-hydroxyphenyl)-3-(piperidine-1-yl)propylidene]hydrazine dihydrochlorides, P4, in P-series, and N,N′-bis[1-(4-chlorophenyl)-3-(pyrrolidine-1-yl)propylidene]hydrazine dihydrochlorides, R5, in R-series were the most powerful compounds against hCA I with the Ki values of 438 ± 65 nM, 344 ± 64 nM, and 203 ± 55 nM, respectively. Similarly, N8, P4, and R5 efficiently inhibited hCA II isoenzyme with the Ki values of 405 ± 60 nM, 327 ± 80 nM, and 200 ± 34 nM, respectively. On the other hand, P-series compounds had notable inhibitory effect against AChE than the reference compound tacrine and the Ki values were between 66 ± 20 nM and 128 ± 36 nM. N,N′-Bis[1-(4-fluorophenyl)-3-(piperidine-1-yl)propylidene]hydrazine dihydrochlorides, P7, was the most potent compound on AChE with the Ki value of 66 ± 20 nM. The other most promising compounds, N,N′-bis[1-(4-hydroxyphenyl)-3-(morpholine-4-yl)propylidene]hydrazine dihydrochlorides, N4 in N-series and N,N′-bis[1-(4-hydroxyphenyl)-3-(pyrrolidine-1-yl)propylidene]hydrazine dihydrochlorides, R4 in R-series were againts AChE with the Ki values of 119 ± 20 nM, 88 ± 14 nM, respectively.

Cytotoxicity of hydrazones of morpholine bearing mannich bases towards Huh7 and T47D cell lines and their effects on mitochondrial respiration

N,N'-bis[1-(substitutedphenyl)-3-(morpholine-4-yl)propylidene]hydrazine dihydrochlorides, N1-N11 were designed and synthesized as cytotoxic agents. These compounds were synthesized by the reaction of 2 moles of 1-(substitutedphenyl)-3-(morpholine-4-yl)-1-propanone hydrochlorides with 1 mole of hydrazine hydrate. The compounds reported here are new, except N1 and N4. The cytotoxicity of the compounds was tested against human hepatoma (Huh7) and breast cancer (T47D) cell lines. 5-Fluorouracil (5-FU) was used as a reference compound. It was found that N3, which has 4-methoxy substituent on phenyl ring, was the most cytotoxic compound towards both cell lines. Its cytotoxicity was 5.6 times higher than 5-FU. Representative compounds N2 at 144, 264 and 424 μM and N3 at 401 μM concentrations significantly inhibited mitochondrial respiration in a dose dependent manner in liver homogenates. This suggests that the inhibition of mitochondrial respiration may be one of the contributing mechanisms to the cytotoxicity of the compounds. N3 may serve as a candidate compound for further studies.
