The objective of this study was to design new nitroimidazole-based derivatives as strong urease inhibitors for the treatment of H. pylori infections. New series of nitroimidazole derivatives, 4a–k, were synthesized by using TBTU as the catalyst and assaye

Two series of compounds with hydrazone derivatives (HZ1-HZl2, series 1) and oxadiazoline derivatives (OZ1-OZ12, series 2) of the 2-methyl-5-nitro-1H- imidazole scaffold were designed and synthesized. Physicochemical properties and Lipophilic efficiency (LipE) analysis predicted higher intrinsic quality of the acylhydrazone derivatives (series 1) than their corresponding oxadiazoline analogues (series 2). In vitro antiamoebic results supported the above findings and validated that the acylhydrazone derivatives (HZ1-HZl2) show better activity than the oxadiazoline derivatives (OZ1-OZ12). MTT assay, using HepG2 cell line, revealed noncytotoxic nature of the compounds. The most promising results were observed for compounds HZ5 (IC50 = 0.96 μM) and HZ9 (IC 50 = 0.81 μM) both in silico and in vitro. Analysis of the Lipophilic efficiency (LipE) of the compounds provided new insight for the design of potent and selective amoebicides.

A new ligand (2-methyl-5-nitro-1-imidazomethyl)-1,3,4-oxadiazole- 2-thione (L) and its Ag(I),Cu(II) and Zn(II) complexes were synthesized. The authenticity of the ligand and its transition metal complexes were established by elemental analyses, conductance and magnetic susceptibility measurements, as well as spectroscopic (IR, 1H NMR, electronic, mass and ESR) and thermal studies. The IR spectral studies revealed the existence thiol-thione tautamerism in the ligand molecule. The magnetic and electronic spectral studies suggest an octahedral geometry for Cu(II) and Zn(II) complexes. The ligand acts as a bidentate coordinating through the N-3 nitrogen and the exocyclic sulfur atoms of oxadiazole rings. Antimicrobial screening of the ligand and its metal complexes were determined against the bacteria Escherichia coli and Salmonella paratyphi A.

(Chemical Equation Presented) Oxidation of metronidazole (4) with sodium dichromate yielded the corresponding 2-(2-methyl-5-nitro-1H-imidazol-1-yl)acetic acid (5) which was esterified with 1-butanol to give butyl 2-(2-methyl-5-nitro- 1H-imidazol-1-yl)acetate (8). Reaction of the latter with hydrazine hydrate gave 2-(2-methyl-5-nitro-1H-imidazol-1-yl)acetohydrazide (9). Compound 5-[(2-methyl-5-nitro-1H-imidazol-1-yl)methyl]-1,3,4-oxadiazole-2(3H)-thione (10) could be obtained through the reaction of compound 9 with carbon disulfide in basic medium. Subsequent alkylation of compound 10 afforded alkyl 2-(5-[(2-methyl-5-nitro-1H-imidazol-1-yl)methyl]-1,3,4-oxadiazol-2-ylthio) acetate (11) in good yield. Reaction of hydrazide 9 with substituted isothiocynate yielded 1-[2-(2-methyl-5-nitro-1H-imidazol-1-yl)acetyl]-4-aryl(or ethyl)thiosemicarbazide (12) which was cyclized in acidic media to N-substituted 2-amino-5-[(2-methyl-5-nitro-1H-imidazol-1-yl)methyl]-1,3,4-thiadiazole (13).

A new series of 1,3,4-oxadiazoline derivatives 5a-1 have been obtained by cyclisation of various hyerazones 4 with acetic anhydride. The hydrazones 4 in turn are obtained by the reaction of appropriate carbonyl compound with 2-methyl-5-nitroimidazole-1-acethydrazide 3. The new products are characterized by spectral and analytical data. Most of the tested compounds show promising antibacterial and antifungal activity.
