1-Dodecylimidazole (N-Dodecylimidazole) is a lysosomotropic detergent and a cytotoxic agent. 1-Dodecylimidazole causes cell death by its acid-dependent accumulation in lysosomes, disruption of the lysosomal membrane, and releaseof cysteine proteases into the cytoplasm. 1-Dodecylimidazole has hypocholesterolaemic activity and broad-spectrum antifungal activity[1][2][3].
N-dodecylimidazole, an acid activated detergent with a pKa of 6.3, has been shown to be cytotoxic to cells in culture. N-dodecylimidazole displayed extracellular pH (pHe)-dependent cytotoxicity against EMT-6 and MGH U1 cells. cell killing was dose dependent and was 100-fold greater at pHe 6.0 than pHe 7.0[4].
The hypocholesterolaemic activity of 1-dodecylimidazole results in part from the inhibition of cholesterol biosynthesis at the level of 2,3-oxidosqualene sterol cyclase[2].1-dodecylimidazole (150 mg/kg body wt; by stomach tube; daily for 10 days) has lower serum cholesterol concentrations than control rats[2].

The isolation of 2,3-oxidosqualene from the liver of rats treated with 1-Dodecylimidazole, a novel hypocholesterolaemic agent
Biochem J 1972 Nov;130(1):153-7.PMID:4655417DOI:10.1042/bj1300153.
1. Non-saponifiable lipid from the livers of rats treated with 1-Dodecylimidazole contained an unidentified compound that was not present in the livers from untreated animals. 2. Treated rats had lower serum cholesterol concentrations than control rats. 3. 1-Dodecylimidazole, when added to rat liver slices, inhibited the incorporation of [1-(14)C]acetate and [2-(14)C]mevalonate into digitonin-precipitable sterols and resulted in the accumulation of a labelled compound, which was chromatographically identical with the unknown compound described in 1 above. 4. Rats treated with 1-Dodecylimidazole incorporated less [(14)C]mevalonate into liver digitonin-precipitable sterols than untreated animals and accumulated the unknown compound as a labelled intermediate. 5. The unknown intermediate had the same chromatographic properties, n.m.r. and mass spectra as authentic 2,3-oxidosqualene. 6. The identity of the intermediate as 2,3-oxidosqualene was further established by showing that it was incorporated into sterols by rat liver homogenates under anaerobic conditions. In addition, incubation of [(14)C]squalene with rat liver homogenates resulted in trapping of the radioactivity by the added intermediate. 7. It is suggested that the hypocholesterolaemic activity of 1-Dodecylimidazole results in part from the inhibition of cholesterol biosynthesis at the level of 2,3-oxidosqualene sterol cyclase.
Effects of miconazole and dodecylimidazole on sterol biosynthesis in Ustilago maydis
Antimicrob Agents Chemother 1979 Apr;15(4):603-7.PMID:464593DOI:10.1128/AAC.15.4.603.
Miconazole at minimal fungitoxic concentrations inhibits ergosterol biosynthesis in sporidia of Ustilago maydis by interference with sterol C14 demethylation. The action is analogous to that of the fungicides triarimol and fenarimol. The fungicide 1-Dodecylimidazole at low concentrations (0.1 to 0.25 mug/ml) inhibits sterol C14 demethylation; however, at higher concentrations (1.0 mug/ml or greater) it also inhibits 2,3-oxidosqualene cyclization and subsequent transmethylation. It is postulated that this diversity of effects of 1-Dodecylimidazole results from binding of the inhibitor to sterol carrier protein(s).
Self-organized lipid-porphyrin bilayer membranes in vesicular form: nanostructure, photophysical properties, and dioxygen coordination
Chemistry 2002 Dec 2;8(23):5469-80.PMID:12561319DOI:10.1002/1521-3765(20021202)8:23<5469::AID-CHEM5469>3.0.CO;2-1.
An amphiphilic tetraphenylporphyrin and its iron complex bearing four phospholipid substituents, in which a trimethylolethane residue connects the two acyl chains (lipid-porphyrins), have been synthesized. The free-base lipid-porphyrin 6a self-organizes in aqueous media to form spherical unilamellar vesicles with a diameter of 100 nm and a uniform thickness of 10 nm, which corresponds to twice the length of the molecule. In the visible absorption spectrum, the porphyrin Soret band was significantly red-shifted (12 nm) relative to that of the monomer in benzene/MeOH solution due to the excitonic interaction of the porphyrin chromophores. The [symbol: see text]-A isotherm of 6a gave an area per molecule of 2.2 nm2, which allowed the estimation of the number of molecules in a single vesicle (2.3 x 10(4)). Double-layered Langmuir-Blodgett (LB) films of 6a on a glass surface exhibited an absorption spectrum identical to that of the 6a vesicles in bulk aqueous solution, and this suggests that they contain similar geometric arrangements of the porphyrin moieties. Exciton calculations on the basis of our structural model reproduced the bathochromic shift of the Soret band well. In the photophysical properties of the 6a vesicles, the characteristics of J-aggregated porphyrins substantially predominate: strong fluorescence and extremely short triplet lifetime. The iron complex 6b with a small molar excess of 1-Dodecylimidazole (DIm) also formed spherical unilamellar vesicles (100 nm phi). Scanning force microscopy after evaporation on a graphite surface revealed 6b/DIm vesicles with a vertical height of 19.8 nm, which coincided with the thickness of the double bilayer membranes. The ferrous 6c formed a bis(DIm)-coordinated low-spin FeII complex under an N2 atmosphere. Upon addition of O2 to this solution, a kinetically stable O2 adduct was formed at 37 degrees C with a half-life of 17 h. Distinct gel-phase (liquid-crystal) transitions of the lipid-porphyrin membranes were clearly observed; the free base 6a displayed a higher transition temperature (56 degrees C) than the iron complex. Magnetic circular dichroism and infrared spectroscopic studies proved that molecular O2 coordinates to the self-organized lipid-porphyrinatoiron(II) vesicles in aqueous media.
