Twenty seven derivatives (2-28) of 2-(2-methyl-5-nitro-1H-imidazol-1-yl)ethanol were synthesized and evaluated for anti-trichomonas, spermicidal and antifungal activities. Twenty six compounds were active against Trichomonas vaginalis at MIC ranging from 1-42 μM and seven compounds (9,18,19,22,24,26,28) immobilized 100% human spermatozoa at 1% concentration (w/v). Twenty three compounds (2,3,5,8-26,28) exhibited antifungal activity at 25-50 μg/mL concentration. Seven compounds (9,18,19,22,24,26,28) showed significant anti-trichomonas and spermicidal activities and also exhibited mild antifungal activity. All the compounds were highly safe towards human cervical cell line (HeLa) as shown by the cell-viability assay of HeLa cells at 200 μg/mL concentration, whereas nonoxynol-9 (N-9, the marketed spermicidal microbicide) was highly cytotoxic. Therefore, it may be concluded that introduction of the pharmacophore responsible for spermicidal activity into a proven anti-trichomonas structure may lead to a potent dual function microbicide better and safer than N-9.

Various novel aliphatic and aromatic esters of metronidazole have been synthesized to improve the physicochemical properties (Rm values, lipophilicity) using prodrug approach. The alcoholic functional group of metronidazole is readily esterified, thus several novel ester prodrugs of metronidazole have been synthesized and evaluated for their anaerobic antibacterial activity and mutagenicity. These compounds have been characterized by UV, IR, 1H NMR, mass spectra and elemental analysis. The partition coefficient of esters is determined by n-octanol/water system, RP-TLC and computed in silico. Anaerobic-activity against C. perfringens. determined in terms of MIC (μg/ml) show the esters, particularly SDS-18 and SDS-19, to be more potent in comparison to metronidazole. The Ames test is used to compare the mutagenic potential of the synthesized 5-nitroimidazoles.

Lipophilic metronidazole derivatives and their absorption through hairless mouse skin

Previously we have shown that the diacyl glyceryl ester of naproxen is absorbed into excised mouse skin and slowly degraded to release naproxen. In the present work we have synthesised some organic acid and fatty acid derivatives of metronidazole, and studied the in-vitro degradation in aqueous buffer solutions and serum as well as their permeation through hairless mouse skin. The derivatives were enzymatically degraded in serum to form metronidazole. Only the acetic acid and butyric acid derivatives were able to permeate hairless mouse skin intact. The fatty acid derivatives released metronidazole within the skin. The metronidazole delivery through the skin was significant when the metronidazole oleate was used. This compound could therefore be considered as a suitable pro drug for dermal applications.
