Metronidazole (Mz)-resistant Giardia and Trichomonas were inhibited by 1 of 30 new 5-nitroimidazole drugs. Another five drugs were effective against some but not all of the Mz-resistant parasites. This study provides the incentive for the continued design of 5-nitroimidazole drugs to bypass cross-resistance among established 5-nitromidazole antiparasitic(More)
Hemolytic uremic syndrome is a rare disease, frequently responsible for renal insufficiency in children. Recent findings have led to renewed interest in this pathology. The discovery of new gene mutations in the atypical form of HUS and the experimental data suggesting the involvement of the complement pathway in the typical form, open new perspectives for(More)
To improve the antiparasitic pharmacophore, 20 5-nitroimidazoles bearing an arylsulfonylmethyl group were prepared from commercial imidazoles. The antiparasitic activity of these molecules was assessed against Trichomonas vaginalis, the in vitro cytotoxicity was evaluated on human monocytes and the mutagenicity was determined by the Salmonella mutagenicity(More)
Since 1976, fibrin glues have been attracting medical interest, spreading from their initial use as a hemostatic agent in cardiovascular surgery to other fields of surgery. Studies have compared the efficacy of fibrin glues vs sutures in surgery. However, few comparisons have been made of the efficacy and safety of the different fibrin glues commercially(More)
The synthesis of β-carbolines and their in vitro antiplasmodial and antileishmanial activities were described herein. These molecules have also been studied concerning their in vitro cytotoxicity toward the human cell line THP1, in order to calculate their respective selectivity indexes (SI). Among the 20 tested molecules, four exhibited significant(More)
Experimentally, superoxide dismutase (SOD) protects against cytotoxological and histotoxological effects of superoxide anions, which play a fundamental role where inflammatory processes are involved. Currently, only bovine copper containing SOD (Cu-SOD) is available for clinical application in the treatment of patients with various arthritic diseases. The(More)
Paclitaxel and docetaxel are established as the standards of care, either as monotherapy or in combination with other cytotoxic agents in metastasic breast cancer. In order to improve the efficiency of solvent-based paclitaxel and to overcome its drawbacks in terms of safety, a solvent-free formulation has been developed. This work is a review of the(More)
The 5-nitroimidazole (NI) compound C17, with a side chain carrying a remote phenyl group in the 2-position of the imidazole ring, is at least 14-fold more active against the gut protozoan parasite Giardialamblia than the 5-NI drug metronidazole (MTR), with a side chain in the 1-position of the imidazole ring, which is the primary drug for the treatment of(More)
The efficacies of 12 5-nitroimidazole compounds and 1 previously described lactam-substituted nitroimidazole with antiparasitic activity, synthesized via SRN1 and subsequent reactions, were assayed against the protozoan parasites Giardia duodenalis, Trichomonas vaginalis, and Entamoeba histolytica. Two metronidazole-sensitive lines and two(More)
1,3-Diphenylpyrazole-4-carboxaldehyde and 1-(4-nitrophenyl)-3-phenylpyrazole-4-carboxaldehyde were obtained from the appropriated phenylhydrazones via the Vilsmeier-Haack reaction. These two aldehydes were functionalized by various substituted anilines or substituted benzylamines. Antiparasitic activities of the corresponding azomethines were assessed. In(More)
