A pilot study was conducted in 23 patients in order to assess the correlation between docetaxel clearance (CL) and pharmacokinetics of dexamethasone. Dexamethasone is mainly 6-β hydroxylated by CYP3A4, and is regularly used as standard docetaxel premedication. Genotyping of known functional single nucleotide polymorphism (SNP) of CYP3A5 (G22893A) and mdr-1(More)
Proliferative vitreoretinopathy (PVR), the most serious complication causing retinal detachment surgery to fail, is one of the leading causes of vision-loss in developed countries. The pharmaceutical treatment of this disease, located in the posterior segment of the eye, is problematic because it is difficult to achieve effective drug levels in the vitreous(More)
Tartrate resistant acid phosphatase (TRAP) is considered as an enzyme marker for osteoclasts and their precursors. A cytomorphometric study of the osteoclastic population was made after TRAP staining on transiliac bone biopsies from 10 human volunteers, and the diameter of each TRAP positive profile was determined with an automatic image analyser. The(More)
In this paper, we evaluate the potential use of theoretical calculations to obtain an energy scale of the lowest ligand-centred triplet excited state in luminescent terbium(III) complexes. In these complexes, non-radiative deactivation of the terbium emitting state via a back-energy transfer process (T1<--Tb(5D4)) is a common quenching process. Consequently(More)
Various alkylcarbonyloxymethyl esters of nalidixic acid ranging from 3 to 15 carbon units in the pro-moiety have been prepared and assessed as potential prodrugs. Their chromatographic retention factors k', silicone oil solubilities and in vitro conversion to nalidixic acid by a commercial esterase were determined together with their in vitro antimicrobial(More)
The synthesis of C-7/C-7-linked ciprofloxacin (CP) and C-6/C-6-linked levofloxacin (LV) derivatives with modulated lipophilicity is described herein. The synthesized compounds, along with the monomeric analogs described previously, were evaluated in vitro for (i) their growth inhibitory effect against five human cancer cell lines, (ii) their antibacterial(More)
Ciprofloxacin (CP), an antibiotic has been shown to have antiproliferative and apoptotic activities in several cancer cell lines. Moreover, several reports have highlighted the interest of increasing the lipophilicity to improve the antitumor efficacy. These studies have led us to synthesize new CP derivatives of various lipophilicities and to evaluate(More)
A convenient route for the synthesis of some acyloxymethyl esters and carboxamides of levofloxacin (LV) with modulated lipophilicity is described. The synthesized compounds were evaluated in vitro for their growth inhibitory effect in five human cancer cell lines. The most efficient LV derivatives (ester 2e and amide 4d) displayed IC(50) values in the(More)
A method for checking the purity of N-acyl aminonaphthalene disulphonic acid derivatives was required for a systematic study of the anti-human immunodeficiency virus activity of these agents. We describe the use of thin-layer chromatography and flame ionization detection for the separation of these compounds, which are difficult to analyse by conventional(More)
