An electrospray mass spectrometric method for the quantification of the depolarizing neuromuscular blocking agent succinylcholine (SUX) is described. An extraction method compatible with direct infusion inlet was developed and leads to an analysis cycle time of 7--8 min instead of 25 min that would be required for HPLC inlet. SUX was extracted from human(More)
Leishmania, the causative agent of various forms of leishmaniasis, is the significant cause of morbidity and mortality. Regarding energy metabolism, which is an essential factor for the survival, parasites adapt to the environment under low oxygen tension in the host using metabolic systems which are very different from that of the host mammals. We carried(More)
BACKGROUND Among the factors influencing the onset of action of neuromuscular blocking agents (NMBA), the potency (EC50) and the rate of equilibration between blood and the effect compartment (k(e0)) have been highlighted. Although these descriptors are intrinsically influenced by the physicochemical characteristics of the drug, the impact of lipid(More)
Leishmaniasis is a growing health problem in many parts of the world partly due to drug resistance of the parasite. This study reports on the fisibility of studying mitochondrial properties of two forms of wild-type L. donovani through the use of selective inhibitors. Amastigote forms of L. donovani exhibited a wide range of sensitivities to these(More)
A series of 3-substituted amino-4,5-tetramethylene thieno[2,3-d] [1,2,3]-triazine-4(3H)-ones have been synthesized and characterized by UV,IR, 1H NMR, elemental and mass spectral analysis. The title compounds were evaluated for their antimicrobial activity by agar diffusion method against four bacteria and three fungi using Ampicillin and Miconazole nitrate(More)
