Synthesis of hydrazinyl-thiazole ester derivatives, trypanocidal and leishmanicidal activities.

To synthesize novel more potent trypanocidal and leishmanicidal agents. Hantzsch's synthetic strategy was used to synthesize 1,3-thiazole-4-carboxylates and their -benzylated derivatives. 28 new thiazole-carboxylates and their -benzylated derivatives were established to test their trypanocidal and leishmanicidal activities.

Pesticide dermal absorption: Case study x in vitro study.

In order to evaluate dermal absorption during typical working conditions in family farming, the amount of dimethoate on clothing and in the stratum corneum (SC) was measured in three rural workers. This was achieved by using cotton patches on the worker's clothes and SC quantification by the tape stripping approach. To mimic the above study, an in vitro approach was performed using Franz cells by applying dimethoate (0.

Dried Blood Spot Technique-Based Liquid Chromatography-Tandem Mass Spectrometry Method as a Simple Alternative for Benznidazole Pharmacokinetic Assessment.

Chagas disease (CD) is recognized as one of the major neglected global tropical diseases. Benznidazole (BNZ) is the drug of choice for the treatment of adults, young infants, and newborns with CD. However, the pharmacokinetics (PK) of BNZ have been poorly evaluated in all age groups, with consequent gaps in knowledge about PK-pharmacodynamic relationships in CD.
