Reactivity parameters in structure-activity relationship-based risk assessment of chemicals. [PDF]
New approaches to the risk assessment process are needed that might be more definitive and satisfying to the scientific community, interest groups, and the public at large. This commentary examines an alternative approach that is based on understanding the relationships of chemical structure and reactivity properties to the toxicokinetic behavior of ...

Naphthoquinone derivatives exert their antitrypanosomal activity via a multi-target mechanism [PDF]
Recently, we reported on a new class of naphthoquinone derivatives showing a promising anti-trypanosomatid profile in cell-based experiments. The lead of this series (B6, 2-phenoxy-1,4-naphthoquinone) showed an ED(50) of 80 nM against Trypanosoma brucei ...

Gibbs Free-Energy-Based Objective Function for Electrolyte Activity Coefficient Models
This paper proposes Gibbs free-energy-based objective functions in the parameter fitting of activity coefficient and specific heat capacity of ions. The activity coefficient parameters are fitted through the averaged squared error between the Gibbs free ...
