In silico fasciolicide activity of three experimental compounds in sheep.

The aim of the present study was to evaluate the fasciolicide activity of three experimental drugs, selected by an in silico system called TOMOCOMD-CARDD, in sheep. Drugs were identified by the computer system, and, after statistical selection, 24 Pelibuey sheep were infected on days 0 and 30, each with 200 metacercariae of Fasciola hepatica. When the infection reached 8 and 4 weeks of age, respectively, four groups of six animals each were formed.

Paramphistomum spp: improved artificial excystment and in vitro culture of immature and adult stages.

The aims of the present study were to establish an adequate excystment method for metacercariae of Paramphistomum spp. and to compare the in vitro survival of paramphistomids in three different culture media. In a preliminary study, 31 different assays were performed solely with the purpose of obtaining the best percentage of metacercariae excystment.

TOMOCOMD-CARDD, a novel approach for computer-aided 'rational' drug design: I. Theoretical and experimental assessment of a promising method for computational screening and in silico design of new anthelmintic compounds.

In this work, the TOMOCOMD-CARDD approach has been applied to estimate the anthelmintic activity. Total and local (both atom and atom-type) quadratic indices and linear discriminant analysis were used to obtain a quantitative model that discriminates between anthelmintic and non-anthelmintic drug-like compounds. The obtained model correctly classified 90.

Atom, atom-type and total molecular linear indices as a promising approach for bioorganic and medicinal chemistry: theoretical and experimental assessment of a novel method for virtual screening and rational design of new lead anthelmintic.

Helminth infections are a medical problem in the world nowadays. In this paper a novel atom-level chemical descriptor has been applied to estimate the anthelmintic activity. Total and local linear indices and linear discriminant analysis were used to obtain a quantitative model that discriminates between anthelmintic and non-anthelmintic drug-like compounds.
