Recent developments in the use and abuse of growth promoters

During the last few years, control within the European Union (EU) for illegal growth promoters in cattle and pigs revealed only a limited number of positives. Analysis of illegal preparations, however, showed that steroids, often (esters of) natural hormones, and beta-agonists are still used. Corticosteroids, controlled to a much lesser extent, seem to have become the most important group, while even thyreostats remain. Alarming information was obtained from specific investigations in which a large variety of products were found, some of which had never been reported to be misused in the field of growth promotion. For beta-agonists and quinoxaline compounds, analogues of known compounds are synthesised. Other compounds are readily available as they are registered as growth promoters in some countries outside Europe or are allowed for specific veterinary purposes. Some classes of veterinary drugs are misused for their secondary pharmacological effects, e.g. benzodiazepines as feed intake enhancers and non-steroidal anti-inflammatory drugs (NSAIDs) as pale meat-making agents. Several non-traditional substances are suspected to be used in the field of breeding animals. This is the case for growth hormones (GHs) and all substances acting over this anabolic compound, as for instance, orally GH secretagogue. Moreover, ecdysteroids, which according to old Russian studies, have anabolic activity, are actually very easy to purchase on the Internet. Recent findings in different classes of growth promoters are discussed in detail.

Facile synthesis of tetrahydroprotoberberine and protoberberine alkaloids from protopines and study on their antibacterial activities

A series of isoquinoline alkaloids including tetrahydroprotoberberines, N-methyl tetrahydroprotoberberines and protoberberines were facile synthesised with protopines as the starting material. All compounds were evaluated for their antibacterial activities against four pathogenic bacteria Escherichia coli, Staphyloccocus aureus, Staphylococcus gallinarum and Salmonella choleraesuis. Experimental results indicated that protoberberines were the most active compounds to the target bacteria among the tested alkaloids. It was suggested that planar molecule with high aromatisation level (e.g. coptisine 5 and berberine 6) or a positive charge of the molecules (e.g. N-methyl tetrahydroprotoberberines 11 and 12) had a positive influence on the antibacterial effects.
