Abstract
Uronium peptide coupling agents (HBTU, HATU, and HCTU) create a special hazard as they are immune sensitizers. Few reported cases are mentioned in the literature; despite that, it is important to raise the awareness on the subject and to highlight the risk and potential symptoms that could occur to those who directly work in contact with uronium peptide coupling agents, as well as to the safety deputies in the universities and industries. Based on a personal experience, the health impact of laboratory exposure to HBTU is described, and the insights gained from the experience are developed. A skin irritation reaction and allergy symptoms induced by HBTU exposure are shown here as well as the rate of worsening of symptoms since the first allergic reaction. Recommendations for handling coupling agents more safely in the research laboratory will also be given, and a casuistry of the matter to help other lab-users to recognize, assess, minimize, prepare for emergencies (RAMP) process.
期刊介绍：
The official Journal of the European Peptide Society EPS
The Journal of Peptide Science is a cooperative venture of John Wiley & Sons, Ltd and the European Peptide Society, undertaken for the advancement of international peptide science by the publication of original research results and reviews. The Journal of Peptide Science publishes three types of articles: Research Articles, Rapid Communications and Reviews.
The scope of the Journal embraces the whole range of peptide chemistry and biology: the isolation, characterisation, synthesis properties (chemical, physical, conformational, pharmacological, endocrine and immunological) and applications of natural peptides; studies of their analogues, including peptidomimetics; peptide antibiotics and other peptide-derived complex natural products; peptide and peptide-related drug design and development; peptide materials and nanomaterials science; combinatorial peptide research; the chemical synthesis of proteins; and methodological advances in all these areas. The spectrum of interests is well illustrated by the published proceedings of the regular international Symposia of the European, American, Japanese, Australian, Chinese and Indian Peptide Societies.
