about the Event

The use of enzymes is a key component in making manufacturing routes of active pharmaceutical ingredients (APIs) more sustainable and environmentally friendly. Learn in this webinar how enzymes – used for chemo-enzymatic peptide synthesis produced by EnzyTag – enable greener peptide syntheses and what questions appear around the use of enzymes in a GMP setting: Which control strategies and regulatory considerations have to be taken into account? Which risk assessments are in place?

Bernd Raschack studied chemistry and received his diploma at the Albert-Ludwigs University in Freiburg, Germany. He earned his doctorate from the same University in close cooperation with pharmaceutical company Knoll AG (now Abbvie) in Ludwigshafen, Germany. His dissertation was about studying the influence of the Growth Arrest Homeobox Gene (GAX) on the process of restenosis and its suitability as a potential gene therapeutic target. Bernd joined Bachem AG in Bubendorf, Switzerland in 2001. He was the first hired staff with the aim to establish a sustainable NCE (New Chemical Entity) customer pipeline for Bachem in Europe. He also earned a diploma from Fachhochschule Nordwestschweiz (FHNW) in 2005 about his work on analyzing and suggestions for improving Key Account and Project Management aspects at Bachem.
