2. Novel clean-up, concentration and laser desorption/ionization strategies for mass spectrometry
Abstract : Despite valuable advantages of mass spectrometry (MS) techniques they still have drawbacks that need to be overcome, notably their sensitivity to various kinds of interfering substances and associated difficulties involved in detecting signals from analytes present in trace quantities. Thus, high quality analytical data could be acquired by improving sample pre-treatment techniques and/or ionization methods to increase ionization yields and/or avoid the generation of unwanted ions.

3. Synthesis Towards Biologically Active Natural Products
Abstract : In 2005 two research groups independently reported the isolation of a series of structurally intriguing C-19 terpenolides from the plants Thapsia transtagana and Thapsia garganica. The compounds were shown to be potent inhibitors of the sarco/endoplasmic reticulum Ca2+-ATPases. READ MORE
