ProQinase will identify novel biomarkers for anti-tumour therapies as member of the EU-research consortium „ANGIOTARGETING - European Consortium for Tumour Angiogenesis Research”

Reliable prediction about the success or failure of new anti-tumor therapies can be provided by so-called biomarkers. Biomarkers are patient characteristics, e.g. presence of specific proteins, of which the amount changes as a result of a therapeutic intervention. Detection of biomarkers in peripheral blood of tumor patients can represent a simple and non-invasive method to determine the success or failure of a given treatment. As part of an EU-funded research program ProQinase, a business division of KTB Tumorforschungsgesellschaft mbH at the Tumorbiology Center Freiburg, will identify novel potential biomarkers.


In January 2007 ProQinase became a partner of the „European Consortium for Tumour Angiogenesis Research“, an integrated project that is funded by the EU with 6 Mio Euro. Aim of the research program is the investigation of mechanisms that control the formation of novel blood vessels in tumors (tumor angiogenesis) and the development of novel therapeutical approaches. Fourteen laboratories from ten countries are participating in the project that is coordinated by the University of Bergen, Norway (


ProQinase uses its Integrated Technology platform to develop kinase inhibitors and to identify, to develop, and carry-out biomarker assays ( The company is today one of the biggest service providers of preclinical technologies in the field of protein kinases. As part of the EU-research project, these resources will be used under the supervision of Dr. Michael Kubbutat (Head Research & Development, ProQinase) for the identification of novel potential biomarkers.


„Identification and development of biomarkers are pivotal for the verification and application of novel therapies in oncology. Biomarkers will allow verification of the mechanism of action and the efficacy of drugs and can help to select the best therapy for the individual patient“, states Kubbutat. „ProQinase offers already several Biomarker-assays for clinical studies, however, for most novel therapies suitable biomarkers are heavily missed. With the help of the EU funding, ProQinase can increase significantly its effort to identify novel biomarkers in cooperation with research groups from academia and industry“.

Reaction Biology Corporation Awarded Phase II SBIR Grant for Drug Discovery

Reaction Biology Corp. today announced that it has been awarded a Phase II SBIR grant from the National Institutes of Health to apply its new DiscoveryDot™ High Throughput Screening technology for drug discovery.

The $750,000 grant originates from the National Institute of Dental and Craniofacial Research and funds the use of RBC’s DiscoveryDot™ microarray technology for high throughput screening of caspases and other proteases. The DiscoveryDot™ technology is capable of screening up to 6,600 individual reactions on a 1-by-3 inch glass slide. The one nanoliter reaction volume used by RBC represents one ten-thousandth the volume of conventional screening systems, and can potentially save millions of dollars on large scale screening campaigns through reagent savings, process costs, and labor reduction.

Caspases play pivotal roles in regulating cell apoptosis and represent targets of significant interest in craniofacial medicine and other areas. RBC’s ability to print large chemical compound libraries in hundreds of replicate copies for caspase and protease screening can accelerate early-stage lead identification at a fraction of the cost of conventional technology.

ProQinase and the University of Duesseldorf receive BMBF-Grant for German-Chinese Research Project for the discovery of novel drugs for the treatment of cancer and viral diseases

ProQinase GmbH at the Tumor Biology Center Freiburg, Germany, and the Institute of Pharmaceutical Biology and Biotechnology at the University of Duesseldorf, Germany, announced the start of a research project for the discovery of novel anti-cancer drugs. In cooperation with the Universities of Beijing and Qingdao, China, the Chinese Academy of Sciences and the Chinese biotech company Pason-Biotech, scientists will isolate natural compounds from Chinese marine organisms, and investigate their usefulness for the treatment of cancer and viral diseases. China offers an immense variety of marine organisms that represent a largely unexplored source for natural compounds with medical potential. The project combines the expertise of the Chinese scientists in the field of marine organisms and natural compound chemistry, the knowledge of the groups of Prof. Peter Proksch and Dr. Rainer Ebel of the University of Duesseldorf in the area of natural compound purification and characterization with the know-how of the biotech companies in the field of drug development for viral infections (Pason Biotech) and cancer (ProQinase). The project will be supported by the German Federal Ministry of Research as part of its “Biotechnology Research and Technology-Programme” with about 1 Mio. Euro in the next three years.


Marine organisms such as sponges, snails, algae, fungi and bacteria represent an approved source for compounds with a medical use for different diseases such as cancer (Ara-C), pain (Conotoxin), and viral diseases (Ara-A). Natural compounds are also used as a starting point for the generation of synthetic drugs such as AZT for the treatment of AIDS. „So far more than 10,000 natural compounds with pharmacological properties have been discovered. However, just a small number of marine organisms have been explored so far, which means that an invaluable potential for novel drugs exists in this area“, Prof. Proksch explains. „The cooperation with our Chinese partners allows us to investigate marine organisms derived from a region that features a huge diversity of unexplored species“. Compounds isolated from these organisms will be characterized in biological test systems with regard to their anti-viral properties by PASON Biotech. At the same time, the compounds will be analyzed by ProQinase for inhibitory properties against protein kinases and, subsequently, in cellular and in in vivo models with respect to their anti-tumoral effects.


Many protein kinases, when deregulated, are linked causally to the formation of human tumors. Inhibitors of protein kinases such as Gleevec and IRESSA are recently approved anti-cancer drugs. „The development of protein kinase inhibitors for the treatment of cancer is just at the very beginning. Due to the diversity of molecular alterations found in human cancers, the lack of efficient and safe drugs for the treatment of the different types of cancer is substantial. In this context the development of protein kinase inhibitors represents a very promising strategy“, states Dr. Michael Kubbutat, Head of Research & Development at ProQinase. „ProQinase works on a novel strategy with the goal to develop drugs that simultaneously block different mechanisms that allow the tumors to grow. Bringing together this novel strategy with the potential of natural compounds of yet unexplored marine organisms could result in the discovery of completely novel drugs“.

ProQinase participates in EU FP6Research Program „Protein Kinases –Novel Drug Targets of Post Genomic Era“

ProQinase GmbH has received a grant from the 6th European Framework Program( The Biotech Company is participating in the “ProKinaseResearch” consortium of 23 partners from eleven countries and is coordinated by the University of Helsinki ( Aim of the research is the development of novel inhibitors of protein kinases. Such substances have applications for the treatment of various diseases such as cancer.


Protein kinases are involved in the regulation of crucial steps in the life cycle of cells, i .e.cell growth, death, and differentiation. Not properly controlled, defective, or hyperactive protein kinases are a common cause for cancer and many other disorders. The sequencing of the human genome has revealed more than 500 genes for protein kinases with often still undefined function, but huge potential for drug development.“Today protein kinase inhibitors are very much in the focus of cancer research, as these substances could arrest or at least slow down the growth of tumors,” explains Dr.Kubbutat, head of the project at ProQinase GmbH. “A very few inhibitors like Gleevec to treat CML (a form of leukemia) are already approved. Still, we are lacking therapeutics for many more kinds of cancer. The EU funding helps substantially to intensify our research on protein kinase inhibitors in collaboration with academic and industrial partners."

4SC and ProQinase collaborate on the discovery of new protein kinase inhibitors for cancer treatment.

4SC AG and ProQinase GmbH announced today a research collaboration to identify a new generation of protein kinase inhibitors as the basis for the development of new anticancer drugs. Protein kinases are key components of the signaling pathways of cells, including those pathways implicated in the development of tumors.


“ProQinase’s expertise in protein kinase research will provide an excellent starting point for the discovery process,” stated Dr. Ulrich Dauer, CEO of 4SC. “Because of these existing validated targets, we believe that this collaboration will quickly advance potential drug candidates through research into clinical trials.”


ProQinase will provide disease-relevant protein kinase targets using its proprietary integrated technology platform, including cell-based assays and in vivo models. 4SC will apply its virtual High Throughput Screening technology, 4SCan® in combination with its medicinal chemistry capabilities. Identified lead candidate drugs will be synthesized and provided to ProQinase for biological screening and pharmacological testing.


“4SC, with its cost and time-saving discovery process, represents an ideal partner to rapidly deliver validated lead drug candidates,’’ said Dr. Christoph Schächtele, Managing Director of ProQinase. “Our close proximity to the Tumor Biology Center in Freiburg will greatly facilitate taking these potential new cancer drugs into clinical trials.”


Under the terms of the agreement, both collaboration partners will equally share the resulting project rights from this collaboration.
