Welcome to the panabc.info database, which is part of the PANABC Project. The panabc.info database provides broad-scale information on multitarget ABC transporter modulators and gives a detailed collection of chemical and structural information, modulatory activities, transporter host systems, functional tracers, experimental assays, and associated original literature.

The PANABC Project was founded by Dr. Vigneshwaran Namasivayam and Dr. Sven Marcel Stefan. It was initiated in 2018 and is currently funded by the German Research Foundation (Germ. ‘Deutsche Forschungsgemeinschaft‘, DFG; grant no. #504079349; 2022-2025). Related funding: DFG #466106904 (2021–2023); DFG #446812474 (2020–2023).

The PANABC Network is supported by Prof. Dr. Zhe-Sheng Chen, Department of Pharmaceutical Sciences, College of Pharmacy and Health Sciences, St. John’s University, Queens, New York, United States; Prof. Dr. Thomas Efferth, Department of Pharmaceutical Biology, Johannes-Gutenberg-University of Mainz, Mainz, Germany; Prof. Dr. Marco Falasca, Metabolic Signalling Group, Curtin Health Innovation Research Institute, Curtin University Perth, Perth, Australia; Dr. Patric Jansson, Cancer Drug Resistance and Stem Cell Program, Kolling Institute, The University of Sydney, New South Wales, Australia; Dr. Till Luckenbach, Helmholtz Centre for Environmental Research, Leipzig, Germany, Leipzig, Germany; Dr. Csilla Özvegy-Laczka, Institute of Enzymology, ELKH Research Centre for Natural Sciences, Budapest, Hungary; Prof. Dr. Dr. Jens Pahnke, Translational Neurodegeneration Research and Neuropathology Lab, Department of Pathology, University of Oslo, Oslo, Norway; Dr. Erik Sveberg Dietrichs, Experimental and Clinical Pharmacology, Faculty of Health Sciences, The Arctic University of Norway, Tromsø, Norway; and Prof. Dr. Maojun Yang, School of Life Sciences, Tsinghua University, Beijing, China. 

The scope of the project is the direct targeting of all human ABC transporters through a polypharmacological approach for the discovery of novel and potent ABC transporter-targeting diagnostics and therapeutics and to explore particularly under-studied ABC transporters as potential pharmacological targets of the future.
