About

The kidneys have important functions within organisms such as detoxification, regulation of extracellular fluids, homeostasis and excretion of toxic metabolites [1]. Impairment of normal kidney function can lead to severe diseases and, if untreated, to death. Such impairment can be caused by substances that interact with molecular mechanisms leading to nephrotoxicity, including renal tubular toxicity, inflammation, glomerular damage, crystal nephropathy and thrombic microangiopathy [1]. One typical mechanism is that the drug induces inflammatory responses and oxidative stress that lead to necrosis and apoptosis which results in tissue damage, reduced Glomerular Filtration Rates and acute kidney injury. (Figure 1).

Therefore, especially during drug development and in the food industry, where exposure of substances to the kidney is high, assessment for nephrotoxic risk of compounds is key to ensure the development of safe and sustainable products which customers can use without any concern. At SaferWorldbyDesign we provide solutions with which you can characterize your compounds and based on this make important decisions throughout the development of your products to ensure that your products are safe and sustainable.

Our services

With our Nephrotoxicity package we provide a wide variety of solutions adapted to your needs. With our machine learning in silico approaches we characterize your compounds in a in concern of nephrotoxicity to offer you results with which you can make important decisions during product development.

Our services are based on a tiered strategy where we provide in silico machine learning solutions in a first phase. Thereby, we apply a variety of algorithms on already existing data from verified datasets. Based on feature extraction and ontology characterization, we evaluate your compounds and provide you with a detailed report as base to discuss on how you can proceed to improve your products, ensuring consumer safety and sustainability.

In a second tier approach we further evaluate your compounds by next generation in vitro assays that are specific for endocrine disruption endpoints. Resulting data can be implemented into the in silico tools to confirm outcomes of the first tier.

Data management is key for successful and efficient risk assessment. At SaferWorldbyDesign, we manage data under FAIR principles so that it is easy Findable, Accessible, Interoperable and Reusable. Thereby, our data is harmonized and managed through premium customer accounts on a secure cloud.
