Small molecule therapeutic for Steroid Resistant Nephrotic Syndrome (SRNS)
A compound for the potential treatment of SRNS. Developed by Professor Moin Saleem and colleagues at the University of Bristol in Bristol Renal.
Problem:
Steroid-resistant nephrotic syndrome (SRNS) is a devastating disease affecting both adults and children resulting from the breakdown of the kidney filtration barrier. It usually leads to end-stage renal disease (ESRD) despite the use of prolonged and toxic immunosuppression, with associated lifelong costs of dialysis and transplantation.
Solution:
Podocin is a key component of the glomerular filtration barrier and mutations in the podocin encoding gene NPHS2 lead to SRNS. These mutations or changes in genetic code represent the commonest form of inherited Nephrotic Syndrome (NS), up to 20% of all single-gene cases. The most frequent mutation is R138Q, causing mistrafficking of Podocin. We have tested a number of tool compounds that rescue this mistrafficking and restore normal function in our gold standard cell lines and a relevant and translatable mouse model.
Available Packages:
Bristol is seeking to establish partnerships with drug development companies in order to progress this therapeutic approach towards the clinic.
