Tohoku Univ. Technology：Lubiprostone, a constipation drug, has a kidney protective effect：T25-005
Improvement of Intestinal Microbiota Improves Mitochondrial Function
Chronic kidney disease (CKD) is a major global health issue without any drugs that improve kidney function. Previous mouse experiments showed that lubiprostone, a constipation drug, reduces uremic toxin accumulation by improving the intestinal environment altered by kidney decline, thus inhibiting kidney damage progression 1. A phase II clinical trial was conducted to test lubiprostone's effects on kidney function in patients. Results revealed dose-dependent suppression of kidney function decline (eGFR) in lubiprostone-treated patients compared to placebo. Further analysis showed lubiprostone improves kidney mitochondrial function by modulating the gut microbiota and increasing spermidine production, which enhances mitochondrial activity and provides kidney protection.

Company information
The revenue generated from technology transfer is reinvested as new research funding for universities and researchers, and is utilized to create further research outcomes. To ensure the smooth operation of this cycle, known as the "Intellectual Creation Cycle," we will vigorously promote technology transfer. The types of seeds we handle include patents, know-how, databases, and programs. We have established a collaborative framework by signing basic technology transfer agreements with the following universities (as of June 1, 2025): Tohoku University, Hirosaki University, Iwate University, Akita University, Fukushima University, Yamagata University, Tohoku Gakuin University, Iwate Medical University, Fukushima Medical University, Aizu University, Miyagi University, Hokkaido University, Muroran Institute of Technology, and Showa Medical University.
