β-Guanidinopropionic acid, also known as Ompenaclid (RGX-202), is being investigated in colorectal cancer by Inspirna and Merck^[2]

β-Guanidinopropionic acid is a white crystalline powder soluble in water (50 mg/ml-clear, colorless solution).^[3]

Studies on animals (rats, monkeys, hamsters) show that acidic guanidine derivatives such as β-GPA can ameliorate hyperglycemia in animal models of noninsulin-dependent diabetes.^[4]

Though the oral availability of β-GPA is well established, the basic uptake mechanism has not been studied yet.^[5]
