Andreas Grill, President and CEO of DepYmed, discusses protein tyrosine phosphatase-targeted drugs, a new class of drugs. With a focus on the specific enzyme PTP1B, DepYmed discovered orally bioavailable molecules that inhibit PTP1B, targeting the signal transaction pathway. They are initially testing to treat Rett syndrome, a rare disease with no current therapy while exploring the use of PTP1B inhibitors to treat inflammatory diseases, cancer, diabetes, and neurological diseases.   Andreas elaborates, "In DepYmed, we're focused on a specific enzyme. It's PTP1B. It's part of a family of enzymes called protein tyrosine phosphatases, and, in particular, we're looking at PTP1B. It's a metabolic regulatory enzyme that regulates signal transduction between cells and how cells communicate with each other. It's been worked on in the '90s and early 2000s. A couple of companies were working on the target, and they failed in the target, mainly because they couldn't create an orally bioavailable compound that would inh
