We found two valienamine derivatives, N-octyl-4-epi-\u03b2-valienamine (NOEV) and N-octyl-\u03b2-valienamine (NOV), as promising therapeutic agents for human \u03b2-galactosidase deficiency disorders (mainly G<jats:sub>M1<\/jats:sub>-gangliosidosis) and \u03b2-glucosidase deficiency disorders (Gaucher disease), respectively. We briefly reviewed the historical background of research in carbasugar glycosidase inhibitors. Originally NOEV and NOV had been discovered as competitive inhibitors, and then their paradoxical bioactivities as chaperones were confirmed in cultured fibroblasts from patients with these disorders. Subsequently G<jats:sub>M1<\/jats:sub>-gangliosidosis model mice were developed and useful for experimental studies. Orally administered NOEV entered the brain through the blood-brain barrier, enhanced \u03b2-galactosidase activity, reduced substrate storage, and improved neurological deterioration clinically. Furthermore, we executed computational analysis for prediction of molecular interactions between \u03b2-galactosidase and NOEV. Some preliminary results of computational analysis of molecular interaction mechanism are presented in this article. NOV also showed the chaperone effect toward several \u03b2-glucosidase gene mutations in Gaucher disease. We hope chaperone therapy will become available for some patients with G<jats:sub>M1<\/jats:sub>-gangliosidosis, Gaucher disease, and potentially other lysosomal storage diseases with central nervous system involvement. <\/jats:p>","DOI":"10.4137\/pmc.s2332","type":"journal-article","created":{"date-parts":[[2017,10,26]],"date-time":"2017-10-26T17:50:56Z","timestamp":1509040256000},"source":"Crossref","is-referenced-by-count":38,"title":["Chaperone Therapy for Neuronopathic Lysosomal Diseases: Competitive Inhibitors as Chemical Chaperones for Enhancement of Mutant Enzyme Activities"],"prefix":"10.4137","volume":"3","author":[{"given":"Yoshiyuki","family":"Suzuki","sequence":"first","affiliation":[{"name":"International University of Health and Welfare Graduate School, Kita Kanemaru, Otawara, 324-8501 Japan."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seiichiro","family":"Ogawa","sequence":"additional","affiliation":[{"name":"Department of Biosciences and Informatics, Faculty of Science and Technology, Keio University, Hiyoshi, Kohoku-ku, Yokohama, 223-8522 Japan."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yasubumi","family":"Sakakibara","sequence":"additional","affiliation":[{"name":"Department of Biosciences and Informatics, Faculty of Science and Technology, Keio University, Hiyoshi, Kohoku-ku, Yokohama, 223-8522 Japan."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2009,5,26]]},"reference":[{"key":"bibr1-PMC.S2332","doi-asserted-by":"publisher","DOI":"10.1146\/annurev.ph.28.030166.002251"},{"key":"bibr2-PMC.S2332","doi-asserted-by":"publisher","DOI":"10.1016\/S0016-5085(65)80041-5"},{"key":"bibr3-PMC.S2332","doi-asserted-by":"publisher","DOI":"10.1089\/rej.2006.9.237"},{"key":"bibr4-PMC.S2332","unstructured":"SuzukiY., NanbaE., MatsudaJ., HigakiK., OshimaA. \u03b2-Galactosidase deficiency (\u03b2-galactosidosis): GM1-Gangliosidosis and Morquio B disease.
