On the basis of their affinity and selectivity towards GH1 \u03b2-glucosidases, reducing and nonreducing bicyclic derivatives having a hydroxylation profile of structural complementarity with d-glucose and incorporating an N\u2032-octyl-isourea or -isothiourea segment were selected for further evaluation of their inhibitory\/chaperoning potential against human glucocerebrosidase (GCase). The 1-deoxynojirimycin (DNJ)-related nonreducing conjugates behaved as stronger GCase inhibitors than the reducing counterparts and exhibited potent chaperoning capabilities in Gaucher fibroblasts hosting the neuronopathic G188S\/G183W mutation, the isothiourea derivative being indeed one of the most efficient chaperone candidates reported up to date (70% activity enhancement at 20 pM). At their optimal concentration, the four selected compounds promoted mutant GCase activity enhancements over 3-fold; yet, the inhibitor\/chaperoning balance became unfavorable at much lower concentration for nonreducing as compared to reducing derivatives.<\/jats:p>","DOI":"10.3390\/molecules23040927","type":"journal-article","created":{"date-parts":[[2018,4,18]],"date-time":"2018-04-18T03:51:13Z","timestamp":1524023473000},"page":"927","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":37,"title":["Probing the Inhibitor versus Chaperone Properties of sp2-Iminosugars towards Human \u03b2-Glucocerebrosidase: A Picomolar Chaperone for Gaucher Disease"],"prefix":"10.3390","volume":"23","author":[{"given":"Teresa","family":"Mena-Barrag\u00e1n","sequence":"first","affiliation":[{"name":"Department of Organic Chemistry, Faculty of Chemistry, University of Sevilla, C\/Profesor Garc\u00eda Gonz\u00e1lez 1, 41011 Sevilla, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.
