[https://www.uniprot.org/uniprot/AGAL_HUMAN AGAL_HUMAN] Defects in GLA are the cause of Fabry disease (FD) [MIM:[https://omim.org/entry/301500 301500]. FD is a rare X-linked sphingolipidosis disease where glycolipid accumulates in many tissues. The disease consists of an inborn error of glycosphingolipid catabolism. FD patients show systemic accumulation of globotriaoslyceramide (Gb3) and related glycosphingolipids in the plasma and cellular lysosomes throughout the body. Clinical recognition in males results from characteristic skin lesions (angiokeratomas) over the lower trunk. Patients may show ocular deposits, febrile episodes, and burning pain in the extremities. Death results from renal failure, cardiac or cerebral complications of hypertension or other vascular disease. Heterozygous females may exhibit the disorder in an attenuated form, they are more likely to show corneal opacities.<ref>PMID:2152885</ref> <ref>PMID:1846223</ref> <ref>PMID:2171331</ref> <ref>PMID:2539398</ref> <ref>PMID:1315715</ref> <ref>PMID:7504405</ref> <ref>PMID:8395937</ref> <ref>PMID:8069316</ref> <ref>PMID:7531540</ref> <ref>PMID:7575533</ref> <ref>PMID:7759078</ref> <ref>PMID:7599642</ref> <ref>PMID:7596372</ref> <ref>PMID:8738659</ref> <ref>PMID:8875188</ref> <ref>PMID:8834244</ref> <ref>PMID:8931708</ref> <ref>PMID:8807334</ref> <ref>PMID:8863162</ref> <ref>PMID:9105656</ref> <ref>PMID:9100224</ref> <ref>PMID:9554750</ref> <ref>PMID:9452068</ref> <ref>PMID:9452090</ref> <ref>PMID:9452111</ref> <ref>PMID:10208848</ref> <ref>PMID:10090526</ref> <ref>PMID:10838196</ref> <ref>PMID:10666480</ref> <ref>PMID:11076046</ref> <ref>PMID:10916280</ref> <ref>PMID:11295840</ref> <ref>PMID:11668641</ref> <ref>PMID:11889412</ref> <ref>PMID:12694230</ref> <ref>PMID:12786754</ref> <ref>PMID:15162124</ref> <ref>PMID:15712228</ref> <ref>PMID:16533976</ref> <ref>PMID:19621417</ref>

Fabry disease (FD) is an X-linked lysosomal storage disorder caused by mutations in the GLA gene often leading to missense alpha-galactosidase A (alpha-Gal A) variants that undergo premature endoplasmic reticulum-associated degradation due to folding defects. We have synthesized and characterized a new family of neutral amphiphilic pharmacological chaperones, namely 1-deoxygalactonojirimycin-arylthioureas (DGJ-ArTs), capable of stabilizing alpha-Gal A and restoring trafficking. Binding to the enzyme is reinforced by a strong hydrogen bond involving the aryl-N'H thiourea proton and the catalytic aspartic acid acid D231 of alpha-Gal A, as confirmed by a 2.55 A resolution cocrystal structure. Selected candidates enhanced alpha-Gal A activity and ameliorate globotriaosylceramide (Gb3) accumulation and autophagy impairments in FD cell cultures. Moreover, they acted synergistically with the proteostasis regulator 4-phenylbutyric acid, appearing to be promising leads as pharmacological chaperones for FD.
