The pig endometrial arylsulphatase A was purified 3322-fold to a specific activity of 150 mumol/min per mg. The purification involved (NH4)2SO4 fractionation, chromatography on concanavalin A-Sepharose and DEAE-Sepharose, gel filtrations on Sephadex G-200 at pH 7.4 and 5, and a new preparative gel-electrophoresis technique. The homogeneous enzyme is a glycoprotein containing 20% carbohydrate. The purified enzyme has Mr about 120 000 and it contains subunits of Mr 63 000. The pig endometrial arylsulphatase A shows many properties in common with those of arylsulphatases A purified from other sources. The similarities include their low isoelectric points, the anomalous time-activity relationships, multi-pH optima, inhibition by SO3(2-), SO4(2-), phosphate ions, metal ions and nucleoside phosphates, pH- and ionic-strength-dependent polymerization and amino acid composition. ...

The relative activities of arylsulphatases A and B were measured in rat liver parenchymal and non-parenchymal cells, in peritoneal macrophages and in a number of rat tissues. Although absolute values cannot be obtained, it was shown that the arylsulphatase B/arylsulphatase A activity ratio is much higher in non-parenchymal cells than in parenchymal cells. The ratios in adrenals, brain and testis are very similar to each other but differ from those found in spleen, kidney and liver. These ratio variations may be caused by alterations in the activity of the B enzyme rather than the A enzyme. The relatively high B enzyme/A enzyme ratios in all rat tissues explains why the method devised for the independent assay of human arylsulphatases A and B cannot be employed with rat tissues.. ...

The development of potent steroid sulfatase inhibitors is an important new therapeutic strategy for the treatment of postmenopausal women with breast cancer. A series of tricyclic coumarin sulfamates were synthesized, and their inhibitory properties were examined in vitro and in vivo. In a placental microsomal assay system, 667 COUMATE emerged as the most potent inhibitor with an IC50 of 8 nM. Administration of a single dose (10 mg/kg, p.o.) of 667 COUMATE inhibited rat liver estrone sulfatase activity by 93%. 667 COUMATE was devoid of estrogenicity, as indicated by its failure to stimulate the growth of uteri in ovariectomized rats. In vivo, estrone sulfate-stimulated growth of uteri in ovariectomized rats was inhibited by 667 COUMATE. Using the nitrosomethylurea-induced mammary tumor model, we found that 667 COUMATE caused regression of estrone sulfate-stimulated tumor growth in a dose-dependent manner. The identification of 667 COUMATE as a potent steroid sulfatase inhibitor will enable the
Arylsulfatase A (or cerebroside-sulfatase) is an enzyme that breaks down sulfatides, namely cerebroside 3-sulfate into cerebroside and sulfate. In humans, arylsulfatase A is encoded by the ARSA gene. A deficiency is associated with metachromatic leukodystrophy, an autosomal recessive disease. Arylsulfatase A is inhibited by phosphate, which forms a covalent bond with the active site 3-oxoalanine.

A series of novel D-ring modified derivatives of estrone was synthesized and tested as inhibitors of steroid sulfatase (STS). The steroidal D-ring was cleaved via an iodoform reaction and thermal condensation of the resulting marrianolic acid derivative gave 16,17-seco-estra-1,3,5(10)-triene-16,17-imide derivatives, where a piperidinedione moiety is in place of the D-ring. This synthetic approach was found to give a higher overall yield than the literature method of Beckmann rearrangement. A range of alkyl side chains have been introduced on the nitrogen atom of the imido-ring and the corresponding 3-O-sulfamates synthesized. The new D-ring modified estrone derivatives bearing a propyl (39) and a 1-pyridin-3-ylmethyl (46) moiety had IC(50) values of 1 nM when tested in placental microsomes for the inhibition of STS. These compounds are therefore up to 18-fold more potent than EMATE, the very first highly potent irreversible steroidal STS inhibitor.
Although arylsulfatase A pseudodeficiency is characterized as a disease, about 1-2% of any population of clinically healthy people have two copies of the ARSA pseudodeficiency allele, identified by rs6151429. This does lead to low levels of arylsulfatase (ARSA).[PMID 1678251 ...

Pseudomonas aeruginosa arylsulfatase (PAS) is a bacterial sulfatase capable ofhydrolyzing a range of sulfate esters. Recently, it has been demonstrated to also show very high proficiency for phosphate ester hydrolysis. Such proficient catalytic promiscuity is significant, as promiscuity has been suggested to play an important role in enzyme evolution. Additionally, a comparative study of the hydrolyses of the p-nitrophenyl phosphate and sulfate monoesters in aqueous solution has demonstrated that despite superficial similarities, the two reactions proceed through markedly different transition states with very different solvation effects, indicating that the requirements for the efficient catalysis of the two reactions by an enzyme will also be very different (and yet they are both catalyzed by thesame active site). This work explores the promiscuous phosphomonoesterase activity ofPAS. Specifically, we have investigated the identity of the most likely base for the initial activation of the ...

On October 6, 2016 results were published in the PLOS journal regarding a recent X-Linked personality survey. The article is titled Behavioural and Psychiatric Phenotypes in Men and Boys with X-Linked Ichthyosis: Evidence from a Worldwide Online Survey. An abstract of the results can be found at: http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0164417. FIRST MSAB member, Dr. Jennifer Hand of the Mayo Clinic adds, This study is interesting but has important limitations to consider. Many of the individuals studied were collected from within patient support groups. This means that the study is likely biased towards individuals who had severe enough health concerns that they or their families sought out help from a support group. That is, this study probably overemphasizes the behavioral problems associated with XLI. A more meaningful result would come from a random sample of individuals found to have the gene deletion that causes X-linked ichthyosis.. ...

Random Tn917 mutagenesis of Bacillus subtilis followed by selection of lipoic acid auxotrophs led to the isolation of the cysH gene. The gene was sequenced and found to encode a phosphoadenylylsulfate sulfotransferase with a molecular mass of 27 kDa. Expression of lacZ fused to the cysH promoter was repressed by cysteine and sulfide and induced by sulfur limitation, indicating that cysH is controlled at the level of transcription. ...
1114 Recent studies have demonstrated the multi-mechanism anti-tumor effects of 2-substituted estradiol bis-sulfamates and highlighted a number of potential advantages that such compounds possess relative to the corresponding estradiols, which include 2-methoxyestradiol (2-MeOE2, Panzem ™) a drug in Phase II clinical trials. 2-Methoxy- (2-MeOE2bisMATE, STX140, 1) and 2-ethyl-estradiol bis-sulfamate (2-EtE2bisMATE, STX243, 2) display potent anti-proliferative and anti-angiogenic activity and also function as inhibitors of steroid sulphatase (STS), a clinical target for the treatment of hormone dependent breast cancer. In order to generate novel agents with anti-proliferative activity against human breast cancer cells we have synthesised a number of 2-substituted estradiol 3-O-sulfamate analogues with oxygenated side chains tethered at C-17 as bio-isosteric replacements of the 17-O-sulfamate group of the bisMATEs. The 17β-(2-hydroxyethyl) compound 3 in which the hydroxyl group can function as ...

ARS-853 is the first direct KRAS inhibitor shown to selectively inhibit KRAS in cells with potency in the range of a drug candidate. Previously reported KRAS inhibitors have either shown insufficient potency for detailed cellular characterization (2, 3, 6), or exhibit dramatic deviations in potency across assays (4). The most potent covalent KRASG12C ligand reported previously (Compound 12) exhibited promising in vitro properties, but its cellular effects were less clear (6). Here, we demonstrate that Compound 12 is not capable of engaging KRASG12C in cells even at a relatively high dose and long incubation (100 μmol/L for 6 hours). However, by improving upon the groundbreaking approach of targeting the Switch II pocket of KRASG12C with covalent ligands, we have successfully identified a covalent inhibitor that demonstrates consistent low micromolar activity from biochemical and cellular engagement to KRASG12C activation, downstream signaling, and cell survival. Further, we have found that ...
