Background on GI 254023X

Description:IC50: 5.3 nM (ADAM10)
A Disintegrin and metalloproteinase domain-containing protein 10, also known as ADAM10 or CDw156 or CD156c is a protein that in humans is encoded by the ADAM10 gene. ADAM10 (EC#: 3.4.24.81) is a sheddase, and has a broad specificity for peptide hydrolysis reactions (http://en.wikipedia.org/wiki/ADAM10). GI 254023X, synthesized by GSK, was reported to inhibit ADAM10 100-fold over ADAM17. GI 254023X could reduce constitutive cleavage of fractilkine from ECV-304 transfectants [1].
In vitro: Previusl study reported that compound GI254023X possessed comparable inhibitory potency for ADAM10 only and blocked TACE with more than 100-fold reduced potency [2].
In vivo: To examine the ability of GI254023X to inhibit Hla-mediated endothelial barrier disruption in vivo, mice treated for a 3-day period with GI254023X via intraperitoneal injection were subjected to a Miles assay following subcutaneous injection of recombinant toxin. Resutls showed that although all experimental animals succumbed to the lethal challenge, GI254023X-treated mice were less ill in appearance and demonstrated prolongation of time to death [3].
Clinical trial: GI254023X is currently in the preclinical development and no clinical trial is ongoing..

Central Neuromodulators for Treating Functional GI Disorders: A Primer.[Pubmed:28349992]

Am J Gastroenterol. 2017 May;112(5):693-702.

Patients with functional GI disorders (FGIDs) are commonplace in the gastroenterologist's practice. A number of these patients may be refractory to peripherally acting agents, yet respond to central neuromodulators. There are benefits and potential adverse effects to using TCAs, SSRIs, SNRIs, atypical antipsychotics, and miscellaneous central neuromodulators in these patients. These agents can benefit mood, pain, diarrhea, constipation, nausea, sleep, and depression. The mechanisms by which they work, the differences between classes and individual agents, and the various adverse effects are outlined. Dosing, augmentation strategies, and treatment scenarios specifically for painful FGIDs, FD with PDS, and chronic nausea and vomiting syndrome are outlined.

Ten-Year Progression-Free and Overall Survival in Patients With Unresectable or Metastatic GI Stromal Tumors: Long-Term Analysis of the European Organisation for Research and Treatment of Cancer, Italian Sarcoma Group, and Australasian Gastrointestinal Trials Group Intergroup Phase III Randomized Trial on Imatinib at Two Dose Levels.[Pubmed:28362562]

J Clin Oncol. 2017 May 20;35(15):1713-1720.

Purpose To report on the long-term results of a randomized trial comparing a standard dose (400 mg/d) versus a higher dose (800 mg/d) of imatinib in patients with metastatic or locally advanced GI stromal tumors (GISTs). Patients and Methods Eligible patients with advanced CD117-positive GIST from 56 institutions in 13 countries were randomly assigned to receive either imatinib 400 mg or 800 mg daily. Patients on the 400-mg arm were allowed to cross over to 800 mg upon progression. Results Between February 2001 and February 2002, 946 patients were accrued. Median age was 60 years (range, 18 to 91 years). Median follow-up time was 10.9 years. Median progression-free survival times were 1.7 and 2.0 years in the 400- and 800-mg arms, respectively (hazard ratio, 0.91; P = .18), and median overall survival time was 3.9 years in both treatment arms. The estimated 10-year progression-free survival rates were 9.5% and 9.2% for the 400- and 800-mg arms, respectively, and the estimated 10-year overall survival rates were 19.4% and 21.5%, respectively. At multivariable analysis, age (< 60 years), performance status (0 v >/= 1), size of the largest lesion (smaller), and KIT mutation (exon 11) were significant prognostic factors for the probability of surviving beyond 10 years. Conclusion This trial was carried out on a worldwide intergroup basis, at the beginning of the learning curve of the use of imatinib, in a large population of patients with advanced GIST. With a long follow-up, 6% of patients are long-term progression free and 13% are survivors. Among clinical prognostic factors, only performance status, KIT mutation, and size of largest lesion predicted long-term outcome, likely pointing to a lower burden of disease. Genomic and/or immune profiling could help understand long-term survivorship. Addressing secondary resistance remains a therapeutic challenge.

Novel fork-tip needles versus standard needles for EUS-guided tissue acquisition from solid masses of the upper GI tract: a matched cohort study.[Pubmed:28355953]

Scand J Gastroenterol. 2017 Jun - Jul;52(6-7):784-787.

BACKGROUND: There are very few available data on the novel SharkCore needles for EUS-FNB. AIM: Comparison of the performance of the SharkCore needles with the standard EUS-FNA needles for the diagnosis of solid upper GI masses. PATIENTS AND METHODS: Single-center, retrospective cohort study in an academic tertiary referral hospital. Patients were matched 1:1 for the site of the lesion and the presence or absence of rapid on-site evaluation (ROSE). RESULTS: A total of 102 patients were included. There was no statistically significant difference in the mean number of passes (3.3 +/- 1.3 versus 3.4 +/- 1.5; p = .89). Similar results were observed at the subgroup with ROSE (4.3 +/- 1.3 versus 3.7 +/- 1.5; p = .26). More histological specimens were obtained with the SharkCore needles compared to standard needles (59 versus 5%; p < .001). Diagnostic test characteristics were not significantly different (sensitivity: 91.5 versus 85.7; specificity: 100 versus 100%; accuracy: 92.2 versus 85.4% for SharkCore versus standard needles, p > .05 in all cases). At multivariable analysis, there was no statistically significant difference in the mean number of passes in all patients (p = .23) and in the ROSE subgroup (p = .66). However, the SharkCore needle obtained significantly more histological material than the standard needle (odds ratio 66; 95% confidence interval: 11.8, 375.8, p < .001). There was no significant difference in complication rates (p = .5). LIMITATIONS: Retrospective study, single-center. CONCLUSION: The SharkCore needles were similar to standard FNA needles in terms of the number of passes to reach diagnosis, but obtained significantly more histological specimen.

A randomized comparative trial of OTSC and Padlock for upper GI hemostasis in a standardized experimental setting.[Pubmed:28350273]

Minim Invasive Ther Allied Technol. 2017 Apr;26(2):65-70.

INTRODUCTION: Upper gastrointestinal bleeding (UGIB) is the key emergency situation in clinical endoscopy and is traditionally treated with injection, thermal or through the scope clipping therapy. Mortality rates are in the range of 8-10% and demand new treatment approaches. The Over-The-Scope Clip (OTSC((R))) has been described as a very effective hemostatic device in UGIB. We compared OTSC with the Padlock device in an established pre-clinical setting. MATERIAL AND METHODS: Our test-bed consisted of the biohybrid EASIE model using soft silicone tubes, tunneled into the gastric wall and surfacing at a mucosa defect, representing the bleeding site. After successful deployment of the OTSC and Padlock devices on the spurting ulcer bleed (Forrest Ia) the vessel tubes were pressurized with a manometer to 120 mmHg. Tight closure at this pressure was defined as successful hemostasis (primary endpoint). N = 11 procedures were done with each device. Statistical testing was done using Fisher's exact test. Sample size was adjusted to an assumed alpha-error of 5% (two-sided test) and a power of 80%. RESULTS: Technically correct placement of the respective hemostatic device was achieved in all procedures. A statistically significant difference was found in the primary endpoint. In OTSC the success proportion was 100%; 11/11 (95% KI 74.1% to 100%); in Padlock it was 0%; 0/11 (95% KI 0%-25.8%). This means that no bleeding was stopped by Padlock. The mean value of perfusion pressure resistance was 300 mmHg (cut-off) for OTSC and 9.2 +/- 8.4 mmHg for Padlock. DISCUSSION: Our data on hemostatic function of OTSC coincide with the clinical literature and earlier pre-clinical studies in the EASIE model, which is widely accepted as a realistic and effective simulation system for clinical conditions. The inability of Padlock to stop hemorrhage may be due to design differences and, thus, its limitation in providing tight sealing of the clipped tissue. CONCLUSION: Different types of endoscope-tip mounted clips have different performances. OTSC consistently stops simulated spurting bleeding, Padlock fails to do so. These differences are statistically significant.

A Staphylococcus aureus pore-forming toxin subverts the activity of ADAM10 to cause lethal infection in mice.[Pubmed:21926978]

Nat Med. 2011 Sep 18;17(10):1310-4.

Staphylococcus aureus is a major cause of human disease, responsible for half a million infections and approximately 20,000 deaths per year in the United States alone. This pathogen secretes alpha-hemolysin, a pore-forming cytotoxin that contributes to the pathogenesis of pneumonia. alpha-hemolysin injures epithelial cells in vitro by interacting with its receptor, the zinc-dependent metalloprotease ADAM10 (ref. 6). We show here that mice harboring a conditional disruption of the Adam10 gene in lung epithelium are resistant to lethal pneumonia. Investigation of the molecular mechanism of toxin-receptor function revealed that alpha-hemolysin upregulates ADAM10 metalloprotease activity in alveolar epithelial cells, resulting in cleavage of the adherens junction protein E-cadherin. Cleavage is associated with disruption of epithelial barrier function, contributing to the pathogenesis of lethal acute lung injury. A metalloprotease inhibitor of ADAM10 prevents E-cadherin cleavage in response to Hla; similarly, toxin-dependent E-cadherin proteolysis and barrier disruption is attenuated in ADAM10-knockout mice. Together, these data attest to the function of ADAM10 as the cellular receptor for alpha-hemolysin. The observation that alpha-hemolysin can usurp the metalloprotease activity of its receptor reveals a previously unknown mechanism of pore-forming cytotoxin action in which pathologic insults are not solely the result of irreversible membrane injury and defines ADAM10 inhibition as a strategy to attenuate alpha-hemolysin-induced disease.

The ADAM10 prodomain is a specific inhibitor of ADAM10 proteolytic activity and inhibits cellular shedding events.[Pubmed:17895248]

J Biol Chem. 2007 Dec 7;282(49):35712-21.

ADAM10 is a disintegrin metalloproteinase that processes amyloid precursor protein and ErbB ligands and is involved in the shedding of many type I and type II single membrane-spanning proteins. Like tumor necrosis factor-alpha-converting enzyme (TACE or ADAM17), ADAM10 is expressed as a zymogen, and removal of the prodomain results in its activation. Here we report that the recombinant mouse ADAM10 prodomain, purified from Escherichia coli, is a potent competitive inhibitor of the human ADAM10 catalytic/disintegrin domain, with a K(i) of 48 nM. Moreover, the mouse ADAM10 prodomain is a selective inhibitor as it only weakly inhibits other ADAM family proteinases in the micromolar range and does not inhibit members of the matrix metalloproteinase family under similar conditions. Mouse prodomains of TACE and ADAM8 do not inhibit their respective enzymes, indicating that ADAM10 inhibition by its prodomain is unique. In cell-based assays we show that the ADAM10 prodomain inhibits betacellulin shedding, demonstrating that it could be of potential use as a therapeutic agent to treat cancer.

Metalloproteinase inhibitors for the disintegrin-like metalloproteinases ADAM10 and ADAM17 that differentially block constitutive and phorbol ester-inducible shedding of cell surface molecules.[Pubmed:15777180]

Comb Chem High Throughput Screen. 2005 Mar;8(2):161-71.

The transmembrane metzinkin-proteases of the ADAM (a disintegrin and a metalloproteinase)-family ADAM10 and ADAM 17 are both implicated in the ectodomain shedding of various cell surface molecules including the IL6-receptor and the transmembrane chemokines CX3CL1 and CXCL16. These molecules are constitutively released from cultured cells, a process that can be rapidly enhanced by cell stimulation with phorbol esters such as PMA. Recent research supports the view that the constitutive cleavage predominantly involves ADAM10 while the inducible one is mediated to a large extent by ADAM17. We here describe the discovery of hydroxamate compounds with different potency against ADAM10 and ADAM17 and different ability to block constitutive and inducible cleavage of IL6R, CX3CL1 and CXCL16 by the two proteases. By screening a number of hydroxamate inhibitors for the inhibition of recombinant metalloproteinases, a compound was found inhibiting ADAM10 with more than 100-fold higher potency than ADAM17, which may be explained by an improved fit of the compound to the S1' specificity pocket of ADAM10 as compared to that of ADAM17. In cell-based cleavage experiments this compound (GI254023X) potently blocked the constitutive release of IL6R, CX3CL1 and CXCL16, which was in line with the reported involvement of ADAM10 but not ADAM17 in this process. By contrast, the compound did not affect the PMA-induced shedding, which was only blocked by GW280264X, a potent inhibitor of ADAM17. As expected, GI254023X did not further decrease the residual release of CX3CL1 and CXCL16 in ADAM10-deficient cells verifying that the compound's effect on the constitutive shedding of these molecules was exclusively due to the inhibition of ADAM10. Thus, GI254023X may by of use as a preferential inhibitor of constitutive shedding events without effecting the inducible shedding in response to agonists acting similar to PMA.

The disintegrin-like metalloproteinase ADAM10 is involved in constitutive cleavage of CX3CL1 (fractalkine) and regulates CX3CL1-mediated cell-cell adhesion.[Pubmed:12714508]

Blood. 2003 Aug 15;102(4):1186-95.

The CX3C chemokine fractalkine (CX3CL1) exists as a membrane-expressed protein promoting cell-cell adhesion and as a soluble molecule inducing chemotaxis. Transmembrane CX3CL1 is converted into its soluble form by defined proteolytic cleavage (shedding), which can be enhanced by stimulation with phorbol-12-myristate-13-acetate (PMA). PMA-induced CX3CL1 shedding has been shown to involve the tumor necrosis factor-alpha-converting enzyme (TACE), whereas the constitutive cleavage in unstimulated cells remains elusive. Here we demonstrate a role of the closely related disintegrin-like metalloproteinase 10 (ADAM10) in the constitutive CX3CL1 cleavage. The hydroxamate GW280264X, capable of blocking TACE as well as ADAM10, proved to be an effective inhibitor of the constitutive and the PMA-inducible CX3CL1 cleavage in CX3CL1-expressing ECV-304 cells (CX3CL1-ECV-304), whereas GI254023X, preferentially blocking ADAM10 but not TACE, reduced the constitutive cleavage only. Overexpression of ADAM10 in COS-7 cells enhanced constitutive cleavage of CX3CL1 and, more importantly, in murine fibroblasts deficient of ADAM10 constitutive CX3CL1 cleavage was markedly reduced. Thus, ADAM10 contributes to the constitutive shedding of CX3CL1 in unstimulated cells. Addressing the functional role of CX3CL1 shedding for the adhesion of monocytic cells via membrane-expressed CX3CL1, we found that THP-1 cells adhere to CX3CL1-ECV-304 cells but detach in the course of vigorous washing. Inhibition of ADAM10-mediated CX3CL1 shedding not only increased adhesive properties of CX3CL1-ECV-304 cells but also prevented de-adhesion of bound THP-1 cells. Our data demonstrate that ADAM10 is involved in the constitutive cleavage of CX3CL1 and thereby may regulate the recruitment of monocytic cells to CX3CL1-expressing cell layers.
