The first-in-class small-molecule gp130 inhibitor with oral activity in ovarian cancer (IC50 values 0.43-0.95 µM for a range of human ovarian cancer cell lines). SC144 binds gp130, induces gp130 phosphorylation and deglycosylation, abrogates Stat3 phosphorylation and nuclear translocation, and further inhibits the expression of downstream target genes.

Glucosamine-induced inhibition of N-glycosylation of gp130 represses the IL6/JAK/STAT3 signaling in DU145 cells. To determine whether the deficiency in N-glycosylation has any effects on the activity of the gp130-associated IL-6/JAK/STAT3 signaling [], we carried out the following investigations.First, we studied IL-6 binding to DU145 cells in the presence and absence of glucosamine.

Share this grant: : Although inhibition of STAT3 phosphorylation roughly paralleled the time course of gp130 disappearance, inhibition of gp130 disappearance by caspase inhibitors did not restore IL‐6–mediated STAT3 activation in the presence of hydrophobic bile acids. 2016-08-18 2017-07-03 2021-03-20 Leukemia inhibitor factor (LIF) and gp130 in early defence against HIV-1 infection. Author: Tjernlund, Annelie.

However, Raf/MEK/ERK signaling, which also is downstream of GP130 is activated by SC144. This 2019-02-08 · Bazedoxifene, a third- generation selective estrogen modulator approved by the Food and Drug Administration (FDA), is a novel inhibitor of IL-11/GP130 signaling discovered by docking modeling. In this study, we show that gp130 is an attractive drug target in ovarian cancer due to its role in promoting cancer progression via the activation of its downstream Stat3 signaling. We also present preclinical studies of SC144, the first-in-class orally active small-molecule gp130 inhibitor. For the stimulant drug, see G-130. Glycoprotein 130 (also known as gp130, IL6ST, IL6-beta or CD130) is a transmembrane protein which is the founding member of the class of all cytokine receptors. It forms one subunit of the type I cytokine receptor within the IL-6 receptor family.

The binding of IL-6 to IL-6Rα induces trimer formation via gp130 is a common element of receptors that belong to the interleukin-6 (IL-6) receptor Protein inhibitor of activated STAT3 (PIAS3) interacts directly with gp130 is the common receptor β subunit shared by IL-6, ciliary neurotrophic factor (CNTF), oncostatin M, IL-11, cardiotrophin 1, and leukemia inhibitory factor Jun 30, 2020 Inhibition of either Src or Yap could cause the suspense of gp130-induced heart regeneration in Myh6-gp130ACT mice after MI injury. Yap entry Aug 18, 2016 The possible modulation of gp130/STAT3 signaling by SPRC in Dox-induced cell death was next evaluated. Leukemia inhibitory factor (LIF), an Feb 8, 2019 The FDA-approved drug bazedoxifene, known as a selective estrogen modulator, is currently used for the postmenopausal osteoporosis [23]. Inhibitor of gp130 (IC50 = 0.72 μM); blocks cytokine-triggered gp130 signaling.

From a rheumatologist's perspective, IL-6 is the most important cytokine in this subfamily. small-molecule gp130 inhibitor with oral activity in ovar-ian cancer. Materials and Methods Reagents SC144, a quinoxalinhydrazide derivative, was synthe-sized as described (9).

2017-07-03 · Interleukins-6 (IL-6)/GP130 signaling pathway represents a promising target for cancer therapy due to its critical role in survival and progression of multiple types of cancer. We have identified Bazedoxifene, a Food and Drug Administration (FDA)-approved drug used for the prevention of postmenopausal osteoporosis, with novel function as inhibitor of IL-6/GP130 interaction.

Our previous work has repositioned this drug as a potent GP130 in-hibitor in pancreatic cancer therapy [25], but its effects on colon cancer have not been investigated. Although IL-6 has been associated with many epithelial cancers, IL-11 acts as a more potent driver of colorectal cancers [22]. We correlate post-treatment induction of this pathway in anti-TNF non-responders and demonstrate in vivo amelioration of the activated myeloid-stromal niche, using a specific gp130 inhibitor 2008-09-23 Leukemia inhibitor factor (LIF) is a polyfunctional cytokine that belongs to the IL-6 family which mainly signals through the Jak/Stat pathway via the gp130/LIFR-α heterodimer. The focus of my research has been to investigate and understand if and how LIF exerts HIV-1 suppressing activity. 2009-04-30 SC144 is an inhibitor of gp130 with IC50 values of 0.43 μmol/L and 0.88 μmol/L in NCI/ADR-RES and HEY cell lines, respectively [1].
