A small-molecule pharmacological Itpkb inhibitor ameliorated aGVHD lethality and reversed established cGVHD in BO and scleroderma models, respectively associated with reduced lung M2 macrophage accumulation and lower CD4 + IFN-γ + frequency and number, as well as intracellular IL-22 level. Thus, targeting Itpkb may be employed as a novel

1 Furthermore, pharmaceutical inhibition of ITPKB displayed synergistic attenuation of tumor growth with cisplatin, suggesting ITPKB as a promising synthetic lethal target for cancer therapeutic intervention to overcome cisplatin resistance. A small-molecule pharmacological Itpkb inhibitor ameliorated aGVHD lethality and reversed established cGVHD in BO and scleroderma models, respectively associated with reduced lung M2 macrophage accumulation and lower CD4 + IFN-γ + frequency and number, as well as intracellular IL-22 level. Thus, targeting Itpkb may be employed as a novel Using Itpkb conditional knockout mice and LMW Itpkb inhibitors these studies reveal that Itpkb through its product IP4 inhibits the Orai1/Stim1 calcium channel on lymphocytes. Pharmacological The invention provides a novel class of compounds of formula (I), pharmaceutical compositions comprising such compounds and methods of using such compounds to treat or prevent diseases or disorders associated with abnormal or dysregulated B cell activities, particularly diseases or disorders that involve aberrant activation of inositol 1,4,5-trisphosphate 3-kinase B (ITPKb). small-molecule inhibitors BAMB-4 and GNF362 are reported to specifically inhibit ITPK isoforms (23–25).

Itpkb inhibitor

ITPKB protein regulates inositol phosphate metabolism by phosphorylation of second messenger inositol 1,4,5-trisphosphate, which releases calcium from intracellular store in the endoplasmic reticulum by gating the inositol trisphosphate receptor. ITPKB produces Ins (1,3,4,5)P 4, which does not gate the inositol trisphosphate receptor. Targeting ITPKB with shRNA or its small molecule inhibitor resulted in attenuation of NOX4 activity, imbalanced redox status, and sensitized cancer cells to cisplatin treatment in patient-derived xenografts. The IUPHAR/BPS Guide to Pharmacology. IP 3 kinase B - Inositol 1,4,5-trisphosphate 3-kinases.

Although TCR stimulation induced a marked phosphorylation of Itpkb, inhibition of Erk signaling by U0126 not only reduced this phosphorylation but also induced dephosphorylation of Itpkb.

2021-03-30 · Pharmacological inhibition of ITPKB in mice reduced both LPS-induced tissue swelling and the severity of inflammatory arthritis to a similar extent as that induced by the inhibition of NFAT using

The invention provides a novel class of compounds of formula (I), pharmaceutical compositions comprising such compounds and methods of using such compounds to treat or prevent diseases or disorders associated with abnormal or dysregulated B cell activities, particularly diseases or disorders that involve aberrant activation of inositol 1,4,5-trisphosphate 3-kinase B (ITPKb).

It reveals a novel strategy to treat autoimmune disease. GNF362 binds to the ATP-binding pocket of Itpkb. It also potently inhibits Itpka, as well as Itpkc. 2020-10-27 · These data identify Itpkb as an essential mediator of T cell activation and suggest Itpkb inhibition as a novel approach to treat autoimmune disease. Itpkb controls hematopoietic stem cell homeostasis and prevent death from severe anemia in mice. Itpkb controls survival, proliferation and cytokine production in mouse peripheral T cells.

top print hide 112 entries GNF362 is a selective, potent, and orally bioavailable inhibitor of inositol trisphosphate 3' kinase B (Itpkb) with an IC50 of 9 nM. GNF362 also inhibits Itpka and 2020年12月24日 Conversely, ITPKB overexpression reduced PFF-induced α-synuclein aggregation.

Rat antigen-induced arthritis (rAIA) is a well-studied animal model of arthritis, due to its similarities with human Rheumatoid Arthritis (RA), and the involvement of T lymphocytes . Itpkb pathway inhibition increases intracellular Ca21, induces apoptosis of activated T cells, and can control T-cell–mediated autoimmunity. In this study, we employed genetic and pharmacological approaches to inhibit Itpkb signaling as a means of controlling graft-versus-host disease (GVHD). The invention provides a novel class of compounds, pharmaceutical compositions comprising such compounds and methods of using such compounds to treat or prevent diseases or disorders associated with abnormal or dysregulated B cell activities, particularly diseases or disorders that involve aberrant activation of inositol 1,4,5-trisphosphate 3-kinase B (ITPKb).
