Tasquinimod (ABR-215050, Active Biotech, Lund, Sweden) is an investigational drug that binds the S100A9 protein and inhibits the interactions with its receptors. Aims To investigate the anti-tumor effects of tasquinimod as a single agent and in combination with standard therapeutics in pre-clinical models of MM.

Tasquinimod treatment ameliorated the myeloproliferation in JAK2 V617F mice comparable to leukocyte, hemoglobin, and platelet counts in controls (Figure 7F; Figures S7G and S7H).

Tasquinimod is an oral antiangiogenic agent, it is also a S100A9 inhibitor. Tasquinimod binds allosterically within the regulatory Zinc domain of HDAC4 with a Kd of 10-30 nM, which results in inhibition of co-localization of N-CoR/HDAC3, thereby inhibiting deacetylation of histones and HDAC4 client transcription factors, such as HIF-1α. Abstract 121: S100A9 inhibitor Tasquinimod: A novel strategy to inhibit small cell lung cancer progression and metastasis July 2019 DOI: 10.1158/1538-7445.AM2019-121 The infiltration of myeloid cells helps tumors to overcome immune surveillance and imparts resistance to cancer immunotherapy.

S100A9 is a potential target of tasquinimod that may be involved in immunomodulatory activity, 8 and S100A9 has been shown to regulate accumulation of MDSCs. 4,9 Tasquinimod binds to S100A9, 10 and blocks the interaction of this ligand with its receptors, including receptor for advanced glycation end product (RAGE) and Toll-like receptor (TLR)-4 and EMMPRIN. Quinoline-3-carboxamides Such as Tasquinimod Are Not Specific Inhibitors of S100A9 Blood Adv . 2018 May 22;2(10):1170-1171. doi: 10.1182/bloodadvances.2018016667.

The molecular target of tasquinimod is S100A9 (MRP-14), a suitable therapeutic target in oncology that, as suggested by tumor growth is impaired in S100A9 knockout mouse models. Tasquinimod binds to histone deacetylase, [4] a potential target, as has been described in various in vitro studies, which may result in reductions in stress-mediated hypoxia signaling and angiogenesis induction in the

Tasquinimod (a quinoline-3-carboxyamide) is a small molecule immunotherapy with demonstrated effects on the tumor microenvironment (TME) involving immunomodulation, anti-angiogenesis and inhibition of metastasis. A target molecule of tasquinimod is the inflammatory protein S100A9 which has been shown to affect the accumulation and function of suppressive myeloid cell subsets in tumors.

2018 May 22;2(10):1170-1171. doi: 10.1182/bloodadvances.2018016667. Inhibition of S100A9 with tasquinimod demonstrates potent anti-tumor activity in pre-clinical models of multiple myeloma. Cindy Lin , Aubrey Leso , Matthew Rosenwasser , Marie Torngren , Helena Eriksson , Yulia Nefedova. Presented at the Virtual Edition of the 25th European Hematology Association (EHA) Annual Congress Meeting, 2020. S100A9 share a higher degree of functional homology than of sequence similarity.26 In addition, the binding of tasquinimod to S100A9 does not appear to be species specific.24 Thus, the dosage regimens of tasquinimod treatment was based on the pharmacokinetics parameters (bioavailability) and the tolerated doses in animals.

Thus, strategies to modulate the effects of these immune cells may offer a potential therapeutic benefit. We report here that tasquinimod, 2014-11-01 · tasquinimod. S100A9 interacts with pro-inflammatory receptors Toll-like receptor 4 (TLR4) and receptor of advanced glycation end products (RAGE), and this interaction is inhibited by the specific binding of tasquinimod to S100A9 [22-23]. These receptors are expressed on the surface Tasquinimod, an oral quinoline-3-carboxamide, binds to S100A9 and the S100A8/A9 complex in the presence of Zn 2+ and Cu 2+ and thus blocks the interaction of S100A9 with TLR4 or RAGE, inhibiting TNF-α release in an S100A9-dependent model in vivo . Tasquinimod is a second-generation quinolone-3-carboxamide agent that targets S100A9, a calcium-binding protein expressed on myeloid-derived suppressor cells.

Tasquinimod also targets infiltrating myeloid cells, and modulates local tumour immunity by blocking the interaction between S100A9 and its ligands receptor of advanced glycation end products and Toll-like receptor 4.

Mark; Abstract The quinoline-3-carboxamides (Q compounds) are a family of small molecules with immunomodulatory functions that have shown efficacy in various murine models of inflammatory diseases. Tasquinimod has previously been studied as an anti-cancer agent in patients with other cancers, including a phase 3 randomized trial in patients with metastatic prostate cancer that showed an improvement in radiographic progression-free survival.

Given the fact that in order to act as a DAMP, S100A9 should reach extracellular space, the presence of S100A9 homodimer in the extracellular milieu was shown.
