Infiltrating myeloid derived suppressor cells and tumor-associated macrophages (TAMs) are important components of the immunosuppressive tumor microenvironment. We recently reported that tasquinimod, which binds to S100A9, impairs both infiltration and function of these cells.

Inhibition of S100A9 with tasquinimod demonstrates potent anti-tumor activity in pre-clinical models of multiple myeloma.

Presented at the Virtual Edition of the 25th European Hematology Association (EHA) Annual Congress Meeting, 2020.

However, Tasquinimod treatment of 4T1 tumor-bearing mice had a moderate anti-tumor activity which may be due to a limited activity on granulocytic MDSC accumulation.

Tasquinimod s100a9

These cells abundantly produce the protein S100A9 which has recently been implicated in the development of cancer. Tasquinimod (ABR-215050, Active Biotech, Lund, Sweden) is an investigational drug that binds the S100A9 protein and inhibits the interactions with its receptors. Aims Tasquinimod is an oral antiangiogenic agent, which has the potential for castration-resistant prostate cancer treatment. Tasquinimod binds to the regulatory Zn2+ binding domain of HDAC4 with Kd of 10-30 nM. Tasquinimod also is a S100A9 inhibitor.

We recently reported that tasquinimod, which binds to S100A9, impairs both infiltration and function of these cells.

• Talazoparib. PDE inhibitors. *Human In progress.

Thus binding of tasquinimod to S100A9, and thereby inhibiting its interaction with receptors on myeloid cells, is a possible mechanism for an altered migration of myeloid cells into the tumor. In the MC38-C215 tumors, however, the myeloid compartment of the TME was dominated by F4/80 + macrophages and this composition was stable over time and with respect to tumor size (from day 7 to day 14

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. View and buy high purity Tasquinimod from Tocris Bioscience.

2011-09-19 · Purpose The activity of the novel antitumor agent tasquinimod (TASQ) with S100A9 as a molecular target was investigated in men with metastatic castration-resistant prostate cancer (CRPC) and minimal symptoms. Patients and Methods We conducted a randomized, double-blind, placebo-controlled phase II trial in men assigned (at a ratio of two to one) to either oral once-daily TASQ 0.25 mg/d Paquinimod, also known as ABR‑215757, is a S100A9 inhibitor preventing S100A9 binding to TLR-4. Paquinimod reduces pathology in experimental collagenase-induced osteoarthritis.
