Description:

WARNING: This product is for research use only, not for human or veterinary use.

PI3065 is a p110δ isoform of phosphoinositide-3-OH kinase (PI(3)K) inhibitor. Inhibitors against the p110δ isoform of phosphoinositide-3-OH kinase (PI(3)K) have shown remarkable therapeutic efficacy in some human leukaemias. As p110δ is primarily expressed in leukocytes, drugs against p110δ have not been considered for the treatment of solid tumours. p110δ inactivation in regulatory T cells unleashes CD8(+) cytotoxic T cells and induces tumour regression. p110δ inhibitors can break tumour-induced immune tolerance and should be considered for wider use in oncology

Biological target:
PI-3065 is a potent inhibitor of PI3K p110δ, with IC50 and Ki values of 5 nM and 1.5 nM.
In vitro activity:
It was addressed whether PI-3065 directly affected CD8+ T cells in vitro. It has been previously shown that after 3–4 rounds of cell division, discordant silencing of TCF1 becomes apparent in sibling cells as a result of unequal transmission of PI3K protein levels between daughter cells. To address whether blockade of PI3Kδ with PI-3065 affected asymmetrical expression of TCF1 in activated T cells, splenic CD8+ T cells were labeled with Tag-it-violet and stimulated for 5 days with anti-CD3 and anti-CD28-coupled to beads in the presence or absence of PI-3065. While after 3–4 divisions, TCF1 was, as expected, reduced in a proportion of the control cells, those treated with PI-3065 maintained expression of TCF1 for longer (figure 2A, C), implying that PI3Kδ blockade promotes their self-renewal capacity, possibly also in vivo, thereby promoting tumor immunity. J Immunother Cancer. 2020; 8(2): e000693. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7583804/
In vivo activity:
It has been previously demonstrated that inactivation of PI3Kδ in mice can significantly reduce the growth rate of inoculated solid tumors. The tumor growth rates of mice treated daily with either PI-3065 (PI3Kδ inhibitor) or vehicle (dosing control) in the 4T1 breast tumor model (figure 1) were examined. Confirming previous studies, it was observed that treatment with PI-3065 resulted in a significant reduction in tumor growth rate in the 4T1 model, (figure 1B). It was observed that treatment with PI-3065 led to CD8+ T cell-dependent control of primary tumor growth (figure 1C) and reduced metastatic burden (figure 1D). Overall, these data demonstrate a direct or indirect effect of PI-3065 on the ability of CD8+ T cells to mount an effective antitumor response.
