(3R)-5,6,7-trihydroxy-3-isopropyl-3-methylisochroman-1-one enhanced the therapeutic efficacy of anti-PD1 antibody through inhibiting PI3K δ/γ.

Conclusions: Our results provided proof of concept for a new combination strategy involving the use of a selective inhibitor of PI3Kδ/γ to inhibit the function of MDSCs to enhance tumor responses to immune checkpoint blocking antibodies. PMID: 31691624 [PubMed - as supplied by publisher]
