MSA-2 is a potent and orally available non-nucleotide STING agonist.

HPK1-IN-7 is an orally active HPK1 inhibitor. It shows selectivity against IRAK4 (59 nM) and GLK (140 nM).

PD-1 PD-L1-IN-32 (compound A56) is a potent inhibitor of PD-1 PD-L1 with an IC50 value of 2.4 nM, demonstrating significant anticancer activity. It effectively suppresses tumor growth in the hPD-L1 MC38 humanized mouse model and exhibits negligible toxicity to the normal functions of the mice [1].

(R)-IDO/TDO-IN-1 (compound 25), an indoleamine-2,3-dioxygenase (IDO) inhibitor, demonstrates good pharmacokinetic properties and exerts anti-tumor effects in the MC38 xenograft model. This compound exhibits synergy when combined with the anti-PD-1 monoclonal antibody (SHR-1210) [1].

HDAC-IN-53 is an orally active, selective inhibitor of HDAC1-3, with IC50 values of 47 nM, 125 nM, and 450 nM, respectively. It exhibits no inhibitory effects on class II HDACs (HDAC4, 5, 6, 7, 9; IC50 >10 μM). The compound induces caspase-dependent apoptosis and significantly hampers the growth of human tumor xenografts in nude mice and murine tumor growth in immune-competent mice with MC38 colon cancer [1].

Nidanilimab (CAN04) is a fully humanized IL1RAP monoclonal antibody with a Kd value of 1.10 pM. It exhibits antitumor activity by disrupting the IL1α and IL1β signaling pathways and inducing the immune system to destroy tumor cells. Nidanilimab can be used to study solid cancers, such as non-small cell lung cancer (NSCLC) and pancreatic ductal adenocarcinoma (PDAC).

LYP-IN-4 (compound D14), a reversible and selective lymphotyrosine phosphatase (LYP) inhibitor (Ki=1.34 μM, IC50=3.52μM), regulates TCR signaling, increases PD-1 PD-L1 expression, and strengthens anti-tumor immunity. It also stimulates T cell activation, impedes M2 macrophage polarization, and suppresses tumor progression in MC38 isogenic mouse models.
