CC-90005 is a potent, selective and orally active inhibitor of protein kinase C-θ (PKC-θ), with an IC50 of 8 nM. CC-90005 shows selectivity for PKC-θ over PKC-δ (IC50=4440 nM). CC-90005 can inhibit T cell activation by IL-2 expression[1]. CC-90005 shows the exquisite selectivity of CC-90005, with IC50s for all other family members of >3 μM[1].CC-90005 is a moderate inhibitor of both CYP2C9 (IC50=8 μM) and CYP2C19 (IC50=5.9 μM) in human liver microsomes[1].CC-90005 inhibits IL-2 expression in LRS_WBC human PBMCs, with an IC50 of 0.15 μM[1].CC-90005 (1-10 μM; 24 h) inhibits T cell proliferation in PBMCs by 51% at 1 μM and 88% at 3 μM[1]. CC-90005 (3-30 mg kg; p.o. twice daily for 4 days) significantly reduces the popliteal lymph node (PLN) size in a model of chronic T cell activation[1].CC-90005 (100 mg kg; a single p.o.) significantly inhibits plasma and spleen IL-2 release by 51 and 54%, respectively[1].CC-90005 exhibits reasonable oral bioavailability (66 and 46%) and Cmax (1.18 and 1.2 μM) following oral administration (10 and 3 mg kg) in rat and dog, respectively[1].CC-90005 exhibits the mean residence time (0.52 and 2.0 h), CL (69.1 and 20.5 mL min kg) and Vss (2.11 and 2.44 L kg) following intravenous administration (2 and 1 mg kg) in rat and dog, respectively[1].

BMS-986251 is a potent and specific RORγt inverse agonist that exerts its action via oral administration. It shows an EC 50 of 12 nM for RORγt GAL4. In human whole blood assay, BMS-986251 effectively inhibits IL-17 with an EC 50 of 24 nM. Furthermore, BMS-986251 exhibits strong therapeutic effects in mouse acanthosis and Imiquimod-induced models, which are commonly used preclinical models for psoriasis.
Anticancer agent 63 (compound 3h) exhibits significant cytotoxic activity against multiple cancer cell lines, including SW480, HeLa, A549, and MCF-7, with IC 50 values of 4.9, 11.5, 9.4, and 3.4 μM, respectively, after 24 hours of treatment. In particular, Anticancer agent 63 induces apoptosis in MCF-7 cells by down-regulating Bcl-2 expression and up-regulating IL-2 and Caspase-3 expression. Additionally, Anticancer agent 63 demonstrates antioxidative properties [1].
