AZD-6482 is being developed by AstraZeneca to evaluate its therapeutic effects in the treatment of thrombosis. AZD-6482 is essentially a PI3K-beta inhibitor. It is a PI3Kβ inhibitor with IC50 of 10 nM, 8-, 87- and 109-fold more selective to PI3Kβ than PI3Kδ, PI3Kα and PI3Kγ in cell-free assays. by targeting PI3Kβ, AZD-6482 specifically inhibits thrombosis without interfering with normal haemostasis. Therefore, AZD-6482 is used as an anti-thrombotic drug for the prophylaxis of thrombotic disorders. AZD-6482 was in phase I trials by AstraZeneca for the prevention of thrombosis. However, the study was discontinued.

TAK-715 (Takeda) was a p38 MAPK inhibitor that had been implicated in the pro-inflammatory cytokine signal pathway, the inhibitors of which are potentially useful for the treatment of chronic inflammatory diseases such as rheumatoid arthritis and inflammatory bowel disease. Inhibition of p38 MAPK and LPS-stimulated release of TNF-α from human monocytic THP-1 cells by TAK-715 was demonstrated in vitro; its inhibition of LPS-induced TNF-α production was demonstrated in vivo in mice. TAK-715 had showed good bioavailability in mice and rats and efficacy in a rat adjuvant-induced arthritis model. It was advanced into clinical Phase II trials but was discontinued, as it did not satisfy criteria for further development.
