AZD5672 was developed by AstraZeneca for the treatment of rheumatoid arthritis. It was found that the drug inhibits P-glycoprotein and is a CCR5 antagonist. Exists hypothesis that inhibition of CCR5 can bring benefits in the treatment of rheumatoid arthritis. In July 2009, Phase-II for Rheumatoid arthritis was discontinued.

AZD-1981, developed by AstraZeneca, is a potent (binding IC50 of 4nM), fully reversible, functionally non-competitive antagonist of human CRTh2. It blocks agonist-induced human eosinophil CD11b expression, shape change (including in whole blood), and chemotaxis as well as an basophil shape change and Th2-cell chemotaxis at IC50's of 8.5-50nM. Potency is similar across species as is plasma protein binding (~97%). AZD-1981 is a weak (10s of μM) inhibitor in vitro of CYP2C9, OATP1B1 and UGT1A1 as well as an inducer of CYP3A4. AZD-1981 was well tolerated and no safety concerns were identified.There was no beneficial clinical effect of AZD-1981, at a dose of 1000 mg twice daily for 4 weeks, in patients with moderate to severe COPD. AZD-1981 has being discontinued for asthma and chronic obstructive pulmonary disease. AstraZeneca is collaborating with Johns Hopkins University for the development of AZD-1981 in the treatment of chronic idiopathic urticaria. It is in phase II clinicals studies for the treatment of Urticaria.

Nivocasan (aka GS-9450) was discovered by LG Life Sciences and developed by Gilead Sciences. Nivocasan is an irreversible inhibitor of caspase 1, 8, and 9, and therefore able to prevent apoptosis. Nivocasan has been investigated as a treatment option for Hepatic fibrosis and Non-alcoholic steatohepatitis related to Hepatitis C infection. It had advanced to Phase II clinical trials before the development program was suspended.

Simenepag (AGN-210676) is a a small molecule selective prostaglandin EP2 agonist with EC50 of 5 nM. Allergan was developing simenepag for the treatment of glaucoma and ocular hypertension.

BNC105P, a vascular disrupting agent, is a disodium phosphate ester prodrug of BNC105. BNC105P is a tubulin polymerization inhibitor that suppresses cancer cell proliferation. BNC105P participated in phase I/II trial for patients with metastatic renal cell carcinoma. Although the primary endpoint was not met in an unselected population, correlative studies suggested several biomarkers that warrant further prospective evaluation. Besides, BNC105P was involved in phase II clinical trial as second-line chemotherapy for advanced malignant pleural mesothelioma. The drug was safe and tolerable, but the sole response was insufficient to warrant further research as a single agent. In addition, BNC105P in combination with Ibrutinib was studied in phase I trials for patients with chronic lymphocytic leukemia to determine the preliminary assessment of the efficacy.
