Delanzomib (CEP-18770), a proteasome inhibitor, was being developed by Cepahlon (a subsidiary of Teva) for the treatment of cancer and immunological disorders. Delanzomib (CEP-18770) induces apoptotic cell death in multiple myeloma (MM) cell lines and in primary purified CD138-positive explant cultures from untreated and bortezomib-treated MM patients. In vitro, Delanzomib (CEP-18770) has a strong antiangiogenic activity and potently represses RANKL-induced osteoclastogenesis. Delanzomib represses the proteasomal degradation of a variety of proteins, including inhibitory kappaBalpha (IkappaBalpha), resulting in the cytoplasmic sequestration of the transcription factor NF-kappaB; inhibition of NF-kappaB nuclear translocation and transcriptional up-regulation of a variety of cell growth-promoting factors; and apoptotic cell death in susceptible tumor cell populations. In vitro studies indicate that this agent exhibits a favorable cytotoxicity profile toward normal human epithelial cells, bone marrow progenitors, and bone marrow-derived stromal cells relative to the proteasome inhibitor bortezomib. Delanzomib has been in phase II clinical trials for the treatment of multiple myeloma (MM). However, this research has been discontinued. Currently Delanzomib is on Phase I clinical trial for Non-Hodgkin's lymphoma and Solid tumours.
ENMD-2076 is an orally-active, Aurora A/angiogenic kinase inhibitor. urora kinases are key regulators of mitosis (cell division), and are often over-expressed in human cancers. ENMD-2076 also targets the VEGFR, Flt-3 and FGFR3 kinases, which have been shown to play important roles in the pathology of several cancers. ENMD-2076 is tested in phase 2 clinical trials against ovarian cancer, breast cance, hepatocellular carcinoma and other malignancies.

Indolapril (CI-907) is a new orally active prodrug of nonsulfhydryl angiotensin-converting enzyme (ACE) inhibitor, developed by Warner-Lambert/Parke-Davis Pharmaceutical Research for treating hypertension. Indolapril is epimer of trandolapril, well-known ACE inhibitor currently in the market for hypertension treatment. Indolapril (Monoester form) and it’s active component (diacid form) produced concentration related ACE inhibition in guinea-pig serum (IC50 for monoester -- 0.1 mkM and for diacid -- 2.6 nM). In isolated rabbit aortic rings and in rat and dog autonomic studies, Indolapril is highly specific in suppressing the contractile or pressor responses to angiotensin I. In two-kidney, one-clip Goldblatt hypertensive rats, single daily doses (0.03-30 mg/kg p.o.) produced dose-dependent decreases in blood pressure; 3 mg/kg lowered blood pressure to normotensive levels. In the spontaneously hypertensive rat, subacute administration of Indolapril produced the same decrease in blood pressure as that obtained in the renal hypertensive rat. In diuretic-pretreated renal hypertensive dogs, 10 mg/kg normalized blood pressure. For equivalent drops in blood pressure, heart rate increases were less in Indolapril than in enalapril-treated renal hypertensive dogs. No side effects were observed with CI-907 in any of the conscious animals. The antihypertensive response to Indolapril (0.03-1.0 mg/kg p.o.) was found to correlate with inhibition of vascular tissue ACE, but not plasma or brain ACE in two-kidney, one-clip renal hypertensive rats.

ABC-294640 is an orally bioavailable and selective sphingosine kinase-2 (SphK2) inhibitor with IC50 of approximately 60 uM. ABC-294640 inhibits SK2, a lipid kinase that catalyzes formation of the lipid signaling molecule sphingosine 1-phosphate (S1P). S1P promotes cancer growth, and proliferation and pathological inflammation, including TNFα signaling and other inflammatory cytokine production. Specifically, by inhibiting the SK2 enzyme, ABC-294640 blocks the synthesis of S1P which regulates fundamental biological processes such as cell proliferation, migration, immune cell trafficking and angiogenesis, and are also involved in immune-modulation and suppression of innate immune responses from T cells. Preliminary evidence suggests that because of its specificity for targeting SK2, rather than SK1, ABC-294640 may have a better therapeutic ratio than nonspecific sphingosine kinase inhibitors or those targeting only SK1. Oral administration of ABC-294640 to mice bearing mammary adenocarcinoma xenografts results in dose-dependent antitumor activity associated with depletion of S1P levels in the tumors and progressive tumor cell apoptosis. Therefore, this newly developed SK2 inhibitor provides an orally available drug candidate for the treatment of cancer and other diseases. ABC-294640 has completed multiple successful pre-clinical studies in inflammatory, GI, radioprotection and oncology models, as well as a Phase I clinical study in cancer patients with advanced solid tumors.

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.

Fiboflapon sodium (GSK2190915) is a high affinity 5-lipoxygenase-activating protein inhibitor being developed for the treatment of asthma. The compound was originally developed by Amira Pharmaceuticals. Fiboflapon sodium (GSK2190915) exhibits excellent preclinical toxicology and pharmacokinetics in rat and dog. GSK2190915 also demonstrated an extended pharmacodynamic effect in a rodent bronchoalveolar lavage (BAL) model. Oral administration of Fiboflapon sodium (GSK2190915) (1 mg/kg) resulted in sustained inhibition of ex vivo ionophore-challenged whole blood LTB4 biosynthesis with >90% inhibition for up to 12 h and an EC50 of approximately 7 nM. When rat lungs were challenged in vivo with calcium-ionophore, Fiboflapon sodium inhibited LTB4 and cysteinyl leukotriene (CysLT) production with ED50s of 0.12 mg/kg and 0.37 mg/kg, respectively. Fiboflapon sodium is in Phase-II for Asthma (Adjunctive treatment) in Poland, Ukraine, Bulgaria, USA, United Kingdom and Canada (PO).

AFN-1252 (now known as Debio-1452) is an antibiotic drug which is in phase II of clinical trials for the treatment of Staphylococcal skin and skin structure infections. The drug was effective in vitro against all isolates of S.aureus and its effect was explained by inhibition of enoyl-acyl carrier protein Reductase (FabI).
