ACT-451840 is a new compound with potent activity against sensitive and resistant Plasmodium falciparum strains. ACT-451840 has been used in trials studying malaria. ACT-451840 appears to have a distinct mode of action that sets it apart from current antimalarial drugs, including artemisinins. It has a rapid onset of action as well as activity on all blood-borne (erythrocytic) stages, which is retained against multiple resistant parasites, including artemisinin-resistant strains. Unlike the majority of antimalarial agents, ACT-451840 has the potential to block disease transmission due to its activity on gametocytes. he antimalarial activity of ACT-451840 was studied in an experimental induced blood stage malaria clinical trial performed in collaboration with MMV Medicines for Malaria Ventures at the laboratories of Professor James McCarthy, MBBS, MD of the Royal Brisbane and Women's Hospital in Herston, Australia. In the trial, ACT-451840 was safe and well tolerated and showed clinical efficacy against the early stages of P. falciparum infections. The PK/PD model developed from this proof-of-concept study with eight healthy subjects enabled prediction of therapeutic effects, with cure rates following 1 week of therapy (single daily doses) predicted to be equivalent to artesunate monotherapy.

Mitoglitazone (previously known as MSDC-0160 or CAY-10415) is a mTOT (mitochondrial target of thiazolidinediones) modulator that targets the mitochondrial pyruvate carrier (MPC), which is a key controller of cellular metabolism. MSDC-0160 is modulated MPC and act as insulin sensitizers without activating PPAR gamma. (Mitoglitazone exhibits very low binding affinity and activity at PPARγ). Mitoglitazone has been used in trials phase II studying the treatment of Type 2 Diabetes and Alzheimer's disease; the treatment for diabetes was discontinued. In addition, MSDC-0160 has demonstrated significant neuroprotective effects in the En1+/- mouse model of Parkinson’s disease via modulation of the mTOR-autophagy signaling cascade.

CC-220 is a potent cereblon modulating agent that displays anti-proliferative, pro-apoptotic and immunomodulatory activity on sensitive and resistant multiple myeloma cell lines. CC-220 is currently under clinical investigation for systemic lupus erythematosus and multiple myeloma as a single agent, or in combination with dexamethasone in patients who may have previously been exposed to pomalidomide. Comparable to other Cereblon-binding agents, ex vivo treatment of CC-220 on B-cells, T-cells, and monocytes leads to the degradation of the hematopoietic transcription factors Ikaros (IKZF1) and Aiolos (IKZF3). followed by disruption of the multiple myeloma promoting c-Myc/IRF4 axis.

ASC-09 orTMC-310911, a HIV protease inhibitor, participated in phase II clinical for the treatment of Human Immunodeficiency Virus Type 1. However, no recent development has been reported.

Pexmetinib (ARRY-614) is a potent, orally bioavailable, dual p38 MAPK/Tie-2 inhibitor with potential antineoplastic, anti-inflammatory and antiangiogenic activities. Pexmetinib inhibited leukemic proliferation, prevented activation of downstream effector kinases and abrogated the effects of TNF-alpha on healthy hematopoietic stem cells. In ex vivo stimulated human whole blood, LPS-induced cytokines was inhibited by Pexmetinib with an IC50 value ranging from 50-120 nM. ARRY-614 inhibited the release of IL-6 from SEA- or LPS-challenged mice with an ED50 value less than 10 mg/kg. Combining Pexmetinib with lenalidomide inhibited both pro-inflammatory cytokines and tumor growth in vivo with higher potency, compared with either agent alone. In dose escalation or expansion cohorts, treatment with Pexmetinib either once daily or twice daily was applied to forty-five patients. Pexmetinib reduced the levels of circulating biomarkers and the p38 MAPK activation of bone marrow.
