PF-04620110 is an orally active, selective and potent DGAT1 (Acyl-CoA:diacylglycerol acyltransferase 1) inhibitor that inhibits triacylglycerol synthesis in cells and in rodents. PF-04620110 inhibits DGAT-1 with an IC50 of 19 nM and shows high selectivity versus a broad panel of off-target pharmacologic end points. In vivo DGAT-1 inhibition has been demonstrated through reduction of plasma triglyceride levels in rodents at doses of ≥0.1 mg/kg following a lipid challenge. On the basis of this pharmacologic and pharmacokinetic profile, PF-04620110 has been advanced to human clinical studies. PF-4620110 had been in phase I clinical trials by Pfizer for the treatment of type 2 diabetes. But this research was discontinued in 2011.

DBPR-108 is a potent, selective, and orally bioavailable dipeptide-derived inhibitor of DPP4 with IC50 of 15 nM; no inhibition on DDP8 and DPP9, which is in phase I clinical trial as a potential treatment of type 2 diabetes.

BIIB-024, also known as MLN2480, and AMG 2112819, is an oral, selective pan-Raf kinase inhibitor. The Raf kinases (A-Raf, B-Raf and C-Raf) are key regulators of cell proliferation and survival within the mitogen-activated protein kinase (MAPK) pathway. The MAPK pathway is frequently disregulated in human cancers, often via activating mutations of Ras or Raf. BIIB-024 inhibits MAPK pathway signaling in BRAF mutant and some RAS mutant preclinical cancer models at concentrations that are tolerated in vivo. BIIB-024 is most potent in BRAF mutant melanoma models but also has single agent activity in some RAS mutant models. The combination of BIIB-024 with TAK-733 inhibits the growth of a broader range of RAS mutant tumor models than single agent BIIB-024, including primary human tumor xenograft models of melanoma and CRC. BIIB-024 is in phase I clinical trials for the treatment of malignant melanoma and solid tumours.

WP1066 is a cell-permeable AG490 tyrphostin analog that effectively inhibits the phosphorylation of Janus kinase 2 (JAK2) and its downstream signal transducer and activator of transcription 3 (STAT3) in a dose- and time-dependent manner. As a result, WP1066 concentrations in the low micromolar range induced time- and dose-dependent antiproliferative and proapoptotic effects in cancer cells. WP1066 has been used in Phase I trial studying the treatment of melanoma, brain cancer, solid tumors, and central nervous system neoplasms.

LY-3009120 is an orally available inhibitor of all members of the serine/threonine protein kinase Raf family, including A-Raf, B-Raf, and C-Raf protein kinases, with potential antineoplastic activity. Upon administration, pan-RAF kinase inhibitor LY3009120 inhibits Raf-mediated signal transduction pathways, which may inhibit tumor cell growth. Raf protein kinases play a key role in the RAF/mitogen-activated protein kinase kinase (MEK)/extracellular signal-regulated kinase (ERK) signaling pathway, which is often dysregulated in human cancers and plays a key role in tumor cell proliferation and survival. LY3009120 is being investigated in phase I clinical trial.

AVL-3288 is a type I selective positive allosteric modulator of α7 nACHRs. It represents a "first-in-class" drug for the treatment of cognitive deficits in CNS disorders such as schizophrenia and potentially other diseases of cognitive impairment such as Alzheimer’s disease and ADHD. AVL-3288 was successfully tested in representative animal models of cognitive dysfunction in schizophrenia, a disease where α7 nAChR function is impaired. To date, no specific treatments for cognitive deficits in schizophrenia exist and approved therapies do not satisfactorily improve cognition. AVL-3288 is currently in human phase I trials.

BCX-4430 hydrochloride is a salt of an antiviral adenosine analog BCX4430 (Immucillin-A) that acts as a viral RNA-dependent RNA polymerase (RdRp) inhibitor. It was developed as a potential treatment for deadly filovirus infections such as Ebola virus disease and Marburg virus disease but also demonstrated broad-spectrum antiviral effectiveness against a range of other RNA virus families, including, bunyaviruses, arenaviruses, paramyxoviruses, and coronaviruses. Biochemical, reporter-based and primer-extension assays indicate that BCX4430 inhibits viral RNA polymerase function, acting as a non-obligate RNA chain terminator. BCX4430 inhibits infection of distinct filoviruses in human cells. Post-exposure administration of BCX4430 protects rodents against Ebola and Marburg virus disease and cynomolgus macaques from Marburg virus when administered as late as 48 hours after infection. BCX4430 is highly active in a Syrian golden hamster model of yellow fever, even when treatment is initiated at the peak of viral replication. BCX4430 also showed efficacy against Zika virus in a mouse model.

ZSTK474 is a new PI3K inhibitor with strong antitumor activity against human cancer xenografts without toxic effects in critical organs. Specifically, ZSTK474 is an ATP-competitive inhibitor of class I phosphatidylinositol 3 kinase isoforms. ZSTK474 blocks VEGF-induced cell migration and the tube formation in human umbilical vein endothelial cells (HUVECs), and inhibits the expression of HIF-1α and secretion of VEGF in RXF-631L cells, exhibiting potent in vitro antiangiogenic activity. ZSTK474 demonstrated prophylactic efficacy in a rat model of rheumatoid arthritis (RA) through inhibition of T cell and FLS functions.

PU-H71 is experimental inhibitor of Hsp90. It is being tested in clinical trials against lymphoma and solid tumors.

APTO-253 is a novel small molecule that can induce expression of the genes that code for the Krüppel-like factor 4 (KLF4) master transcription factor and for the p21 cell cycle inhibitor protein, and can inhibit expression of the c-Myc oncogene, leading to cell cycle arrest and programmed cell death (apoptosis) in human-derived solid tumor and hematologic cancer cells. A Phase 1 study with APTO-253 was completed and demonstrated modest clinical activity in patients with colon cancer, acute leukemia, myelodysplastic syndrome, hematological malignancies and non-small cell lung cancers.
