KX-02 is a compound demonstrating dual inhibitory activity against Src kinase and tubulin polymerization. It readily crosses the blood-brain-barrier in mice. It is under development for the treatment of solid tumors.

HCI-2084 (wider known as TP-0903) is developing by Tolero Pharmaceuticals for the treatment of different cancers. HCI-2084 is a small molecule AXL receptor tyrosine kinase (RTK) inhibitor. AXL is involved in maintaining a mesenchymal phenotype in cancer cells that enhanced cell survival in stressed environments, and increased resistance to targeted therapies compared to epithelial cells. AXL overexpression has been observed in multiple tumor types that have acquired resistance to various agents. TP-0903 is participating in phase I/II clinical trial in patients with previously treated chronic lymphocytic leukemia (CLL). This study will investigate the safety, pharmacokinetics, pharmacodynamics, and clinical activity of TP-0903. Besides, phase I is currently being conducted in patients with advanced solid tumors in the presence of TP-0903. In addition, TP-0903 was investigated in neuroblastoma (NB) cells, where this drug makes NB cells more vulnerable to the conventional chemotherapeutics.

GSK126, a potent, highly selective, S-adenosyl-methionine-competitive, small-molecule inhibitor of EZH2 methyltransferase activity, decreases global H3K27me3 levels and reactivates silenced PRC2 target genes. GSK126 effectively inhibits the proliferation of EZH2 mutant DLBCL cell lines and markedly inhibits the growth of EZH2 mutant DLBCL xenografts in mice. Pharmacological inhibition of EZH2 activity may provide a promising treatment for EZH2 mutant lymphoma. EZH2 inactivation by GSK126 is also effective in killing MM cells and CSCs as a single agent or in combination with bortezomib. Clinical trial of GSK126 in patients with MM may be warranted. GSK126 is undergoing phase I trials for hypermethylation-related cancers. GSK126 is in phase I diffuse large B cell lymphoma and follicular lymphoma. GSK126 inhibits cell migration and angiogenesis in solid tumor cell lines through down-regulation of VEGF-A expression. Thus, it may be considered as a novel anticancer drug candidate for solid tumor.

Russian Pharmaceutical Technologies is developing alofanib, a first in class, allosteric inhibitor of fibroblast growth factor receptor type 2 (FGFR2) for the treatment of tumours expressing FGFR2, including ovarian cancer, colorectal cancer and lung cancer. Alofanib is a potential allosteric inhibitor of FGFR2 used in oncology. Alofanib has potent effects on ovarian cancer growth in preclinical studies.The inhibitor blocks the extracellular part of the receptor and prevents its binding with the ligand. Alofanib suppressed proliferation of endothelial cells, their migration activity, and ability to form vessellike structures in vitro and significantly decreased the number of microvessels in Matrigel implant and in ovarian cancer (SKOV-3) xenograft in vivo. The results indicate that Alofanib can inhibit angiogenesis.

MK-3281 is a potent and orally bioavailable inhibitor of HCV NS5B polymerase which combined excellent cell-based potency with good pharmacokinetic properties in preclinical species. MK-3281 was efficacious in the chimeric mouse model of HCV infection.
