AL3818 (anlotinib) is a receptor tyrosine kinase inhibitor targeting vascular endothelial growth factor receptors (VEGFR1, VEGFR2/KDR, and VEGFR3), stem cell factor receptor (C-kit), platelet-derived growth factor (PDGFβ), and fibroblast growth factor receptors (FGFR1, FGFR2, and FGFR3). Anlotibib is a kind of innovative medicines approved by State Food and Drug Administration（SFDA:2011L00661) which was researched by Jiangsu Chia-tai Tianqing Pharmaceutical Co., Ltd. Phase III development is underway for the treatment of thyroid cancer, gastric cancer, leiomyosarcoma; non-small cell lung cancer; synovial sarcoma; thyroid cancer etc.

Icotinib is an orally available quinazoline-based inhibitor of epidermal growth factor receptor. It selectively inhibits the wild-type and several mutated forms of EGFR tyrosine kinase. The major organ of icotinib metabolism is the liver, with the primarily enzymes being CYP2C19 and CYP3A4 from the cytochrome P450 monooxygenase system. Icotinib Hydrochloride was approved for the treatment of patients with advanced stage Nonsmall cell lung cancer by the State Food and Drug Administration (SFDA) of China. The major drug related adverse reactions of the traditional cytotoxic agents include rash, diarrhea, severe bone marrow suppression, neuropathy, hair loss, and gastrointestinal reactions. Icotinib is under investigation as an active agent against other EGFR mutation-positive cancers, like lung adenocarcinoma, oesophageal cancer, nasopharyngeal cancer and others.

Ginsenoside Rg3 (Rg3) is one of the most effective steroidal saponins extracted from Ginseng, a common Traditional Chinese medicine (TCM) herb which tonifies Qi in TCM theory and inhibits tumors. Rg3 suppresses tumor growth and tumor angiogenesis. For its significant antitumor effects, Rg3 has been used in clinical trials in combination with chemotherapy regimens. 20(S) and 20(R) forms of ginsenosides are stereoisomers of each other that depend on the orientation of the C-20 hydroxyl in ginsenosides. In general, the 20(S) compounds have been shown to possess better anti-proliferative effects than their 20(R) counterparts whereas 20(R) compounds such as 20(R)-Rg3 have been shown to inhibit cancer cell invasion and metastasis. Ginsenoside Rg3 regulates voltage-gated ion channels such as Ca(2+), K(+), and Na(+) channels, and ligand-gated ion channels such as GABAA, 5-HT3, nicotinic acetylcholine, and N-methyl-D-aspartate (NMDA) receptors through interactions with various sites including channel blocker binding sites, toxin-binding sites, channel gating regions, and allosteric channel regulator binding sites when the respective ion channels or receptors are stimulated with depolarization or ligand treatment. Shenyi capsule which contains ginsenoside Rg3 as the main ingredient has been approved by China Food and Drug Administration (CFDA) to be used clinically for cancer treatment.

Rociletinib is a novel, potent, small molecule, third generation TKI that irreversibly binds and inhibits EGFR with the common activating (L858R, Del19) and T790M resistance mutations. The proposed indication of rociletinib is for the treatment of patients with mutant EGFR NSCLC who have been previously treated with an EGFR-targeted therapy and have the T790M mutation as detected by an FDA approved test. The results from two Phase 2 studies show that rociletinib 625 mg BID treatment has a favorable benefit:risk profile in patients with recurrent T790M-positive mutant EGFR NSCLC based on clinically meaningful and durable responses and a well-established and acceptable safety profile in this patient population with terminal lung cancer. In May 2016, Clovis Oncology, Inc. announced it has terminated enrollment in all ongoing sponsored studies of rociletinib, including TIGER-3, after the company was notified at meeting with the FDA that it could anticipate receiving a Complete Response Letter (CRL) for the rociletinib NDA on or before the PDUFA date of June 28, 2016. Clovis has also withdrawn its Marketing Authorization Application of rociletinib with European regulatory authorities.

Protodioscin is a steroidal saponin compound found in a number of plant species, most notably in the Tribulus, Trigonella and Dioscorea families. Extracts from T. terrestris standardised have been demonstrated to produce proerectile effects in isolated tissues and aphrodisiac action in several animal species. Protodioscin have shown cytotoxic effects against a number of leukemia and solid tumors cell lines.

Efaproxiral is a synthetic, small molecule, radiation-sensitising agent being developed by Allos Therapeutics primarily for the treatment of cancer. It works by binding and allosterically stabilising deoxyhaemoglobin in hypoxic regions of tumour tissue. This increases oxygen uptake of the tumour tissue and restores its sensitivity to radiation therapy, making therapy potentially more successful. But no benefit was seen for efaproxiral in phase III clinical trials. The only serious adverse effect detected was hypoxaemia. Efaproxiral is explicitly excluded from the 2012 World Anti-Doping Agency list of Prohibited Substances and is explicitly included in the Prohibited Methods section M1 as a forbidden procedure to alter the oxygen-haemoglobin dissociation curve in order to allosterically modify haemoglobin.

PR-69 (Doranidazole) is a hypoxic radiosensitizer, and is a derivative of 2-nitroimidazole intended to reduce neurotoxicity due to its blood brain barrier (BBB) impermeability. Several studies have shown that doranidazole has a radiosensitizing effect under hypoxia, both in vitro and in vivo. Based on these studies, a phase III trial of doranidazole against advanced pancreatic cancer was performed; it was demonstrated that treatment with doranidazole following radiation significantly improved the tumor mass reduction rate and extended patient survival. Various results have suggested that doranidazole has promising potential for hypoxia-targeting chemoradiotherapy.

Nedaplatin is a second-generation cisplatin analogue with antineoplastic activity. nedaplatin forms reactive platinum complexes that bind to nucelophillic groups in DNA, resulting in intrastrand and interstrand DNA cross-links, apoptosis and cell death. It is currently registered for the treatment of various cancers (head and neck, testicular, lung, ovarian, cervical, non-small-cell lung) in Japan. The most commonly reported adverse reactions include nausea, vomiting, loss of appetite and hair loss. Nedaplatin may also cause nephrotoxicity at therapeutic doses, especially in patients with deteriorating renal function.

Amrubicin is a totally synthetic 9-aminoanthracycline anticancer drug, which is approved in Japan for the treatment of small cell and non-small cell lung cancer. Upon administration amrubicin is reduced to its C-13 hydroxy metabolite, amrubicinol. The cytotoxicity of amrubicinol in vitro is 10 to 100 times greater than that of amrubicin. Thus, the anticancer activity of amrubicin is considered to derive from this active metabolite. The mechanism of action of the drug is related to the inhibition of topoisomerase II by stabilizing the cleavable complex.

Acivicin is a modified amino acid and structural analog of glutamine, that irreversibly inhibits glutamine-dependent amidotransferases involved in nucleotide and amino acid biosynthesis. Acivicin is a potent antitumor agent that induces apoptosis in human lymphoblastoid cells. Phase I dose-escalating studies conducted in cancer patients administered acivicin showed reversible, dose-limiting CNS toxicity, characterized by lethargy, confusion and decreased mental status.
