Bromebric Acid (Cytembena) is a derivative of bromoacrylic acid with cytostatic and antineoplastic activity. Chemical structure of Bromebric Acid is not related to any previous antineoplastic agent. In animal tumor screens, Jelinek and Semonsky noted antineoplastic activity of Cytembena against sarcoma 180, atlenocarcinoina of the lactic gland in mice, Ehrlich’s ascitic carcinoma, Yoshida’s ascitic sarcoma, and Zojdeln’s heap

Oglufanide, an angiogenesis inhibitor, an immunomodulator, that originally was developed and registered in Russia under the brand name timogen. Oglufanide inhibits vascular endothelial growth factor (VEGF), which may inhibit angiogenesis. This agent has also been reported to stimulate the immune response to hepatitis C virus and intracellular bacterial infections. Oglufanide was studied in the USA for the treatment of cancer, and in September 2001, it was granted Orphan Drug designation for the treatment of ovarian cancer. In addition, in Australia this drug was involved in phase II clinical trial for the treatment of hepatitis C. Oglufanide is also participated in phase III trials for patients with Kaposi's sarcoma, however, this study was discontinued.

Cemadotin (LU103793) is a cytotoxic water-soluble pentapeptide analogue of dolastatin 15. The dolastatin peptides were originally isolated from the shell-less mollusc Dolabella auricularia. Cemadotin blocks cells at mitosis. It exerts its antitumor activity by suppressing spindle microtubule dynamics through a distinct molecular mechanism by binding at a novel site in tubulin. Cemadotin was in phase II clinical trials as a promising cancer chemotherapeutic agent. However, this agent appears to be inactive in the treatment of advanced non-small-cell lung cancer and other tumors and this research has been discontinued.

Beloranib (also known as ZGN-433 or CKD-732), a fumagillin anticancer drug that initially was developed by CKD Pharmaceuticals for the treatment of solid tumors. Beloranib is a potent inhibitor of methionine aminopeptidase 2 (MetAP2), an enzyme that modulates the activity of key cellular processes that control metabolism. This drug was studied for the treatment of Prader-Willi syndrome and obesity caused by hypothalamic injury, including craniopharyngioma-associated obesity and severe obesity in the general population. European Commission has granted orphan drug designation for beloranib for the treatment of craniopharyngioma, a rare form of benign brain tumor and for the treatment of Prader-Willi syndrome. Beloran participated in phase III clinical trials to evaluate efficacy and safety in obese adolescent and adult subjects with Prader-Willi Syndrome, but these studies were terminated. In 2016, Zafgen, the company developed the drug, based on discussions with the regulatory authority and review of obstacles, costs and development timelines to gain marketing approval for beloranib, has decided to discontinue further development of the drug.

Nogalamycin is an unusual anthracycline antineoplastic antibiotic isolated from the bacterium Streptomyces nogalater. Nogalamycin intercalates into DNA and interacts with topoisomerase I, thereby inhibiting DNA replication and repair and RNA and protein synthesis. Nogalamycin contains two saccharides. The neutral monosaccharide attaches to the D ring, similar to the aminoglycoside moieties of the doxorubicin class, while the second, basic saccharide attaches to the phenolic group on the A ring in the ortho position to form a unique family of hexacyclic anthracyclines. Nogalamycin is potent antibacterial and antitumor agent. Nogalamycin was markedly cytotoxic in vitro and was active against several tumor systems in vivo.

Linsitinib is an inhibitor of the insulin receptor and the insulin-like growth factor 1 receptor, which may result in the inhibition of tumor cell proliferation and the induction of tumor cell apoptosis. Linsitinib is in phase II clinical trials for the treatment of metastatic prostate carcinoma, gastrointestinal stromal tumors and other cancers. Common adverse events included fatigue, nausea hyperglycaemia and anorexia.

Picoplatin is a sterically hindered platinum (II) complex with antineoplastic properties developed for the treatment of cis-platin-resistant cancer. Picoplatin alkylates DNA, forming both inter- and intra-strand cross-linkages, resulting in inhibition of DNA replication and transcription, and the induction of apoptosis. However, in Phase III trials, picoplatin failed to meet its primary endpoint for advanced cell lung cancer. It remains in development for other cancers.

Foretinib is an orally available multikinase inhibitor that targets c-MET and VEGFR2 with high affinity, which may result in the inhibition of tumor angiogenesis, tumor cell proliferation and metastasis. Foretinib is an experimental drug candidate for the treatment of cancer. It was in Phase II trials for the treatment breast cancer, non-small cell lung cancer, gastric cancer, head and neck cancer and papillary renal-cell carcinoma. The most frequent adverse events of any grade associated with foretinib were fatigue, hypertension, gastrointestinal toxicities, and nonfatal pulmonary emboli.

Mivobulin is a synthetic water-soluble colchicine analog with the broad antitumor activity that competitively binds tubulin at the colchicine-binding site and inhibits tubulin polymerization. Cancer cells exposed to Mivobulin isethionate accumulate in the M phase of the cell cycle and subsequently die. Preclinical studies have demonstrated that Mivobulin isethionate is able to cross the blood-brain barrier. Importantly, Mivobulin isethionate demonstrated significant antitumor activity in a broad spectrum of murine and human tumor models that were cross-resistant to vincristine, cisplatin, vinblastine, navelbine, and doxorubicin and in tumor cell lines exhibiting multidrug resistance owing to P-glycoprotein overexpression. In animal studies, the activity of Mivobulin isethionate was largely independent of the route of drug administration but favored a prolonged treatment schedule. Unfortunately, in clinical trials, Mivobulin fail to demonstrate the significant activity

Bisnafide (previously known as DMP 840), a bis-naphthalimide derivative that was developed by Bristol-Myers Squibb as a potential anticancer agent. Bisnafide acts as DNA intercalator and topo II inhibitor. This drug participated in phase I clinical trials in pediatric patients with refractory solid tumors. However, further, development has been discontinued.
