BMS 777607 is a substituted 2-aminopyridine shown to inhibit the RON and cMet receptor tyrosine kinases, for the treatment of solid tumors. BMS 777607 demonstrated ligand stimulated and constitutive Met phosphorylation, and inhibition of tumor cell proliferation, in preclinical studies. Preclinical data indicated that BMS 777607 inhibited RON, blocking the conversion of micrometastases to overt metastases by boosting antitumor immunity. Bristol-Myers Squibb conducted a phase I/II trial of BMS 777607 for the treatment of advanced solid tumors in Australia. As at December 2016, no recent reports of development had been identified for preclinical development in Cancer in the USA.

Scyllo-inositol (ELND005) is an inositol isoform. Inositol is a derivative of cyclohexane with six hydroxyl groups, making it a polyol. It also is known as a sugar alcohol, having exactly the same molecular formula as glucose or other hexoses. Scyllo-inositol (ELND005) is a naturally occurring plant sugar alcohol found most abundantly in the coconut palm. It appears to accumulate in a number of human tissues and biofluids through dietary consumption. It has traditionally been considered to be a B vitamin although it has an uncertain status as a vitamin and a deficiency syndrome has not been identified in man. Although scyllo-inositol (ELND005) at pharmacologic doses may alter myo-inositol levels and indirectly affect phosphatidyl-inositol signaling, its main effects are thought to be binding and inhibition of beta-amyloid 42 peptide aggregation and formation of beta-amyloid fibrils. In transgenic animals, scyllo-inositol (ELND005) reduced brain beta-amyloid concentrations and plaque burden, preserved synaptic density, and improved learning deficits. Scyllo-inositol (ELND005) also appears to neutralize toxic effects of beta-amyloid oligomers, including amelioration of oligomer-induced synaptic loss, long-term potentiation inhibition, and memory deficits. Scyllo-inositol (ELND005) is an attractive candidate as a potential disease-modifying oral treatment for Alzheimer disease.

Iincyclinide, also known as CMT-3 and COL-3, is an MMP inhibitor and a chemically-modified tetracycline with potential antineoplastic activity patented by Chas. Pfizer & Co. Incyclinide has been shown to experimentally suppress prostate cancer, colon adenocarcinoma and melanoma invasiveness in cell culture. Incyclinide is an especially effective inhibitor of the growth and viability of filamentous fungi. Unfortunately, in clinical trials, Iincyclinide failed to demonstrate efficacy in Lymphoma, Melanoma, Renal Cell Carcinoma, and some other tumors.

Valnivudine, also known as FV-100, a prodrug that has been indicated as a potential antiviral for the treatment of shingles (herpes zoster) that could both reduce the pain burden of the acute episode and reduce the incidence of post‐herpetic neuralgia compared to available treatments. Phase I clinical trial with FV100 showed safety and tolerability in healthy volunteers. Valnivudine also participated in phase III, where its efficacy was compared with valacyclovir; however, the study was terminated.

Apabetalone (RVX-208) is a small molecule BET bromodomain inhibitor selective for BRD4-BD2 undergoing clinical development as a potential therapy to enhance ApoA-I production and treat atherosclerosis and prevent cardiovascular disease events. Apabetalone increases apolipoprotein A-I and high-density lipoprotein cholesterol (HDL-Cholesterol) in vitro and in vivo which is believed to provide a new approach to treating atherosclerosis through the stimulation of reverse cholesterol transport. RVX-208 increased the Tm of all BET bromodomains, indicative of binding. RVX-208 competes for acetylated histone H4 peptide binding to both bromodomains of BRD4, similar to JQ-1, but with a preference for BD2 over BD1. RVX-208 also binds to the bromodomains of BRDs 2 and 3 with a similar preference for BD2 (Kd~5–30 nM) over BD1 (Kd~2–3 uM). Treatment of humans for 1 week with oral RVX-208 increased apoA-I, pre-beta-HDL, and HDL functionality. Resverlogix Corp. has commenced a Phase 3 clinical trial in cardiovascular disease patients with type 2 diabetes mellitus with a primary endpoint of time to first occurrence of Major Adverse Cardiac Events (MACE).

MIP-1095 I-123 is under investigation in clinical trial phase II to evaluate the safety and efficacy in combination with enzalutamide in patients with prostate-specific membrane antigen (PSMA)-avid metastatic castration-resistant prostate cancer who have progressed on abiraterone. It is known that MIP-1095 potently inhibited the glutamate carboxypeptidase activity of PSMA and when radiolabeled with 123I exhibited high affinity for prostate-specific membrane antigen (PSMA) on human prostate cancer LNCaP cells.

OC-459 is a highly potent and selective CRTH2 antagonist which is active on both the recombinant and native human receptor. The Atopix lead compound OC-459 is effective in improving lung function and symptoms in patients with atopic eosinophilic asthma. This group represents 40-50% of all asthmatics and the magnitude of improvement in the responder population is equivalent to high dose inhaled corticosteroids. OC-459 has also been shown to reduce both nasal and eye symptoms in allergic subjects exposed to grass pollen. Of particular interest is the ability of OC-459 to reduce the rate of respiratory infections, an effect related to reduction in Th2 immunity which has a damaging effect on host defence. OC-459 has also demonstrated an excellent safety profile in around 800 subjects exposed drug and no safety issues have been highlighted in long term toxicology. OC-459 is in Phase 2 clinical trial in patients with moderate to severe atopic dermatitis.

The antibiotic anthelmycin was first isolated by Hamill and Hoehn from culture filtrates of Streptomyces longissimus. Anthelmycin (hikizimycin) has also been isolated from the fermentation broth of Streptomyces sp., strain A-5 which was obtained from a soil sample collected at the Hikizi river-side, Kanagawa Prefecture, Japan, by Uchida K. et al. Anthelmycin (hikizimycin) is active against fungi, especially phytopathogenic fungi. The drug inhibits the growth of a number of prokaryotic and eukaryotic organisms and also has antihelminthic activity. Anthelmycin inhibits protein synthesis on both pro- and eukaryotic ribosomes by preventing the peptide bond-forming reaction. The drug is structurally similar to certain other 4-aminohexosyl cytosine antibiotics including blasticidin S, gougerotin, amicetin and bamicetin although unlike these compounds anthelmycin lacks an aminoacyl moiety. It is proposed that anthelmycin inhibits the ribosomal peptidyl transferase centre by associating with a site that overlaps the (related) ribosomal receptor site(s) for the other four inhibitors.
