Amustaline (S-303) is a quinacrine mustard compound with potential antineoplastic activity. Amustaline binds to, intercalates and crosslinks DNA and RNA. This agent is mainly used for ex vivo purposes, specifically for the inactivation of pathogens such as viruses, protozoa and bacteria in red blood cells (RBCs). When S-303 is added to red blood cells, the compound rapidly passes through membranes, including those of cells and viral envelopes, due to its amphipathic character, and intercalates into helical regions of the nucleic acids of pathogens and white blood cells. TERCEPTTMBlood System usingamustaline (S-303) and glutathione (GSH) was able to inactivate high levels of DENV and ZIKV in RBCs. S-303 system has been shown to effectively inactivate a broad spectrum of pathogens, while maintaining RBC quality.

Amotosalen (S-59, psoralen derivative), a chemical capable of binding to nucleic acids is added to platelets. UVA illumination (320 – 400 nm wavelengths) of amotosalen-treated platelet components induces covalent cross-linking of any nucleic acids to which amotosalen is bound; thereby, preventing further replication. Amotosalen is used in the INTERCEPT process to cross-link DNA and RNA. Amotosalen has protective activity against pathogens such as bacteria, viruses, protozoa, and leukocytes. Prior to administration amotosalen is added to plasma and platelets, then in vivo this agent penetrates pathogens and targets DNA and RNA. Upon activation by ultraviolet A light, amotosalen forms interstrand DNA and RNA crosslinks and prevents replication. Thus, the pathogen-inactivation system using amotosalen/ultraviolet A offers the potential to mitigate the risk of ZIKV transmission by plasma and platelet transfusion. Inactivation of leukocytes can prevent graft versus host disease upon transfusion.

Alagebrium (formerly known as ALT-711) - is one of the better known compounds discovered and developed with the intent of repairing a type of accumulated damage that leads to age-related degeneration. In this case, the damage is the buildup of extracellular protein crosslinks, and amongst them the type known as advanced glycation endproducts. The formation of advanced glycation end-products is associated with arterial stiffness in experimental models and alagebrium, an advanced glycation end-product cross-link breaker, has been shown to reduce arterial stiffness in elderly subjects. Alagebrium is an AGE-lowering agent with beneficial effects in renal structural and functional parameters in diabetes, decreased diabetes-accelerated atherosclerosis, and age-related myocardial stiffening. ALT-711 exhibits a structural homology to thiamine, and it was suggested to interfere with thiamine metabolism. Enzyme kinetic experiments showed that ALT-711 dose-dependently decreased TDPK activity with K(i)s, calculated by different experiments and fitting models ranging from 0.88 to 1.09 uM. Alagebrium has been investigated for the treatment and prevention of aging, heart failure, physical activity, diabetic nephropathy, and cardiovascular disease, among others. However, this research has been discontinued.

CYC-116 is a novel, ATP-competitive, pyrimidine drug that is taken by mouth as a capsule. The drug is a selective agent that potently inhibits the enzymes Aurora kinases and VEGFR-2 kinase at comparable levels with a range of 19 to 69 nanomolar. Median potency of CYC-116 in cancer cells is approximately 300 nanomolar. CYC-116 has demonstrated a broad spectrum of potent cytotoxic activity against human tumor cell types. Non-clinical efficacy of CYC-116 has been demonstrated by the oral route using mouse leukemia models, in which increased survival was observed, and human solid tumor xenograft models, in which reductions in tumor growth were observed. Cancer cell types that appear to be particularly sensitive to CYC-116 are leukemia, non-small cell lung cancer and pancreatic cancer. CYC-116 works by affecting the cell cycle progression of cancer cells before they enter mitosis or divide to create daughter cancer cells. The mechanism of action of CYC-116 affects cancer cells in several ways. CYC-116-treated cells display delayed entry into mitosis; defective polymerization of tubulins, or proteins that make up microtubules which are the target of the taxane drugs; changes in the function of the centrosome, or the cell's microtubule organizing center; and formation of the mitotic spindle, or the highway along which chromosomes and cellular materials are transported from the mother cell to the daughter cells. After cancer cells are treated with CYC-116, their spindle checkpoint is inactivated resulting in inhibition of cytokinesis or the process by which a mother cell divides. These defects result in the generation of polyploidy or cells with more than two chromosome sets, multinucleated cells or cells with multiple cores and apoptosis or cancer cell death. In a mouse model of leukemia CYC116-treatment induced decreases in tumor cell volume and infiltration of leukemic cells in the bone marrow and resulted in an increase in life span. No significant effects on body weight or normal bone marrow cells were observed at effective doses of CYC-116. Tumor neovascularization, or creation of new blood vessels around a tumor, was significantly reduced in a dose dependent manner. The data confirm that CYC-116 acts as a dual mitotic and angiogenesis inhibitor, a combination of anti-cancer mechanisms which could have therapeutic benefit in the clinic. CYC-116 is currently being studied in a Phase 1 trial in patients with solid tumors at Roswell Park Cancer Institute in Buffalo, New York, and South Texas Accelerated Research Therapeutics (START) in San Antonio. The study is designed to identify the maximum tolerated dose of CYC-116 and evaluate its pharmacokinetic, pharmacodynamic and anti-tumor effects.

Clobuzarit (Clozic) is a compound originally developed for the treatment of atherosclerosis. It was later found to possess antirheumatic and weak anti-inflammatory properties and was evaluated as a disease-modifying antirheumatic drug. Adverse side effects observed in clinical trials have forced the withdrawal of clobuzarit from further consideration.

Dopropidil is an antianginal calcium ion modulating agent, possessing intracellular calcium antagonist activity and anti-ischemic effects in several predictive animal models. Dopropidil had similar vasorelaxant potency as bepridil in the rabbit aorta depolarized by K(+), but was less potent than verapamil, nifedipine, and diltiazem in this respect. Dopropidil has an unusual pharmacological profile, which includes both antiarrhythmic and anti-atherosclerotic properties. In vitro studies show that dopropidil inhibits both smooth and cardiac muscle contractions induced by activation of voltage operated channels, and inhibits the “slow” inward calcium current in the latter tissue, suggesting that dopropidil blocks membrane calcium ion channels. Dopropidil-induced inhibition of collagen and thrombin-induced platelet aggregation at higher concentrations also suggests actions other than calcium channel blockade since platelets lack voltage operated channels. Dopropidil also reduces fatty streak formation in the aorta of cholesterol fed rabbits, an action which may be related to the demonstrated antioxidant properties of this compound. Long-term toxicity studies in rats and dogs showed only mild toxic signs, notably a decrease in food consumption, slight sedation, and some vomiting in the latter species. Dopropidil had been in phase II clinical trials for the treatment of angina pectoris and arrhythmias. However, these studies were discontinued.
