METHYLENETETRAHYDROFOLIC ACID, L-(+), an endogenous biomodulator that was developed under the brand name modufolin or arfolitixorin by the Isofol Medical. Arfolitixorin is developed to increase the efficacy of standard of care chemotherapy for advanced colorectal cancer. This drug is currently being studied in a global phase 3 clinical trial. Besides, the drug successfully completed phase II as rescue therapy for osteosarcoma. 21 May 2019 Isofol Medical has received clinical patent protection for the arfolitixorinin USA. It relates to a method of increasing blood concentration of deoxyuridine, a blood biomarker for inhibition of tumor growth in human cancer treatment.

Detirelix is a synthetic decapeptide containing five D-amino acids. It is a very potent Gonadotropin-releasing hormone (GnHR) antagonist. The acute effects of detirelix were consistent with peripheral vasodilation. Subchronic effects were associated with inhibition of pituitary gonadotropic and gonadal hormone secretion. As long-acting GnRH antagonist detirelix can rapidly suppress gonadotropin secretion, inhibit follicular development, and prevent ovulation. It can be used as luteolytic agent. A projected use is for the treatment of sex hormone-releasing diseases, as part of anticancer hormone therapy of sex-hormone-dependent tumors.

Deltibant is the bradykinin receptor antagonist. It was found to be a potent and selective inhibitor of the depressor response to bradykinin in the anaesthetized rat and rabbit. Deltibant affords significant protection against traumatic shock where bradykinin plays an important role in tissue injury. Such protection may be achieved through inhibition of neutrophil-endothelial interaction and protection of vascular endothelial function. Deltibant may have some effect on survival in patients with systemic inflammatory response syndrome and gram-negative sepsis. Kinin-kallikrein system could be involved in cerebral edema - treatment with deltibant appeared to alter the natural history of traumatic brain contusions by preventing the 2 degrees brain swelling. In addition, deltibant obviated the need for surgery in the majority of treated patients. Deltibant could act on the cerebral vasculature to limit dys-autoregulation and brain swelling or on the blood brain barrier to reduce cerebral edema. Deltibant has been in phase II clinical trials for the treatment of pain, immune-inflammatory diseases and stroke. However, this research has been discontinued.

Delparantag is a novel, salicylamide-derived, small molecule. Delparantag is heptagonist. It acts as universal anticoagulation-reversing agent. Delparantag neutralized the antithrombotic, anticoagulant, and bleeding effects of heparins as effectively as protamine sulfate and may be slightly more efficacious against low-molecular-weight heparins (LMWHs). This agent was designed to restore coagulation by specifically binding to the pentasaccharide and disrupting unfractionated heparin and LMWH interaction with antithrombin. Delparantag has been shown to completely reverse the anticoagulant effects of heparin and normalize blood-clotting time in six human subjects in less than 10 minutes in a phase IB clinical trial. In clinical trial studies, safety was ascertained by blood pressure measurements and efficacy was determined by measuring blood clotting time (aPTT, Activated Partial Thromboplastin Time, or ACT, Activated Coagulation Time). Plasma half-life elimination of delparantag is between 3 and 5 min. Development was recently paused due to hypotension noted in the studies although this may be avoided with longer administration times and will require further investigation.

ABT-510 is an anti-angiogenesis compound that was under development by Abbott for the treatment of solid tumours, lymphoma and melanoma. It is a synthetic peptide that mimics the anti-angiogenic activity of the endogenous protein thrombospondin-1 (TSP-1). ABT-510 inhibits the actions of several pro-angiogenic growth factors important to tumor neovascularization; these pro-angiogenic growth factors include vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF)), hepatocyte growth factor (HGF), and interleukin 8 (IL-8).

Fluorescein Lisicol (NRL972) is a fluorescent-labelled bile acid analog that is used as an investigational marker for liver function, specifically hepatic biliary transporter function. Fluorescein Lisicol has been used in trials investigating the pharmacokinetics of hepatic cirrhosis, viral hepatitis, non-alcoholic steatohepatitis and non-alcoholic fatty liver disease.
