Dimesone is a synthetic glucocorticoid with anti-inflammatory and anti-allergic activity.

Gestaclone was developed as a progesterone receptor agonist; however, this compound has never been marketed. Information about the current use of this compound is not available.

Salvinorin A has been reported to be the most potent naturally occurring hallucinogen, with an effective dose in humans in the 200- to the 1,000-μg range when smoked; it has been reported to induce an intense hallucinatory experience in humans, with a typical duration of action being several minutes to an hour or so. Salvinorin A is a highly selective agonist of the kappa-opioid receptor (KOR) with few off-target effects. It is a potent and selective dilator of the cerebral vasculature, exhibits rapid penetration through the blood-brain barrier, has potent anti-inflammatory properties, and has the ability to preserve neurovascular unit integrity. As such, salvinorin A is an ideal compound for the prevention and treatment of cerebral vasospasm following subarachnoid hemorrhage.

Dideoxyadenosine (2′,3′-dideoxyadenosine) is a prodrug form of didanosine (2',3'-dideoxyinosine), a nucleoside reverse transcriptase inhibitor analog of adenosine. 2',3'-Dideoxyadenosine and 2',3'-dideoxyinosine were shown to be equally effective in the inhibition of HIV proliferation in human T cells. Dideoxyadenosine competitively inhibits adenylyl cyclase, thereby reducing levels of cyclic adenosine monophosphate (cAMP). By inhibiting cAMP-mediated gene activation in tumor cells, this agent may retard tumor cell proliferation. 2',3'-dideoxyadenosine inhibits retroviral DNA synthesis and mRNA expression in T cells exposed to the virus that causes acquired immunodeficiency syndrome, and affords such cells long-term protection in vitro under conditions of substantial viral excess. 2',3'-dideoxyadenosine appears to completely block reverse transcription from viral RNA to viral DNA. 2',3'-dideoxyadenosine was also shown not only to possess antibacterial activity in vitro against a variety of Enterobacteriaceae, but also to be effective in vivo, dideoxyadenosine was active in experimental mouse infections by the oral route against 5 Salmonella strains, 2 of 3 Arizona strains, 5 of 7 Citrobacter strains, 3 of 8 Klebsiella strains, 3 of 5 Escherichia strains, 1 of 3 Shigella strains, and 3 of 15 Serratia strains at concentrations generally well below the toxic level.

EC17 (also known as Folate-FITC) is conjugate consisting of fluorescein isothiocyanate (FITC) conjugated with folate with potential antineoplastic activity. EC17 binds to folate receptors, which are overexpressed on the surfaces of many cancer cells including kidney and ovarian cancer cells. Once bound to the cancer cell through the folate moiety of the conjugate, circulating anti-fluorescein antibodies recognize and bind to the FITC moiety, resulting in antibody-dependent cellular cytotoxicity. EC17 is participating in phase II clinical trials for the treatment of patients with endometrial cancer, endometriosis, lung cancer, renal cell carcinoma. In January 2018, On Target Laboratories initiated a phase III trial to evaluate the safety and efficacy of EC17 injection for patients with ovarian cancer.

Phencynonate (PHH) is a novel anticholinergic compound. It is structurally similar to scopolamine, possesses both muscarinic and nicotinic antagonistic properties as well as anti-NMDA properties. It has been developed as a safe and effective drug for the prevention of motion sickness in tablet form, it also demonstrates clear anticonvulsant effectiveness after soman poisoning in a rat model. S-isomer was more effective against motion sickness and had not anxiogenic action at therapeutic doses. S-isomer has the higher affinity and activity for mAChR in cerebral cortex and acted as a competitive mAChR antagonist. PHH was able to suppress chronic unpredictable mild stress (CUMS)-induced oxidative stress and enhance the antioxidant capacity and antioxidant proteins activity, such as superoxide dismutase 2 (SOD2) and peroxiredoxin 6 (Prdx6). PHH ameliorated CUMS-induced depressive phenotypes by up-regulating SIRT6 deacetylation activity. PHH-mediating SIRT6 pathway is required for antidepressant response and PHH can be used as a novel therapeutic to effectively treat depression. Phencynonate is in phase III clinical trials for the treatment of vertigo.

Tandamine was developed as a selective serotonin reuptake inhibitor for the treatment of depression. Tandamine participated in clinical trials in hospitalized depressed patients, where it showed that the well-tolerated drug could be of some benefit for retarded depressions. In addition, was found in human volunteers, that tandamine possessed significant anticholinergic activity, to reduce appetite and to produce sedation. However, this drug has never been marketed.

FILOCICLOVIR, also known as cyclopropavir, is a guanosine nucleoside analog. It is an antiviral drug ready for phase II clinical trials for the treatment of cytomegalovirus infection.
