Ipatasertib, an investigational Akt inhibitor, is currently in clinical development based on its potential to specifically target Akt in tumors with activated Akt signaling. Preclinical data have shown that ipatasertib selectively decreased cell viability and increased apoptosis in tumor cell lines characterized by activated Akt. Ipatasertib is advancing in clinical development including three Phase 2 trials in patients with breast cancer, gastric cancer and prostate cancer. The most commonly reported adverse events associated with Ipatasertib were Grade 1-2 diarrhea, nausea, fatigue, vomiting, decreased appetite and rash.

Anisodamine is a naturally occurring atropine derivative that has been isolated, synthesized and characterized by scientists in the People's Republic of China. Anisodamine is a non-specific cholinergic antagonist. Anisodamine has been shown to interact with and disrupt liposome structure which may reflect its effects on cellular membranes. Experimental evidence implicates anisodamine as an anti-oxidant that may protect against free radical-induced cellular damage. Its cardiovascular properties include depression of cardiac conduction and the ability to protect against arrhythmia induced by various agents. Anisodamine is a relatively weak alpha(1) adrenergic antagonist which may explain its vasodilating activity. Its anti-thrombotic activity may be a result of inhibition of thromboxane synthesis. Numerous therapeutic uses of anisodamine have been proposed including treatment of septic shock, various circulatory disorders, organophosphorus (OP) poisoning, migraine, gastric ulcers, gastrointestinal colic, acute glomerular nephritis, eclampsia, respiratory diseases, rheumatoid arthritis, obstructive jaundice, opiate addiction, snake bite and radiation damage protection. The primary therapeutic use of anisodamine has been for the treatment of septic shock. Several mechanisms have been proposed to explain its beneficial effect though most mechanisms are based upon the assumption that anisodamine ultimately acts by an improvement of blood flow in the microcirculation. Preliminary studies suggest another important therapeutic use of anisodamine is for the treatment of OP poisoning. Anisodamine has been employed therapeutically since 1965 in the People’s Republic of China primarily to improve blood flow in circulatory disorders such as septic shock, disseminated intravascular coagulation (DIC) and as an antidote to organophosphate poisoning.
AT-406 (DEBIO-1143, SM-406), is a potent and orally bioavailable Smac mimetic and an antagonist of the inhibitor of apoptosis proteins (IAPs). AT-406 inhibits cancer cell growth in various human cancer cell lines. It has good oral bioavailability in mice, rats, non-human primates, and dogs, is highly effective in induction of apoptosis in xenograft tumors, and is capable of complete inhibition of tumor growth. Debiopharm under a licence from Ascenta Therapeutics is developing AT-406 for the treatment of cancers.

Belnacasan (VX-765), and its active metabolite VRT- 043198, is a novel and irreversible IL-converting enzyme/ caspase-1 inhibitor. VRT-043198 exhibits 100- to 10,000-fold selectivity against other caspase-3, -6 and -9. It exhibited potent inhibition against ICE/caspase-1 and caspase-4 with Ki of 0.8 nM and less than 0.6 nM, respectively. And VRT-043198 also inhibits IL-1β release from both PBMCs and whole blood with IC50 of 0.67 uM and 1.9 uM, respectively. Belnacasan inhibits the release of IL-1, IL-18 and IL-33. Belnacasan has shown to inhibit acute partial seizures in preclinical models and has shown activity in preclinical models of chronic partial epilepsy that do not respond to currently available compounds for epilepsy. In addition, it seems to reduce disease severity and the expression of inflammatory mediators in models of rheumatoid arthritis and skin inflammation. Belnacasan had been in phase II clinical trials by Vertex for the treatment of epilepsy. However, this study has been terminated later.
8-Chloroadenosine-3',5'-cyclic-monophosphate (8-Cl-cAMP), an analog of c-AMP, is a novel antineoplastic agent. It has been shown to be effective against different human cancer cell lines modulating the cellular signal transduction pathway, thereby causing growth inhibition, cell differentiation, and apoptosis. 8-Cl-cAMP preferentially binds to the R2 subunit of protein kinase A (PKA) and induces rapid R2 up-regulation and eventual R1 subunit down-regulation. It has potent inhibitory effects on a wide variety of human cancer cell lines, with an IC50 ranging from 0.1 to 20 uM. The IC50 falls with the length of drug exposure. It can suppress c-myc and c-ras proto-oncogenes in vitro and in vivo. It was shown that 8-Cl-cAMP induces cell growth inhibition through AMP-activated protein kinase (AMPK) activation with p38 MAPK acting downstream of AMPK in this signaling pathway. 8-Cl-cAMP induced apoptosis, apparently through activation of the p38 MAPK pathway by inducing progressive phosphorylation of the p38 mitogen-activated protein kinase (MAPK), via activation of AMPK by its metabolite 8-Cl-adenosine. 8-Cl-cAMP does not significantly inhibit the growth of NIH 3T3 cells, rat kidney fibroblasts, mammary epithelial cells, or peripheral blood lymphocytes, nor does it inhibit the growth of parental cells whose progeny have been transformed. Such selectivity makes it an attractive candidate for cancer therapy suggesting that it should not cause the toxicity of conventional cytotoxic agents but should inhibit tumor growth. 8-Cl-cAMP has been evaluated in phase I/II clinical trials.

Rislenemdaz, also known as MK-0657 or CERC‐30, is an orally active, selective NMDA receptor subunit 2B (NR2B) antagonist which was a study for the treatment of Parkinson's disease and major depressive disorder (MDD). The data from the phase I clinical trials have shown that drug was not effective in improving motor symptoms in patients with Parkinson disease. In case of using this drug to treat MDD, in spite of the Missing Primary Endpoint in phase II clinical trials, it was shown, that MK-0657 had possessed a potential clinical meaningfulness, that is why it was suggested to continue studying it for MDD patients.

Lefradafiban, an orally active prodrug of fradafiban, is a novel glycoprotein (IIb/IIIa) inhibitor for the treatment of unstable angina. The pharmacokinetic and pharmacodynamic properties of lefradafiban were assessed in 130 healthy male volunteers who received a single dose of 10, 50, 75, 100, or 150 mg or multiple doses of 25, 50, 60, 75, 90, or 100 mg three times daily for one week. After both single and multiple doses, receptor occupancy and plasma lefradafiban levels correlated with platelet aggregation. Lefradafiban had been in phase II clinical trials by Boehringer Ingelheim for the treatment of thrombosis. However, it has been terminated.

Dalcetrapib (JTT-705) is a modulator than an inhibitor of cholesteryl ester transfer protein (CETP) activity and it may interact with and decrease CETP activity by a unique mechanism without an off-target effect. Dalcetrapib increased high-density lipoprotein (HDL) cholesterol levels but did not reduce the risk of cardiovascular events. It is in phase III of clinical trials for the treatment of acute coronary syndrome.

Merestinib (LY2801653) is a small molecule that has been shown in vitro to be a reversible type II ATP-competitive slowoff inhibitor of MET tyrosine kinase with a dissociation constant (Ki) of 2 nM, a pharmacodynamic residence time (Koff) of 0.00132 min−1 and a half-life (t1/2) of 525 min. Preclinical testing also has shown merestinib to inhibit several other receptor tyrosine oncokinases including MST1R, FLT3, AXL, MERTK, TEK, ROS1, NTRK1/2/3, and DDR1/2 and the serine/threonine kinases MKNK1/2. Merestinib is being investigated in a phase II clinical trials in patients with biliary tract cancer, non-small cell lung cancer and solid tumours.
Psilocybin is a naturally occurring psychedelic prodrug compound produced by more than 200 species of mushrooms, collectively known as psilocybin mushrooms. Once ingested, psilocybin is rapidly metabolized to the psilocin, which then acts on serotonin receptors in the brain. Psilocybin was identified as the active hallucinogenic compound in magic mushrooms in 1959, but humans have used assorted psilocybin mushrooms in religious ceremonies since prehistoric times. In the 1960's psilocybin was marketed for use as a treatment for various psychoses, however, it was withdrawn from the market when the regulatory environment changed. Recently there has been as renewed interest in studying the medicinal uses of psilocybin for treatment of anxiety, depression, migraine headaches, addictions, and other neuropsychiatric conditions.
