N,N-Dimethyl-5-Methoxytryptamine (aka 5-MeO-DMT) is a psychedelic of the tryptamine class. It is found in a wide variety of plant species, and a single psychoactive toad species, the Colorado River toad. Like its close relatives DMT and bufotenin (5-HO-DMT), it has been used as an entheogen in South America. It can also be found in the dart poison traditionally used by the Yanoama Indians of Upper Orinoco. It acts as a non-selective serotonin (5-HT) agonist. -MeO-DMT is O-demethylated by polymorphic cytochrome P450 2D6 (CYP2D6) to an active metabolite, bufotenine. 5-MeO-DMT is classified as a controlled substance in China, Australia, Sweden, Turkey, and the USA.

Androsterone, a neurosteroid, acts as a positive allosteric modulator of GABA(A) receptors, that can cross into the brain and could have effects on brain function. It was discovered, that the association of beta subunits with alpha subunits GABA(A) receptor affects the sensitivity of glycine receptors to androsterone. In spite of that, androsteron is considered as an inactive metabolite of testosterone. In addition, was studied that androsterone possessed anticonvulsant properties. Although of low potency, the androsterone was present in high abundance and was able to represent endogenous modulator of seizure susceptibility.

Muscimol is one of the principal psychoactive constituents of Amanita muscaria and related species of mushroom. Muscimol is a potent, selective agonist for the GABAAreceptors and displays sedative-hypnotic, depressant and hallucinogenic psychoactivity. The effects of the Amanita mushrooms begin 30–120 minutes after consumption and the effects last for 5–10 hours. Some of the desired effects include euphoria, dream-like (lucid) state of mind, out-of-body experiences, and synesthesia. Neutral effects include dizziness, clumsiness, the feeling of increased physical strength, loss of equilibrium, and a glassy-eyed stare. Calming effects may be felt, but completely opposite effects such as extreme energy bursts have been described. Negative effects include mild to moderate nausea, stomach discomfort, increased salivation, and muscle twitching or tremors. In large doses, strong dissociation or delirium may be felt.

Docebenone (AA-861) is a potent, selective and orally active 5-LO (5-lipoxygenase) inhibitor. T. vaginalis-derived secretory products (TvSP)-induced IL-8 production was efficiently inhibited when trichomonads were pretreated with docebenone. Docebenone increased [Ca(2+)](i) in Madin Darby canine kidney cells by releasing Ca(2+) from multiple internal stores in a manner independent of the formation of inositol-1,4,5-trisphosphate, followed by Ca(2+) entry from external medium. In animal model, it was shown that docebenone may prove useful in the treatment of acute pancreatitis. Docebenone showed a dose-dependent inhibition of slow reacting substance of anaphylaxis (SRS-A) release, with no effect on histamine release from passively sensitized guinea pig, monkey (M. irus) and human lung fragments. It markedly suppresses biosynthesis of the leukotrienes. This drug inhibits the release of histamine as well as SRS-A from lung fragments of anaphylactic monkey (M. mulatta) and in the Ca ionophore-stimulated rat peritoneal cavity. AA-861 suppressed the anaphylactically-induced airway resistance in mepyramine- and cimetidine-treated guinea pigs. These results suggest that AA-861 may be clinically effective for treating allergy-related asthma by modulating the 5-lipoxygenase pathway and that an inhibitory mechanism of histamine release by AA-861 may be present in some species. Docebenone has shown anti-inflammatory effects in several animal models following local dosing: phorbol ester-induced oedema and neutrophil influx in mouse skin, arachidonate-induced plasma extravasation in rabbit skin, the pleural reversed passive Arthus reaction in rats.

Fenretinide (4-HPR) is an orally-active synthetic phenylretinamide analogue of retinol (vitamin A) with potential antineoplastic and chemopreventive activities. Fenretinide binds to and activates retinoic acid receptors (RARs), thereby inducing cell differentiation and apoptosis in some tumor cell types. This agent also inhibits tumor growth by modulating angiogenesis-associated growth factors and their receptors and exhibits retinoid receptor-independent apoptotic properties. Phase III clinical trial data has suggested that fenretinide reduces breast cancer relapse in pre-menopausal women. Fenretinide is the most studied retinoid in breast cancer chemoprevention clinical trials due to its selective accumulation in breast tissue and its favorable toxicological profile. This agent showed a significative reduction of the incidence of second breast tumors in premenopausal women confirmed after 15-year followups. Fenretinide, a drug being developed by Sirion Therapeutics, slowed the progression of advanced dry age-related macular degeneration (AMD) by 45 percent for people receiving a higher dose of the treatment in a Phase II clinical trial. Sirion has been granted a Fast Track designation for the treatment by the FDA. Fenretinide is in phase II clinical trials for the treatment of B-cell lymphoma, chronic lymphocytic leukemia. It is also in phase I clinical trials for the treatment of cystic fibrosis.

Harmine (aka telepathine) is a fluorescent harmala alkaloid belonging to the beta-carboline family of compounds. It is a naturally occurring metabolite in a number of plants, notably the Middle Eastern plant harmal or Syrian rue (Peganum harmala) and the South American vine Banisteriopsis caapi. Harmine is a reversible inhibitor of monoamine oxidase A (MAO-A), but not MAO-B. Harmine has been found to have potential anti-cancer and neuroprotective properties, and also promotes differentiation of osteoblasts and chondrocytes while inhibiting osteoclastogenesis. Harmine has also been used as a C-11 labeled probe in positron emission tomography.

Dimpylate (diazinon) is a nonsystemic organophosphate insecticide, an inhibitor of the enzyme acetylcholinesterase (AChE), which hydrolyzes the neurotransmitter acetylcholine (ACh) in cholinergic synapses and neuromuscular junctions. This results in abnormal accumulation of ACh in the nervous system. Dimpylate was first registered for use in the USA in 1956. It was developed as an insecticide, acaricide, and nematicide for use on a variety of pests for control of soil insects and pests of fruit, vegetables, and forage and field crops. It had been used extensively in home and garden applications, in formulations designed to prevent such pests as crickets or cockroaches from infesting homes or offices, and in pet collars. Due to the emerging health and ecological risks posed by diazinon, manufacturers agreed to phase out and cancel all residential products. Manufacturing of indoor use products containing dimpylatewas discontinued in 2001; manufacture of non-agricultural outdoor use products containing dimpylate was discontinued in 2003.

Fenamole is a muscle relaxant. It is effectively inhibits muscle spasms at good levels for a four hours and at significant levels for six hours. Clinical benefits were derived in patients with spasticity-spasm for periods up to 24 hours after a single oral dose. Fenamole is relatively free of adverse side effects particularly in the central nervous system. It is a potent copper chelator. It was once investigated as a potential antirheumatic agent in man.
