Sulbutiamine (isobutyryl thiamine disulfide) is a lipophilic derivative of thiamine. It is available over-the-counter in several countries either as a component of nutritional supplements or as a pharmaceutical preparation. Arcalion (Sulbutiamine) is prescribed as a treatment to help patients with a range of conditions such as asthenia, chronic fatigue, diabetes, hypothyroidism, renal disease, fibromyalgia, and depression (post partum). It remedies the symptoms of weakness by increasing focus, strength (both physical and mental), and energy, making you more alert, less lethargic, and more upbeat whilst also helping to stabilize sleeping patterns. In addition, this medication can also help a patient`s memory, and strengthen thinking processes. Some patient`s have even reported slight eyesight improvements. This product is also popular with athletes as a nutritional supplement as it is a vitamin compound which will not show up in competitive sports blood testing. It can help to achieve your maximum potential and replenish energy after strenuous activities, making it possible to maintain your edge. The presence of sulbutiamine in urinary doping control samples was monitored to evaluate the relevance of its use in sports. The motivating, confidence enhancing effects of sulbutiamine are thought to be related to its ability to enhance dopamine sensitivity. In animal models sulbutiamine has been shown to increase the number of dopamine binding sites (specifically D1) in the prefrontal cortex, this effect is achieved through reduction of dopamine release. Sulbutiamine could be best thought of as a dopamine modulator rather than a compound that directly inhibits or enhances the release of dopamine. Additionally sulbutiamine has been found to enhance memory, possibly by cholinergic transmission. Research indicates that high affinity choline uptake (HACU) was moderately increased in rodent brains following sulbutiamine consumption. However it should be noted the doses used were high (300 mg/kg).

GW-501516 is a peroxisome proliferator-activator receptor-delta agonist for the potential treatment of dyslipidemia, hyperlipidemia, metabolic diseases and cardiovascular diseases. GW501516 treatment is associated with significant improvements in multiple lipid profile components (TG, LDL-C, HDL-C, free fatty acids and apoB, apoA-I and apoA-II) and a shift in LDL particle size from small dense to larger, less dense particles. Despite these promising early results, the further investigation and development of GW501516 was discontinued after observations in animal studies of its association with the rapid induction of cancers in several organs (liver, stomach, tongue, skin, bladder, ovaries, womb and testes).

Meclofenoxate (INN, BAN) (brand name Lucidril), also known as centrophenoxine, is a cholinergic nootropic used as a dietary supplement and drug in the treatment of symptoms of senile dementia and Alzheimer's disease. Meclofenoxate has been shown in studies to be effective in enhancing the memory and in improving the cognitive functions of the elderly. Some studies even suggest that Meclofenoxate has the ability to reverse the signs of brain aging. While claims about its ability as a nootropic agent have not been fully established in clinical trials, some studies do strongly suggest that it is indeed very effective in improving memory retention and recall. Meclofenoxate HCL Powder for Injection is also indicated for the following conditions: comma; skull and brain trauma; following a stroke; encephalopathy; mental disorders (in combination with psychotropic agents); mental and psychomotor retardation in children; brain intoxication; alcohol psychoses; neuritis and polyneuritis. The main mechanism of action of Meclofenoxate is generally believed to be cholinergic in nature. As an efficient transporter of DMAE, Meclofenoxate encourages the production of choline in the brain, which is then synthesized into acetylcholine. The more acetylcholine neurotransmitters in the brain, the better and more efficient the cognitive functions will be. Meclofenoxate also increases cellular membrane phospholipids

Vincamine is the major alkaloid of Vinca minor. Although vincamine has been used therapeutically for almost three decades, the exact mechanisms of action and its effects are still unknown. Vincamine is a peripheral vasodilator that increases blood flow to the brain. Vincamine is beneficial to the nervous system's cells feeding and protecting processes and is utilized as an adjuvant in case of cerebrovascular insufficiency, age-related psycho-behavioral disorders, post concussion syndrome in head trauma, in case of post-stroke sequels. Vincamine may be used as a dietary nootropic supplement.

Aniracetam is a nootropic drug. It behaves as a positive modulator of AMPA-sensitive glutamate receptors. Aniracetam is clinically used in patients with mild to moderate senile dementia of the Alzheimer type. In Japan, the drug was prescribed for eight years to treat emotional disturbances, such as depressed mood and anxiety/agitation, but not memory impairment following cerebral infarction. Aniracetam (Draganon®) has been withdrawn from the Japanese market because of the unexpected failure in the latest placebo-controlled double-blind study. Animal studies demonstrated that aniracetam has clinical potential in personality disorders, anxiety, depression, posttraumatic stress disorder, attention-deficit/hyperactivity disorder, autism, negative symptoms of schizophrenia, and sleep disorders.

Oxiracetam (ISF 2522) is a water-soluble ampakine of the nootropic racetam chemical class. Oxiracetam is a positive AMPA modulator similar in mechanism and potency (but not the binding site) to both piracetam and aniracetam but may have an additional benefit of increasing glutamate, acetylcholine, and D-aspartic acid release from activated but not resting neurons. Oxiracetam has been proved as an efficient memory enhancer if taken consistently. Additionally, studies have revealed positive impacts on demented patients in the long term. Thus, the drug enhances an overall quality of life of patients suffering from ADHD, dementia, and other neurological problems. Oxiracetam is one of the most popular nootropics, well known and highly regarded for its outstanding cognitive enhancement properties and mild stimulant capability. It has also been proven to be safe and well tolerated even at high dosages, and its moderate cost, ready availability and “stackability” make it a must-have for many nootropic users.

Oxitriptan is an aromatic amino acid with antidepressant activity. In vivo, oxitriptan is converted into 5-hydroxytryptamine (serotonin) as well as other neurotransmitters. Oxitriptan may exert its antidepressant activity via conversion to serotonin or directly by binding to serotonin receptors within the central nervous system. It is used as an antiepileptic and antidepressant. Oxitriptan is a worthwhile addition to the limited treatments available for obsessive-compulsive disorder and panic disorder, two psychiatric disorders which have previously been difficult to manage pharmacologically. Possible gastrointestinal side effects are: nausea, vomiting, abdominal pain, constipation or flatulence, which tend to disappear with continued treatment or, in any case, dose reduction. Other undesirable effects such as anorexia, xerostomia, tachycardia, extrasystoles, dizziness, headache, lightheadedness, tremor or myalgia may occur.
