Prucalopride is a drug acting as a selective, high affinity 5-HT4 receptor agonist which targets the impaired motility associated with chronic constipation, thus normalising bowel movements.

Properties Suppliers

Prulifloxacin is an older synthetic chemotherapeutic antibiotic of the fluoroquinolone drug class. It is a prodrug which is metabolized in the body to the active compound ulifloxacin. It has been approved for the treatment of uncomplicated and complicated urinary tract infections, community-acquired respiratory tract infections and gastroenteritis, including infectious diarrheas.

Pseudoephedrine is a sympathomimetic drug of the phenethylamine and amphetamine chemical classes. It may be used as a nasal/sinus decongestant, as a stimulant, or as a wakefulness-promoting agent. Pseudoephedrine acts on α- and β2-adrenergic receptors, to cause vasoconstriction and relaxation of smooth muscle in the bronchi, respectively. pseudoephedrine is a stimulant, but it is well known for shrinking swollen nasal mucous membranes, so it is often used as a decongestant. It reduces tissue hyperemia, edema, and nasal congestion commonly associated with colds or allergies. Other beneficial effects may include increasing the drainage of sinus secretions, and opening of obstructed Eustachian tubes. The same vasoconstriction action can also result in hypertension, which is a noted side effect of pseudoephedrine.Pseudoephedrine is also indicated for vasomotor rhinitis, and as an adjunct to other agents in the optimum treatment of allergic rhinitis, croup, sinusitis, otitis media, and tracheobronchitis.It is recommended that pseudoephedrine not be used in patients with: diabetes mellitus, cardiovascular disease, severe or uncontrolled hypertension, severe coronary artery disease, prostatic hypertrophy, hyperthyroidism, closed angle glaucoma, or by pregnant women.

Psilocin, an aromatic compound, is a psychedelic mushroom alkaloid. It is found in most psychedelic mushrooms together with its phosphorylated counterpart psilocybin. It is the pharmacologically active agent in the body after ingestion of psilocybin or some species of psychedelic mushrooms. It is rapidly dephosphorylated in the body to psilocin which acts as a 5HT2A, 5HT2C and 5HT1A agonist. It is structurally similar to serotonin (5-HT), differing only by the hydroxyl group being on the 4-position rather than the 5 and the dimethyl groups on the nitrogen. Its effects are thought to come from its partial agonist activity at 5-HT2A serotonin receptors in the prefrontal cortex. It has no significant effect on dopamine receptors and only affects the noradrenergic system at very high dosages.

Properties Suppliers

Psilocybine is a naturally occurring psychedelic compound produced by more than 200 species of mushrooms, collectively known as psilocybin mushrooms. As a prodrug, psilocybine is quickly converted by the body to psilocin, which has mind-altering effects similar (in some aspects) to those of LSD, mescaline, and DMT. This chemical reaction takes place under strongly acidic conditions, or under physiological conditions in the body, through the action of enzymes called alkaline phosphatases. Psilocybin is an alkaloid that is soluble in water, methanol and aqueous ethanol, but insoluble in organic solvents like chloroform and petroleum ether. Psilocybine is a tryptamine compound with a chemical structure containing an indole ring linked to an ethylamine substituent. It is chemically related to the amino acid tryptophan, and is structurally similar to the neurotransmitter serotonin. Psilocybine is a member of the general class of tryptophan-based compounds that originally functioned as antioxidants in earlier life forms before assuming more complex functions in multicellular organisms, including humans. Psilocybine is an alkaloid that is soluble in water, methanol and aqueous ethanol, but insoluble in organic solvents like chloroform and petroleum ether. Its pKa values are estimated to be 1.3 and 6.5 for the two successive phosphate OH groups and 10.4 for the dimethylamine nitrogen, so in general it exists as a zwitterionic structure. Psilocybine is rapidly dephosphorylated in the body to psilocin, which is a partial agonist for several serotonergic receptors.

Psyllium Husk

Psyllium is mainly used as a dietary fiber, which is not absorbed by the small intestine. As a thickener, it has been used in ice cream and frozen desserts. Psyllium mucilage is also used as a natural dietary fiber for animals. The dehusked seed that remains after the seed coat is milled off is rich in starch and fatty acids, and is used in India as chicken feed and as cattle feed.

Pukateine is an alkaloid found in the bark of the New Zealand tree Pukatea. An extract from pukatea is used in traditional Māori herbal medicine as an analgesic, and it is thought pukateine is the active component, as it is similar in both structure and activity to alkaloids such as glaucine and tetrahydropalmatine which are found in Chinese medicinal herbs used as analgesics.It has multiple mechanisms of action, with the most prominent effects being as an agonist at the D2 dopamine receptor and antagonist at the α1 adrenergic receptor.

Purmorphamine LAB GRADE 97%

Purmorphamine, under the IUPAC name  9-Cyclohexyl-N-[4-(4-morpholinyl)phenyl]-2-(1-naphthalenyloxy)-9H-purin-6-amine, is a cell-permeable 6,9-trisubstituted purine which directly binds and activates Smoothened (in HEK293T cell:IC50= ~ 1.5 μM ).So it  has been shown to activate the Hedgehog (Hh) signaling pathway which is important for regulating embryonic patterning, stem cell renewal, and tissue regeneration.

Pyrantel Pamoate

Pyrantel pamoate is used as a deworming agent in the treatment of hookworms and roundworms in domesticated animals such as horses, cattle, sheep, pigs, cats, dogs, and many other species. It is a combination of pyrantel and pamoic acid. Some drug companies pair pyrantel pamoate with praziquantel for tapeworms, and sometimes febantel for whipworms in order to provide more complete treatment for intestinal parasites in one dose.
