codeine (52-28-8, 76-57-3)  
Codeine Phosphate  ·  Isocodeine  ·  Ardinex
Isocodeine is an opioid research chemical related to codeine. It is an epimer of codeine that can be prepared from it by a Mitsunobu reaction. Dozens of derivatives and analogs of isocodeine and the related compound isomorphine have been produced.
morphine (64-31-3, 57-27-2)  
Morphia  ·  Morphine Sulfate  ·  MS Contin
Morphine is a pain medication of the opiate variety which is found naturally in a number of plants and animals. It acts directly on the central nervous system (CNS) to decrease the feeling of pain. It can be taken for both acute pain and chronic pain.
colchicine (64-86-8)  
Colchicine, (+-)-Isomer  ·  Colchicine, (R)-Isomer
Colchicine is a medication most commonly used to treat gout. It is a toxic natural product and secondary metabolite, originally extracted from plants of the genus Colchicum (autumn crocus, Colchicum autumnale, also known as "meadow saffron"). Adverse effects are primarily gastrointestinal upset at high doses.
L-tryptophan (153-94-6, 73-22-3)  
Tryptophan  ·  Optimax  ·  L Tryptophan
Tryptophan (abbreviated as Trp or W; encoded by the codon UGG) is an α-amino acid that is used in the biosynthesis of proteins. It contains an α-amino group, an α-carboxylic acid group, and a side chain indole, making it a non-polar aromatic amino acid. It is essential in humans, meaning the body cannot synthesize it: it must be obtained from the diet.
Ephedrine (134-72-5, 299-42-3)  
Ephedrine Sulfate  ·  Ephedrine Hydrochloride  ·  Ephedrine Renaudin
Ephedrine is a medication and stimulant. It is often used to prevent low blood pressure during spinal anesthesia. It has also been used for asthma, narcolepsy, and obesity but is not the preferred treatment.
PSEUDOEPHEDRINE (345-78-8, 90-82-4)  
Sudafed  ·  Pseudoephedrine Hydrochloride  ·  Pseudoephedrine HCl
Pseudoephedrine (; PSE) 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 in higher doses. The salts pseudoephedrine hydrochloride and pseudoephedrine sulfate are found in many over-the-counter preparations, either as a single ingredient or (more commonly) in combination with antihistamines, guaifenesin, dextromethorphan, and/or paracetamol (acetaminophen) or an NSAID (such as aspirin or ibuprofen).
Melatonin (8041-44-9, 73-31-4)  
Melatonin, also known as N-acetyl-5-methoxy tryptamine, is a hormone that is produced by the pineal gland in animals and regulates sleep and wakefulness. Melatonin is also produced in plants where it functions as a first line of defense against oxidative stress. In animals, melatonin is involved in the entrainment (synchronization) of the circadian rhythms including sleep-wake timing, blood pressure regulation, seasonal reproduction, and many others.
papaverine (61-25-6, 58-74-2)  
Papaverine Hydrochloride  ·  Pavabid  ·  Cerespan
Papaverine (Latin papaver, "poppy") is an opium alkaloid antispasmodic drug, used primarily in the treatment of visceral spasm, vasospasm (especially those involving the intestines, heart, or brain), and occasionally in the treatment of erectile dysfunction. It is used in the treatment of acute mesenteric ischemia. While it is found in the opium poppy, papaverine differs in both structure and pharmacological action from the analgesic (morphine-related) opium alkaloids (opiates).
ATROPINE (13269-35-7, 51-55-8, 101-31-5, 5908-99-6)  
Atropine Sulfate  ·  Atropine Sulfate Anhydrous  ·  Atropin Augenöl
Atropine is a medication to treat certain types of nerve agent and pesticide poisonings as well as some types of slow heart rate and to decrease saliva production during surgery. It is typically given intravenously or by injection into a muscle. Eye drops are also available which are used to treat uveitis and early amblyopia.
Hyoscine (51-34-3, 138-12-5)  
Scopolamine  ·  Scopolamine Hydrobromide  ·  Transderm Scop
phenylpropanolamine (36393-56-3, 48115-38-4, 14838-15-4, 37577-28-9)  
Phenylpropanolamine Hydrochloride  ·  Norephedrine  ·  Dexatrim
Phenylpropanolamine (PPA) is a sympathomimetic agent which is used as a decongestant and appetite suppressant. It is commonly used in prescription and over-the-counter cough and cold preparations. In veterinary medicine, it is used to control urinary incontinence in dogs.
(-)-Norephedrine (492-41-1, 14838-15-4, 700-65-2)  
Phenylpropanolamine  ·  Phenylpropanolamine Hydrochloride  ·  Norephedrine
(-)-NORPSEUDOEPHEDRINE (36393-56-3, 53643-20-2, 37577-07-4)  
L-Norpseudoephedrine, or (−)-norpseudoephedrine, is a psychostimulant drug of the amphetamine family. It is one of the four optical isomers of phenylpropanolamine, the other three being cathine ((+)-norpseudoephedrine), (−)-norephedrine, and (+)-norephedrine; as well as one of the two enantiomers of norpseudoephedrine (the other, of course, being cathine). Similarly to cathine, L-norpseudoephedrine acts as a releasing agent of norepinephrine (EC50 = 30 nM) and to a lesser extent of dopamine (EC50 = 294 nM).
Norephedrine (36393-56-3, 14838-15-4, 37577-28-9, 700-65-2)  
Phenylpropanolamine  ·  Phenylpropanolamine Hydrochloride  ·  Dexatrim
Phenylpropanolamine (PPA) is a sympathomimetic agent which is used as a decongestant and appetite suppressant. It is commonly used in prescription and over-the-counter cough and cold preparations. In veterinary medicine, it is used to control urinary incontinence in dogs.
scopolamine (51-34-3)  
Hyoscine  ·  Scopolamine Hydrobromide  ·  Transderm Scop
Cathinone (71031-15-7)  
Cathinone (also known as benzoylethanamine, or β-keto-amphetamine) is a monoamine alkaloid found in the shrub Catha edulis (khat) and is chemically similar to ephedrine, cathine, methcathinone and other amphetamines. It is probably the main contributor to the stimulant effect of Catha edulis. Cathinone differs from many other amphetamines in that it has a ketone functional group.
Oxymatrine (16837-52-8)  
Oxymatrine (matrine oxide, matrine N-oxide, matrine 1-oxide) is one of many quinolizidine alkaloid compounds extracted from the root of Sophora flavescens, a Chinese herb. It is very similar in structure to matrine, which has one less oxygen atom. Oxymatrine has a variety of effects in vitro and in animal models, including protection against apoptosis, tumor and fibrotic tissue development, and inflammation.
L-Hyoscyamine (51-55-8, 101-31-5, 5908-99-6)
