Therefore, electrophoresis of positively charged particles or molecules is sometimes called cataphoresis, while electrophoresis of negatively charged particles or molecules (anions) is sometimes called anaphoresis.
2,5-Dimethoxy-4-methylamphetamine (DOM), also known as STP (standing for "Serenity, Tranquility, and Peace" and/or other phrases), is a psychedelic drug of the phenethylamine, amphetamine, and DOx families.
2,5-Dimethoxy-4-ethylamphetamine (DOET) is a psychedelic drug of the phenethylamine, amphetamine, and DOx families. [8] [6] [3] [2] It is closely related to DOM and is a synthetic analogue of the naturally occurring phenethylamine psychedelic mescaline.
Amphetamine is a weak base with a pK a of 9.9; [20] consequently, when the pH is basic, more of the drug is in its lipid soluble free base form, and more is absorbed through the lipid-rich cell membranes of the gut epithelium. [20] [87] Conversely, an acidic pH means the drug is predominantly in a water-soluble cationic (salt) form, and less is ...
In general, until the synthesis of dihydromorphine (c. 1900), the dihydromorphinone class of opioids (1920s), and oxycodone (1916) and similar drugs, there were no other drugs in the same efficacy range as opium, morphine, and heroin, with synthetics still several years away (pethidine was invented in Germany in 1937) and opioid agonists among ...
In response to decreased tetrahydrofolate (THF), the cell begins to transcribe more DHF reductase, the enzyme that reduces DHF to THF. Because methotrexate is a competitive inhibitor of DHF reductase, increased concentrations of DHF reductase can overcome the drugs inhibition. Many new drugs are under development to reduce antifolate drug ...
