Clomifene (Clomid, Serophene, Milophene)
1970-01-01 00:59:59
what "fertility pills" are usually made ofused to treat female infertility due to anovulation (lack of ovulation)doesn't work if infertility is caused by the dude (defective or lack of spermies) or woman's infertility is caused by ovarian dysfunctioninhibits the negative feedback action of estrogen in the anterior pituitary gland, resulting in increased release of follicle-stimulating hormone (FSH) - this leads to a higher rate of ovulation and hence increased potential for pregnancycan actually cause multiple ovulation, increasing the risk of multiple birthssometimes four or five ova are released and fertilized - say hello to the local news crew, quintuplets!actually is a mixture of two geometric isomers, enclomifene and zuclomifeneused (abused?) by some male bodybuilders to block the estrogen-like effects (e.g. man titties!) produced by anabolic steroids and restore the body's natural production of testosterone (which is lost with steroid use)http://en.wikipedia.org/wiki/Clomiphen


Coprine
1970-01-01 00:59:59
a rare amino acid (derivative of glutamic acid) present in several edible species of mushroom belonging to the genus Coprinus ("inky caps") including the Common Inkcap (Coprinus atramentarius), a lawn mushroom that is, unexpectedly, fairly commonis thought that it or one of it's metabolites (cyclopropanone hydrate) inhibits the enzyme aldehyde dehydrogenase (ALDH)alcohol (ethanol) is primarily metabolized in the body by the enzyme alcohol dehydrogenase (ADH) into acetaldehyde, a fairly toxic substance responsible for many of the symptoms of a hangoveracetaldehyde is then further metabolized by ALDH into not nearly as toxic acetic acid, the stuff in vinegar that makes it taste and smell the way that it doesthe inhibition of ALDH results in the accumulation of acetaldehyde when alcohol is consumedgettin' smashed or even just having a single drink up to 72 hours after eating mushrooms containing coprine will cause acetaldehyde poisoning, symptoms of which include flushing of face and ne


Pulegone
1970-01-01 00:59:59
monoterpene present in essential oils from plants of the Lamiaceae (mint) familyparticularly high levels are found in the European (Mentha pulegium) and American (Hedeoma pulegioides) varieties of pennyroyalhas an odour similar to peppermint and camphorused as a flavouring agent, an ingredient in perfumes, and a flea repellentpennyroyal tea (and oil) is/was used in traditional folk medicine to promote menstruation and as an abortifacient to initiate self-abortionthere is a crappy Nirvana song about this (bring it, haters!)there is no scientific evidence available to support its efficacy in this regard (read: don't do this, it is a fantastically terrible idea!)ingestion of high doses of pennyroyal oil has been reported to cause organ toxicity - liver, central nervous system (convulsions), kidney, lung - and deathpulegone and one of its metabolites (menthofuran) are both bioactivated by liver enzymes to reactive oxidative intermediates that bind to cell proteins and cause liver damageAn


Galanthamine (Razadyne, Reminyl, Nivalin)
1970-01-01 00:59:59
reversible competitive inhibitor of acetylcholinesterase and allosteric modulator of nicotinic acetylcholinergic receptorsenhances brain function by increasing the amount of acetylcholine, a chemical substance required for the function of certain neural pathways, in the brainused to treat mild to moderate Alzheimer's diseasefound in several members of the Amaryllidaceae, a family of flowering plants that grow from bulbs and often produce nice-looking flowers (e.g. common snowdrop, one of the first flowers to bloom in the spring)originally used to treat poliomyelitis (polio), myasthenia gravis (a disease featuring progressive fatigue and muscle weakness), and muscular dystrophy in Eastern Europe during the Cold WarHeinrich M, Lee Teoh H.

Nitisinone (Orfadin)
1970-01-01 00:59:59
used to treat hereditary tyrosinaemia type 1 (HT-1), a rare genetic disease caused by a deficiency in fumarylacetoacetase (FAH), an enzyme involved in the metabolism of tyrosinetyrosine is my very favourite amino acid, since the body uses it to make a number of important biological molecules including thyroid hormones, melanin, and catecholaminestyrosine metabolism consists of a series of steps, with FAH being in charge of the last oneFAH deficiency causes the buildup of tyrosine metabolites produced by prior metabolic steps, several of which happen to be toxic to cellssince FAH is highly expressed in liver cells, HT-1 usually presents as liver failure or chronic liver diseasedoes its thing by inhibiting 4-hydroxyphenyl pyruvate dehydrogenase (HPPD), an enzyme with an annoyingly long name that is responsible for an early step in tyrosine metabolism (upstream of FAH), thus preventing toxic tyrosine metabolite productioninitially developed as a maize herbicide is a derivative of leptospe


Dehydroepiandrosterone (DHEA)
2007-03-02 21:28:00
steroid hormone made primarily by the adrenal gland that is also used as a drugthe adrenal gland can be thought of as a pair of triangular-shaped lemons (work with me, people) that sit on top of the kidneys - the rind (cortex) produces steroid hormones and the pulp (medulla) produces catecholamines (e.g. adrenaline)used by the body to make both androgens (e.g. testosterone) and estrogens (male and female sex hormones, respectively)cheating athletes, take note:in women, taking DHEA as a drug increases testosterone in women, leading to insulin resistance, acne, and masculinizing effects (kinda turns you into a dude - baldness, facial hair and increased body hair, lowering of voice, etc.)taking DHEA as a drug has not been shown to enhance gains in muscle size or strength produced with strength training alone and thus has little or no benefit for use in athleticsclassified as an anabolic steroid in 2004 in the US of A, making it a controlled substancepreviously was sold legally as a nutrit

Myristicin and Elemicin
2007-03-08 04:14:00
found in nutmeg and mace, two common spices that are produced from the seed and aril, respectively, of Myristica fragrans, a nice lookin' tree with green leaves that is native to tropical southeast Asia and Australasiaare responsible for the psychedelic action of these spicesabout 1-2 teaspoons of spice can really mess you up: euphoria, visual hallucinations, psychosis, and feelings of impending doom and unreality PLUS impressively potent nausea, vomiting, and tremors (and lots of other stuff)nutmeg was at one point used therapeutically at doses of nine teaspoonfuls daily to control diarrhea associated with thyroid cancermakes sense since both compounds structurally resemble mescalineapparently myristicin is a moderately effective antibacterial agent, which would potentially make it a useful natural preservativeNarasimhan B, Dhake AS.

Flunitrazepam (Rohypnol, roofies)
2007-03-12 22:38:00
fast-acting and powerful sedative/hypnotic drug used primarily to treat insomnia and settle people down prior to giving them general anaesthesiais a benzodiazepine, meaning that it acts on GABA-A receptors, which are prevalent throughout the brain, to enhance the flow of chloride ions into neurons, resulting in a generalized depression of neural activity that results in sedation (feeling dopey) progressing to hypnosis (sleep)is about 7-10 times more potent than diazepam (Valium), the archetypal benzodiazepineall benzos also work as anxiolytic and anticonvulsant agents, as well as skeletal muscle relaxantswidely used recreationally to enhance the effects of alcohol and other drugs, although some people get high off of it alone (mechanism is unknown) or use it as a 'downer' to deal with the side effects of stimulants ('uppers')has been used as a date rape drug and to facilitate robberies (it causes anterograde amnesia in addition to sedation, so the victim often remembers nothing) an


Gadolinium

a malleable and ductile rare earth metal named after Johan Gadolin, a Finnish scientist who discovered the best named element of all time, yttriumapparently discovering one element means you get another one named after you, what the deal?is strongly magnetic at room temperature and demonstrates a magnetocaloric effect (which means, of course, magnetic refrigerators!)motexafin gadolinium is a novel anticancer agent that enhances the ability of radiation therapy to kill cancer cellsconsists of a gadolinium cation contained in the centre of a large heterocyclic organic ring, much like a porphyrin ringseveral mechanisms of action, including acting selectively on cancer cells to deplete their stores of metabolites that they need to repair the oxidative damage caused by irradiationis currently being studied for use alone or in conjunction with radiation therapy in a number of different cancers, including those of the brain, lungs, kidneys, and pancreassolutions of organic gadolinium complexe


Benzylpiperazine (BZP)
2007-03-12 23:13:00
methamphetamine-like stimulant that has recently been the subject of much investigation in New Zealand (where it is legal and used as a party drug)effects include euphoria, enhanced sensory perception (whoa, this glo stick won't stop blinking out coded messages and this trance music tastes like the ocean!), hyperactivity, and stereotypy (constant repetition of certain meaningless gestures or movements, often seen in schizophrenics)repeated use leads to sensitization (less drug required to produce same effect) and cross-sensitization to crystal meth in ratsless potent and probably less addictive than crystal meth (but potentially addictive nonetheless!)several contributing mechanisms of action, with the net result being the enhancement of the effects of serotonin, dopamine, and norepinephrine (all monoamine neurotransmitters) in the brainwas originally designed in a lab to be an anthelmintic (works against parasitic worms) agent, to be used to expel wormies (particularly roundworms and


Itchy, itchy, itchy: Antifungals and the treatment of yeast infections
2007-03-16 03:15:00
Being a dude, I thank my lucky stars on a daily basis that I am not prone to fungus-type infestations of my nether regions. Let's hear it for external genitalia! A woman's special area, like many other parts of the human body, is inhabited by both bacteria and fungi. These microbes are usually just chilling out, growing slowly and not bringing any attention to themselves. A yeast infection occurs when Candida albicans, a yeast (which is a type of fungus), is given the opportunity to take over downstairs due to a change in the local environment, which can be caused by a number of things including antibiotics, pregnancy, and a weakened immune system. Candida sets up shop in the most holy of holies, and before you know it, you've got vaginal candidiasis (a yeast infection)! And just so you know, I plan to see how long I can go in this post without mentioning the actual anatomical terms for 'womanly bits'. I consider this to be an exercise in puritan restraint. And euphemisms are fun!

Podophyllotoxin (Podofilox)
2007-03-21 22:08:00
non-alkaloid lignan toxin present in podophyllin, resin produced by the rhizomes of plants belonging to the genus Podophyllum, for which it and the aforementioned resin are named, as well as a number of other genera that I don't feel like listing since I'm pretty sure most of you don't care that much and I really, really want to avoiding bogging down my posts with boring information and hideously long-winded sentencesplants containing lignans are commonly found in traditional medicine, making them interesting starting points for the development of new drugsthe genus Podophyllum includes Podophyllum peltatum (American Mayapple), a perennial herb native to eastern North America that grows in coloniesis used as a topic antiviral agent in the treatment of condyloma acuminatum (genital warts!) caused by human papilloma virus as well as other types of warts found on one's naughty bitshas also been used in the treatment of psoriasis vulgaris and rheumatoid arthritiskills cancer cells but

α-Latrotoxin
2006-12-18 21:18:00
neurotoxic (bad fer teh brain) protein present in the venom of widow spiders (members of the genus Latrodectus) including the infamous black widowone of seven latrotoxins, is the only one that is vertebrae-specific (only affects animals with a spine, so my chemistry prof should be safe! OH SNAP!), the others being primarily active against insects (the natural prey of the spiders) or crustaceansthe current theory is that four units of the protein can join together to form pores in cells, with the resulting changes in ion flux signalling the release of neurotransmitters from nerve cells, producing (among other things) muscle contraction, manifested as painful abdominal cramps and breathing difficultieshttp://en.wikipedia.org/wiki/Latrotoxinhttp://en.wikipedia.org/wiki/Latrodectism


(Ergoline derivatives)
2006-11-29 16:52:00
Okay, so we've all heard of LSD, right? Acid trips, Timothy Leary, "Tomorrow Never Knows", dirty hippies, "I am a golden god", etc. Fact is, LSD is but one of an impressively large number of derivatives of a compound called ergoline. These derivatives can be found in ergot (parasitic fungus that grows on grains and grasses), Hawaiian baby woodrose (climbing vine native to the Indian subcontinent but apparently also grown in Hawaii), and several species of morning glory (flowing plant that blooms in the morning). In addition to their use/abuse as psychedelic drugs, many natural and synthetic derivatives of ergoline have more legitimate applications:ergonovine and methylergonovine (Methergine, Methylergometrine) - directly stimulate contractions of uterine smooth muscle (oxytocic) - have historically been used to induce labour, but are now only used to prevent and treat postpartum and postabortion hemorrhage (uncontrolled bleeding occurring after birth or abortion) - contraction of the


Strychnine

Sucralfate (Carafate)
2007-04-02 19:57:00
In the drug blog business, it can get awfully tempting to just paraphrase Wikipedia articles all the time. I've done it on occasion, I will shamefully admit, but I usually try and get actual research articles as sources for my posts. And when I do succumb to my more basic urges (greed and laziness, if you must know) and 'rip off' the Wik, I just pick out a few choice tidbits, change 'em 'round and explain things differently so it isn't plagiarism, and then add some amusing little comments. It's not like I'm cutting and pasting. Anyway, I just had a lecture on gastrointestinal drugs, being a pharmacology student and all, and I thought this one in particular was pretty neat. Sucralfate is a sucrose sulfate-aluminum complex (a sugar with a bunch of metal salts attached to it) that is used to treat peptic ulcers, particularly those that arise in the duodenum, as well as gastroesophageal reflux disease (GERD). Peptic ulcers are essentially holes burned through the lining of th
