Cade was injecting rodents with urine extracts taken from manic patients in an attempt to isolate a metabolic compound which might be causing mental symptoms. Since uric acid in gout was known to be psychoactive, (adenosine receptors on neurons are stimulated by it; caffeine blocks them), Cade needed soluble urate for a control. He used lithium urate, already known to be the most soluble urate compound, and observed that it caused the rodents to become tranquil. Cade traced the effect to the lithium ion itself, and after ingesting lithium himself to ensure its safety in humans, he proposed lithium salts as tranquilizers. He soon succeeded in controlling mania in chronically hospitalized patients with them. This was one of the first successful applications of a drug to treat mental illness, and it opened the door for the development of medicines for other mental problems in the next decades.The rest of the world was slow to adopt this treatment, largely because of deaths which resulted from even relatively minor overdosing, including those reported from use of lithium chloride as a substitute for table salt. Largely through the research and other efforts of Denmarks Mogens Schou and Paul Baastrup in Europe, and Samuel Gershon and Baron Shopsin in the U.S., this resistance was slowly overcome.
Tioconazole is an antifungal medication of the imidazole class used to treat infections caused by a fungus or yeast. It is marketed under the brand names Trosyd and Gyno-Trosyd (Pfizer, now Johnson & Johnson). Tioconazole ointments serve to treat womens vaginal yeast infections. They are available in one day doses, as opposed to the 7-day treatments commonly used in the past. Tioconazole topical (skin) preparations are also available for ringworm, jock itch, athletes foot, and tinea versicolor or "sun fungus". It was patented in 1975 and approved for medical use in 1982. Side effects
Side effects of vaginal tioconazole may include temporary burning itching, or irritation of the vagina. Vaginal swelling or redness, difficulty or burning during urination, headache, abdominal pain, and upper respiratory tract infection have been reported by people using tioconazole. These side effects may be only temporary, and do not normally interfere with the patients comfort enough to outweigh the result. Synthesis
Antimycotic imidazole derivative. A displacement reaction between 1-(2,4-dichlorophenyl)-2-(1H-imidazol-1-yl)ethanol and 2-chloro-3-(chloromethyl)thiophene is performed. == References ==
