The invention provides a hapten derivatised with a crosslinker at the nitrogen of the 8null-carboxamide of 2-oxo-3-hydroxy LSD. The invention also provides an immunogen comprising the aforementioned hapten coupled to an antigenicity-conferring carrier material; a conjugate comprising the aforementioned hapten coupled to a labelling agent, as well as, antibodies raised against the aforementioned immunogen and capable of binding with at least the 3-hydroxy-2-pyrrolidone structural epitope of 2-oxo-3-hydroxy LSD.

There are disclosed intermediates to pharmaceutical compounds of the formula ##STR1## in which R.sup.1 is an aliphatic or aromatic function, and R.sup.2 and R.sup.3 are each hydrogen, C.sub.1-4 alkyl or a protecting group; and salts thereof.
摘要:
A therapeutic method employing 2,3-dihydroergolines is disclosed. Said method enhances serotonergic function in the nervous system of a mammal in need thereof, thereby finding application in serotonin-mediated physiological manifestations including memory, depression, anxiety, pain and appetite. Also disclosed are pharmaceutical compositions containing said 2,3-dihydroergolines in admixture with pharmaceutically acceptable diluents and carriers.
摘要:
Conjugates of SN-38 that provide optimal drug release rates and minimize the formation of the corresponding glucuronate are described. The conjugates release SN-38 from a polyethylene glycol through a β-elimination mechanism.
摘要:
The compounds of the following formula: wherein R, R2, R3 and A have the meanings given in the specification, are endowed with selective A3 adenosine receptor antagonist activity. These compounds can be used in a pharmaceutical composition to treat disorders caused by excessive activation of the A3 receptor, or can be used in a diagnostic application to determine the relative binding of other compounds to the A3 receptor. The compounds can be labeled, for example with fluorescent or radiolabels, and the labels used in vivo or in vitro to determine the presence of tumor cells which possess a high concentration of adenosine A3 receptors.
摘要:
Ergot alkaloids are isolated from ergot in high yields and purity by a process including extracting Claviceps purpurea, i.e., ergot, with a toluene/ethanol solvent mixture to obtain a primary extract. The primary extract can be further subjected to two steps of liquid-liquid extraction to purify the alkaloids resulting in a purified toluene extract. The toluene extract can be further partially evaporated and a crystalline product obtained by crystallization from the toluene or a mixture of toluene and an aliphatic hydrocarbon.
摘要:
A process for the long term modification and regulation of lipid and carbohydrate metabolism--generally to reduce obesity, insulin resistance, and hyperinsulinemia or hyperglycemia, or both (these are the hallmarks of noninsulin dependent, or Type II diabetes)--by administration (i.e., by oral, sublingual or parenternal administration) to a vertebrate, animal or human, of a dopamine agonist, e.g., bromocriptine. Administration of the bromocriptine is made over a limited period at a time of day dependent on the normal circadian rhythm of insulin resistant and insulin sensitive members of a similar species. Insulin resistance, and hyperinsulinemia and hyperglycemia, or both, can be controlled in humans on a long term basis by such treatment inasmuch as the short term, daily administration resets hormonal timing in the neural centers of the brain to produce long term effects.
摘要:
A therapeutic package for dispensing to, or for use in dispensing to, a vertebrate being treated for a metabolic condition selected from the group consisting of obesity, insulin resistance, hyperinsulinemia, and hyperglycemia comprising one or more unit doses of bromocriptine and labeling directing the use of the package in the treatment of the metabolic condition in a dosage regimen under which the delivery of the bromocriptine is confined to the period during the day near the time of day at which the serum prolactin concentration of a lean, insulin sensitive vertebrate of the same sex is low, and further directing the use of said package in conjunction with the concomitant administration to the vertebrate of one or more unit doses providing a therapeutically effective amount of a prolactin stimulator in a dosage regimen under which the delivery of the prolactin stimulator is confined to the period during the day after the time at which the serum prolactin concentration of a lean, insulin-sensitive vertebrate of the same sex reaches its lowest point and prior to the time of day when the prolactin concentration rises to a peak in lean, insulin-sensitive vertebrates of the same sex.
摘要:
A process for the long term modification and regulation of linid and glucose metabolism--generally to reduce obesity, insulin resistance, and hyperinsulinemia or hyperglycemia, or both (these being the hallmarks of noninsulin dependent, or Type II diabetes)--by administration to a vertebrate, animal or human, of a dopamine agonist and a prolactin stimulator. The dopamine agonist and prolactin stimulator are administered in daily dosages, respectively, at a time of day dependent on the normal circadian rhythm of fat and lean members of a similar species. Decreases in body fat deposits result by treatment of an obese species on a daily timed sequence based on circadian rhythms of the peak prolactin, or peak prolactin and peak glucocorticosteroid, blood level established for lean insulin sensitive members of a similar species. The dopamine agonist is administered at the time of, or just after the time of peak plasma prolactin concentration found in lean animals of the same species and the prolactin stimulator is administered at a time just before the plasma prolactin rhythm reaches its peak in lean animals. Insulin resistance, and hyperinsulinemia or hyperglycemia, or both, can also be controlled in humans on a long term basis by treatment corresponding to that of the treatment for obesity. The short term daily injections reset hormonal timing in the neural centers of the brain to produce long term effects.
