    摘要: 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.

    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.
