The synthesis, pharmacological evaluation, and structure-activity relationships of a new class of bronchodilator agents, derivatives of pyrazino[2,3-c][1,2,6]thiadiazine 2,2-dioxides are described. The compounds were prepared by reaction of 3,4,5-triamino-1,2, 6-thiadiazine 1,1-dioxide with suitable 1,2-dicarbonyl compounds or alpha-hydroxyiminoketones and subsequent N-alkylation. A transamination
描述了一种新型的支气管扩张剂吡唑并[2,3-c] [1,2,6]噻二嗪2,2-二氧化物的合成,药理评价和构效关系。通过使3,4,5-三氨基-1,2-噻二嗪1,1-二氧化物与合适的1,2-二羰基化合物或α-羟基亚氨基酮反应,然后进行N-烷基化反应来制备化合物。首次报道了用于合成在4-氨基具有不同取代基的衍生物的氨基转移过程。在体外筛选吡嗪并[2,3-c] [1,2,6]噻二嗪衍生物的气管舒张活性,并与茶碱相比将豚鼠体内的活性化合物作为支气管扩张剂进行评估。在研究的化合物中,最有趣的特性是4-氨基-1-乙基-6-甲基衍生物(21)。还报道了该衍生物的毒理学评价。
