the problem of resistance constantly evolving to the drugs currently in use. For alkaloids, the acid-base dissociation constant, pK(a), is an important characteristic, thought to be associated with biological activity. In this contribution, pK(a) values for several indoloquinoline alkaloids were determined by using (1)H NMR spectroscopy in a mixture of solvents. The data were recalculated for water solutions
疟疾是全球最严重的健康问题之一。从天然来源中分离具有潜在抗疟活性的新治疗剂或半合成或合成制备此类治疗剂是解决对目前使用的药物不断发展的耐药性问题的一种策略。对于生物碱,酸碱解离常数pK(a)是重要的特征,被认为与生物活性有关。在此贡献中,通过在溶剂混合物中使用(1)H NMR光谱确定了几种吲哚喹啉生物碱的pK(a)值。使用先前报告的校正因子对水溶液的数据进行了重新计算。隐氯平及其异构体新隐油平的pK(a)值的结构依赖性,
