A new alkaloid, belonging to the pretazettine group of Amaryllidaceae alkaloids, was isolated from dried bulbs of Narcissus jonquilla quail and named jonquailine. Its structure, including the absolute configuration, was elucidated using various NMR, ECD and ESI MS techniques. Initial biological
We reported previously that pretazettine hydrochloride (PTZ), a narcissus alkaloid, was found to be active against intraperitoneally implanted Lewis lung carcinoma. The therapeutic effectiveness of PTZ has now been investigated on the subcutaneously implanted Lewis lung carcinoma (LLC) which is a
Four undescribed alkaloids have been isolated from the bulbs of the previously unstudied Crinum scillifolium. These compounds were targeted following a state-of-the-art molecular networking strategy comprising a dereplication against in silico databases and re-ranking of the candidate structures
Amaryllidaceae plants are known to be a great source of alkaloids, which are considered an extensive group of compounds encompassing a wide range of biological activities. The remarkable cytotoxic activities observed in most of the Amaryllidaceae alkaloids derivatives have prompt the
Jonquailine, a new alkaloid recently isolated from Narcissus jonquilla quail, an Amaryllidaceae species cultivated for its flowers fragrance in Europe and USA, shows very significant anti-proliferative activity against several malignant cancer cell types. Although it was reported that this activity
