A selective inhibitor of peptidyl transferase center (PTC).
A selective inhibitor of peptidyl transferase center (PTC). In HL-60 (leukemia) cells, lycorine arrests the cell cycle at G2/M and induces apoptosis by a caspase-mediated pathway.

The alkaloid patterns in Leucojum aestivum L. shoot culture cultivated at temporary immersion conditions were investigated using gas chromatography-mass spectrometry. 18 alkaloids were identified, and galanthamine, hamayne and lycorine were dominant. The L. aestivum 80 shoot culture, cultivated at temporary

As a natural alkaloid extracted from Amaryllidaceae, lycorine shows various biological effects on tumor cells. Here we show that lycorine dose-dependently inhibited the LPS-induced up-regulation of nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) protein level in RAW264.7 cells. Besides, it

The members of the family Flaviviridae, including West Nile virus, yellow fever virus and dengue virus, are important human pathogens that are expanding their impact around the globe. The four serotypes of dengue infect 50-100 million people each year, yet

Plants of the Amaryllidaceae family have been used as therapeutic agents against CNS related maladies such as Alzheimer's disease. The known primary alkaloid constituents have significant biological activity. We identified the Lycoris alkaloids lycorine and lycoricidinol from Amaryllidaceae using a
A concise and stereoselective construction of the tetracyclic core of lycorine-type alkaloids and the formal synthesis of α-lycorane has been achieved. The feature of the current method is the employment of a bifunctional thiourea-catalyzed cascade reaction as a powerful tool
