Pancratistatin derivatives, 1-O-(3-hydroxybutyryl)pancratistatin (HBP) and 1-O-(3-O-beta-D-glucopyranosylbutyryl)pancratistatin (GBP), showed strong cytostatic activity against rat embryo fibroblast 3Y1 at concentrations less than 1 microM. When the effect on cell cycle progression was examined in 3Y1 fibroblasts arrested at G0/G1 phase by serum deprivation, HBP, GBP, and pancratistatin inhibit...

Aedes albopictus (Skuse) is a widespread mosquito, vector of important human arboviruses, including Chikungunya, Dengue and Zika. It an extremely difficult species to control even for the onset resistances chemicals insecticides, therefore ecofriendly products are urgently needed. In this study, activity Amaryllidaceae alkaloids some their semisynthetic derivatives, 2-methoxy-1,4-naphthoquinone...

Amaryllidaceae is a monocot plant family represented in the world with approximately 85 genera and 1100 species, which has great economic value as an ornamental plant, well plants that are widely used treatment [1,2]. Narcissus L. member of family, perennial, herbaceous bulbs bear fragrant flowers up to 30 different species grow naturally Western Europe, Mediterranean Region, China Japan [3,4]....

Objective: The present study on garlic cloves (Allium sativum) belongs to family Amaryllidaceae has been focused. This is a natural medicinal plant used for disease preventions against all kinds of internal infections. Preliminary screening of phytochemicals has found plenty of secondary metabolites which are present in garlic cloves. Their functional groups and mineral compositions, the potent...

Calprotectin, a complex of two calcium-binding proteins that belong to the S100 protein family, is abundant in the cytosolic fraction of neutrophils. A high level of calprotectin reportedly exists in extracellular fluid during various inflammatory conditions, such as rheumatoid arthritis, cystic fibrosis and abscesses. However, the exact biological role(s) of the factor is now under investigati...

Zephycandidine A (1), the first naturally occurring imidazo[1,2-f]phenanthridine alkaloid, was isolated from Zephyranthes candida (Amaryllidaceae). The structure of 1 was elucidated by spectroscopic analyses and NMR calculation, and a plausible biogenetic pathway for zephycandidine A (1) was proposed. Zephycandidine A (1) exhibited significant cytotoxicity against five cancer cell lines with IC...
