We recently demonstrated that calprotectin, an abundant calcium-binding protein complex in polymorphonuclear leukocytes (PMNs), has the capacity to induce growth inhibition and apoptotic cell death against a variety of tumor cell lines and normal cells such as fibroblasts. Therefore, calprotectin
BACKGROUND
Multidrug resistance (MDR) is a major hurdle for cancer treatment worldwide and accounts for chemotherapy failure in over 90% of patients with metastatic cancer. Evidence of the cytotoxicity of Cameroonian plants against cancer cell lines including MDR phenotypes is been intensively and
Plants of the genus Crinum (Amaryllidaceae) are widely used in folk medicine in different tropical and subtropical regions around the world. The Indian species Crinum latifolium (L.) was traditionally used to treat rheumatism, fistula, tumors, earaches, rubefacient, tubercle and whitlow. In
BACKGROUND
Crinum latifolium L. (CL) leaf extracts have been traditionally used in Vietnam and are now used all over the world for the treatment of prostate cancer. However, the precise cellular mechanisms of the action of CL extracts remain unclear.
OBJECTIVE
To examine the effects of CL samples on
Medicinal plants have been considered as promising sources of drugs in treating various cancers. Crinum amabile (C. amabile), a plant species from the Amaryllidaceae family, is claimed to be a potential source for cancer chemotherapeutic compounds. Here, we aimed to investigate the potential
In this study, an efficient polysaccharide, named CAL-n (Crinum asiaticum L.-n) was isolated and purified from Crinum asiaticum L for the first time, Mw(molecular weight) of 730,000 Da. CAL-n comprised Rha(rhamnose), Sor(sorbose), Gal(galactose) and Glu(glucosein) the
A phytochemical investigation of the bulbs of Crinum asiaticum L. var. sinicum Baker resulted in the isolation of two new alkaloids, asiaticumines A and B (1 and 2, resp.), together with 21 known compounds, including nine alkaloids, four amides, five phenolic compounds, and three flavonoids. All 23
The present study investigated the anti-proliferative and chemosensitizing effects of Crinum asiaticum var. japonicum against multi-drug resistant (MDR) cancer cells. The 80% methanol extract, chloroform (CHCI3) fraction and butanol (BuOH) fraction of C asiaticum
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
Crinum zeylanicum is used in folk medicine as a rubefacient in rheumatism, a treatment for malaria or as a poison. Complex alkaloid profiles in C. zeylanicum plant organs were revealed by GC-MS analysis, including several bioactive compounds. Crinine, lycorine, 11-O-acetoxyambelline, ambelline,
Six compounds (1-6) were isolated from the methanol extract of Crinum latifolium by bioassay-guided separation. Among the six isolates, compounds 2 and 6 were new metabolites. Their structures were established as 4-senecioyloxymethyl-3,4-dimethoxycoumarin (2) and
Four novel and potently bioactive Amaryllidaceae alkaloids, 4,8-dimethoxy-cripowellin C (1), 4,8-dimethoxy-cripowellin D (2), 9-methoxy-cripowellin B (3), and 4-methoxy-8-hydroxy-cripowellin B (4), together with one known alkaloid, cripowellin C (5) were isolated from the 95% EtOH extract of the
BACKGROUND
Hippadine is an alkaloid isolated from Crinum macowanii. Crinum macowanii is used in South Africa to treat oedema, 'heart disease', rheumatic fever, cancer and skin diseases, and belongs to the plant family Amaryllidaceae, assumed to have originated in the South African region. The aim of
BACKGROUND
The traditional use of Amaryllidaceae plants to treat many disease have been known for a very long period of time. The chemical analysis of these plants has yielded a diversity of alkaloids with analgesic, anticholinergic, antitumor and antiviral activities. Crinum bulbispermum (Burm.f.)
The inhibition of the hedgehog (Hh) signaling pathway has emerged as an attractive anti-cancer strategy. As part of our continuing search for natural inhibitors of the Hh/GLI1 signaling pathway, we isolated three alkaloids (1-3) from Crinum asiaticum. Compounds 1 and 3 showed potent Hh/GLI1-mediated
