Alangium longiflorum Merr. Leaf Extract Induces Apoptosis in A549 Lung Cancer Cells with Minimal NFκB Transcriptional Activation

Numai utilizatorii înregistrați pot traduce articole

The chemotherapy drug doxorubicin (DOX) is effective in treating many types of cancers. However, due to its pro-inflammatory and cardiotoxic side effects, other remedies have also been explored as alternative treatments. The plant Alangium longiflorum was reported to contain cytotoxic activity

Oncostatic effects of Alangium vitiense extracts (ICIG-EORTC 1131, 1186 and 1207) on lymphoid murine tumors.

Numai utilizatorii înregistrați pot traduce articole

A total alkaloid and two purified alkaloid extracts of Alangium vitiense were found to be oncostatic for L1210 leukemia; the total alkaloid exerted a noticeable activity, and the purified extracts exerted a borderline activity. These two purified extracts are noticeably oncostatic for two other

[Oncostatic activity of extracts from Alangium vitiense on murine lymphoid neoplasms].

Numai utilizatorii înregistrați pot traduce articole

A total alkaloid and two purified alkaloid extracts of Alangium Vitiense were revealed by our experimental screening to be oncostatic on L1210 leukemia and two other lymphoid neoplasias in Mice. They are not active on myelomonocytoid leukemia WEHI3 nor on B16 melanoma.

Antiproliferative Alkaloids from Alangium longiflorum, an Endangered Tropical Plant Species.

Numai utilizatorii înregistrați pot traduce articole

Alangium longiflorum is currently in extinction crisis, which will likely severely hamper further phytochemical investigation of this plant species from new collections. A crude extract of leaves of A. longiflorum (N33539), collected for the U.S. National Cancer Institute in 1989, showed potent

Bioactive cardinane sesquiterpenes from the stems of Alangium salviifolium.

Numai utilizatorii înregistrați pot traduce articole

A dichloromethane extract of the stems of Alangium salviifolium afforded twelve cardinane sesquiterpenes, seven of which are new alangenes A-G (1-7) and five known compounds (8-12). Their structures were elucidated on the basis of spectroscopic techniques including UV, IR, and NMR spectroscopies,

Octahydro-Protoberberine and Protoemetine-Type Alkaloids from the Stems of Alangium salviifolium and Their Cytotoxicity.

Numai utilizatorii înregistrați pot traduce articole

Two octahydro-protoberberine alkaloids, alangiifoliumines A (1) and B (2), and two new protoemetine derivatives, alangiifoliumines C (3) and D (4), together with 11 known compounds, have been isolated from the stems of Alangium salviifolium. While the structures of

Inhibition of thymidylate synthase by pergularinine, tylophorinidine and deoxytubulosine.

Numai utilizatorii înregistrați pot traduce articole

The activity of thymidylate synthase (TS) purified in our laboratory from Lactobacillus leichmannii was inhibited by pergularinine (PGL) and tylophorinidine (TPD) and deoxytubulosine (DTB) isolated from the Indian medicinal plants Pergularia pallida and Alangium lamarckii respectively. Cytotoxicity

Dihydrofolate reductase and cell growth activity inhibition by the beta-carboline-benzoquinolizidine plant alkaloid deoxytubulosine from Alangium lamarckii: its potential as an antimicrobial and anticancer agent.

Numai utilizatorii înregistrați pot traduce articole

Beta-carboline-benzoquinolizidine plant alkaloid deoxytubulosine (DTB) was evaluated and assessed for the first time for its biochemical and biological activity employing the biomarker dihydrofolate reductase (DHFR) (5,6,7,8-tetrahydrofolate: NADP+ oxidoreductase, EC 1.5.1.3) as the probe enzyme, a

Sesquiterpenes and alkaloids from the roots of Alangium chinense.

Numai utilizatorii înregistrați pot traduce articole

Four new sesquiterpenes (1-4), four new alkaloids (5a, 6a, 6b, and 7), and nine known compounds (5b and 8-15) were isolated from an ethanolic extract of roots of Alangium chinense. The structure of 1 was confirmed by X-ray crystallography. The configurations of 5 and 6 were assigned by chiral HPLC

Salicin inhibits AGE-induced degradation of type II collagen and aggrecan in human SW1353 chondrocytes: therapeutic potential in osteoarthritis.

Numai utilizatorii înregistrați pot traduce articole

Osteoarthritis (OA) is a major age-related disease, which may be caused by the accumulation of advanced glycation end-products (AGEs). Excessive degradation of type II collagen and aggrecan by matrix metalloproteinases (MMPs) and a disintegrin and metalloproteinase with thrombospondin type 1 motif

Phenolic glycosides from Alangium salviifolium leaves with inhibitory activity on LPS-induced NO, PGE(2), and TNF-alpha production.

Numai utilizatorii înregistrați pot traduce articole

Three new phenolic glycosides, salviifosides A-C (13), and three known compounds salicin (4), kaempferol (5), and kaempferol 3-O-beta-d-glucopyranoside (6) were isolated from the leaves of Alangium salviifolium (L.f.) Wangerin (Alangiaceae). The structures of the new metabolites were determined on
