erythrophleum fordii/悪性腫瘍

Cytotoxic activity-guided fractionation of Erythrophleum fordii led to the isolation of two new cassaine diterpenoid-diterpenoid amide dimers, erythrophlesins H-I (1, 2). Spectral data indicated that they consist of asymmetrical dimeric structure via an ester bond between two cassaine diterpenoids.

Apoptosis pathways in cells are classified into two pathways: the extrinsic pathway, mediated by binding of the ligand to a death receptor and the intrinsic pathway, mediated by mitochondria. Apoptosis is regulated by various proteins such as Bcl-2 (B-cell lymphoma 2) family and cellular FLICE

A phytochemical investigation into the bark of Erythrophleum fordii yielded four new compounds, two new cassaine diterpenoids (erythrofordin T and U, 1 and 2) and two new cassaine diterpenoid amines (erythroformine A and B, 6 and 7), as well as nine known compounds. We report for the first time the

Angiogenesis is one of the hallmarks of cancer, playing an essential role in tumor growth, invasion, and metastasis. 3β-Acetyl-nor-erythrophlamide (3-ANE), a cassaine diterpene alkaloid compound from Erythrophleum fordii, exerts various pharmacological effects, including antitumor activity. However,

The incidence of lung cancer has increased while the mortality rate has continued to remain high. Effective treatment of this disease is the key to survival. Therefore, this study is a necessity in continuing research into new effective treatments. In this study we determined the effects of three

Erythrosides A-G, seven undescribed oleanane-type triterpenoid saponins, were isolated from the seeds of Erythrophleum fordii. Their structures with absolute configurations were determined by extensive spectroscopic analysis including one-dimensional [1D] and two-dimensional [2D] nuclear magnetic

Phytochemical investigation of the EtOH extract of the leaves of Erythrophleum fordii led to the isolation of two oleanane-type triterpene saponins (1-2) and five cassaine-type diterpenoids (4-8) along with one known methyl 3 β-hydroxy-erythrosuamate (3). Their structures were established by

A phytochemical investigation of the bark of Erythrophleum fordii led to six new cassaine diterpenoid amides (2, 4-8), together with two known compounds of the same skeleton, nor-cassamide ( 1) and nor-erythrosuamide (3). The structures were mainly established on the basis of 1D, 2D NMR and HR-MS

Two new cassaine-type diterpenoids, namely erythrofordins D (1) and E (2), sourced from a Cameroon collection of Erythrophleum suaveolens were isolated and assessed for anti-tumor activity. In the NCI-60 cancer cell assay, erythrofordins D (1) and E (2) were found to be cytotoxic in the low micro

Cassaine diterpenoids amides from the stem bark of Vietnamese Erythrophleum fordii Oliver were screened for their cytotoxic activity against human cancer cells. The cell proliferation assay results showed that, among the active compounds, 3β-acetyl-nor-erythrophlamide (3AEP) exhibited the

Six new cassaine diterpenoids (1, 3-7), along with three known ones (2, 8-9) were isolated from the seeds of Erythrophleum fordii. Their structures were elucidated by extensive spectroscopic methods and acid hydrolysis. Compound 2 was tested to be the most potent one and showed more sensitive

Detailed phytochemical investigation from the leaves of Erythrophleum fordii resulted in the isolation of 13 compounds, including three cassaine diterpenoid-diterpenoid amide dimers (1, 3 and 5), and seven cassaine diterpenoid amides (6 and 8-13), together with three previously reported ones,

Angiogenesis plays a critical role in embryonic development and various physiological processes. However, excessive angiogenesis is associated with several pathological conditions including cancer. Angiogenesis is closely related to tumor growth, invasion and metastasis, and is considered a prime

BACKGROUND Herbal plants are a preferred source of anticancer agents. This study aims to screen the anticancer activity of a crude extract of twigs of (a) Bombax anceps Pierre var. anceps (BA); (b) Catunaregam tomentosa (Blume ex DC.) Tirveng. (CT); (c) Erythrophleum succirubrum Gagnep. (ES); (d)

BACKGROUND Plants that are used as traditional medicine represent a relevant pool for selecting plant candidates that may have anticancer properties. In this study, the ethnomedicinal approach was used to select several medicinal plants native to Nigeria, on the basis of their local or traditional
