withanolide d/悪性腫瘍

Along with surgery and chemotherapy, radiation therapy (RT) is an important modality in cancer treatment, and the development of radiosensitizers is a current key challenge in radiobiology to maximize RT efficiency. In this study, the radiosensitizing effect of a natural compound from the

In spite of recent therapeutic advances, multiple myeloma (MM) remains a malignancy with very low curability. This has been partly attributed to the existence of a drug-resistant subpopulation known as cancer stem cells (CSCs). MM-CSCs are equipped with the necessary tools that render them highly

The goal of cancer chemotherapy to induce multi-directional apoptosis as targeting a single pathway is unable to decrease all the downstream effect arises from crosstalk. Present study reports that Withanolide D (WithaD), a steroidal lactone isolated from Withania somnifera, induced cellular

The Withanolide D is a chemotherapeutic potential against the human tumor cell. However, there is no report on the effect of this compound on ovarian function, especially on preantral folliculogenesis. The aim of this study was to evaluate the toxicity of a new candidate to anticancer drug,

Tumor-associated macrophages (TAM) are prominent components of tumor microenvironment (TME) and capable of promoting cancer progression. However, the mechanisms for the formation of M2-like TAMs remain enigmatic. Here, we show that lactate is a pivotal oncometabolite in the TME that drives

A new withanolide identified by spectroscopic analysis as 12beta-acetoxy-4-deoxy-5,6-deoxy-Delta(5)-withanolide D and Withanolide D, were isolated from the leaves of Acnistus arborescens. Cytotoxic activity of these two compounds against human tumor cell lines HT-29, MCF-7, MKN-45, HEp-2, HeLa,

Withania somnifera, a plant with known immunopotentiating activity and its bioactive fraction-Withanolide D were studied for their anti-metastatic activity using B16F-10 melanoma cells in C57BL/6 mice. Simultaneous administration of Withania extract (122 +/- 10 tumour nodules) and Withanolide (126

OBJECTIVE To characterize the angiogenic and inflammatory responses of human choroidal endothelial cells (HCECs) to stimulators and inhibitors of the ubiquitin proteasome pathway (UPP). METHODS The regulation of the UPP by the inhibitor withaferin A and its congener, withanolide D, two natural

Withania somnifera is an important medicinal herb that has been widely used for the treatment of different clinical conditions. The overall medicinal properties of Withania somnifera make it a viable therapeutic agent for addressing anxiety, cancer, microbial infection, immunomodulation, and

Seven withanolides, including four previously unknown, were isolated from the acetone and ethanol extracts of cultivated specimens of Acnistus arborescens. These four compounds were identified as rel-(18R,22R)-5β,6β:18β,20-diepoxy-3β,18α-dimethoxy-4β-hydroxy-1-oxowith-24-enolide,

β-catenin plays a pivotal role in organogenesis and oncogenesis. Alterations in β-catenin expression are common in pancreatic cancer, which is an extremely aggressive malignancy with a notably poor prognosis. In this report, we analyzed the apoptotic activity of withanolide-D (witha-D), a steroidal

From the leaves of Withania somnifera L. Dunal, a new withasteroid named as 5,6-de-epoxy-5-en-7-one-17-hydroxy withaferin A (6) was isolated along with several known compounds, namely 16β-acetoxy-6α,7α-epoxy-5α-hydroxy-1-oxowitha-2,17(20),24-trienolide (1), withanone (2), 16-en-27-deoxy withaferin A
