ursolic acid/necrosis

An anti-inflammatory triterpenoid, ursolic acid (UA), has recently been found unexpectedly to induce the release of a pro-inflammatory mediator in resting macrophages. In this study, we found that topical applications of UA to mouse skin twice a week for 2 weeks significantly enhanced mRNA

METHODS Ursolic acid, a natural pentacyclic triterpenic acid, possesses anticancer potential and diverse biological effects, but its correlation with glioblastoma multiforme cells and different modes of cell death is unclear. We studied the cellular actions of human glioblastoma multiforme

Ursolic acid (UA), a pentacyclic triterpene acid, is reported to have anti-tumor activities; however, the mechanism underlying its anti-tumorigenic effects is poorly understood. To further determine the mechanism of UA, we investigated the effects of UA on the release of nitric oxide (NO) and tumor

E-selectin is an early response adhesion molecule expressed on the surface of endothelial cells during inflammatory responses. We examined the effects of two pentacyclic triterpenoid acids, ursolic acid (UA) and oleanolic acid (OA), on the expression of E-selectin by cultured human umbilical vein

Pro-inflammatory cytokines, such as tumor necrosis factor (TNF)-α, induce the expression of a wide variety of genes, including intercellular adhesion molecule-1 (ICAM-1). Ursolic acid (3β-hydroxy-urs-12-en-28-oic acid) was identified to inhibit the cell-surface ICAM-1 expression induced by

OBJECTIVE Ursolic acid (UA), a natural pentacyclic triterpenoid acid, has been reported to show immunomodulatory activity. This study investigated the effects of UA on nuclear factor-kappa B (NF-κB) signaling in cells and experimental murine colitis. METHODS Human intestinal epithelial cells (IECs)

Prostate cancer is one of the most commonly occurring malignancies in men, and because existing treatments are not able to manage this neoplasm adequately, novel approaches are needed. Although tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) has strong antitumor activity via the

Over the past two decades, bioactive natural compounds have been shown to be a plausible adjunct to the treatment of breast cancer, the second leading cause of cancer death among American women. This study was designed to investigate the effects of ursolic acid (UA), a pentacyclic triterpene found

Human natural killer-1 (HNK-1) cell antigen is a glycan epitope involved in several neural events, such as neuritogenesis, myelination, synaptic plasticity and regeneration of the nervous system after injury. We have recently identified the small organic compound ursolic acid (UA) as a HNK-1 mimetic

Ursolic acid (UA), a common pentacyclic triterpenoid compound, has been reported to have many benefits and medicinal properties. However, its protective effects against carbon tetrachloride (CCl4) induced injury in kidneys are not yet clear. In the current report, we investigated whether UA

Cranberry, the fresh or dried ripe fruit of Vaccinium macrocarpon Ait. (Ericaceae), is currently used as adjunct therapy for the prevention and symptomatic treatment of urinary tract infections. Data from clinical trials suggest that extracts of cranberry or cranberry juice reduce the bacterial load

The objective of the study was to investigate the activity of ursolic acid (UA) on proinflammatory (Th1) and anti-inflammatory (Th2) cytokines in the peripheral blood of arthritic balb/c mice. Ursolic acid is ubiquitous in the plant kingdom and is a constituent of numerous plants which are having

OBJECTIVE Abdominal aortic aneurysms (AAA) is a chronic inflammatory disease in which signal transducer and activator of transcription 3 (STAT3), and disintegrin and metalloproteinase 17 (ADAM17) play important roles. However, it remains unclear whether ursolic acid (UA), a natural pentacyclic

Infectious hematopoietic necrosis virus (IHNV) is a fish viral pathogen that causes severe disease and huge economic losses in the salmonid aquaculture industry. However, anti-IHNV drugs currently are scarce. For the purpose of seeking out anti-IHNV drugs, the anti-IHNV activities of 32 medicinal

Ursolic acid (3-β-3-hydroxy-urs-12-ene-28-oic-acid; UA) is a triterpenoid carboxylic acid with various pharmaceutical properties. It is commonly found in apples, basil, berries, rosemary, peppermint, lavender, oregano, thyme, hawthorn and prunes. In the present study, the activities of UA against
