Although indirubin is known to exhibit anti-cancer and anti-inflammatory activities, very little is known about its mechanism of action. In this study, we investigated whether indirubin mediates its effects through interference with the NF-kappaB pathway. As examined by the DNA binding of NF-kappaB,
OBJECTIVE
Patients with advanced and metastasized medullary thyroid carcinoma are difficult to treat since tumor cells do not respond to chemotherapeutic treatment and external radiation. Direct induction of cell death is a new therapeutic approach to therapy-resistant tumor cells. In this study we
Indirubin is a Chinese medicine extracted from indigo and known to be effective for treating chronic myelogenous leukemia, neoplasia, and inflammatory disease. This study evaluated the in vivo anti-inflammatory activity of indirubin in a lipopolysaccharide- (LPS-) induced mouse mastitis model. The
Indirubins are natural occurring alkaloids extracted from indigo dye-containing plants. Indirubins could inhibit various kinases, and might be used to treat chronic myelocytic leukemia, cancer and neurodegenerative disorders. 7-bromoindirubin-3-oxime (7Bio), an indirubin derivative derived from
Indirubin is the active component of Dang gui Long hui Wan, a traditional Chinese herbal medicine used as therapy for chronic myelogenous leukemia (CML). In clinical studies, indirubin seldom caused major side-effects. However, the functional effect of indirubin on acute lymphoblastic leukemia (ALL)
BACKGROUND
Indirubin, isolated from Indigo naturalis (Apiaceae) is a purple 3,2- bisindole and a stable isomer of indigo. Although it is known to have anti-inflammatory activities, its mechanism of action has not been elucidated.
METHODS
Seven-week-old female BALB/c mice were sensitized with
Indirubin-3'-monoxime (IO) is a derivative of Indirubin, compound of a Chinese medicinal recipe used to treat various diseases including leukemia. In this study, we investigated to what extent IO inhibits the growth of normal human lymphocytes. We defined various experimental conditions of
Indirubin, an active ingredient of a traditional Chinese medicine prescription named Danggui Longhui Wan, has been reported to exhibit abroad anti-cancer and anti-inflammation activities. However, the effect of indirubin on ulcerative colitis (UC) has not been addressed. Here, we investigated the
Indirubin-3'-monoxime (I3M) exhibits anti-proliferative activity in various cancer cells; however, its anti-cancer mechanism remains incompletely elucidated. This study revealed that I3M promotes the expression of death receptor 5 (DR5) and tumor necrosis factor (TNF)-related apoptosis-inducing
Indirubin plays an important role in the treatment of many chronic diseases and exhibits strong anti-inflammatory activity. However, the molecular mode of action during mastitis prophylaxis remains poorly understood. In this study, a lipopolysaccharide (LPS)-induced mastitis mouse model showed that
The bis-indole indirubin is the active ingredient of the Traditional Chinese Medicine recipe Danggui Longhui Wan used against chronic myelocytic leukemia. We have previously shown that indirubins are potent inhibitors of cyclin-dependent kinases and glycogen synthase kinase-3. We here investigated
Indirubin, a traditional Chinese medicine, is currently used to treat certain autoimmune diseases such as primary immune thrombocytopenia (ITP) in clinics. However, the effects of indirubin on expression of related genes in peripheral blood mononuclear cells (PBMCs) from ITP patients have not been
Microglial cells play critical roles in the immune and inflammatory responses of the brain. Under pathological conditions, the activation of microglia helps to restore brain homeostasis. However, chronic microglial activation endangers neuronal survival through the release of various proinflammatory
This study examined the anti-tumor effects of AGM130, a novel indirubin-3'-oxime derivative in A549 human non-small cell lung cancer cells. AGM130 significantly inhibited the proliferation and arrested the cell cycle of G2/M phase. Induction of apoptosis was detected in AGM130-treated A549 cells.
Cells undergoing necrosis release endogenous danger signals that possess proinflammatory potential. In this study we show that mature IL-1beta and IL-18 are released by necrotic cells but not by apoptotic cells. We identify 7-bromoindirubin-3'-oxime, an indirubin oxime derivative that induces
