Discovering how to regulate mitochondrial function to reduce cancer growth holds great potential for future cancer therapy development. Here we explore the effects of cryptotanshinone (CPT), a natural product derived from Salvia miltiorrhiza, on mitochondria of osteosarcoma (OS) both A rapid, sensitive and selective liquid chromatography-tandem mass spectrometric (LC-MS/MS) method for the simultaneous determination of tanshinone I, dihydrotanshinone I, tanshinone IIA and cryptotanshinone, the active components of Salvia miltiorrhiza in rat plasma, was developed. After
Effect of N(6)-benzyladenine (BA) on tanshinone formation in callus cultures of Salvia miltiorrhiza was examined in an attempt to increase the productivity of the medicinal compound, cryptotanshinone. Primary callus was induced by culturing leaf explants on Murashige and Skoog's (MS) basal medium
Matrix metalloproteinases (MMP-9 and MMP-2) production and smooth muscle cell (SMC) migration may play key roles in the phathogenesis of neointima formation and atherosclerosis. Especially inducible MMP-9 expression was directly involved in the cancer cell invasion and SMC migration through vascular
The amyloid precursor protein (APP) is cleaved enzymatically by non-amyloidogenic and amyloidogenic pathways. alpha-Secretase cleaves APP within beta-amyloid protein (Abeta) sequence, resulting in the release of a secreted fragment of APP (sAPPalpha) and precluding Abeta generation. Cryptotanshinone
Cryptotanshinone (CTS), a major constituent from the roots of Salvia miltiorrhiza (Danshen), is widely used in the treatment of coronary heart disease, stroke and less commonly Alzheimer's disease. Our recent study indicates that CTS is a substrate for P-glycoprotein (PgP/MDR1/ABCB1). This study has
Salvia miltiorrhiza is one of the most commonly used traditional Chinese medicine in treatment of cardiovascular and cerebrovascular diseases. Cryptotanshinone (CTS), tanshinone IIA (Tan IIA), dihydrotanshinone I (diTan I), and tanshinone I (Tan I) are the main active compounds in the liposoluble
Cryptotanshinone from Salvia miltiorrhiza Bunge was investigated for hepatoprotective effects in d-galactosamine (GalN)/lipopolysaccharide (LPS)-induced fulminant hepatic failure. Cryptotanshinone (20 or 40 mg/kg) was orally administered 12 and 1h prior to GalN (700 mg/kg)/LPS (10 μg/kg) injection.
Cyclooxygenase-2 (COX-2) is a key enzyme that catalyzes the biosynthesis of prostaglandins from arachidonic acid and plays a critical role in some pathologies including inflammation, neurodegenerative diseases and cancer. Cryptotanshinone is a major constituent of tanshinones, which are extracted
Cryptotanshinone, a well-known diterpene quinone from a widely used traditional Chinese herb named Salvia miltiorrhiza, has been reported for its therapeutical potentials on diverse activities. In this study, pharmacological effects of cryptotanshinone on acute lymphoblastic leukemia cells were
Cryptotanshinone (CTT), extracted from the root of Salvia miltiorrhiza Bunge (Danshen), exhibits activities against a variety of human cancers in vitro and in vivo. The purpose of this study was to investigate the potential inhibitory effect of CTT on bladder cancer. In this
Cryptotanshinone (CPT), a natural compound isolated from the plant Salvia miltiorrhiza Bunge, is a potential anticancer agent. However, little is known about its anticancer mechanism. Here, we show that CPT inhibited cancer cell proliferation by arresting cells in G(1)-G(0) phase of the cell cycle.
AMP-activated protein kinase (AMPK) performs a pivotal function in energy homeostasis via the monitoring of intracellular energy status. Once activated under the various metabolic stress conditions, AMPK regulates a multitude of metabolic pathways to balance cellular energy. In addition, AMPK also
The root of Salvia miltiorrhiza (Salviae miltiorrhizae radix), a herbal medicine has widely been used for the treatment of pain, miscarriage and oedema. In this study, we evaluated the neuroprotective effect of cryptotanshinone (CRT) from Salviae miltiorrhizae radix on sodium-nitroprusside
Malignant gliomas (MGs) are among the most aggressive types of cancers in the human brain. Frequent tumor recurrence caused by a lack of effective therapeutic approaches results in a poor prognosis. Signal transducer and activator of transcription 3 (STAT3), an oncogenic protein, is constitutively
