Oestrogen receptor (ER) is expressed in approximately 60%-70% of human breast cancer. Clinical trials and retrospective analyses have shown that ER-positive (ER+) tumours are more tolerant to chemotherapeutic drug resistance than ER-negative (ER-) tumours. In addition, isobavachalcone (IBC) is known
Prostate carcinoma causes a great number of deaths every year; therefore, there is an urgent need to find new drug candidates to treat advanced prostate cancer. Isobavachalcone (IBC) is the chalcone composition of Psoralea corylifolia Linn used in traditional Chinese medicine. Although IBC
BACKGROUND
Cancer remains an aggressive deadly disease, if drug resistance develops. This problem is aggravated by the fact that multiple rather than single mechanisms are involved in resistance and that multidrug resistance (MDR) phenomena cause inefficacy of many clinical established anticancer
Background: Colorectal cancer (CRC) is a common form of cancer associated with a high mortality rate and poor prognosis. Given the limited efficacy of current therapies for CRC, interest in novel therapeutic agents isolated from natural sources has increased. We studied the anticancer
Non-apoptotic cell-death induction is a potential strategy for cancer treatment. Cytoplasmic vacuolation-associated cell death represents a novel type of non-apoptotic cell-death. Here, we showed that isobavachalcone (IBC), a naturally occurring chalcone compound, selectively induced cell death with
Three new chalcones, xanthoangelol I (1), xanthoangelol J (2), and deoxydihydroxanthoangelol H (3), were isolated from an ethyl acetate-soluble fraction of exudates of the stems of Angelica keiskei, and their structures were established on the basis of spectroscopic methods. Nine aromatic compounds
Isobavachalcone (2',4',4-trihydroxy-3'-[3'-methylbut-3'-ethyl] chalcone or IBC) exhibits anticancer activities in a number of types of cancer cell. However, its role in tongue squamous cell carcinoma (TSCC) cells remains unclear. The aim of the present study was to investigate the biological effect
Despite recent advancements in therapeutic drugs, multiple myeloma remains an incurable disease. Therefore, a more effective treatment is urgently required. In this study, we show that isobavachalcone (IBC), a natural chalcone compound, induces apoptosis- and autophagy-related cell death in myeloma
Skeletal muscle atrophy is a condition characterized by damaged muscle fibers and reduced numbers of muscle cells due to various causes. Muscle atrophy is associated with chronic diseases, such as heart failure, diabetes, and aging-related diseases. Isobavachalcone (IBC) is a flavonoid found in
Four natural chalcones bearing prenyl or geranyl groups, i.e., bavachalcone (1a), xanthoangelol (1b), isobavachalcone (1c), and isoxanthoangelol (1d) were synthesized by using a regio-selective iodination and the Suzuki coupling reaction as key steps. The first total synthesis of isoxanthoangelol
Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) induces apoptosis in cancer cells without toxicity to normal cells. TRAIL binds to death receptors, TRAIL-R1 (DR4) and TRAIL-R2 (DR5) expressed on cancer cell surface and activates apoptotic pathways. Endogenous TRAIL plays an important
Chalcones exhibit chemopreventive and antitumor effects. Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is a naturally occurring anticancer agent that induces apoptosis in cancer cells and is not toxic to normal cells. We examined the cytotoxic and apoptotic effect of five chalcones
The investigation on the leaves of Morus alba L. was carried out to find the relationship of the constituents and the pharmacological activities. The isolation and purification were performed by various chromatographies such as silica gel, Sephadex LH-20, RP-C18 column chromatography and so on.
Acute myeloid leukemia is a disorder characterized by abnormal differentiation of myeloid cells and a clonal proliferation derived from primitive hematopoietic stem cells. Interventions that overcome myeloid differentiation have been shown to be a promising therapeutic strategy for acute myeloid
