Serum interferon gamma (IFNγ) was augmented in both healthy and tumor-bearing animals (P < 0...

Naturally occurring coumarins 7-isopentenyloxycoumarin, auraptene, and umbelliprenin are able to modulate the biosynthesis of melanin in murine Melan-a cells probably through the interaction with selected biological targets like estrogen receptor β and aryl hydrocarbon receptor. Such a modulation strictly depends on the individual structure of the coumarin: the presence of a 3,3-dimethylallyloxy side chain is a structural determinant for tanning activation whereas a farnesyl one leads to the opposite effect...

Umbelliprenin (Umb), a natural coumarin, has demonstrated anti-tumor activities, both in vitro and particularly in vivo , in several types of cancer, including lung cancer. The present study aimed to identify molecular targets of Umb using a high-throughput approach. Lung cancer cell lines, QU-DB (large-cell lung carcinoma) and A549 (adenocarcinoma), were treated with Umb. Differentially-expressed proteins were identified using two-dimensional electrophoresis coupled to mass spectrometry. In the QU-DB cells, differential expression of proteins, including downregulation of the tumorigenic protein heat shock protein 90 kDa and upregulation of the potential anti-tumor proteins Nipsnap1 and glycine-tRNA ligase (GRS), suggested that Umb is a strong anti-tumor compound...

An analytical strategy based on different extraction methodologies and HPLC with spectrophotometric (UV-vis) detection has been developed to investigate the presence of and to quantitate biologically active selected unprenylated and O-prenylated phenylpropanoids, namely umbelliferone, 4'-geranyloxyferulic acid, 7-isopentenyloxycoumarin, auraptene, and umbelliprenin in dill (Anethum graveolens L.), anise (Pimpinella anisum L.), and wild celery (Angelica archangelica L.). Absolute ethanol or 7:3 water/ethanol mixtures were seen to be the most powerful extraction solvents to perform "classic" maceration or ultrasound-assisted one in terms of yields in secondary metabolites...

BACKGROUND: Resistance to chemotherapy is a growing concern, thus natural anticancer agents are drawing the attention of many scientists and clinicians. One natural anticancer agent, umbelliprenin, is a coumarin produced by many species of Ferula. OBJECTIVES: We aimed to examine the inhibitory effect of umbelliprenin on human and mouse bone marrow-derived stem cells (BMDSCs), peripheral blood mononuclear cells (PBMCs), and different cancer cell lines. MATERIALS AND METHODS: In this in vitro experimental study, the HT29, CT26, MCF-7, 4T1, A172, and GL26 cancer cells and human and mouse BMDSCs and PBMCs were cultured in RPMI-1640 medium supplemented with 10% fetal bovine serum (FBS), incubated at 37°C for 24 hours in a 5% CO2 atmosphere, and then were treated with different concentrations of umbelliprenin dissolved in dimethyl sulfoxide (DMSO) (3, 6, 12, 25, 50, 100, and 200 µg/mL) for 24, 48, and 72 hours at 37°C...

Cytotoxicity of umbelliprenin has been found in various cancer cell lines such as, prostate, breast, CLL, and skin. Encapsulating chemotherapeutic agents with nanoliposomes have been resulted in improved cytotoxicity effects than their free forms. However, whether nanoliposomal form of umbelliprenin could have higher cytotoxic effect than free umbelliprenin is not clarified yet. After synthesizing umbelliprenin, different concentrations (3, 6, 12, 25, 50, 100, 200 μg/ml) applied on the mouse mammary carcinoma cell line (4T1) for 24, 48, and 72 h at 37°C...
