The clinically used androgen receptor (AR) antagonists (bicalutamide, flutamide and nilutamide) bind with low affinity to AR and can induce escape mechanisms. Furthermore, under AR gene amplification or mutation conditions they demonstrate agonist activity and fail to inhibit AR, causing relapse

Colorectal cancer (CRC) is a serious health problem throughout the world. 5-Flurouracil, the first-line chemotherapy of colorectal cancer often produces more toxicity to neighboring cells; however, it is still used for CRC treatment. To overcome this, umbelliferone (UMB), a less toxic bioflavonoid
Effects of umbelliferone isolated from the Ferulago pauciradiata Boiss. & Heldr. Plant on cecal ligation and puncture-induced sepsis model in rats.

Sepsis is a pathophysiological event involving systemic inflammatory response syndrome, multiple organ failure syndromes, and tissue damage. Overproduction of free radicals as a result of tissue damage during sepsis contributes to cellular toxicity, organ failure, and even mortality. Antioxidants,

Since the conception of the pentavalent technetium polynuclear complex of dimercaptosuccinic acid, Tc(V)-DMS, a great number of papers published on its clinical applicability forced us to question "how tumor tissue appropriates the Tc(V)-DMS." Preliminary in vitro studies with Ehrlich ascites tumor

OBJECTIVE
Inflammation is associated with various types of acute and chronic alcohol liver diseases. In this study, we examined whether umbelliferone (7-hydroxycoumarin, UF) ameliorates chronic alcohol-induced liver damage by modulating inflammatory response and the antioxidant system.
METHODS
Rats
Anti‑inflammatory effects of 6‑formyl umbelliferone via the NF‑κB and ERK/MAPK pathway on LPS‑stimulated RAW 264.7 cells.

Inhibition of over‑activated inflammation has been demonstrated as one of the most efficient strategies for treating inflammatory diseases. In the present study, 6‑formyl umbelliferone (6FU) was used to evaluate its anti‑inflammatory effects on lipopolysaccharide (LPS)‑stimulated RAW 264.7

OBJECTIVE
We recently reported the potential antioxidant and anti-inflammatory activities of umbelliferone 6-carboxylic acid (UMC) isolated from the whole plants of Angelica decursiva. In this study, we elucidated the anti-inflammatory mechanisms of UMC in vitro and in vivo.
METHODS
The inhibitory

Umbelliferone (UMB) is a coumarin derivative present in roots and barks of plants, such as Angelica decursiva, Artemisia capillaris, and orange. UMB has been previously reported to exhibit anti-inflammatory, anti-diabetic, and anti-cancer effects. However, the effect of UMB on atopic dermatitis (AD)

Oxyprenylated compounds (i.e., ferulic acid and coumarin derivatives) demonstrate neuroprotection and anticancer properties as reported in previous studies. We have tested the affinity of oxyprenylated ferulic acid (1-4) and umbelliferone derivatives (5-11) to melatonin receptors as well as their
Inhibition of MMP-2 secretion from brain tumor cells suggests chemopreventive properties of a furanocoumarin glycoside and of chalcones isolated from the twigs of Dorstenia turbinata.

A furanocoumarin glycoside new named turbinatocoumarin (1) was isolated from the twigs of Dorstenia turbinata. The structure of turbinatocoumarin (1) was assigned as 5-methoxy-3-[3-(beta-glucopyranosyloxy)-2-hydroxy-3-methylbutyl]psoralen by means of spectroscopic analysis. Known compounds have also
