Aim of the study was to assess dihydrocodeine (DHC) and metabolites concentrations and their correlations with DHC analgesia in cancer patients with pain. Thirty opioid-naive patients with nociceptive pain intensity assessed by VAS (visual analogue scale) > 40 received controlled-release DHC as the first (15 patients, 7 days) or as the second opioid (15 patients, 7 days). Blood samples were tak...
Dehydrocorydaline (DHC), a quaternary alkaloid from Corydalis yanhusuo, has been demonstrated to be the active constituent in the treatment of coronary heart disease. In this study, a high-performance liquid chromatography-electrospray ionization-triple quadrupole linear ion trap mass spectrometry (HPLC-ESI-QTRAP MS) technique was used to identify DHC metabolites in plasma and bile after oral a...
The ontogenetic variation of total and individual capsaicinoids (nordihydrocapsaicin (n-DHC), capsaicin (C), dihydrocapsaicin (DHC), homocapsaicin (h-C) and homodihydrocapsaicin (h-DHC)) present in Malagueta pepper (Capsicum frutescens) during fruit ripening has been studied. Malagueta peppers were grown in a greenhouse under controlled temperature and humidity conditions. Capsaicinoids were ex...
Dehydrocorydaline (DHC) is an alkaloidal component isolated from Rhizoma corydalis. Previous studies have shown that DHC has anti-inflammatory and anti-tumor effects and that it can protect the cardiovascular system. However, there are few studies of the antinociceptive effects of DHC in vivo. This study explored the antinociceptive effects and possible mechanisms of DHC in mice using two infla...
BACKGROUND Dihydrocorynantheol (DHC) is an alkaloid compound isolated from Esenbeckia leiocarpa Engl. that has demonstrated anti-inflammatory properties in experimental models. The aim of this study was to investigate whether the modification of the chemical structure of DHC could alter its anti-inflammatory effect in a mouse model of pleurisy induced by carrageenan. METHODS DHC was isolated ...
2',4'-Dihydroxychalcone (2',4'-DHC) was identified from a heat shock protein 90 (Hsp90)-targeting library as a compound with Hsp90 inhibitory and antifungal effects. In the presence of 2',4'-DHC (8 µg/mL), radial growth of Aspergillus fumigatus was inhibited 20% compared to the control, and green pigmentation was completely blocked. The expression of the conidiation-associated genes abaA, brlA,...
Endoplasmic reticulum (ER) stress causes cell survival or death, which is dependent on the type of cell and stimulus. Capsaicin (8-methyl-N-vanillyl-6-nonenamide) and its analog, dihydrocapsaicin (DHC), induced caspase-3-independent/-dependent signaling pathways in WI38 lung epithelial fibroblast cells. Here, we describe the molecular mechanisms induced by both chemicals. Exposure to capsaicin ...
AIMS Atherosclerosis is a chronic inflammatory disease and represents the major cause of cardiovascular morbidity and mortality. There is evidence that dihydrocapsaicin (DHC) can exert multiple pharmacological and physiological effects. Here, we explored the effect of DHC in atherosclerotic plaque progression in apoE(-/-) mice fed a high-fat/high-cholesterol diet. METHODS AND RESULTS apoE(-/-...
To identify domains in the dynein heavy chain (Dhc) required for the assembly of an inner arm dynein, we characterized a new motility mutant (ida2-6) obtained by insertional mutagenesis. ida2-6 axonemes lack the polypeptides associated with the I1 inner arm complex. Recovery of genomic DNA flanking the mutation indicates that the defects are caused by plasmid insertion into the Dhc10 transcript...
The traditional Chinese medicine component dehydrocostuslactone (DHC) isolated from Saussurea costus (Falc.) Lipschitz, has been shown to have anti-cancer activity. Angiogenesis is an essential process in the growth and progression of cancer. In this study, we demonstrated, for the first time, the anti-angiogenic mechanism of action of DHC to be via the induction of cell cycle progression at th...
