Bisdemethoxycurcumin Induces apoptosis in activated hepatic stellate cells via cannabinoid receptor 2. PUMID/DOI:25594342 Molecules. 2015 Jan 14;20(1):1277-92. the results demonstrate that Bisdemethoxycurcumin induces apoptosis in activated HSCs, but not in hepatocytes, by impairing cellular energetics and causing a downregulation of cytoprotective proteins, likely through a mechanism that involves CBR2. Bisdemethoxycurcumin attenuates gastric adenocarcinoma growth by inducing mitochondrial dysfunction. PUMID/DOI:25435973 Oncol Lett. 2015 Jan;9(1):270-274. Epub 2014 Nov 7. Bisdemethoxycurcumin (BDMC) is a demethoxy derivative of curcumin. In this study, a human gastric adenocarcinoma xenograft model was generated in vivo using nude mice and BDMC was observed to suppress the growth and activity of tumors, in addition to improving the physical and mental capacity of the mice. An increased number of apoptotic cells, decreased ratio of B-cell lymphoma 2 (Bcl-2)/Bcl-2-associated X protein and increased caspase-3 expression was also observed following treatment with Bisdemethoxycurcumin, indicating that Bisdemethoxycurcumin may promote apoptosis in tumors via mitochondrial modulation. The growth of SGC 7901 gastric cancer cells was inhibited and arrested at G1 phase. Specific indicators of mitochondrial dysfunction, a reduction in adenosine triphosphate generation, the inner mitochondrial membrane potential, augmentation of reactive oxygen species production and cytochrome c were also detected in the mitochondria following treatment with Bisdemethoxycurcumin. These results indicate that Bisdemethoxycurcumin attenuates gastric adenocarcinoma growth by inducing mitochondrial dysfunction. Bisdemethoxycurcumin suppresses MCF-7 cells proliferation by inducing ROS accumulation and modulating senescence-related pathways. PUMID/DOI:23950593 Pharmacol Rep. 2013;65(3):700-9. Bisdemethoxycurcumin significantly inhibited MCF-7 breast cancer cell proliferation, while a rapid rise of the intracellular ROS level accompanied with a reduction of Dym were observed. In addition, Bisdemethoxycurcumin activated the pro-apoptotic protein p53 and its downstream effector p21 as well as the cell cycle regulatory proteins p16 and its downstream effector retinoblastoma protein (Rb). All of these Bisdemethoxycurcumin-induced effects were counteracted with the pre-incubation of the antioxidant N-acetylcysteine (NAC). Bisdemethoxycurcumin inhibits PDGF-induced vascular smooth muscle cell motility and proliferation. PUMID/DOI:23554078 Mol Nutr Food Res. 2013 Sep;57(9):1611-8. Bisdemethoxycurcumin elicited a concentration-dependent inhibition of PDGF-stimulated phosphorylation of PDGF receptor-β, Akt and Erk as well as the PDGF-stimulated SMC migration and proliferation. Bisdemethoxycurcumin was more potent than curcumin in inhibiting migration and proliferation and suppressing PDGF-signaling in SMCs. Both compounds were equipotent in inhibiting PDGF-stimulated generation of intracellular reactive oxygen species. Comparative antiulcer effect of bisdemethoxycurcumin and curcumin in a gastric ulcer model system. PUMID/DOI:19188055 Phytomedicine. 2009 Apr;16(4):342-51. The antiulcer effect of Bisdemethoxycurcumin, a yellow pigment found mainly in rhizomes of Curcuma longa, was compared with curcumin in gastric ulcer model systems to validate its clinical application as a remedy for peptic ulcer. Western blot analysis of mouse macrophage cell line RAW 264.7 activated with lipopolysaccharide showed that Bisdemethoxycurcumin inhibited inducible nitric oxide synthase (iNOS) production significantly but had no effect on tumor necrosis factor-alpha (TNF-alpha) production, whereas curcumin showed stronger suppression of iNOS protein production and inhibited TNF-alpha protein production significantly. However, Bisdemethoxycurcumin and curcumin possessed similar potency in scavenging nitric oxide generated from mouse macrophage cell line RAW 264.7. Reverse-transcriptase polymerase chain reaction (RT-PCR) analysis showed that both curcuminoids inhibited the induction of iNOS dose-dependently at the transcriptional level and curcumin also appeared to inhibit the induction of TNF-alpha at post-transcriptional level. These results indicated that Bisdemethoxycurcumin directly accelerates gastric ulcer healing with potency equal to curcumin. Its antiulcer effect might be due to its properties of decreasing gastric acid secretion and enhancing the mucosal defensive mechanism through suppression of iNOS-mediated inflammation.

Abstract

Exposure to lead is a threat factor for neurodegenerative disorders progress as it could trigger dopaminergic deficiency. We aimed herein to assess the effect of acute lead exposure (25mg/kg B.W i.p.) during three continuous days on the dopaminergic and noradrenergic systems together with locomotor performance in Meriones shawi (M. shawi), then the neuroprotective potential of curcumin-III (30mg/kg B.W) by oral gavage. Pb-exposed M. shawi exhibited increased tyrosine hydroxylase (TH) immunoreactivity in substantia nigra compacta (SNc), ventral tegmental area (VTA), locus coeruleus (LC), and dorsal striatum (DS), unlike the controls. This was correlated with decreased locomotor performance. A noticeable protective effect by co-treatment with curcumin-III was observed; in consequence, TH-immunoreactivity and locomotor disturbance were restored in Pb-treated Meriones. Our data results proved, on the one hand, an evident neurotoxic effect of acute Pb exposure and, on the other hand, a potent therapeutic effect of curcumin-III. Thereby, this compound may be recommended as a neuroprotective molecule for neurodegenerative disorders involving catecholaminergic impairment initiated by metallic elements.

Abstract

Rationale: Recent animal studies reported that curcumin, the active constituent of Curcuma longa, has several central actions and may attenuate morphine tolerance.

Objectives: In the present study, we utilized the intracranial self-stimulation (ICSS) paradigm to examine the effects of the commercially available curcuminoid mixture and each one of its components, individually, on brain stimulation reward and on the reward-facilitating effect of morphine.

Methods: Male Sprague-Dawley rats were implanted with an electrode into the medial forebrain bundle and trained to respond for electrical stimulation using a rate-frequency paradigm. In the first study, rats were injected with graded doses either of the curcuminoid mixture, or curcumin I, or II, or III. In the second study, we examined whether a low dose of the curcuminoid mixture or each individual curcumin analogue composing it could counteract the reward-facilitating effect of morphine.

Results: At low doses, both the curcuminoid mixture and curcumin I did not affect brain stimulation reward, whereas, higher doses increased ICSS thresholds. Curcumin II and curcumin III did not affect brain stimulation reward at any doses. Subthreshold doses of the curcuminoid mixture and curcumin I inhibited the reward-facilitating effect of morphine.

Conclusion: Both the curcuminoid mixture and curcumin I lack hedonic properties and moderate the reward-facilitating effect of morphine. Our data suggest that curcumin interferes with brain reward mechanisms responsible for the expression of the acute reinforcing properties of opioids and provide evidence that curcumin may be a promising adjuvant for attenuating morphine’s rewarding effects in patients who are under long-term opioid therapy.

Abstract

P-glycoprotein (Pgp, ABCB1) is an ATP-dependent drug efflux pump linked to development of multidrug resistance (MDR) in cancer cells. Previously [Biochem Pharmacol 2002;64:573-82], we reported that a curcumin mixture could modulate both function and expression of Pgp. This study focuses on the effect of three major curcuminoids–curcumin I, II and III purified from a curcumin mixture–on modulation of Pgp function in a multidrug resistant human cervical carcinoma cell line (KB-V1). The similar IC(50) values for cytotoxicity of curcuminoids of KB-V1, and KB-3-1 (parental drug sensitive cell line) suggest that these curcuminoids may not be substrates for Pgp. Treating the cells with non-toxic doses of curcuminoids increased their sensitivity to vinblastine only in the Pgp expressing drug resistant cell line, KB-V1, and curcumin I retained the drug in KB-V1 cells more effectively than curcumin II and III, respectively. Effects of each curcuminoid on rhodamine123, calcein-AM, and bodipy-FL-vinblastine accumulation confirmed these findings. Curcumin I, II and III increased the accumulation of fluorescent substrates in a dose-dependent manner, and at 15 microM, curcumin I was the most effective. The inhibitory effect in a concentration-dependent manner of curcuminoids on verapamil-stimulated ATPase activity and photoaffinity labeling of Pgp with the [(125)I]-iodoarylazidoprazosin offered additional support; curcumin I was the most potent modulator. Taken together, these results indicate that curcumin I is the most effective MDR modulator among curcuminoids, and may be used in combination with conventional chemotherapeutic drugs to reverse MDR in cancer cells.
