    Protective effect of compounds from the flowers of Citrus aurantium L. var. amara Engl against carbon tetrachloride-induced hepatocyte injury.[Pubmed: 23985451]
    5-Hydroxy-6,7,3',4'-tetramethoxyflavone (HTF), Limonexic acid (LA) are two compounds isolated from the flowers of Citrus aurantium L. var. amara Engl with various biological activities.
    This study was designed to investigate their protective effects against carbon tetrachloride (CCl4)-induced hepatocyte injury, using human hepatic cell line HL-7702 to determine the cell cytotoxicity, cell viability, levels of hepatic marker enzymes, malondialdehyde (MDA). Results showed that pretreatment with HTF, Limonexic acid could significantly reverse CCl4-induced HL-7702 cell viability decrease, Limonexic acid displayed a higher activity. HTF, Limonexic acid also showed their capability of decreasing the CCl4-induced leakage of lactate dehydrogenase (LDH), aspartate aminotransferase (AST), inhibiting the lipid peroxidation, HTF showed more significant activity.
    Given that HTF, Limonexic acid were not toxic, it is concluded that HTF, Limonexic acid could effectively protect hepatocyte against CCl4-induced injury.

    Antinociceptive action of limonexic acid obtained from Raulinoa echinata.[Pubmed: 17976270]
    The antinociceptive effect of the Limonexic acid isolate of Raulinoa echinata Cowan in four models of pain in mice is described.
    When evaluated against acetic acid-induced abdominal constrictions, Limonexic acid (10, 30 and 60 mg kg(-1), i.p.) produced dose-related inhibition of the number of constrictions, with a mean ID50 value of 43 (2.3-79) micromol kg(-1), and was more potent than some standard drugs. In the formalin test, Limonexic acid inhibited both the first and second phases of formalin-induced pain. Furthermore, the effect was more pronounced in the second phase, with a mean ID50 value of 13.66 (9.35-19.61) micromol kg(-1), and had a pharmacological profile that was similar to standard drugs such as acetaminophen and acetyl salicylic acid. Limonexic acid also produced dose-related inhibition of glutamate- and capsaicin-induced pain, with mean ID50 values of 11.67 (8.51-16.0) micromol kg(-1) and 47.17 (36.51-60.93) micromol kg(-1), respectively.
    The mechanism of action is not completely understood, but seems to involve direct interaction with the GABAergic and nitroxidergic pathways.

    Limonoids and their anti-proliferative and anti-aromatase properties in human breast cancer cells.[Pubmed: 23117440]
    Lemons are a widely used citrus crop and have shown several potential health benefits. In the present study, the mechanism and effectiveness of the anti-cancer and anti-aromatase properties of limonoids were investigated for the first time. Defatted lemon (Citrus lemon L. Burm) seed powder was extracted with ethyl acetate (EtOAc) and methanol (MeOH) for 16 h each, successively.
    These extracts were fractionated using 1D (silica) and 2D (ion exchange and SP-70 columns) column chromatography to obtain nine limonoids. The compounds were identified by TLC, HPLC, and LC-MS techniques. A panel of 9 purified limonoids, including limonin, nomilin, obacunone, Limonexic acid (LNA), isoLimonexic acid (ILNA), nomilinic acid glucoside (NAG), deacetyl nomilinic acid glucoside (DNAG), limonin glucoside (LG) and obacunone glucoside (OG) as well as 4 modified compounds such as limonin methoxime (LM), limonin oxime (LO), defuran limonin (DL), and defuran nomilin (DN), were screened for their cytotoxicity on estrogen receptor (ER)-positive (MCF-7) or ER-negative (MDA-MB-231) human breast cancer cells. We further tested the mechanism of the anti-proliferative activity of limonoids using an in vitro aromatase enzyme assay and western blot with anti-caspase-7. Among the tested limonoids, 11 limonoids exhibited cytotoxicity on MCF-7 whereas 8 limonoids showed cytotoxicity against the MDA-MB-231 cell lines. Although most of the limonoids showed anti-aromatase activity, the inhibition of proliferation was not related to the anti-aromatase activity. On the other hand, the anti-proliferative activity was significantly correlated with caspase-7 activation by limonoids.
    Our findings indicated that the citrus limonoids may have potential for the prevention of estrogen-responsive breast cancer (MCF-7) via caspase-7 dependent pathways.
