    Meso-dihydroguaiaretic acid and licarin A of Machilus thunbergii protect against glutamate-induced toxicity in primary cultures of a rat cortical cells.[Pubmed: 16151440]
    Among the lignans, meso-dihydroguaiarectic acid (MDGA) and Licarin A significantly attenuated glutamate-induced neurotoxicity when added prior to or right after the excitotoxic glutamate challenge. 3 The neuroprotective activities of two lignans appeared to be more effective in protecting neurons against neurotoxicity induced by NMDA than that induced by kainic acid. 4 MDGA and Licarin A diminished the calcium influx that routinely accompanies with the glutamate-induced neurotoxicity, and inhibited the subsequent overproduction of cellular nitric oxide and peroxide to the level of control cells. They also preserved cellular activities of antioxidative enzymes such as superoxide dismutase, glutathione peroxidase and glutathione reductase reduced in the glutamate-injured neuronal cells. 5 Thus, our results suggest that MDGA and Licarin A significantly protect primary cultured neuronal cells against glutamate-induced oxidative stress, via antioxidative activities.

    Neolignan Licarin A presents effect against Leishmania (Leishmania) major associated with immunomodulation in vitro.[Pubmed: 23891943]
    Licarin A anti-leishmanial activity chemically synthesized by our study group. It was observed that Licarin A effectively inhibited Leishmania (Leishmania) major promastigotes (IC₅₀ of 9.59 ± 0.94 μg/mL) growth, by inducing in these parasites genomic DNA fragmentation in a typical death pattern by apoptosis. The antiamastigote activity is associated with an immunomodulatory activity, since treatment with Licarin A of the infected macrophages induced a decrease in the interleukin (IL)-6 and IL-10 production. This study demonstrates for the first time the antileishmanial activity of Licarin A and suggests that the compound may be a promising in the development of a new leishmanicidal agent.

    Antitubercular activity and the subacute toxicity of (-)-Licarin A in BALB/c mice: a neolignan isolated from Aristolochia taliscana.[Pubmed: 23291382]
    (-)-Licarin A (LA) was isolated from diverse plants such as Aristolochia taliscana and possesses antimycobacterial, antiinflammatory, trypanocidal, and neuroprotective activities. The aim of the study was to determine the antitubercular and subacute toxicity of (-)-Licarin A isolated from A. taliscana in BALB/c mice. METHODS: The antitubercular activity of (-)-Licarin A was tested in a TB murine model inducing disease with M. tuberculosis H37Rv or MDR. Mice were treated with (-)-Licarin A (5 mg/kg) for 30 and 60 days; post/treatment, lung bacilli loads and pneumonia percentage were determined. The subacute toxicity of (-)-Licarin A (21 days) was evaluated in healthy mice. After treatment, biochemical and hematological parameters were determined and main organs were analyzed histologically. RESULTS: In animals infected with drug-sensitive or MDR strains, (-)-Licarin A produced a significant decrease of pulmonary bacillary burdens at day 30 of treatment, and a significant pneumonia reduction at days 30 and 60 of treatment. Regarding subacute toxicity, (-)-Licarin A administration during 21 days showed no abnormalities in main-organ macro- and microarchitecture. CONCLUSIONS: (-)-Licarin A reduces pneumonia of mice infected with both mycobacterium strains. Also, subacute toxicity of (-)-Licarin A exhibits no major signs of damage. Biochemical and hematological parameters and histological analyses indicate that (-)-Licarin A caused no significant changes at the doses assayed.

    Schistosomicidal and trypanocidal structure-activity relationships for (±)-licarin A and its (-)- and (+)-enantiomers.[Pubmed: 21570099]
    (±)-Licarin A (1) was obtained by oxidative coupling, and its enantiomers, (-)-Licarin A (2) and (+)-Licarin A (3), were resolved by chiral HPLC. These results suggest that (±)-Licarin A (1) and (-)-Licarin A (2) are promising compounds that could be used for the development of schistosomicidal and trypanocidal agents.
