Phytochemical analysis, antioxidant activity and modulatory effect of aqueous leaf extract of L on oxaliplatin-induced oxidative stress in isolated rat liver mitochondria.

This study evaluates the antioxidant effects of aqueous leaf extract of (ALEPL) and its potential to counteract oxaliplatin (OXA)-induced mitochondrial oxidative stress in rat livers, a common side effect of chemotherapy in cancer treatment. Bioactive compounds were identified using High-Performance Liquid Chromatography coupled with Tandem Mass Spectrometry (HPLC-MS and MS), with Fourier-Transform Infrared Spectroscopy (FTIR) and Atomic Absorption Spectrophotometry (AAS) for chemical and mineral analysis. ALEPL showed notable antioxidant activity, with IC50 values of 4.

Ferulenol, a Sesquiterpene Coumarin, Induce Apoptosis via Mitochondrial Dysregulation in Lung Cancer Induced by Benzo[a]pyrene: Involvement of Bcl2 Protein.

Background: Ferulenol, a sesquiterpene coumarin, was extracted from "Ferula vesceritensis" and possesses pro-oxidative and anticancer effects in different types of cancer.

Objective: The objective of this study is to determine whether ferulenol has an anticancer effect by regulation the Bcl2 protein expression in lung cancer induced by benzo[a]pyrene in Wistar rats.

Methods: Rats in group 1 have received, intraperitoneally, olive oil and considered as controls, animals of group 2 were treated with 100 mg/kg of benzo[a]pyrene intraperitoneally in order to induce lung cancer for 24 weeks, the 3rd groups of rats received the ferulenol 50 mg/kg intraperitoneally after 24 weeks of administration of benzo[a]pyrene and the last group, the rats were treated with ferulenol alone 50 mg/kg.

Ethanolic Extract of Algerian Propolis and Galangin Decreased Murine Melanoma Tumor Progression in Mice.

Melanoma is the more dangerous skin cancer, and metastatic melanoma still carries poor prognosis. Despite recent therapeutic advances, prolonged survival remains rare and research is still required. Propolis extracts from many countries have attracted a great deal of attention for their biological properties.

Disruption of mitochondrial membrane potential by ferulenol and restoration by propolis extract: antiapoptotic role of propolis.

This paper reports an investigation of the ability of propolis extract (a resinous substance collected by honeybees from various plant sources) to restore the collapse of mitochondrial membrane potential induced by ferulenol, a sesquiterpene prenylated coumarin derivative isolated from the plant Ferula vesceritensis . We show that ferulenol was able to induce the permeability transition pore (PTP) opening. This effect is caused by the interaction of the compound with the mitochondrial respiratory chain, more particularly by the fall of membrane potential and the inhibition of complex II.

Efficiency of propolis extract against mitochondrial stress induced by antineoplasic agents (doxorubicin and vinblastin) in rats.

To assess the oxidative stress and mitochondrial dysfunction associated with disease, toxic process and aging, in vivo and in vitro preventive effect of propolis extract against mitochondrial oxidative stress induced by two anticancer drugs (doxorubicin and vinblastin) have been investigated in female wistar rat using liver and heart mitochondria. The results show that doxorubicin and vinblastin altered mitochondrial functions as observed by a decrease in respiratory control value, an activation of swelling and overproduction of superoxide anion. Myocardial tissue from doxorubicin treated rats showed a marked increase in malondialdehyde production, a depletion of reduced glutathione contents and an inhibition of catalase and superoxide dismutase activities.
