Involvement of the serotoninergic system in the anxiolytic action mechanism of a liposomal formulation containing nimodipine (NMD-Lipo).

In the search for anxiolytic drugs with fewer adverse effects, calcium blockers were proposed as a benzodiazepines (BZDs) alternative. In this context, the anxiolytic effect of nimodipine has been demonstrated. However, its low bioavailability and solubility could be improved by using nanostructured drug delivery systems such as liposomes.

Citrinin as a potential anti-cancer therapy: A comprehensive review.

Citrinin (CIT) is a polyketide-derived mycotoxin, which is produced by many fungal strains belonging to the gerena Monascus, Aspergillus, and Penicillium. It has been postulated that mycotoxins have several toxic mechanisms and are potentially used as antineoplastic agents. Therefore, the present study carried out a systematic review, including articles from 1978 to 2022, by collecting evidence in experimental studies of CIT antiplorifactive activity in cancer.

Cytotoxic and mutagenic effects of the food additive tartrazine on eukaryotic cells.

Background: Among the food additives used in the food industry, food dyes are considered the most toxic. For instance, tartrazine (TRZ) is a food colorant commercially available with conflicting data regarding its cytotoxic, genotoxic, and mutagenic effects. Therefore, this study aimed to evaluate the cytotoxic and mutagenic potential of TRZ using different eukaryotic cells (in vitro).

Antiproliferative and Genotoxic Action of an Underexploited Organoteluran Derivative on Sarcoma 180 Cells.

Background: The search for novel metallic chemical compounds with toxicogenic effects has been of great importance for more efficient cancer treatment.

Objective: The study evaluated the cytotoxic, genotoxic and mutagenic activity of organoteluran RF07 in the S-180 cell line.

Methods: The bioassays used were cell viability with 3-(4,5-dimethyl-2-thiazole)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) test, evaluation of apoptosis and necrosis using fluorescence and flow cytometry, cytokinesisblock micronucleus test and comet assay.

Anti-Cancer Effects of Asiatic Acid, a Triterpene from Centilla asiatica L: A Review.

Background: Centilla asiatica L is a medicinal herb that has been widely used in folk medicine to treat various diseases. Asiatic Acid (AA), a triterpene and a known component of this herb, has been shown to display important biological activities, including anti-inflammatory, antibacterial, antidiabetic and antihyperlipidemic, neuroprotective, anxiolytic and antidepressant, hepatoprotective, pancreas protective, and cardio- protective.

Objective: This review focuses on AA's anti-cancer effects on the basis of published literature found in a number of databases such as PubMed and Science Direct.

Effect of Diterpenes on Hepatic System.

Complication in the hepatic system is a major concern for human being. To control and keep the hepatic system healthy, a number of measures, including drug treatments are considered. Diterpenes are essential oils having promising antioxidant and cytotoxic properties along with their genotoxic and mutagenic effects.

Assessment of chemotherapy on various biochemical markers in breast cancer patients.

Chemotherapy is a standard treatment method for the patients with locally advanced breast cancer. Lately, cyclophosphamide (CYP) and doxorubicin (DOX) are used as the major chemotherapeutic agents especially for the treatment of breast cancer. Till date, no serum biomarker has been able to provide an early diagnosis of breast cancer.

Evaluation of Antioxidant Activity of Phytol Using Non- and Pre-Clinical Models.

Background: Phytol (3,7,11,15-tetramethylhexadec-2-en-1-ol; PHY), the alcoholic diterpenoid is particularly interesting due to its diverse activities found in literature. This study evaluated in vitro and in vivo antioxidant capacity of PHY.

Methods: We conducted DPPH• (2,2-diphenyl-1-picrylhydrazyl) and ABTS•+ (2,2'-azino-bis(3- ethylbenzthiazoline-6-sulphonic acid)) radical scavenging tests as in vitro, while Saccharomyces cerevisiae test as in vivo.

Genotoxic and Mutagenic Activity of PT-31.

Toxicity assessment is an important tool in drug discovery and development. PT-31 (3-(2-chloro-6-fluorobenzyl)-imidazolidine-2,4-dione) is an imidazolidine- 2,4-dione analogue of clonidine that displays a dose-dependent analgesic profile and synergism with morphine. This study investigated genotoxic and mutagenic effects of PT-31 in Swiss mice.

Investigation of biological activities of dichloromethane and ethyl acetate fractions of Platonia insignis Mart. seed.

Platonia insignis Mart., a native species of the Brazilian Amazon more commonly known as bacuri, is a member of the Clusiaceae family. In this study, we evaluated the chemical composition and the antioxidant and toxicity activities of the dichloromethane and ethyl acetate fractions from P.

Genotoxicity of sodium metabisulfite in mouse tissues evaluated by the comet assay and the micronucleus test.

Sodium metabisulfite (SMB, Na(2)S(2)O(5)) is widely used in the food and pharmaceutical industries, because of its ability to inhibit proliferation of microorganisms and its antioxidant properties. We have evaluated the genotoxic effects of SMB on different tissues of the mouse, by use of the comet assay (liver and blood cells) and the micronucleus test (blood and bone marrow cells). For all tissues, significant increases in damage index and damage frequency values were observed in the SMB-treated groups (1 and 2g/kg doses) compared to the control animals.
