Background: Antioxidants are the substances that interact inside and outside of a biological system against the damaging effects of highly reactive free radicals produced during metabolism. Among various natural alternative sources of bioactive metabolites, endophytic fungi have emerged as a significant reservoir of potent antioxidant compounds. These scantly explored micro-organisms are prolific producers of novel compou Read More

Background: It is always thought that traditional herbal drugs are safe, effective and economical and are used worldwide for healing purposes. Aegle marmelos, belonging to family Rutaceae, is an important medicinal plant of the indigenous medicine system in India. Despite the study on ethnobotanical uses and the presence of bioactive compounds, there was only a handful of research on A. marmelos. The therapeutic u Read More

Background: Since its inception, people are using herbal extracts as natural remedies for the treatment of various diseases. Bryophyllum pinnatum, also known as the air plant, is a well-recognized herb used in folk medicine. It is native to Madagascar and further planted in tropical and subtropical areas around the world. It is known for the profusion of miniature plantlets which arise from the margins of phylloclade. Obje Read More

Coumarins are a set of polyphenolic compounds isolated from plant product tonka bean, coumarou in 1820. They belong to the family of benzopyrones, which includes benzene ring joined with the aid of a pyrone ring. Coumarins have attracted great attention of medicinal chemists and pharmacologists in recent years as they been confirmed to bear diverse pharmacological activities like antiinflammatory and analg Read More

Background: Melanoma is a highly aggressive form of skin cancer and is responsible for the majority of the deaths related to this pathology. Recently, different studies have identified naturally occurring compounds of fruits with chemopreventive action. This systematic review aims to investigate the protective role of fruit phytochemicals against melanoma skin cancer from in vitro studies. Methods: The articles were se Read More

Background: Currently, a study on the relationship between candidiasis and cancer has been conducted. Until recent years, the opportunistic fungus C. albicans is mainly associated with cancer processes and is able to stimulate carcinogenesis and metastasis. Methods: A number of ionic liquids as potential anticancer and anti-Candida agents have been investigated based on modern theoretical and experimental data abo Read More

Background: Glycyrrhizic Acid (GA) is the major triterpene saponin of licorice roots. The most important derivative of GA is its monoammonium salt (glycyram, GC). Some pharmacological properties of triterpene saponins explain their molecular complexation with Cholesterol (Chol). However, the molecular complexation of GC with Chol has not been proven. The functional groups of GA and GC involved in the interactions with C Read More

Background: Polyalthia longifolia which originates from India is rich with various useful phytochemicals which are valuable for human health. Accordingly, the current study was conducted to evaluate the combinational antimicrobial activity of P. longifolia Ethyl Acetate Fraction (PLEAF) with ampicillin, antioxidant and cytotoxicity activities. Methods: The evaluation of the synergistic activity of PLEAF fraction and ampicillin agai Read More

Background: Meso-tetra-4-actophenyl-porphyrin (TAcPPH2) was synthesized by reacting 4- acetyl-benzaldehyde with pyrrole in propionic acid, and used as a ligand for the synthesis of palladium (II) complex (PdTAcPP). The structure of the ligand and the complex were characterized by NMR and electronic spectroscopy. Methods: The antioxidant activity and the binding parameters of both the ligand and its complex with superoxid Read More

Background: Ellagic Acid (EA) is a polyphenolic compound that is classified in the natural antioxidants group. Polyphenolic compounds that exert antioxidant activity possess particular importance for scientists, food producers and consumers due to their positive effects on human health. However, despite considerable evidence that EA shows antigenotoxic activity by binding to DNA, there is no systematic genotoxicity stud Read More

Background: Aspergillus Versicolor is a marine-derived fungus isolated from Hyrtios Erectus Red Sea sponge. Methods: The aim of this study was to carry out a pharmacological screening and investigation for the in vitro biological activity (antioxidant, cholinergic, antidiabetic and anticancer) of Aspergillus Versicolor crude extract’s active compounds by using different qualitative and quantitative methods. Results: The present stu Read More

Background: Motivated by the need for bioprospecting new drug studies have revealed a variety of secondary metabolites with biological activity. In particular, antimicrobial research confronts the growing reality of resistance of microorganisms to currently available drugs. Modifications in the chemical structure of secondary metabolites may be important in the development of a product to improve the efficacy of these compo Read More

Background: The assessment of underexploited leaves has become crucial to supplement the rapidly depleting sources of bioactive components as well as provide available nutrient sources for local inhabitants. Methods: This study thus investigated the bioactive components of the oil, and fatty acid composition, free radical scavenging potentials, and protein qualities of leaves of Z. mays and G. celosioides using standard metho Read More

Introduction: Cancer is still an untreatable disease and the second leading cause of death globally. The heterocyclic compounds have always played a major role in the anticancer drug discovery program. 1,2,4-Triazine-6-ones is a heterocyclic privileged structure with diversified activities. In the presented study, 21 novel 2,5-disubstituted-3-phenyl-1,2-dihydro-1,2,4-triazin-6 (5H)-one derivatives (13(a-k), 18(a-j) and 21(a1-a4, b)) h Read More
