Multiplex planar bioassay detecting estrogens, antiestrogens, false-positives and synergists as sharp zones on normal phase

A. Ronzheimer et al.

Summary: By reducing zone diffusion on NP plates and developing a multiplex bioassay, the study successfully identified hormonal activities in botanicals and provided insights into unknown hormonally active compounds. This streamlined approach can be used to differentiate hormonal effects in complex samples and improve understanding of phytoestrogens.

Essential Oils as Multicomponent Mixtures and Their Potential for Human Health and Well-Being

Marek Bunse et al.

Summary: Essential oils and their individual volatile organic constituents have been used for thousands of years and have various applications in perfumes, cosmetics, and healthcare. They possess antibacterial, antiviral, and anti-inflammatory properties and have been used for both therapy and prevention of diseases. Essential oils are complex mixtures obtained from natural plant materials, and their multi-component composition contributes to their diverse pharmacological potential. They are already widely used in aromatherapy, inhalation therapy, and topical administration for managing various health conditions.

Effect-directed profiling of Ficus religiosa leaf extracts for multipotent compounds via 12 effect-directed assays

Vandana Gawande et al.

Summary: Interest in the therapeutic potential of natural compounds from plants is increasing worldwide due to shortcomings in the development of modern synthetic drugs. A new HPTLC method was developed to analyze individual compounds in Ficus religiosa leaves from India and Germany, revealing bioactive compounds with antibiotic, enzyme inhibitory, and radical scavenging activities. No estrogen-like or genotoxic compounds were detected.

Determination of tyrosinase-cyanidin-3-O-glucoside and (-/ plus )-catechin binding modes reveal mechanistic differences in tyrosinase inhibition

Kyung Eun Lee et al.

Summary: The study investigated the inhibitory mechanisms of cyanidin-3-O-glucoside and (-/+)-catechin on tyrosinase using computational simulations and in vitro assessments. Molecular docking and dynamics simulations indicated a stable binding of the flavonoids with tyrosinase, with (-/+)-catechin showing substantial inhibition. The findings suggest further research on (-/+)-catechin as a potential drug candidate for tyrosinase-related diseases.
