Bioactive peptides are part of an innate response elicited by most living forms. In plants, they are produced ubiquitously in roots, seeds, flowers, stems, and leaves, highlighting their physiological importance. While most of the bioactive peptides produced in plants possess microbicide properties, there is evidence that they are also involved in cellular signaling. Structurally, there is an overall similarity when comparing them with those derived from animal or insect sources. The biological action of bioactive peptides initiates with the binding to the target membrane followed in most cases by membrane permeabilization and rupture. Here we present an overview of what is currently known about bioactive peptides from plants, focusing on their antimicrobial activity and their role in the plant signaling network and offering perspectives on their potential application.

Ophthalmic Formulation

Aloin and polysaccharide present in extracts of Aloe arborescens Miller were formulated into a binary solution to protect eyes from bacterial infection and ultraviolet radiation (UVR). The UVR absorption spectrum was recorded from 190 to 440 nm using a UV spectrometer. The physical properties of the product were examined in terms of its appearance, odor, pH, viscosity, density, refractive index, and stability. The binary solution exhibited three absorption peaks in the UVA, B and C regions, respectively. Such UV absorption capability was attributed to the phenolic chromophores pertaining to aloin. The present study suggested that the formulated binary solution has potential application as an UV absorption agent with built-in antimicrobial activity.

This research describes the synthesis and in vitro antimicrobial activity study of a series of 2,4,6-trimethylbenzenesulfonyl hydrazones. Twenty-five hydrazones (2–26) were synthesized on the basis of condensation reaction. The in vitro bioactivity study confirmed the potential application of obtained derivatives as antimicrobial agents. Among the tested compounds, the highest activity was discovered for derivative 24, which possessed minimal inhibitory concentration (MIC) ranging from 7.81 to 15.62 µg/mL against Gram-positive reference bacterial strains. Synthesized benzenesulfonyl hydrazones can be applied as potential ligands for the synthesis of bioactive metal complexes.

New 2-((4-methylphenoxy)methyl)-N-(arylcarbamothioyl)benzamides, prepared from 2-(4- methyl-phenoxymethyl)benzoyl chloride via isothiocyanate formation followed by treatment with various substituted amines, were tested for their antimicrobial features. Despite their weak antimicrobial activity, some of the tested derivatives inhibited the microbial biofilm development on the inert substrata, encouraging further studies of their potential application as anti-biofilm agents.

Lysimachia vulgaris L., also known as yellow loosestrife, is an herbaceous perennial flowering plant from the family Primulaceae. Traditionally, L. vulgaris has been commonly used in Chinese medicine to increase urination, reduce fever, and treat sexually transmitted ailments. This study aimed to investigate phenolic content, antioxidant activity, and antimicrobial potential of L. vulgaris aerial part (LVA) and root (LVR) methanol extracts. Based on the spectrophotometric determination, both extracts possessed a high level of phenolic compounds. The content of total phenolic compounds (130.14 mg GAE/g) and condensed tannins (120.58 mg GAE/g) was higher in LVR, while total flavonoid (206.93 mg QUE/g) and flavanol (17.02 RUE/g) contents were higher in LVA. DPPH and ABTS assays were used to estimate the antioxidant activity of the extracts, whereby LVR showed better antioxidant potential in both applied methods. The extracts inhibited the growth of most of the tested bacterial and fungal strains with minimal inhibitory concentration values (MICs) ranged between (˂ 0.3125 to 20 mg/mL), whereby the significantly higher antimicrobial activity of LVR was observed. Based on the obtained results, the significant antioxidant and antimicrobial activity of L. vulgaris root extract may be a basis for its further research and potential application in the pharmaceutical and food industry.
