A series of clinafloxacin triazole hybrids as a new type of antibacterial and antifungal agents were synthesized for the first time and screened for their antimicrobial efficacy against four Gram-positive bacteria, four Gram-negative bacteria and two fungi by two fold serial dilution technique. The bioactive assay indicated that most of the target compounds displayed broad antimicrobial spectrum and good antibacterial and antifungal activities with low MIC values ranging from 0.25 to 2 μg/mL against all the tested strains which exhibited comparable or even better efficiency in comparison with the reference drugs Chloramphenicol, Clinafloxacin and Fluconazole, respectively. Notably, some synthesized clinafloxacin triazoles showed stronger efficacy against methicillin-resistant Staphylococcus aureus than their parent Clinafloxacin.

This review article explores the potential applications of chitosan, a natural polysaccharide derived from crustacean shells, in the treatment of seborrheic dermatitis (SD) and other skin diseases. SD is a common chronic inflammatory skin condition characterized by erythema, scaling, itching, and an oily appearance, predominantly affecting areas rich in sebaceous glands. Current treatments, including antifungal agents, corticosteroids, and calcineurin inhibitors, offer symptomatic relief but have limitations in long-term use due to side effects and resistance issues.

As antibiotic-resistant bacteria emerge, antimicrobial peptides have become a promising alternative due to their safety, low residue, and low resistance properties. This study evaluated the in vitro antibacterial activity of peptides obtained from the fermentation of a halotolerant Lactiplantibacillus plantarum CH. Moreover, an in silico antimicrobial activity of L.

Edenia gomezpompae, an endophytic fungus derived from plants, produced a diverse array of preussomerins, a type of spirobisnaphthalenes featuring two spiroketal groups, which exhibited significant antibacterial, antifungal, and cytotoxic activities. Structurally, the biosynthesis of preussomerins might be related to the biosynthesis of 1,8-dihydroxynaphthalene (DHN), a precursor of DHN-melanin. However, the absence of efficient gene-editing tools for E.

The discovery of novel anti-leishmanial compounds is essential due to the limitations of current treatments and the lack of new drugs in development. In this study, we employed the Quasi Vivo 900 medium perfusion system (QV900, Kirkstall Ltd, UK) to simulate physiological fluid flow, allowing us to compare macrophage responses and therapeutic outcomes under dynamic versus static conditions. After 24 hours, phagocytosis and macropinocytosis decreased in all cell types under flow conditions compared to static cultures.

Plant-based essential oils are currently targeted sources because of their non-toxic, bioactivity, and safety of non-targeted organisms. Various volatile components such as terpenoids, phenolics, and alkaloids make it compatible with broad-spectrum applications. In the current study, essential oil from Citrus hystrix DC.
