    Conjugation Assay:

    Article Title: Synthesis, molecular dynamics, and antimicrobial evaluation of peptide-antibiotic conjugates designed for dual-mechanism pathogen inhibition
    Article Snippet: Conjugation with norfloxacin ( 2a ) increased potency relative to peptide 2 in 9 of 13 strains (median 2.3-fold), with the largest gains observed against C. parapsilosis ATCC 22019 and S. enterica ATCC BAA-2162 (14-fold each) and L. monocytogenes DSMZ 115292 (7.0-fold). .. Notably, the four strains for which 2a underperformed relative to peptide 2 ( B. subtilis ATCC 11774, S. aureus ATCC 29213, C. albicans ATCC 1386, S. pyogenes ATCC 12344; all 0.6-fold) were precisely those against which the unconjugated peptide 2 already displayed some of its lowest MIC values , suggesting that conjugation trades a modest loss of potency where the parent peptide’s intrinsic membrane-disruptive activity is already near-maximal for a broadened, more consistent spectrum across strains where peptide 2 alone is weak or inactive. .. Conjugation with metronidazole ( 2b ) showed a more mixed pattern (median 0.7-fold, indicating a modest net reduction in potency relative to peptide 2 ), but with clear, strain-specific gains against E. faecalis ATCC 29212 (2.6-fold), L. monocytogenes DSMZ 115292 (2.5-fold), and, to a lesser extent, S. enterica ATCC BAA-2162 and A. terreus DSMZ 23081 (1.3-fold each), which is consistent with the improved potency of 2b against facultative anaerobic strains.

    Article Title: Janus CMC-based hydrogel with multifunctional synergy for hemostasis and wound healing.
    Article Snippet: Timely hemostasis, bacterial inhibition, and accelerated tissue regeneration are core demands for clinical wound care.. However, integrating robust wet adhesion and surface antifouling performance simultaneously remains a key bottleneck limiting conventional wound dressings.. Herein, a carboxymethyl cellulose (CMC)-based drugloaded hydrogel (DLCH) co-embedded with polyhexamethylene biguanide-loaded zeolite (PHMB@Zeo) and gelatin-dopamine-stabilized silver nanoparticles (Gel-DA-AgNPs) was rationally developed as the bottom functional therapeutic layer.

    Article Title: Chemical composition and biological capacity of essential oils and ethanol extracts from endemic Nepeta species in the Armenian flora.
    Article Snippet: The chemical composition and biological activities of Nepeta species growing in Armenia were investigated.. The essential oil composition was analysed using gas chromatography–mass spectrometry, which revealed the presence of key sesquiterpenes such as copaene (12.59%) and β-elemene (3.77%) across all samples.. Antioxidant activity of the ethanolic extracts was evaluated via the DPPH radical scavenging assay, and total flavonoid content was determined, with N. sulphurea from Mantash showing the highest total flavonoid content (1.17 ± 0.23 mg RE/g DW).

In this study, the short cationic antimicrobial peptide RK-14 (RIWKIWKKIWKIWK-NH2) was designed using an integrated artificial intelligence (AI)and machine learning (ML)-assisted approach and subsequently evaluated using computational predictions and in vitro analyses.. RK-14 exhibited bactericidal activity against methicillin-resistant Staphylococcus aureus and ESBL-positive Escherichia coli, with MICs of 16–64 μM and MBCs of 32–128 μM.
