This study aimed to explore the potency of Gonggong sea snail's (GSS) extract as an antimicrobial peptide (AMP) source. The results showed that the GSS meat extracts exhibited potential antimicrobial activity against and . A peptide band with a molecular weight < 5 kDa was obtained for the characterization of AMP candidates after separating the selected extract using SDS-PAGE, and the sequences were acquired by LC-ESI-MS analysis. The results of the bioinformatics analysis showed that the AMP candidate had a molecular weight of 1.4 kDa, which consisted of 12 amino acid residues (RHPDYSVALLLR), with an α-helix structure, isoelectric point pH (pI) of 9.53, net charge + 1, a total hydrophobic ratio at 49.9%, protein-binding potential (Boman index) of 2.17 kcal/mol, and hydrophobicity of + 13.67 kcal/mol. Furthermore, MIC and MBC values of the extract and the < 10 kDa fraction on both bacteria ranged from 0.50-1.03 mg/ml. The GSS meat extract could reach the intracellular site of while in it was localized in the cell membrane. These results can be baseline information for developing AMPs in natural bio-preservative exploration as food additives and pharmaceuticals.

Antimicrobial peptides (AMPs) have emerged as potential alternatives to conventional antibiotics due to their novelty and multiple mechanisms of action. Because they are peptides, AMPs are amenable to bioengineering and suitable for cloning and expression at large production scales. However, the efficient delivery of AMPs is an unaddressed issue, particularly due to their large size, possible toxicities, and the development of adverse immune responses.

The emergence and re-emergence of multi-drug-resistant (MDR) infectious diseases have once again posed a significant global health challenge, largely attributed to the development of bacterial resistance to conventional anti-microbial treatments. To mitigate the risk of drug resistance globally, both antibiotics and immunotherapy are essential. Antimicrobial peptides (AMPs), also referred to as host defense peptides (HDPs), present a promising therapeutic alternative for treating drug-resistant infections due to their various mechanisms of action, which encompass antimicrobial and immunomodulatory effects.

Unlabelled: We have developed novel and sustainable homogeneous catalysts employing Glutamic acid (Glu) as a biodegradable and eco-friendly organocatalyst for the synthesis of -(4-oxo-2-phenyl-1,2-dihydroquinazolin-3(4)-yl)isonicotinamide derivatives (-) via multicomponent reactions (MCRs) of isatoic anhydride, isoniazid and heteroaromatic/aromatic aldehyde in ethanol on oil bath stirring at 60 °C. Selected final product homogeneity was examined by various spectroscopic techniques such as C-, H- NMR, FT-IR and LC-MS. For the first time, herein investigated electrochemical behavior of selected derivatives (-) using cyclic voltammetry method.

Antimicrobial peptides (AMPs) are crucial components of the innate immune system in all living organisms, playing a vital role in the body's defense against diseases and infections. The immune system's primary functions include preventing disease-causing agents from entering the body and eliminating them without causing harm. These peptides exhibit broad-spectrum activity against bacteria, viruses, fungi, parasites, and cancer cells.
