Summary: In this study, the sensitivity of peptide analysis and chromatographic behavior were compared between formic acid and acetic acid in reversed-phase liquid chromatography-tandem mass spectrometry (LC-MS/MS) applications. The results showed that acetic acid resulted in a 2.2-2.5 times increase in MS signal and a slight decrease in retention compared to formic acid. The number of identified peptides was up to 60% higher under acetic acid conditions, depending on the sample type. The retention shift was found to be dependent on peptide net charge and demonstrated the hydrophilicity of acetic acid.

Summary: The development of membrane-soluble antimicrobial peptides (AMPs) is urgently needed to address the problem of drug-resistant bacterial infections. However, issues such as poor biocompatibility, salt sensitivity, and proteolytic lability hinder their clinical use. In this study, a series of ultrashort stapled cyclization heptapeptides were created by inserting all-hydrocarbon staples. The most promising peptide, stRRL, demonstrated exceptional antibacterial activity and stability in high-protease and high-salt environments, making it a potential candidate to replace antibiotics for tackling bacterial infections.

Summary: NaBi(MoO4)(2) mesoporous material was successfully synthesized using a solvothermal method, and composites doped with Co3O4 and CuO were prepared. The average grain size of the nanoparticles was approximately 31 nm, and they exhibited a mesoporous structure. Co3O4 was uniformly distributed on the surface of NaBi(MoO4)(2) nanoparticles to form heterojunctions. The Co3O4-doped composite showed superior gas-sensitive properties compared to the pure NaBi(MoO4)(2) mesoporous material.

Summary: In this study, an anticancer AMP (Mastoparan) and its derivatives were designed and evaluated. Preliminary studies showed that the Mastoparan analogue KM8 exhibited selective antitumor effects but had metabolic instability. By substituting the 9Ala residue in KM8, a long-acting derivative KM8-Aib was generated, which showed higher metabolic stability, potent anticancer activity, and lower toxicity. Therefore, KM8-Aib is suggested as a potential antimalignant agent for further study.

Summary: The anti-cancer peptides show potential as new weapons for cancer therapy with potent toxicity against various cancer cells, but their promise is hindered by non-specific toxicity to normal cells. This study designed a sul-fonium tethered lytic peptide conjugated with a HDAC inhibitor to improve the selectivity towards cancer cells. The peptide showed reduced toxicity to both cancer cells and normal cells, and when conjugated with the HDAC inhibitor, it exhibited increased toxicity to cancer cells. The stabilized peptide HDAC conjugate also showed better serum stability and could induce cancer cell apoptosis, cell cycle arrest, and influence multiple signal pathways.

Summary: This study reports a Cu-catalyzed asymmetric cyclization reaction for the efficient synthesis of chiral 3-aminoindolines with high yield and enantioselectivity. The resulting products can undergo a radical-mediated sulfonyl migration to generate chiral 3-aminoindolines with alkenyl sulfonyl groups. Bioactivity evaluations demonstrate that these chiral 3-aminoindolines show notable antitumor activities and the chirality of the compounds plays a significant role in their antitumor activity.
