The Efficacy of Cecropin Against Multidrug-Resistant Bacteria Is Linked to the Destabilization of Outer Membrane Structure LPS of Gram-Negative Bacteria.

The escalating prevalence of antibiotic-resistant bacteria has emerged as a formidable threat to global health, and the quest for alternative antimicrobial agents is imperative. Cecropins, a class of antimicrobial peptides (AMPs), have garnered attention due to their potent bactericidal properties. This investigation delves into the antibacterial prowess of Cecropin A (CA) and Cecropin AD (CAD), showcasing their robust activity against Gram-negative bacteria, inclusive of multidrug-resistant bacteria.

Insights into forsythia honeysuckle (Lianhuaqingwen) capsules: A Chinese herbal medicine repurposed for COVID-19 pandemic.

Background: In December 2019, a novel coronavirus, SARS-CoV-2 caused a series of acute atypical respiratory diseases worldwide. However, there is still a lack of drugs with clear curative effects, and the clinical trial research of vaccines has not been completely finished.

Mechanism of Infantile Feire Kechuan Oral Solution against Mycoplasma pneumoniae infection of A549 cells.

Background: Mycoplasma pneumoniae is a leading cause of community-acquired respiratory infections. Infantile Feire Kechuan Oral Solution (IFKOS) is effective for treatment of M. pneumoniae infection.

RNA-dependent RNA polymerase (RdRp) inhibitors: The current landscape and repurposing for the COVID-19 pandemic.

The widespread nature of several viruses is greatly credited to their rapidly altering RNA genomes that enable the infection to persist despite challenges presented by host cells. Within the RNA genome of infections is RNA-dependent RNA polymerase (RdRp), which is an essential enzyme that helps in RNA synthesis by catalysing the RNA template-dependent development of phosphodiester bonds. Therefore, RdRp is an important therapeutic target in RNA virus-caused diseases, including SARS-CoV-2.

The development of Bruton's tyrosine kinase (BTK) inhibitors from 2012 to 2017: A mini-review.

Bruton's tyrosine kinase (BTK) has emerged as a promising drug target for multiple diseases, particularly haematopoietic malignancies and autoimmune diseases related to B lymphocytes. This review focuses on the diverse, small-molecule inhibitors of BTK kinase that have shown good prospects for clinical application. Individual examples of these inhibitors, including both reversible and irreversible inhibitors and a recently developed reversible covalent inhibitor of BTK, are discussed.

Synthesis and in vitro and in vivo antitumour activity study of 11-hydroxyl esterified bergenin/cinnamic acid hybrids.

Fourteen bergenin/cinnamic acid hybrids were synthesized, characterized and evaluated for their antitumour activity both in vitro and in vivo. The most potent compound, 5c, arrested HepG2 cells (IC = 4.23 ± 0.
