AI Article Synopsis

  • A new conjugate combining artesunate and podophyllotoxin was developed and tested for its effectiveness against various cancer cell lines using a CCK-8 assay.
  • It demonstrated strong cytotoxic effects with IC50 values ranging from 0.453 to 3.011 μM, and helped reduce drug resistance in the cells.
  • Additional findings showed that the conjugate disrupts microtubules, triggers G2/M cell cycle arrest, induces cancer cell death through apoptosis, and lowers levels of P-glycoprotein in resistant cancer cells.

Article Abstract

A novel conjugate of artesunate-podophyllotoxin was prepared and evaluated for its cytotoxicity against diverse normal and multidrug resistance human cancer cell lines by CCK-8 assay. The conjugate exhibited good cytotoxicity on all the cell lines with IC50 values of 0.453±0.156-3.011±0.272μM and reduced the resistant factor. The conjugate was further found to disrupt the microtubule network and induce G2/M cell cycle arrest in multidrug resistance K562/ADR cells. Meanwhile, Hoechst staining analysis suggested that conjugate induced cell death by apoptosis. Furthermore, conjugate could downregulate the levels of P-glycoprotein (P-gp) in P-gp overexpressing K562/ADR cells.

Introduction: In the pediatric setting, overprescribing of antibiotics contributes to the rise of multidrug-resistant organisms. Antimicrobial stewardship programs (ASPs) are recommended to optimize antibiotic use and combat resistance. However, the implementation of ASPs in low- and middle-income countries faces several challenges.

Purpose Of The Review: This review aims to explore the pivotal role of long non-coding RNAs (lncRNAs) as epigenetic regulators in the pathogenesis of multiple myeloma (MM). Additionally, we have portrayed the dual role of lncRNAs in the epigenetic landscape of MM pathobiology.

Recent Findings: In MM, lncRNAs are pivotal for proliferation, progression, and drug resistance by acting as miRNA sponges, regulating mRNA activity through microRNA recognition elements (MREs).

This review delves into the potential of antimicrobial peptides (AMPs) as promising candidates for combating arboviruses, focusing on their mechanisms of antiviral activity, challenges, and future directions. AMPs have shown promise in preventing arbovirus attachment to host cells, inducing interferon production, and targeting multiple viral stages, illustrating their multifaceted impact on arbovirus infections. Structural elucidation of AMP-viral complexes is explored to deepen the understanding of molecular determinants governing viral neutralization, paving the way for structure-guided design.

A Novel Isotropic Optical Fiber: Antimicrobial Effect of Blue Light on Drug Resistant Organisms.

J Orthop Res

January 2025

Department of Orthopaedic Surgery, Division of Arthroplasty and Joint Reconstruction, Brigham and Women's Hospital, Harvard Medical School, Boston, Massachusetts, USA.

Drug-resistant organisms (DROs) necessitate the development of new therapies. Antimicrobial blue light (ABL) is a promising option, utilizing photoexcitation of endogenous bacterial components to generate reactive oxygen species, leading to bacterial death. The aim of this study is to investigate the effects of a novel isotropic optical fiber under in-vitro conditions on multidrug-resistant gram-negative Pseudomonas aeruginosa (MDR-Pa) and methicillin-resistant Staphylococcus aureus (MRSA).
