AI Article Synopsis

  • The study identified cytotoxic compounds, falcarinol and falcarindiol, from the roots of Glehnia littoralis, effective against both sensitive and resistant colorectal and lung cancer cells.
  • Researchers isolated 13 polyacetylenes, including a new compound (3R,11R)-11-hyroxy-isofalcarinolone, using advanced chemical analysis techniques.
  • Findings suggest that while these compounds show potential for anticancer development, their stability needs further investigation since some newly purified compounds did not exhibit expected activity.

Article Abstract

In the preliminary screening, falcarinol and falcarindiol, C polyacetylenes from the roots of Glehnia littoralis F. Schmidt ex Miq (Umbelliferae), displayed cytotoxic activity both against oxaliplatin-sensitive/resistant colorectal cancer (CRC) and gefitinib-sensitive/resistant non-small cell lung cancer (NSCLC) cells. In this study, 13 polyacetylenes including a new (3R,11R)-11-hyroxy-isofalcarinolone (1) were isolated from G. littoralis, and the chemical structures were elucidated through NMR, HRMS, and optical rotation analysis as well as DP4 plus calculation. (3S,8S)-Oplopandiol (5) showed cytotoxic activities against oxaliplatin-sensitive and -resistant CRC (HCT116 and HCT116-OxR) cells. Unexpectedly, (3R,8S)-falcarindiol (3) and (3S)-falcarinol (12), newly purified from G. littoralis, did not show cytotoxic activity. It was confirmed that both falcarinol and falcarindiol, previously evaluated, were decomposed, which seems to be the cause of inconsistent biological results. These findings indicated that C polyacetylene could be a good starting compound for the development of anticancer leads against drug-resistant CRC and NSCLC cells, however, the stability of C polyacetylens should be considered for further studies.

Introduction: Although photodynamic therapy (PDT) shows considerable potential for cancer treatment due to its precise spatial control and reduced toxicity, effectively eliminating residual cells under hypoxic conditions remains challenging because of the resistance conferred by these cells.

Methods: Herein, we synthesize an amphiphilic PEGylated polyphosphoester and present a nanocarrier (NP) specifically designed for the codelivery of hydrophobic photosensitizer (chlorin e6, Ce6) and hypoxia-activated prodrugs (tirapazamine, TPZ). We investigate the antitumor effect of NP on both cellular and animal level.

Despite the fact that life expectancies are increasing and the burden of infectious diseases is decreasing, global cancer incidence rates are on the rise. Cancer outcome metrics are dismal for low- and middle-income countries (LMICs), including sub-Saharan Africa, where adequate resources and infrastructure for cancer care and control are lacking. Nigeria, the most populous country in Africa, exemplifies the miserable situation.

The neuropeptide oxytocin (OXT) and its receptor (OXTR) have been shown to play an important role in glucose metabolism, and pancreatic islets express this ligand and receptor. In the current study, OXTR expression was identified in α-, β-, and δ-cells of the pancreatic islet by RNA hybridization, and OXT protein expression was observed only in β-cells. In order to examine the contribution of islet OXT/OXTR in glycemic control and islet β-cell heath, we developed a β-cell specific OXTR knock-out (β-KO) mouse.
