This volume focuses on the transport of medically relevant bacterial protein toxins into mammalian cells, and on novel pharmacological strategies to inhibit toxin uptake. The first chapters review our current understanding of the cell-surface receptors and cellular transport processes of Clostridium botulinum neurotoxins, Clostridium botulinum C3 toxin, Clostridium difficile toxins, binary clostridial enterotoxins, anthrax toxins and diphtheria toxin.

In addition, their inhibitory activity on NO production and cytotoxic effects against human embryonic kidney cells (HEK-293A) and human hepatocellular carcinoma (HepG2) were evaluated. This is the first study of the phytochemical investigation of P. ginseng sprouts cultivated in Vietnam and ginseng sprouts also contained the same main active ginsenosides as in the 4–6-year old roots.

The methanol extracts as well as some compounds from this plant exhibited anti-inflammatory, antimicrobial activity, antioxidant, hepatoprotective and anti-cancer effect, and antiosteoporotic. On going to search for bioactive components from the Vietnamese plant, this paper reported the isolation of seven phenolic compounds including one new from the aerial parts of A. ilicifolius. The cytotoxic activity of the isolates against two cancer cell lines (HepG2 and SK-LU1) were also screened and reported herein.

This compound converted to Mannich base which interne illustrated as tridentate ligand of NO2-type. Meanwhile, the organic synthesis of the compounds is not an easy task, especially lactonization; hint naphthafuran-2-one has never been prepared from amino nitrile previously. Selected metal ions of known anticancer activity interacted with the ligand to present novel complexes to figure out the cytotoxicity effect of both organic and inorganic parts against cancer cell line.

While immune checkpoint inhibitors (ICIs) occasionally cause immune-related adverse events (irAEs) in various organs, the prevalence of irAEs and potential risk factors have not been clarified. We identified irAE predictive factors and examined the relationship between the effect of ICIs and irAEs for patients with malignancies.

Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) combined with cytotoxic chemotherapy are highly effective in the treatment of advanced non–small-cell lung cancer (NSCLC) with EGFR mutations. The purpose of this study is to evaluate the efcacy and safety of this combination in advanced NSCLC patients with an EGFR/TP53 co-mutation.

Cancer therapy has evolved from non-specific cytotoxic agents to a selective, mechanism-based approach that includes targeted agents and immunotherapy. Although the response to targeted therapies for unresectable hepatocellular carcinoma (HCC) is acceptable with the improved survival, the high tumor recurrence rate and drug-related side effects continue to be problematic.

Drug resistance is a major cause of the inefficacy of conventional cancer therapies, and often accompanied by severe side effects. Thus, there is an urgent need to develop novel drugs with low cytotoxicity, high selectivity and mini‑ mal acquired chemical resistance.

In this study, anticholinergic, antidiabetic, antioxidant and cytotoxic activities of Reseda lutea L. (R. lutea) were determined. Ethanol extracts of R. lutea (EERL) and water extract of R. lutea (WERL) were prepared for biochemical analysis. The antioxidant capacities of EERL and WERL were evaluated with 6 different methods. In addition, acetylcholinesterase (AChE), α-amylase and α-glycosidase enzyme inhibition by EERL were measured.

Onosma L., the largest genus of Boraginaceae, is represented by 105 species in Turkey with an endemism rate of 52%. Phytochemical studies indicate that Boraginaceae plants mainly comprise naphthoquinones with a wide range of biological activities including anticancer, antiinflammatory, wound healing, and antioxidant effects. However, few taxa of the genus Onosma have been investigated in detail for their bioactivities.

The present study investigated the modulation of autophagy and its impact on the cytotoxicity of AraC toward murine myelogenous leukemia cells (M-NFS-60). Autophagy was inhibited by NH4 Cl or Bafilomycin A1 or enhanced by amino acid starvation, glucose starvation, mild hyperthermia (41 °C), or rapamycin (Rap). Cells were treated with different concentrations, 0 to 2 µM, of AraC in the presence or absence of autophagy modulators.

The acute toxicity, cytotoxicity, genotoxicity and antigenotoxic effects of BC were studied. Cytotoxicity of BC was evaluated in cultured C3A hepatoma cells (HepG2/C3A) using a lactate dehydrogenase (LDH) activity assay. Acute toxicity was tested in adults Wistar rats treated with a single dose of BC.

Surfactants have been used as a tool to improve the properties of polymeric nanoparticles (NPs) and to increase the rate of hydrophobic drug release by means of these nanoparticles. In this context, this study evaluated the effect of lecithin on the characteristics of chitosan (CHI) and chondroitin sulfate (CS) nanoparticles, when applied in curcumin (Curc) release.

We report herein a new chemical platform for coupling chitosan derivatives to antimicrobial peptide dendrimers (AMPDs) with different degrees of ramification and molecular weights via thiol-maleimide reactions. Previous studies showed that simple incorporation of AMPDs to polymeric hydrogels resulted in a loss of antibacterial activity and augmented cytotoxicity to mammalian cells.

Anti-androgens entering the aquatic environment, e.g., by effluents from wastewater treatment plants or agricultural settings are contributing to endocrine disruption in wildlife and humans. Due to the simultaneous presence of agonistic compounds, common in vitro bioassays can underestimate the risk posed by androgen antagonists.

Chalcones are a class of compounds with a wide range of biological activities. In addition, derivatives based on the quinazolinone skeleton are currently of interest to research in the screening of compounds with cytotoxic effects. Compounds containing chalcone structures on the basis of quinazolinone can yield new structures with cytotoxic effects.
