“…The in vivo toxicity of tetrapyridylporphyrin containing four chloro(2,2′-bipyridine)platinum(II) complex (3-H 2 TPtPyP) ( 3.1–3.4 ) attached at the meta position of the peripheral pyridine ligand was tested at 0.6–5.5 μΜ (Table 1 ). The sample shows no in vivo toxicity since the %MIA is almost 100 at the highest concentration ( 3.4 ), which is in consistent with the % root length [ 24 ].…”

Assessment of the biological effect of metal ions and their complexes using Allium cepa and Artemia salina assays: a possible environmental implementation of biological inorganic chemistry

The pollution of aquatic ecosystems due to the elevated concentration of a variety of contaminants, such as metal ions, poses a threat to humankind, as these ecosystems are in high relevance with human activities and survivability. The exposure in heavy metal ions is responsible for many severe chronic and pathogenic diseases and some types of cancer as well. Metal ions of the groups 11 (Cu, Ag, Au), 12 (Zn, Cd, Hg), 14 (Sn, Pb) and 15 (Sb, Bi) highly interfere with proteins leading to DNA damage and oxidative stress. While, the detection of these contaminants is mainly based on physicochemical analysis, the chemical determination, however, is deemed ineffective in some cases because of their complex nature. The development of biological models for the evaluation of the presence of metal ions is an attractive solution, which provides more insights regarding their effects. The present work critically reviews the reports published regarding the toxicity assessment of heavy metal ions through Allium cepa and Artemia salina assays. The in vivo toxicity of the agents is not only dose depended, but it is also strongly affected by their ligand type. However, there is no comprehensive study which compares the biological effect of chemical agents against Allium cepa and Artemia salina. Reports that include metal ions and complexes interaction with either Allium cepa or Artemia salina bio-indicators are included in the review. Graphical abstract

“…To irradiate samples, a previously described light emitting diode (LED) device was used. 21 To assess the photostability of CPNs under blue light (450 nm) irradiation, absorbance and fluorescence spectra of the samples containing 20 mg mL À1 CN-PPV were measured prior to illumination (time 0) and after 30 and 60 minutes of light exposure at 27 mW cm À2 . Fourier transform infrared spectroscopy (FTIR) was used to further assess the structural changes induced by light exposure.…”

“…Silva et al [81] (Entry 15, table 2) evaluated the photolarvicidal activity of two meso-tetra (n-pyridyl) porphyrin derivatives (n = 3 or 4), the meso-tetra(platinated) isomers 3-PtTPyP and 4-PtTPyP). In this study, the larvae were incubated for 2 h in porphyrin derivatives prepared in aqueous solution and 1% DMSO in the concentration range of 1.2-12 ppm.…”

A look at photodynamic inactivation as a tool for pests and vector-borne diseases control

et al. 2022

The control of pests and vector-borne diseases (VDBs) are considered public health issues Worldwide. Among the control techniques and pesticides used so far, photodynamic inactivation (PDI) has been shown as an eco-friendly, low cost, and efficient approach to eliminate pests and VDBs. PDI is characterized using a photosensitizing molecule, light and molecular oxygen (O2) resulting in production of reactive oxidative species which can promote the oxidation of biomolecules on pests and vectors. Herein, we review the past 51 years (1970–2021) regarding the use of photo pesticides, reporting the most important parameters for the protocol applied, the results obtained, and limitations. Moreover, we described the mechanism of action of the PDI, main classes of photopesticides used so far as well as the cell death mechanism resulting from the photodynamic action.
