Self-Immolative Systems in Diagnostic and Therapeutic Applications
Windbedema Prisca Ouédraogo, Thomas Cailly, Valérie Collot
Self-immolative systems first emerged in prodrug chemistry in the 1980s. Since then, several types of self-immolative systems have been developed. Despite their structural differences, all self-immolative systems operate on the same principle: an intramolecular reaction cascade triggered by a specific stimulus, ultimately leading to the releas(...)

Study of phenolic compounds of Phyllanthus amarus and their α-glucosidase enzyme inhibitory activity assessment
Ousmane Ilboudo, Têeda Hamidou Ganamé, Wende-konté Hazaël Conania Nikiéma, Tegwendé Tibnongdo Zabré, Yssouf Karanga and Issa Tapsoba
The access to diabetes care remains limited in low-income countries, leading populations to rely on
medicinal plants. In Burkina Faso, Phyllanthus amarus is traditionally used against diabetes. This study
aimed to identify its chemical constituents and evaluate the antidiabetic potential of aqueous,
hydroethanolic, and decocted extracts fro(...)

Synthesis and Spectrometric Study of New Iron Phthalocyanine Polymers: Influence of Peripheral COOH and CN Groups on Vibrational and Electronic Properties
Lassané Tarpaga, Aristide W G Nitiema, Seydou Ouédraogo, Bertrand Ouemega, Bintou Sessouma, Mabinty Bayo-Bangoura, Karifa Bayo
We have prepared and isolated in solid form two types of polymers formed between iron (II) complexes ([FePc(COOH)8] and [FePc(CN)8]) and two bidentate ligands [trans-1,2-bis (4-pyridyl) ethylene (bpe); trans-1,2-bis (4-pyridyl) ethane (bpa)]. The electronic and vibrational absorption spectra of these complexes are discussed in comparison with(...)

Characterization of Local Clay from Burkina Faso for the Removal of Lead from Groundwater
Arzouma Christophe Guissou, Dimanche Regie Ouedraogo, Brahima Sorgho*, Yacouba Soutra
The contamination of water resources by trace metals (TMs), particularly lead
(Pb2+), is a significant public health and environmental concern, especially in
areas where access to modern treatment technologies is limited. The adsorbent
material used is KOM clay, collected from Kombissiri, near Ouagadougou, in
Burkina Faso, and characte(...)

Application d’un biotraitement membranaire à l’abattement de la teneur en micropolluants d’une eau usée synthétique
Jean de Dieu Zongo, Yacouba Sanou
Les effluents des stations d'épuration contiennent des polluants organiques, inorganiques et microbiens, représentant une source majeure de contamination des eaux et des sols. Ce travail vise à étudier le biotraitement des eaux usées en vue d’éliminer le bisphénol A (BPA), la demande chimique en oxygène (DCO), l’ammonium (NH4+) et les ortho-ph(...)

Influence of anodizing processes on corrosion performance of AA5005 aluminium alloy
Ramdé Tambi
To investigate the effects of anodizing processes on the corrosion performance of alloy AA5005, a series of electrochemical and salt spray tests was conducted. Test results showed that the corrosion performance of anodized AA5005 depends both on anodizing time and the sealing process. Scanning electron microscopic (SEM) examination revealed mu(...)
