Synthesis and herbicidal activity of 5-(haloalkyl)-substituted thiazolo[4,5-b]pyridine-3(2H)-acetic acid derivatives

Synthesis of chitosan‐graft‐poly[2‐cyano‐1‐(pyridin‐3‐yl)allyl acrylate] copolymer from a novel monomer, prepared using a Morita–Baylis–Hillman reaction, and characterization of its antimicrobial activity

“…Pyridines are an important class of nitrogen heterocycles that possess a broad range of biological activities, such as fungicidal, insecticidal and herbicidal activities . As a consequence of these biological properties, the effects of chitosan graft copolymers on selected microorganisms (bacteria: Bacillus subtilis , Escherichia coli ; fungi: Aspergillus niger , Penicillium digitatum , Staphylococcus aureus ) were studied (Table ).…”

Anti-inflammatory properties of some novel thiazolo[4,5-b]pyridin-2-ones

“…Thiazolidone derivatives anelated with the pyridine cycle, in particular thiazolopyridine, are of particular interest to researchers because these compounds exhibit different types of biological activity. Among them were identified substances with antioxidant (Chaban et al 2013(Chaban et al , 2019aKlenina et al 2013Klenina et al , 2017, fungicidal (Marzoog and Al-Thebeiti 2000), anti-inflammatory (Chaban et al 2016(Chaban et al , 2017b(Chaban et al , 2018b, anti-mitotic (Victor et al 2017), tuberculostatic (Chaban et al 2014), herbicidal (Hegde and Mahoney 1993) and antitumor (Chaban et al 2012a) activities, agonists of H3-histamine receptors (Walczyn´ski et al 2005), antagonists of metabotropic glutamate receptors 5 (mGluR5) (Lin et al 2009), substances with high inhibitory activity against epidermal growth factor receptors (Komoriya et al 2006) and several other enzymes (Singh et al 1995). Given the above synthesis of new thiazolopyridines, as well as the pharmacological screening of the anti-inflammatory activity of the newly synthesized compounds is an interesting and relevant direction.…”

Synthesis and antibacterial activity against ralstonia solanacearum for novel hydrazone derivatives containing a pyridine moiety

“…Pyridine is an important class of heterocyclic ring, which have been attracted more and more attention in the pesticides areas due to their broad-activities, such as fungicidal activity [ 6 - 8 ], insecticidal activity [ 9 , 10 ] and herbicidal activity [ 11 , 12 ]. In fungicidal activity regard, some pyridine derivatives can prevent Erysiphe graminis , Botrytis cinerea [ 13 ], Pyricularia oryzae [ 14 ] and Phytophthora infestans [ 15 ].…”
