The synthesis and anticonvulsant properties of new 1-(2-pyridinyl)- succinimides [I-XXII] differently substituted at the position-3 of imide ring have been described. The profile of pharmacological activity of these compounds was examined by a maximal electroshock (MES) and pentylenetetrazole (scPTZ) tests, whereas their neurotoxicity was determined using a rotarod screen. The results obtained ...
Inhibition of angiogenesis is considered as one of the desirable pathways for the treatment of tumor growth and metastasis. Herein we demonstrated that a series of pyridinyl-thiazolyl carboxamide derivatives were designed, synthesized and examined against angiogenesis through a colony formation and migration assays of human umbilical vein endothelial cells (HUVECs) in vitro. A structure-activit...
Palladium complexes containing 2,7-bis(mesitylimidazolylidenyl)naphthyridine (NHC-NP) have been synthesized and characterized. Reaction of [{Ag(3)(NHC-NP)(2)}(PF(6))(3)] with [Pd(PhCN)(2)Cl(2)] provided an unusual dipalladium complex bridged by two NHC-NP units, forming a 20-membered dinuclear metallacycle [{Pd(2)(NHC-NP)(2)Cl(2)}(PF(6))] (2) in high yield. Treatment of 2 with KI in acetone yie...
During inflammation, immune cells activated by toll-like receptors (TLRs) have the ability to undergo a bioenergetic switch towards glycolysis in a manner similar to that observed in tumour cells. While TLRs have been implicated in the pathogenesis of rheumatoid arthritis (RA), their role in regulating cellular metabolism in synovial cells, however, is still unknown. In this study, we investiga...
KRAS is the most commonly altered oncogene of RAS family, especially G12C mutant (KRASG12C), which has been a promising drug target for many cancers. On basis bicyclic pyridopyrimidinone framework first-in-class clinical KRASG12C inhibitor AMG510, scaffold hopping strategy was conducted including F–OH cyclization approach and pyridinyl N-atom working leading to new tetracyclic analogues. Compou...
Direct intramolecular cation-pi interaction between phenyl and pyridinium moieties in 1a(+) has been experimentally evidenced through pH-dependent (1)H NMR titration. The basicity of the pyridinyl group (pK(a) 2.9) in 1a can be measured both from the pH-dependent chemical shifts of the pyridinyl protons as well as from the protons of the neighboring phenyl and methyl groups as a result of elect...
