A computational lead-hopping exercise identified compound 4 as a structurally distinct P2X(7) receptor antagonist. Structure-activity relationships (SAR) of a series of pyroglutamic acid amide analogues of 4 were investigated and compound 31 was identified as a potent P2X(7) antagonist with excellent in vivo activity in animal models of pain, and a profile suitable for progression to clinical studies.

Soils harbor some of the most diverse microbiomes on Earth. Interactions within these microbial communities are often mediated by natural products, many functioning as chemical signals. Specialized metabolites known as arginoketides, or arginine-derived polyketides, have been linked to mediate these interactions.

Through applying the hybridization technique, new coumarin derivatives (2-17) were prepared with substitution at coumarin C-3 utilizing various heterocyclic derivatives, aiming to afford multi-target carbonic anhydrases (CAs) IX/XII and topoisomerase II (Topo II) inhibitors with potent antiproliferative activity. Eight different cell lines were used to evaluate the growth inhibition percentages (GI%) of cancer cells determined by coumarin analogues 1-17. Analogues 16 and 17 had the most substantial cytotoxic effects, achieving mean GI% of 86.

The design of efficient and user-friendly methods for nitrite detection is of great significance owing to its critical role in food safety and environmental protection. Herein, we report a novel cobalt single-atom nanozyme (CoN SA) featuring a highly asymmetric CoN coordination environment. This structural configuration stabilizes high-spin Co species and significantly enhances the oxidase-like activity.

The ryanodine receptors (RyRs) represent an optimal target for insecticide development. To explore novel structures of RyRs agonists, a series of compounds containing 1,2,4-oxadiazole were designed and synthesized based on the RyRs structure. The compounds were confirmed by H and C nuclear magnetic resonance as well as high-resolution mass spectrometry.

In this review, the primary aim is to examine non-azole ring systems that have analgesic activity and, where applicable, to establish structure - activity relationships (SARs) with the nine major pathways, prostaglandin synthesis inhibition, opioid receptor modulation, sodium channel blockade, enhancement of serotonin and norepinephrine levels, cannabinoid receptor (CBR) binding, N-methyl-D-aspartate (NMDA) receptor antagonism, transient receptor potential cation channel subfamily V member 1 (TRPV1) antagonism, and P2X purinergic receptor blockade, have been described for pain relief. Analgesic effects have been observed in compounds containing ring systems such as piperidine, piperazine, pyridine, pyridazine, pyrazine, morpholine, thiomorpholine, pyran, thiopyran, indane, benzofuran, benzothiophene, quinoline, quinazoline, and chromene. These ring systems were classified in the whole study, first according to their molecular weights and then by bioisosteric similarity as same as first part.
