Indole-chalcone hybrids have burst into prominence as potent weapons in the battle against pain and inflammation due to their unique features, allowing these ligands to form pivotal interactions with biological targets. In this context, the base-catalyzed Claisen-Schmidt condensation of 3',4'-(methylenedioxy)acetophenone with heteroaromatic aldehydes carrying an indole scaffold yielded new chalcones (1-7). The central and peripheral ...

Tetrodotoxin (TTX) was identified as a latent neurotoxin that has a significant analgesia effect. It was rapidly absorbed and excreted in rat after intramuscular (i.m.) injection. To maintain the effect, frequent injections were required. The enteric sustained-release TTX pellets with sucrose pellets as a drug carrier was prepared by fluidized bed spray irrigation, coated in sequence with Eudragit NE30D as a sustained-release layer, ...

The presence of food affects many aspects of behavior. In vertebrates, the neuropeptide cholecystokinin (CCK) acts as a satiety modulator in the brain and regulates digestion in the intestine. Vertebrate CCK is also involved in the regulation of gastrointestinal motility as well as in the regulation of various behaviors including anxiety, nociception, analgesia, memory and dopamine-related behaviors. As a consequence CCK can also be involved in ...

Early life stress results in an enduring vulnerability to kindling-induced epileptogenesis in rats, but the underlying mechanisms are not well understood. Recent studies indicate the involvement of thalamocortical neuronal circuits in the progression of kindling epileptogenesis. Therefore, we sought to determine in vivo the effects of early life stress and amygdala kindling on the firing pattern of hippocampus as well as thalamic and cortical ...

More and more orthopedic procedures are performed in an outpatient setting. A commonly used strategy in pain management is the intra-articular injection of local anesthetics. Recent attention has been drawn to their possible toxic effect on chondrocytes. Local anesthetics, and in particular Lidocaine, are also used for diagnostic joint infiltrations. A controlled laboratory study was performed to investigate the possible toxic effect of ...

Breast cancer is the most common female cancer comprising about 25% of all worldwide cases. Particularly in Belgium, breast cancer and its sequelae are a clinically significant problem. Belgium has both the highest incidence rate of female breast cancer as well as the highest rate of breast cancer survivors. The treatment of breast cancer is multidisciplinary and involves surgical –, radiation – and medical oncology treatment. For the majority ...

α7 Nicotinic acetylcholine receptors (nAChRs) are ion channels implicated in a number of CNS pathological processes, including pain and psychiatric, cognitive and inflammatory diseases. Comparing with orthosteric agonism, positive allosteric modulation of these channels constitutes an interesting approach to achieve selectivity versus other nicotinic receptors. We have recently described new chalcones and 1,3-diphenylpropanones as positive ...
