P176: Neurological Diseases: Causes, Symptoms and Treatments

The nervous system is an extremely complex communication system that can send and receive large amounts of information simultaneously. The nervous system has two distinct parts: the central nervous system (the brain and the spinal cord) and the peripheral nervous system (the nerves located outside the brain and spinal cord). The main unit of the nervous system is neural cells (neurons). The rou...

Ionotropic Glutamate Receptors and their Role in Neurological Diseases

Glutamate is extensively and relatively uniformly distributed in the central nervous system (CNS) and its effects mediated by two distinct groups of receptors including Ionotropic and metabotropic glutamate receptors. Concentration of glutamate in the nervous system is much higher than in other tissues. Glutamate receptors play an important role in synaptic transmission, neural plasticity and n...

The effects of Crocus sativus (saffron) and its constituents on nervous system: A review

Saffron or Crocus sativus L. (C. sativus) has been widely used as a medicinal plant to promote human health, especially in Asia. The main components of saffron are crocin, picrocrocin and safranal. The median lethal doses (LD50) of C. sativus are 200 mg/ml and 20.7 g/kg in vitro and in animal studies, respectively. Saffron has been suggested to be effective in the treatment of a wide range of d...

Directed functionalization of 1,2-dihydropyridines: stereoselective synthesis of 2,6-disubstituted piperidines.

A practical and highly stereoselective approach to access 2,6-disubstituted piperidines using an amidine auxiliary is reported. Following the diastereoselective addition of Grignard reagents at the 2-position of an activated pyridinium salt, the amidine group directs a regioselective metalation at the 6-position, enabling further functionalization. A subsequent electrophilic quench or a Negishi...
