We have previously described the potent and selective (RS)-2-amino-3-(3- hydroxy-5-methyl-4-isoxazolyl)propionic acid (AMPA) receptor agonist, (RS)-2- amino-3-(3-carboxy-5-methyl-4-isoxazolyl)propionic acid (ACPA), and the AMPA receptor antagonist (RS)-2-amino-3-[3-(carboxymethoxy)-5-methyl-4- isoxazolyl]propionic acid (AMOA). Using these AMPA receptor ligands as leads, a series of compounds have been developed as tools for further elucidation of the structural requirements for activation and blockade of AMPA receptors. The synthesized compounds have been tested for activity at ionotropic excitatory amino acid (EAA) receptors using receptor binding and electrophysiological techniques, and for activity at metabotropic EAA receptors using second messenger assays. Compounds 1 and 4 were essentially inactive. (RS)-2-Amino-3-[3-(2-carboxyethyl)-5-methyl-4-isoxazolyl]propionic acid (ACMP, 2), on the other hand, was shown to be a selective AMPA receptor antagonist (IC50 = 73 muM), more potent in electrophysiological experiments than AMOA (IC50 = 320 muM). The isomeric analogue of 2, compound 5, did not show AMPA antagonist effects, but was a weak NMDA receptor antagonist (IC50 = 540 muM). Finally, compound 3, which is an isomer of ACPA, turned out to be a very weak NMDA antagonist, and an AMPA receptor agonist approximately 1 000 times weaker than ACPA. None of the compounds showed agonist or antagonist effects at metabotropic EAA receptors. (C) 2000 Editions scientifiques et medicales Elsevier SAS.

Silicon amine protocol (SLAP) reagents for photocatalytic cross-coupling with aldehydes and ketones to form N-unprotected piperazines have been developed. This blue light promoted process tolerates a wide range of heteroaromatic, aromatic, and aliphatic aldehydes and structurally and stereochemically complex SLAP reagents. It provides a tin-free alternative to SnAP (tin amine protocol) reagents for the synthesis of substituted piperazines.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.name: 5-Methylisoxazole-3-carboxaldehyde, you can also check out more blogs about62254-74-4

Pergularia daemia is a hispid perennial herb, its latex used in traditional ayurvedic and siddha medicine for migraine, head ache, muscle sprain and swelling sores, boils. Despite of its pain relieving potential, the mechanisms of these effects have yet to be elucidated. The methanolic flavonoids rich Pergularia daemia latex (PDL) extract subjected into particular peripheral and central antinociceptive effects in laboratory animals. The present study was to determine the involvement of nitric oxide (NO)/cyclic guanosine monophosphate (cGMP)/ potassium (K+) channels pathway in the peripheral antinociception induced by flavonoids rich PDL. It was executed systemically for (50, 100 and 200 mg/kg p.o.) to generate dose dependent antinociception when evaluated using acetic acid induced abdominal writhing and formalin test with measured mean IC50 value of 169.9 mg/kg, 136.6 mg/kg and 174.8 mg/kg respectively. PDL at similar doses showed significant dose dependent inhibition of neurogenic pain induced by capsaicin (1.6 g/paw/ IC50 = 194.9 mg/kg) and glutamate (10 mumol/paw/ IC50 = 204.6 mg/kg) which elicits the participation of vanilloid (TRPV) receptors and glutamatergic system. Moreover, PDL displayed reversed antinociception with L-arginine (a NO precursor) (100 mg/kg, s.c.), implying the involvement of L-arginine/nitric oxide pathway besides methylene blue (10 mg/kg, s.c.) remarkably increased the antinociception and an ATP-sensitive K+ channel antagonist glibenclamide (10 mg/kg, i.p.) reversed antinociceptive activity when administered systemically induced by PDL. Conjointly, the results suggested that PDL induced antinociceptive activity was possibly related to inactivate TRPV receptor, glutamatergic system along with the activation of NO/cGMP/ATP sensitive K+ channel pathway.
