Synthetic Route of 68206-04-2, In chemical reaction engineering, simulations are useful for investigating and optimizing a particular reaction process or system. In a article, 68206-04-2, molcular formula is C5H5ClN2, introducing its new discovery.

We have recently shown that an aryloaminopyridazine derivarive of GABA, SR 95103 <2-(3-carboxypropyl)-3-amino-4-methyl-6-phenylpyridazinium chloride>, is a selective and competitive GABA-A receptor antagonist.In order to further explore the structural requirements for GABA receptor affinity, we synthesized a series of 38 compounds by attaching various pyridazinic structures to GABA or GABA-like side chains.Most of the compounds displaced <3H>GABA from rat brain membranes.All the active compounds antagonized the GABA-elicited enhancement of <3H>diazepam binding, strongly suggesting that all these compounds are GABA-A receptor antagonists.None of the compounds that displaced <3H>GABA from rat brain membranes interacted with other GABA recognition sites (GABA-B receptor, GABA uptake binding site, glutamate decarboxylase, GABA-transaminase).They did not interact with the Cl- ionophore associated with the GABA-A receptor and did not interact with the benzodiazepine, strychnine, and glutamate binding sites.Thus these compounds appear to be specific GABA-A receptor antagonists.In terms of structure-activity, it can be concluded that a GABA moiety bearing a positive charge is necessary for optimal GABA-A receptor recognition.Additional binding sites are tolerated only if they are part of a charge-delocalized amidinic or guanidinic system.If this delocalization is achieved by linking a butyric acid moiety to the N(2) nitrogen of a 3-aminopyridazine, GABA-antagonistic character is produced.The highest potency (ca.250 times bicuculline) was observed when an aromatic ? system, bearing electron-donating substituents, was present on the 6-position of the pyridazine ring.

In the meantime we’ve collected together some recent articles in this area about 68206-04-2 to whet your appetite. Happy reading! Synthetic Route of 68206-04-2

A series of pyridazinylpiperazines were synthesized and evaluated for VR1 antagonist activity in order to improve upon the pharmaceutical and pharmacological properties of BCTC. A structurally biased chemical library of pyridazinylpiperazine analogs was prepared in an effort to improve the pharmaceutical and pharmacological profile of the lead compound N-(4-tertiarybutylphenyl)-4-(3-chloropyridin-2-yl)tetrahydropyrazine-1(2H) -carboxamide (BCTC). The library was evaluated for VR1 antagonist activity in capsaicin-induced (CAP) and pH 5.5-induced (pH) FLIPR assays in a human VR1-expressing HEK293 cell line. The most potent VR1 antagonists were found to have IC50 values in the range of 9-200 nM with improved pharmaceutical and pharmacological profiles versus the lead BCTC. These compounds represent possible second-generation BCTC analogs.
