Evaluation of the local anaesthetic activity of 3-aminobenzo[d]isothiazole derivatives using the rat sciatic nerve model

On the basis of computer prediction of biological activity by PASS and toxicity by DEREK, the most promising 32-alkylaminoacyl derivatives of 3-aminobenzo[d]isothiazole were selected for possible local anaesthetic action. This action was evaluated using an in vitro preparation of the isolated sciatic nerve of the rat and compared with lidocaine which was used as a reference compound. QSAR studies showed that the polarizability, polarity and molecular shape of molecules have a positive influence on their local anaesthetic activity, while contributions of aromatic CH and singly bonded nitrogen are negative. Since the estimated PASS probabilities to find local anaesthetic activity in the most active compounds are less than 50%, these compounds may be considered to be possible NCEs.

Synthesis and Structure of Esterification Products of 6-aryl-1,2,3,6,7,7a-hexahydro-3a,6-epoxyisoindole-7-carboxylic Acids

It was found that the reaction of 5-arylfurfurilamines with maleic anhydride leads to the formation of 6-aryl-3a,6-epoxyisoindole-7-carboxylic acids (the cyclic form), which in solution are in dynamic equilibrium with N-furfurylmaleinamides (the open form). During the esterification of these tautomeric mixtures with methanol in the presence of a catalytic amount of sulfuric acid, methyl esters of 5-aryl-7a-hydroxy-7-methoxy-3-oxo-2,3,3a,4,7,7a-hexahydro-1H-isoindole-4-carboxylic acids, unexpected cleavage products of the 3a,6-oxo bridge of the cyclic form, are formed diastereospecifically. The structure of the obtained products was confirmed by X-ray structural analysis.

NAPHTHOSULTAM DERIVATIVES – A NEW CLASS OF POTENT AND SELECTIVE 5-HT2 ANTAGONISTS

A series of 2-(aminoalkyl)naphth[1,8-cd]isothiazole 1,1-dioxides was synthesized and examined in various receptor binding tests. Most compounds demonstrated high affinity for the 5-HT2 receptor with moderate to high selectivity. A member of this series, compound 24 (RP 62203), displays high 5-HT2 receptor affinity (K(i) = 0.26 nM), which is respectively more than 100 and 1000 times higher than its affinity for alpha-1 (K(i) = 38 nM) and D2 (K(i) > 1000 nM) receptors. This compound is a potent orally effective and long lasting 5-HT2 antagonist in the mescaline-induced head-twitches test in mice and rats.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 29679-58-1, in my other articles.

NEGATIVE-ION FRAGMENTATIONS OF DEPROTONATED HETEROCYCLES – THE ISOTHIAZOLE, THIAZOLE, ISOXAZOLE, AND OXAZOLE RING-SYSTEMS

The major collision-induced dissociations of deprotonated isothiazole occur from the 5-anion, while deprotonated thiazole fragments almost equally through the 2- and 5-anions. Both 5-anions fragment by a simple retro cleavage yielding HC2S- and HCN. The 5-anion of isothiazole and the 2-anion of thiazole also rearrange to the common intermediate -SCH = CHCN which decomposes by losses of H-2, HCN and H2S, There is no evidence for direct interconversion of isothiazole and thiazole anions. The spectra of deprotonated methylisothiazoles and methylthiazoles are complex, but the major fragmentations are of ring deprotonated ions and are generally analogous to the parent systems. The fragmentation behaviour of deprotonated isoxazole and oxazole is analogous to that of the isothiazole and thiazole systems.
