New N-aryl isoxazolecarboxamides and N-isoxazolylbenzamides as anticonvulsant agents

We prepared a series of N-aryl isoxazolecarboxamide, N-isoxazolylbenzamide compounds and derivatives and studied their anticonvulsant action in MES and MMS tests. Some of these reveal considerable activity, especially with respect to MES test. The disubstitution in the 2.6-position on the phenyl ring by two methyl groups would appear to be of primary importance for the activity. The amide bridge between the phenyl and isoxazolic rings, whether of the anilide or benzamide type, seems to show similar anticonvulsant behavior. We have selected the derivatives 8 (N-(2.6-dimethylphenyl)-5-methyl-3-isoxazolecarboxamide, 12 (N-(2.6-dimethylphenyl)-5-hydroxymethyl-3-isoxazolecarboxamide) and 51 (N-(5-methyl-3-isoxazolyl)-2.6-dimethylbenzamide) which are presently being studied in more extended pharmacological tests.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. COA of Formula: C10H15NO3, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 91252-54-9, in my other articles.

Structure-affinity relationships of 5?-aromatic ethers and 5?-aromatic sulfides as partial A1 adenosine agonists, potential supraventricular anti-arrhythmic agents

Atrial fibrillation (AF) is the most commonly encountered sustained clinical arrhythmia with an estimated 2.3 million cases in the US (2001). A 1 adenosine receptor agonists can slow the electrical impulse propagation through the atrioventricular (AV) node (i.e., negative dromotropic effect) resulting in prolongation of the stimulus-to-His bundle (S-H) interval to potentially reduce ventricular rate. Compounds that are full agonists of the A1 adenosine receptor can cause high grade AV block. Therefore, it is envisioned that a compound that is a partial agonist of the A1 adenosine receptor could avoid this deleterious effect. 5? Phenyl sulfides (e.g., 17, EC50=1.26muM) and phenyl ethers (e.g., 28, EC50=0.2muM) are partial agonists with respect to their AV nodal effects in guinea pig isolated hearts. Additional affinity, GTPgammaS binding data suggesting partial activity of the A1 adenosine receptor, and PK results for 5? modified adenosine derivatives are shown.

Novel inhibitors of Staphylococcus aureus RnpA that synergize with mupirocin

We recently discovered RnpA as a promising new drug discovery target for methicillin-resistant S. aureus (MRSA). RnpA is an essential protein that is thought to perform two required cellular processes. As part of the RNA degrasome Rnpa mediates RNA degradation. In combination with rnpB it forms RNase P haloenzymes which are required for tRNA maturation. A high throughput screen identified RNPA2000 as an inhibitor of both RnpA-associated activities that displayed antibacterial activity against clinically relevant strains of S. aureus, including MRSA. Structure-activity studies aimed at improving potency and replacing the potentially metabotoxic furan moiety led to the identification of a number of more potent analogs. Many of these new analogs possessed overt cellular toxicity that precluded their use as antibiotics but two derivatives, including compound 5o, displayed an impressive synergy with mupirocin, an antibiotic used for decolonizing MSRA whose effectiveness has recently been jeopardized by bacterial resistance. Based on our results, compounds like 5o may ultimately find use in resensitizing mupirocin-resistant bacteria to mupirocin.

Oxidation of alkylarenes by nitrate catalyzed by polyoxophosphomolybdates: Synthetic applications and mechanistic insights

Alkylarenes were catalytically and selectively oxidized to the corresponding benzylic acetates and carbonyl products by nitrate salts in acetic acid in the presence of Keggin type molybdenum-based heteropolyacids, H3+xPVxMo12-xO40 (x = 0-2). H 5PV2Mo10O40 was especially effective. For methylarenes there was no over-oxidation to the carboxylic acid contrary to what was observed for nitric acid as oxidant. The conversion to the aldehyde/ketone could be increased by the addition of water to the reaction mixture. As evidenced by IR and 15N NMR spectroscopy, initially the nitrate salt reacted with H5PV2Mo10O 40 to yield a NVO2+[H 4PV2Mo10O40] intermediate. In an electron-transfer reaction, the proposed NVO2 +[H4PV2Mo10O40] complex reacts with the alkylarene substrate to yield a radical-cation-based donor-acceptor intermediate, NIVO2[H4PV 2Mo10O40]-ArCH2R+.. Concurrent proton transfer yields an alkylarene radical, ArCHR., and NO2. Alternatively, it is possible that the NVO 2+[H4PV2Mo10O 40] complex abstracts a hydrogen atom from alkylarene substrate to directly yield ArCHR. and NO2. The electron transfer-proton transfer and hydrogen abstraction scenarios are supported by the correlation of the reaction rate with the ionization potential and the bond dissociation energy at the benzylic positions of the alkylarene, respectively, the high kinetic isotope effect determined for substrates deuterated at the benzylic position, and the reaction order in the catalyst. Product selectivity in the oxidation of phenylcyclopropane tends to support the electron transfer-proton transfer pathway. The ArCHR. and NO2 radical species undergo heterocoupling to yield a benzylic nitrite, which undergoes hydrolysis or acetolysis and subsequent reactions to yield benzylic acetates and corresponding aldehydes or ketones as final products.
