Chemistry, like all the natural sciences, begins with the direct observation of nature— in this case, of matter. 3721-95-7, Name is Cyclobutanecarboxylic acid, SMILES is O=C(C1CCC1)O, in an article , author is Giorgi, G, once mentioned of 3721-95-7, Quality Control of Cyclobutanecarboxylic acid.

Different mass spectrometric methods, stable isotope labeling, and theoretical calculations have allowed us to structurally characterize and differentiate the isomeric ion structures produced by the two heteroaromatic isomers 3-methyl-1,2-benzisoxazole and 2-methyl-1,3-benzoxazole. The low-energy collision induced dissociation spectra of their molecular ions show large differences. Although both of them produce abundant loss of CO, that involves a carbon atom of the benzene ring, the 2-methyl-1,3-benzoxazole also shows abundant [M-CHO](+) ions at m/z 104, the intensity of which is quite low in the case of its isomer 3-methyl-1,2-benziscxazole. In addition, MS/MS measurements of fragment ions show characteristic differences that allow distinction among the isomers depending on the original arrangement of the atoms in the five-membered ring. Theoretical ab initio calculations have allowed to determine chemico-physical properties of different ions and to propose a rationalization of the decomposition pathways followed by the two benz(is)oxazole isomers.

A new thermal process to prepare spiroindolin-3-ones from 3-substituted 2,1-benzisoxazoles in good yields (70-85%) is described. The highest yields were observed when microwave irradiation was used. The method does not require the use of any additive or catalyst. A possible reaction mechanism involving a nitrene key intermediate is proposed.

Although the majority of people with epilepsy have a good prognosis and their seizures can be well controlled with pharmacotherapy, up to one-third of patients can develop drug-resistant epilepsy, especially those patients with partial seizures. This unmet need has driven considerable efforts over the last few decades aimed at developing and testing newer antiepileptic agents to improve seizure control. One of the most promising antiepileptic drugs of the new generation is zonisamide, a benzisoxazole derivative chemically unrelated to other anticonvulsant agents. In this article, the authors present the results of a systematic literature review summarizing the current evidence on the efficacy and tolerability of zonisamide for the treatment of partial seizures. Of particular interest within this updated review are the recent data on the use of zonisamide as monotherapy, as they might open new therapeutic avenues.

Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. 600-18-0, Name is 2-Oxobutanoic acid, SMILES is CCC(=O)C(O)=O, belongs to benzisoxazole compound. In a article, author is Kociolek, Martin G., introduce new discover of the category.

A series of 2-hydroxyaryl ketoximes were converted to the corresponding 1,2-benzisoxazole 2-oxides by treatment with iodobenzene diacetate (in acetic acid or methanol) or N-chlorosuccinimide in water. Both methods gave moderate to excellent yields for a variety of substituted oximes under mild conditions within short reaction times. The latter method has the advantages of an aqueous solvent and lack of halogenated organic by-products.

1 Zonisamide, an anticonvulsant developed in Japan, is structurally similar to serotonin. Zonisamide has been proven to have a pharmacological profile that is very similar to that of carbamazepine. Thus, the effect of zonisamide was examined in 24 psychiatric patients: 15 with bipolar manic state, 6 with schizoaffective manic state, and 3 schizophrenic excitement. 2 Approximately 25% of all the patients and 33% of the bipolar manic patients showed remarkable global improvement with the addition of zonisamide. Approximately 71% of all the patients and 80% of the bipolar group had more than moderate global improvement. 3 No serious adverse reactions were found and no patients required zonisamide withdrawal. One patient developed both leukocytosis and mildly abnormal liver function test. One developed leukocytosis and another reported mild sleepiness. These reactions disappeared when zonisamide was discontinued.

Category: Benzisoxazole, The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction. 1191-25-9, Name is 6-Hydroxyhexanoic acid, molecular formula is C6H12O3. In an article, author is Yoshimi, K,once mentioned of 1191-25-9.

Although possible usefulness of non-selective monoamine oxidase (MAO) inhibitors for Parkinson’s disease therapy has been suggested in the literature, MAO inhibitors whose inhibition is reversible and have dual action to both MAO-A and -B subtypes is not available yet. Subtype selectivity and reversibility of a series of novel MAO inhibitors, 3-(2-aminoethoxy)-1,2-benzisoxazole derivatives, were studied. Several dual MAO inhibitors, which inhibit both MAO-A and -B, were obtained. When administered to mice, their effects were generally reversible. Among the derivatives, RS-1636 and RS-1653 had much longer duration of brain MAO-B inhibition than that of MAO-A. In vitro, the inhibited MAO-A activity by these compounds was partially recovered by buffer change at 4degreesC, while little MAO-B activity was recovered. Although it is not fully elucidated yet, the reversibility of these inhibitors is probably determined primarily by this dissociation profile. This unique differential reversibility indicates that optimization of the balance of actions can be achieved by differentiating reversibility to each target molecule.
