We tested the morphogenetic and cell elongating activity of 1,2-benzisoxazole-3-one, a compound similar to 1,2-benzisoxazole-3-acetic acid but lacking the lateral carbon chain. For comparison, we tested also the activity of indole-2,3-dione, having the same indolic ring as indole-3-acetic acid but no lateral carbon chain. The tests were made on the regeneration of tomato (Lycopersicon esculentum Miller var. Alice) from cotyledons and on pea (Pisum sativum L. var. Alaska) stem elongation. We found that 1,2-benzisoxazole-3-one retains part of the high shoot inducing activity of 1,2-benzisoxazole-3-acetic acid, while indole-2,3-dione is inactive. Both compounds have no effect on root induction or cell elongation. It seems therefore that the activity of 1,2-benzisoxazole-3-acetic acid is partly related to the structure of its ring, and that also in this respect 1,2-benzisoxazole-3-acetic acid differs from other auxin-like compounds.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 40052-13-9, you can contact me at any time and look forward to more communication. Application In Synthesis of 3-Tert-butoxy-3-oxopropanoic acid.

The bioreduction of N-oxide compounds is the basis for the mode of action of a number of biologically active molecules. These compounds are thought to act by forming a reactive oxygen species through an intracellular reduction and subsequent redox cycling process within the organism. With these results in mind, the preliminary investigation into the electrochemical reduction of the benzisoxazole 2-oxide ring system was undertaken, with the thought that this class of compounds would reduce in a similar fashion to other N-oxide heterocycles. The electrochemical reduction of 3-phenyl-1,2-benzisoxazole 2-oxide on boron-doped diamond was studied using cyclic and square wave voltammetry as well as controlled potential electrolysis and HPLC for qualitative identification of the reaction products. It was found that the reduction proceeded with an initial quasi-reversible one-electron reduction followed by the very fast cleavage of either the endocyclic or exocyclic N-O bond. Subsequent electron transfer and protonation resulted in an overall two-electron reduction and formation of the 2-hydroxyaryl oxime and benzisoxazole. These results are analogous to those observed in the electrochemical reduction of other heterocyclic N-oxides albeit the reduction of the benzisoxazole N-oxides takes place at a more negative potential. However, these encouraging results warrant further investigation into the reduction potential of substituted benzisoxazole N-oxides as well as to elucidate and characterize the nature of the intermediate species involved.

In an article, author is Minato, H, once mentioned the application of 123-99-9, Name is Water-soluble azelaic acid, molecular formula is C9H16O4, molecular weight is 188.2209, MDL number is MFCD00004432, category is benzisoxazole. Now introduce a scientific discovery about this category, Related Products of 123-99-9.

Purpose: The antiepileptic effects of zonisamide (ZNS) have been well documented experimentally and clinically. The purpose of this study was to examine whether ZNS reduces cerebral damage after transient focal ischemia in rats. Methods: Ischemia was induced by a transient occlusion of the left middle cerebral artery (MCA) with a 3-0 nylon monofilament for 90 min. Neurological evaluation was performed by measuring the event of neurological deficit of the contralateral forepaw and hindpaw at 10 min and 1 day after MCA occlusion (MCAo). Brain infarct size was determined by measuring triphenyltetrazonium chloride-negative stained area of the serial brain sections 1 day after MCAo. Results: The pre-or postischemic treatment with ZNS [(10-100 mg/kg p.o.), 30 min before and 4 h after or 15 min and 4 h after the occlusion] markedly reduced cerebral damage in the ipsilateral hemisphere and the neurological deficit induced by transient ischemia. The reducing effect on the damage was observed in the cortical and subcortical regions. Preischemic treatment with carbamazepine (CBZ 60 mg/kg p.o. twice 30 min before and 4 h after MCAo) tended to reduce the cerebral damage and neurological deficit, but the lower dose (20 mg/kg p.o. twice) did not. Valproate (VPA 1,000 mg/kg p.o. twice) also had no effect. Conclusions: ZNS at the anticonvulsant dose, unlike CBZ and VPA, ameliorated the brain infarction and the event of neurological deficit after transient focal cerebral ischemia. These data suggest that ZNS has therapeutic potential in protecting against ischemic cerebral damage, such as stroke.

Neuroleptic malignant syndrome is thought to be a result of dopamine D-2 receptor blockade in the striatum of the basal ganglia. Risperidone, a benzisoxazole derivative antipsychotic, has high serotonin 5-HT2 receptor blockade and dose-related D-2 receptor blockade. The high ratio is believed to impart the low frequency of extrapyramidal symptoms with risperidone at low dosages. With this low frequency of extrapyramidal symptoms, it was thought the frequency of neuroleptic malignant syndrome might also be lowered. A 73-year-old woman developed neuroleptic malignant syndrome after monotherapy with risperidone. The syndrome reversed after discontinuing risperidone and starting treatment with dantrolene and bromocriptine. It appears that the protection from extrapyramidal side effects observed with risperidone does not ensure protection from neuroleptic malignant syndrome.
