A STAGE-SPECIFIC BLOCK IS PRODUCED IN CARROT SOMATIC EMBRYOS BY 1,2-BENZISOXAZOLE-3-ACETIC ACID

1,2-Benz-isoxazol-3-acetic acid is slightly toxic to unorganized growing carrot cells and completely prevents somatic embryogenesis beyond the globular stage. Its action is time dependent: if added early, it affects the determination of the early stages; if added later, after determination has occurred, it has practically no effect. The blocked forms can evolve, in the presence of the compound, creating secondary embryos that, in turn, are arrested at the globular stage. Since the secondary embryos adhere to the primary ones, irregular polyembryonic masses of typical appearance are created. The internal structures of the blocked globular embryos were examined and were shown to be enlarged, vacuolized and detached from the central cells. The protoderm also displayed an altered appearance. These data, when considered together with the effects of the compound on rooting and callus formation, suggest that benz-isoxazol acetic acid acts as a weak auxin.

When developing chemical systems it’s of course important to gain a deep understanding of the chemical reaction process. 57-11-4, Name is Stearic acid, SMILES is CCCCCCCCCCCCCCCCCC(O)=O, in an article , author is Hoy, Sheridan M., once mentioned of 57-11-4, Application In Synthesis of Stearic acid.

Oral zonisamide (Zonegran(A (R))) is a benzisoxazole derivative chemically unrelated to other antiepileptic drugs (AEDs). It is approved in the EU as an adjunct to other AEDs in the treatment of pediatric patients aged a parts per thousand yen6 years with partial seizures, with or without secondary generalization. In a randomized, double-blind, multinational, phase III study in pediatric patients aged 6-17 years with partial seizures, the proportion of patients achieving a a parts per thousand yen50 % reduction from baseline in seizure frequency per 28 days during the maintenance treatment period was significantly higher with adjunctive therapy with zonisamide than placebo. The antiepileptic efficacy of zonisamide was sustained during a 59-week extension study in this patient population. Zonisamide was generally well tolerated in these studies, with the majority of adverse events being mild or moderate in severity. Thus, oral zonisamide as an adjunctive therapy to other AEDs provides a useful option in the treatment of pediatric patients aged a parts per thousand yen6 years with partial seizures.

The antiepileptic drug zonisamide was considered to act as a weak inhibitor of the zinc enzyme carbonic anhydrase (CA, EC 4.2. 1.1) (with a K, of 4.3 mu M against the cytosolic isozyme 11). Here we prove that this is not true. Indeed, testing zonisamide in the classical assay conditions of the CO2 hydrase activity of hCA II, with incubation times of enzyme and inhibitor solution of 15 min, a K-1 of 10.3 mu M has been obtained. However, when the incubation between enzyme and inhibitor was prolonged to 1d h, the obtained K-1 was of 35.2 nM, of the same order of magnitude as that of the clinically used sulfonamides/sulfamates acetazolantide, methazolamide, ethoxzolamide and topiramate (K(1)s in the range of 5.4-15.4 nM). The inhibition of the human mitochondrial isozyme hCA V with these compounds has been also tested by means of a dansylamide competition binding assay, which showed zonisamide and topiramate to be effective inhibitors, with K(1)s in the range of 20.6-25.4 nM. The X-ray crystal structure of the adduct of hCA 11 with zonisamide has also been solved at a resolution of 1.70 A, showing that the sulfonamide moiety participates in the classical interactions with the Zn(II) ion and the residues Thr199 and Glu106, whereas the benzisoxazole ring, is oriented toward the hydrophobic half of the active site, establishing a large number of strong van der Waals interactions (< 4.5 A) with residues Gln92, Vall2l, Phe131, Leu198, Thr200, Pro202.

A simple colorimetric and fluorimetric chemosensor 3,5-dinitro-(N-phenyl)benzamide (DNBA), was synthesized for selective determination of cyanide anion in organic and aqueous solutions via novel chemodosimeter approach. The chemosensorDNBAshowed a chromogenic and fluorogenic selective response to CN(-)against competing anions such as F-, AcO-, and H(2)PO(4)(-)in organic (DMSO and ACN) and in aqueous solutions (in DMSO/H2O: 8:2, v/v). The intensive colorimetric and fluorimetric color changes were observed in ambient light and UV-light (lambda(ex). 365 nm) after cyanide interacted withDNBA. A method that can be used in the synthesis of new biologically active benzisoxazole compound was described by the reaction ofDNBAwith TBACN and KCN in DMSO or DMSO/H2O, respectively. All interaction mechanisms betweenDNBAand cyanide and fluoride anions were demonstrated by experimental studies using various spectroscopic methods such as UV/Vis, fluorescence,H-1/C-13 NMR, and mass spectrometry as well as X-ray diffraction method. In addition, the experimental results were also explained with theoretical data. The spectroscopic results showed that cyanide interacts with three different mechanisms; deprotonation, nucleophilic aromatic substitution, and formation of benzisoxazole ring.

Zonisamide is an antiepileptic drug used as adjunctive therapy for refractory partial seizures in adults. Because of the multiple mechanisms of action, it shows a broad spectrum of anticonvulsant activity and has been effective in several types of seizures, including partial and generalized seizures, tonic-clonic seizures and absence seizures in patients unresponsive to other anticonvulsants. Myoclonic epilepsy, Lennox-Gastaut syndrome and infantile spasms have also been treated effectively with zonisamide. Recent clinical studies have demonstrated additional potential for therapeutic use in neuropathic pain, bipolar disorder, migraine, obesity, eating disorders and Parkinson’s disease. Despite adverse events, zonisamide is relatively safe and well tolerated in patients, and shows low discontinuation rate. It has a good pharmacokinetic profile and a low drug interaction potential. Zonisamide is considered as a drug that effectively reduces the frequency of partial seizures. (C) 2005 Prous Science. All rights reserved.

Herein, we have designed various benzisoxazole acetamide derivatives with and without glycine spacer as DPP-IV inhibitors. Compounds 9a-d and 11a-e were synthesized and screened for their in vitro DPP-IV inhibition. Compounds 11a and 11c showed moderate activity for DPP-IV inhibition, whereas other remained inactive at 25-200 mu M concentrations. DPP-IV inhibition can be a good strategy for modulating diabetes and cancer; hence, we have screened compounds 9a-d and 11a-e for their anticancer activity using MTT assay against A549 and MCF7 cell lines. Compounds 9a-d without glycine spacer have shown good anticancer activity compared to compounds 11a-e with glycine spacer. Compound 9b has shown moderate activity with IC50 values 4.72 +/- 0.72 and 4.39 +/- 0.809 mu M against A549 and MCF7 cell lines, respectively. Interestingly, compound 9c with cyano group has shown very good anticancer activity with IC50 2.36 +/- 0.34 mu M against MCF7 cell line as compared to fluorouracil with IC50 45.04 +/- 1.02 mu M.
