Modeling chemical reactions helps engineers virtually understand the chemistry, optimal size and design of the system, and how it interacts with other physics that may come into play. 133-37-9, Name is (2R,3R)-rel-2,3-Dihydroxysuccinic acid, SMILES is O=C(O)[C@H](O)[C@@H](O)C(O)=O, in an article , author is Cox, Joanna H., once mentioned of 133-37-9, Application In Synthesis of (2R,3R)-rel-2,3-Dihydroxysuccinic acid.

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.

The system of GABA transporters in neural cells constitutes an efficient mechanism for terminating inhibitory GABAergic neurotransmission. This transport system is an important therapeutical target in epileptic disorders, but potentially also in other neurological disorders. Thus, selective intervention in GABA uptake has been the subject of extensive research for several decades. In a series of lipophilic diaromatic derivatives of (RS)3-hydroxy-4-amino-4,5,6,7-tetrahydro-1,2-benzisoxazole (exo-THPO), N-[4,4-bis(3-methyl-2-thienyl)-3-butenyl]-3-hydroxy-4-(methylamino)4,5,6,7-tetrahydrobenzo[d]isoxazol-3-ol (EF1502) turned out to be an equipotent inhibitor at the mouse transporters GAT1 and GAT2 (BGT-1) but inactive at GAT3 and GAT4. This novel pharmacological profile among GABA uptake inhibitors prompted a thorough investigation of the in vivo properties of this compound. These investigations have for the first time demonstrated a functional role for GABA transporter subtype GAT2/ BGT-1, which points to the therapeutic relevance of inhibiting this transporter subtype. An overview of the development and characterisation of EF1502 is presented here. (C) 2006 Elsevier Ltd. All rights reserved.

Different 7-amino-3-methyl-5-(3′-aryl prop-2′-enoyl)-1,2-benzisoxazoles were synthesized by the interaction of appropriate 5-acetyl-7-amino-3-methyl-1,2-benzisoxazole with different aromatic aldehydes using piperidine. Tetra-O-acetyl-alpha-D-glucopyranosyl bromide was prepared by the reaction of powdered glucose pentaacetate and bromine in the presence of chloroform. Condensation of tetra-O-acetyl-alpha-D-glucopyranosyl bromide with 7-amino-3-methyl-5-(3′-aryl prop-2′-enoyl)-1,2-benzisoxazoles furnished 7-amino-(2,3,4,6-tetra-O-acetyl-beta-D-glucopyranosyl)-3-methyl-5-(3′-aryl prop-2′-enoyl)-1,2-benzisoxazoles which on deprotection gave 7-amino-(beta-D-glucopyranosyl)-3-methyl-5-(3′-aryl prop-2′-enoyl)-1,2-benzisoxazoles. Polarographic studies revealed the presence of reducible groups with distinguished E-1/2 values. All compounds were screened for antimicrobial activities, and some compounds showed potent antibacterial and antifungal activities. [GRAPHICS]

The present study is to investigate the cytotoxicity properties and haematological indices of synthesized molecules (S1-S4) in comparison to the standard drug 5 fluorouracil which reflects the anticancer potentials of the above molecules. Cytotoxicity studies were performed by in vitro MTT (3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyl teterazolium bromide) assay. Haematological studies were done by drawing blood in the drug and synthesized molecules administered animals by retroorbital method. Haemoglobin, RBC, WBC, lymphocytes, Monocytes and Granulocytes counts were measured. All the above experiments were performed against Ehrlich ascites carcinoma (EAC) in Swiss albino mice. The percentage cytotoxicity and percentage viable cell counts revealed anticancer properties of the synthesized molecules. RBC count indicated protection of cell membrane from destruction and the WBC counts along with lymphocytes, Monocytes and granulocytes also show the immunoprotective characteristics of the novel molecules. Thus it has been concluded that the synthesized molecules (S1-S4) if supported by further molecular studies may have a promising role to play as anticancer agents.

The rate of decarboxylation of 6-nitrobenzisoxazole-3-carboxylate, NBOC, was determined in micelles of N-hexadecyl-N,N,N-trimethylammonium bromide or chloride ( CTAB or CTAC), N-hexadecyl-N,N-dimethyl-3-ammonium-1-propanesulfonate (HPS), N-dodecyl-N,N-dimethyl-3-ammonium-1-propanesulfonate (DPS), N-dodecyl-N, N,N-trimethylammonium bromide (DTAB), hexadecylphosphocholine (HPC), and their mixtures. Quantitative analysis of the effect on micelles on the velocity of NBOC decarboxylation allowed the estimation of the rate constants in the micellar pseudophase, k(m), for the pure surfactants and their mixtures. The extent of micellar catalysis for NBOC decarboxylation, expressed as the ratio k(m)/k(w), where k(w) is the rate constant in water, varied from 240 for HPS to 62 for HPC. With HPS or DPS, k(m) decreased linearly with CTAB(C) mole fraction, suggesting ideal mixing. With HPC, k(m) increased to a maximum at a CTAB(C) mole fraction of ca. 0.5 and then decreased at higher CTAB(C). Addition of CTAB(C) to HPC, where the negative charge of the surfactant is close to the hydrophobic core, produces tight ion pairs at the interface and, consequently, decreases interfacial water contents. Interfacial dehydration at the surface in equimolar HPC/CTAB(C) mixtures, and interfacial solubilization site of the substrate, can explain the observed catalytic synergy, since the rate of NBOC decarboxylation increases markedly with the decrease in hydrogen bonding to the carboxylate group.

Some examples of the diverse research done by chemistry experts include discovery of new medicines and vaccines, improving understanding of environmental issues, and development of new chemical products and materials. In a document, author is Hosseini, Seyyedamirhossein, introducing its new discovery. Recommanded Product: 99-14-9.

Cyclic voltammetry and controlled-potential (bulk) electrolysis have been used to explore the electrochemical reduction of o-nitrobenzaldehyde (o-NBA) and 8 other aldehydes and ketones at glassy carbon cathodes in dimethylformamide containing various tetraalkylammonium tetrafluoroborate salts along with a proton donor (4-chlorophenol). Cyclic voltammograms for reduction of o-NBA exhibit three cathodic peaks attributable in succession to (a) one-electron generation of the nitro radical-anion, (b) three-electron formation of the hydroxylamine, and (c) two-electron production of benzisoxazole (anthranil). These findings have been employed to develop efficient controlled-potential (bulk) electrosyntheses of the following compounds: benzisoxazole, methylbenzo[c]isoxazole, [1,3]dioxolo[4 ‘,5 ‘,4,5]benzo[1,2-c]isoxazole, naphtho[2,3-c]isoxazole, 6-chlorobenzo[c]isoxazole, 6-methoxybenzo[c]isoxazole, 3-methyl-benzo[c]isoxazole, 3-isopropylbenzo[c]isoxazole, and 3-phenylbenzo[c]isoxazole. In addition, we have examined the use of a variety of proton donors to optimize the production of the desired product, and we have been able to recover the proton donor at the conclusion of the electrosynthesis. In each case, the synthesized product was separated by means of normal phase chromatography and identified with the aid of NMR spectros-copy, gas chromatography (GC), and gas chromatography-mass spectrometry (GC-MS). Isolated yields of the desired products range from 63 to 92 %. Moreover, our electrosyntheses are catalyst-free, environmentally green, and rapid (similar to 30 min).
