Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Sulfonamides are considered to be pharmaceutically important class of compounds. In the present work, N-(2,4-dimethylphenyl)-4-toluenesulfonamide was synthesized by the reaction of 2,4-dimethylaniline and 4-tosyl chloride (4-methylbenzenesulfonyl chloride) using 10% aqueous Na2CO3 solution as reaction medium. At the second step, the synthesized molecule was made to react with different alkyl/aralkyl halides to yield the target compounds,using N,N-dimethylformamide (DMF) as reaction medium and lithium hydride as an activator. The synthesis of all the compounds was verified by spectral techniques using IR, 1H-NMR and EIMS; and further examined for their anti-enzymatic activities. The synthesized compounds represented the most potential against -glucosidase and lipoxygenase enzymes. 80 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In the present work, Different substituted derivatives of 5-substituted-1,3,4-oxadiazole-2-thiols were synthesized by successive conversions of 5-substituted carboxylic acids into respective ester, hydrazide and 1,3,4-oxadiazole. Finally the target compounds were obtained by reaction of 5-substituted-1,3,4-oxadiazole-2-thiols with a series of various electrophiles,in N,N-dimethyl formamide (DMF) in the presence of sodium hydride (NaH)which acts as a base. The structural characterization of these newly synthesized compounds was done by IR, 1H-NMR and EI-MS spectral data. All these compounds were evaluated for their enzyme inhibitory potentials and found to exhibit broad range spectrum against acetylcholinesterase, butyrylcholinestrase and lipoxygenase enzymes and hence are suitable entrants for the treatment of Alzheimer's disease. 84 pp. Englisch. …

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The presented study encompasses the synthesis of a series of sulfonamides derivatives of 1-amino-2-phenylethane in excellent yield by reaction with various aryl sulfonyl chlorides, in the presence of aqueous sodium carbonate solution under dynamic pH control. These projected structures of the synthesized derivatives were characterized by IR, 1H-NMR and EIMS spectral techniques. Moreover, the screening of derivatives against acetyl cholinesterase (AChE), butyryl cholinesterase (BChE) and lipoxygenase (LOX) enzymes rendered these molecules as potent inhibitors of cholinesterase enzymes, relative to Baicalein and Eserine, which were used as reference standard. 60 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -A series of potential biologically active 4,5-dimethoxy-2-[3-oxo-3-phenylprop-1-en-1-yl]benzenesulfonamides was synthesized. 3,4-Dimethoxybenzaldehyde was condensed with acetophenone followed by its chlorosulfonation to get 4,5-dimethoxy-2-[3-oxo-3-phenylprop-1-en-1-yl]benzenesulfonyl chloride, which was further reacted with a number of amines and hydrazides to get the 4,5-dimethoxy-2-[3-oxo-3-phenylprop-1-en-1-yl]benzenesulfonic acid derivatives. All the synthesized compounds were subjected to preliminary evaluation for their antibacterial activity against selected strains of gram positive and gram negative bacteria. Some of the assayed compounds showed marked activity. 64 pp. Englisch.…

Taschenbuch. Condición: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - The family Symplocaceae was first recognized by D. Don (Symplocineae, Prodr. Fl. Nepal. 144.1825, excluding Schopfia) but most authors including De Candolle (Prodr. 8: 244.1844), Bentham and Hooker (Gen. Pl. 2: 668.1876), Stewart and Brandis (For. Fl.299.1874) and C. B. Clarke in Hook. f. (Fl. Brit. Ind. 3: 572.1882) included it in family Styracaceae. However, Miquel in Martius (Fl. Brass. 7: 22. 1842), Engler and Prantl (Pflanzenfam 4 (1): 168. 1890) following D. Don, treated it as a separate family. Lawrence (Taxon. Vasc. Pl. 665. 1951) and C. G. G. Van Steenis (Fl. Males. 4: 49. 1954) advocate its separate identity from Styracaceae on the basis of its inferior or semi-inferior, completely 2-5 loculed ovary, drupe crowned by persistent calyx lobes, 1-4 seriate or fasciculate (adelphous) stamens with avoid-subglobose anthers and absence of stellate hairs or scales. Hutchison (Gen. Fl. Pl 2: 39.1968; Fam. Fl. Pl. 1: 171.1960) also treats it as a separate unigeneric family. …
