1-Amino-2-phenylethane derived sulfonamides
ISBN: 9783659606359 / Angielski / Miękka / 2014 / 60 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. 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,...

5-Substituted-1,3,4-Oxadiazole-2-Thiols
ISBN: 9783659595288 / Angielski / Miękka / 2014 / 84 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. 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...

Potential Candidates for Drug Designing
ISBN: 9783639247510 / Angielski / Miękka / 2011 / 120 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. 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)...

Arachis Hypogea
ISBN: 9783843392150 / Angielski / Miękka / 2012 / 76 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Arachis hypogaea (peanut or groundnut) is an economically important crop. Thousands of peanut cultivars are grown in the world and many studies have been carried out on them but, to the best of our knowledge, no salient work has been done on Pakistani cultivar so far. Here, we report the chemical composition of Pakistani cultivar of Arachis hypogaea (peanut or groundnut) and its antiradical activities by 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging and Phosphomolybdenim Complex (PC) method. This study revealed that Pakistani cultivar exhibited an almost equal antioxidant potential...

Sulfonated Derivatives of 2,4-Xylidine: Possible Therapeutic Agents
ISBN: 9783659636585 / Angielski / Miękka / 2014 / 80 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. 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...
