All the synthesized products are evaluated for their antifungal activity against Aspergillus niger, Aspergillus flavus, Fusarium oxisporium and Trichoderma viride and antibacterial activity against Bacillus substilis, Eschericha coli. Klebsiella pneumoneae and Staphylococcus aureus respectively. The structures of all the synthesized compounds have been determined by their spectral and microanalytical data. <br/> <br/>Page(s): 633-636 http://nopr.niscair.res.in/handle/123456789/1445 Title: An efficient synthesis of some 5-substituted-3-methyl-2-cyclohexen-1-ones using microwaves <br/> <br/>Authors: Jyothi, Divya; Prasad, S Hari <br/> <br/>Abstract: 3-Methyl-2-cyclohexenone and its 5-substituted-derivatives are prepared in high yields and short duration of time, using the microwave irradiation technique by the condensation of ethyl acetoacetate with eight different aldehydes and piperazine. <br/> <br/>Page(s): 630-632 http://nopr.niscair.res.in/handle/123456789/1444 Title: Synthesis and pharmacological screening of some 1,4-dihydropyridine and their derivatives for anticonvulsant activity <br/> <br/>Authors: Pattan, Shashikant R; Purohit, S S; Rasal, V P; Mallya, S; Marihal, S C; Khade, A B; Paschapur, M S <br/> <br/>Abstract: A new series of 1,4-dihydropyridine and their derivatives have been synthesized and the structures of the compounds have been confirmed by IR and NMR. The title compounds are evaluated for anticonvulsant activity by maximal electroshock method. Some of these compounds have been found to exhibit excellent anticonvulsant activity. <br/> <br/>Page(s): 626-629 http://nopr.niscair.res.in/handle/123456789/1443 Title: p-TsOH catalyzed efficient synthesis of bis(indolyl)methanes <br/> <br/>Authors: Raju, B China; Rao, J Madhusudana <br/> <br/>Abstract: p-TsOH is found to catalyze the electrophilic substitution reaction of indole with various carbonyl compounds under mild and convenient conditions to afford the corresponding bis(indolyl)methanes 1-7 in very good yields. <br/> <br/>Page(s): 623-625
