Efficient reduction of nitro compounds into amines is an important industrial transformation. So, it is a great deal to design new catalysts for efficient reduction of the nitro compounds especially in water. In this work, a new magnetic Pd/activated carbon nanocomposite (CoFe2O4@Pd/AC) was synthesized via metal-impregnation-pyrolysis method. The CoFe2O4@Pd/AC was fully characterized by FT-IR, PXRD, FESEM, TEM, VSM, EDX-mapping and BET techniques. The results showed that CoFe2O4@Pd/AC is a highly reactive and easily recoverable magnetic catalyst for the reduction of the nitro compounds by using NaBH4 in water. For instance, aniline was obtained in high yield (99%) after 75 ?min at 25 ?C by using just 6 ?mg of the catalyst. In addition, CoFe2O4@Pd/AC was recovered by a simple magnetic decantation and it exhibits stable activity and remains intact during the catalytic process with no significant loss in activity (8 cycles).

A new series of thiadiazole linked pyrazole benzenesulfonamide derivatives were synthesized by the condensation of aldehydic pyrazole with aryl substituted thiadiazole amine followed by Schiff base reaction. The synthesized compounds (6a-o) were characterized by IR, NMR, and Mass spectral data, further evaluated their in-vivo anti-inflammatory, analgesic and invitro COX-II inhibition assay. The compounds 6b and 6m showed most significant in-vivo antiinflammatory with 72.33 &71.17% inhibition along analgesic activity having 67.89% and 71.37 % respectively. Their selectivity against COX-II enzyme with selectivity index 67.81 and 66.38 was established for 6b and 6m, which is compared with Celecoxib. During the gastric ulceration study, selected compounds couldn't observed any ulcerogenic effect on gastric mucosa. The in-silico pharmacokinetic profile and molecular docking study exposed very good binding affinity towards the Cyclooxygenase (COX-II) enzyme (PDB Id: 3PGH), therefore the compounds 6b and 6m are used as promising lead candidates for the support of drug development.

, p. 311 - 314 (2019/01/21)
Derivatives of thiadiazolo [2',3':2,3] imidazo [4,5-b] quinoxalines were synthesized by the reaction of 5-substituted-1,3,4-thiadiazol-2-amine with 2,3-dichloro-6,7- dinitroquinoxalines. The synthesized compounds were characterized by using spectral data. They were then screened for analgesic, anti-inflammatory and ulcerogenic activity.

The enzymatic inhibition of histone deacetylase activity has come out as a novel and effectual means for the treatment of cancer. Two novel series of 2-[5-(4-substitutedphenyl)-[1,3,4]-oxadiazol/thiadiazol-2-ylamino] -pyrimidine-5-carboxylic acid (tetrahydro-pyran-2-yloxy)-amides were designed and synthesized as novel hydroxamic acid based histone deacetylase inhibitors. The antiproliferative activities of the compounds were investigated in vitro using histone deacetylase inhibitory assay and MTT assay. The synthesized compounds were also tested for antitumor activity against Ehrlich ascites carcinoma cells in Swiss albino mice. The efforts were also made to establish structure-activity relationships among synthesized compounds. The results of the present studying indicates 2,5-disubstituted 1,3,4-oxadiazole/thiadiazole as promising surface recognition moiety for development of newer hydroxamic acid based histone deacetylase inhibitor.
