Six new 4-amino-N-heteroaryl,N-[(2-phenyl-4H-1-benzopyran-4- oxo-6-yl)metil]benzensulfonamide derivatives, (3a-3f) were prepared by reacting 6-bromomethylflavone with the corresponding sulfonamide derivatives and their antimicrobial activities against Escherichia coli were evaluated. All of the compounds exhibited better activity (except compound 3c) than the corresponding sulfonamide derivatives.

A dinuclear cobalt complex bearing the ligand bis(3-(2-pyridylmethyleneamino)phenyl) sulfone (BPMAPS) was prepared. It is proposed that the structure of this is [Coz(BPMAPS)(m-0AcMhemi-Et)]PF6 wherein the cobalt centers are bridged by two carboxylato groups in m-fashion and a hemiacetal with an ethoxy group (hemi-Et). This proposal is based on the similarity of the FT-IR, UV-Vis, and FAB-MS results with the crystallographically characterized dinuclear manganese complex [Mn2(BPMAPS)(m-OAcMhemi-Me)]PF6, and elemental analysis results.

Synthesis And Analgesic And Anti-Inflammatory Activity Of New Pyridazinones, Deni̇z S. Doğruer, M. Fethi̇ Şahi̇n, Esra Küpeli̇, Erdem Yeşi̇lada
Turkish Journal of Chemistry
A new series of 2-(6-oxo-3,5-diphenyl-6H-pyridazin-1-yl)- acetamides and 3-[6-oxo-3,5-diphenyl-6H-pyridazin-1-yl)-propanamides were synthesized and evaluated in terms of their analgesic and anti-inflammatory activities. All compounds except for 7g were more potent than aspirin in a p-benzoquinone--induced writhing test at 100 mg/kg dose. Compounds 7b, 7c and 7e had the highest anti-inflammatory activity; compound 7e was the most potent in terms of analgesic and anti-inflammatory activities and had no ulcerogenic side effects.
Synthesis, Characterization And Primary Antituberculosis Activity Evaluation Of 4-(3-Coumarinyl)-3-Benzyl-4-Thiazolin-2-One Benzylidenehydrazones, Aysel Gürsoy, Ni̇lgün Karali̇
Synthesis, Characterization And Primary Antituberculosis Activity Evaluation Of 4-(3-Coumarinyl)-3-Benzyl-4-Thiazolin-2-One Benzylidenehydrazones, Aysel Gürsoy, Ni̇lgün Karali̇
Turkish Journal of Chemistry
In this study a new series of 4-(3-coumarinyl)-3-benzyl-4-thiazolin- 2-one benzylidenehydrazones 3a-t was synthesized. Structures of the title compounds were elucidated by elemental analyses and spectrometric data (IR, ^1H-NMR, ^{13}C-NMR and EIMS). 3a-t were evaluated for antituberculosis activity against Mycobacterium tuberculosis} H37Rv in BACTEC 12B medium using the BACTEC 460 radiometric system.
Synthesis Of Montiporynes A And B, Traci Jenelle Speed
Synthesis Of Montiporynes A And B, Traci Jenelle Speed
Honors Theses
This thesis reports the first complete synthesis of monriporynes A and B. isomeric diacetylenes that bear α, β unsaturated ketone functionalities. Recently isolated from the stony coral Montipora sp. these compounds are reported to possess in vitro cytotoxic activity against several human solid tumor cells. We have synthesized both isomers in three simple steps. In the first step, l-iodononyne was prepared by reacting 1-nonyne with N-iodosuccinimide and a catalytic amount of silver nitrate. This iodoalkyne was then coupled with propargyl alcohol using copper iodide as the catalyst to give 2,4dodecadiynyl alcohol. Finally, the diacetylenic alcohol was subjected to the Swern …
