The influence of the moment of inertia on the rotational fluorescence depolarization is discussed. Based on experimental results obtained for five luminescent compounds: 2,5-diphenyloxazole (PPO), 2,2'-p-phenylene-bis(5-phenyloxazole) (POPOP) , p-bis[2-(5-a-naphthyloxazolyl)]-benzene (a-NOPON), 4-dimethylamino-a)-methylsulphonyl-trans-styrene (3 a) in n-parafines at low viscosity (from 0.22 x 1...

PURPOSE A group of 3,4-diaryl- 2(5H)furanones were synthesized to determine whether a N-acetylsulfonamido (SO2NHCOCH3) moiety could be used as a bioisosteric replacement for the traditional sulfonamide (SO2NH2) and methanesulfonyl (SO2CH3) COX-2 pharmacophores. METHODS In vitro COX-1 and COX-2 isozyme inhibition studies were carried out to acquire structure activity relationship data with res...

The first detailed study on free-radical polymerization, copolymerization and controlled radical polymerization of the cyclic push-pull-type monomer methylenelactide in comparison to the non-cyclic monomer α-acetoxyacrylate is described. The experimental results revealed that methylenelactide undergoes a self-initiated polymerization. The copolymerization parameters of methylenelactide and styr...

This data article contains two figures and one table supporting the research article entitled: "Continuous harvest of stem cells via partial detachment from thermoresponsive nanobrush surface" [1]. The table shows coating conditions of three copolymers, poly(styrene-co-acrylic acid) grafted with oligovitronectin, poly(styrene-co-N-isopropylacrylamide) and poly(styrene-co-polyethylene glycol met...

Some novel 3-phenyl-2-[(E)-2-phenylethenyl]-3,4-dihydroquinazolin-4-one derivatives possessing para-sulfonamides groups on the phenyl ring of the 2-phenylethenyl moiety have been synthesized and their COX-2 inhibitory activity evaluated. The stuctures of the synthesized compounds were confirmed  on the basis of  FT-IR, 1H-NMR, 13C-NMR and mass spectral data. The COX-2 inhibition screening assay...

hypoglycemic agent along with metformin. Although the management of diabetes was attempted by the “experts” of the Pharaoah of Egypt 3500 years ago and by Shushruta, the modern times efforts began only in the in the early 1900. In the year 1937, hypoglycemic activity of sulfur compounds was noted, and five years later, Michel Janbon noted hypoglycemia while using antibiotic para amino sulfonami...

The macrobicyclic title compound, C(23)H(35)N(3)O(8)S, contains two tertiary amide bridgehead N atoms and a toluene-sulfonamide N atom in the center of the five-atom bridging strand. The mol-ecule has a central cavity that is defined by the 18-membered ring identified by the N(2)O(4) donor atom set and two 15-membered rings with N(3)O(2) donor atom sets. The toluene-sulfonamide N atom adopts an...

www.experimentjournal.com 1254 Synthesis, biological activity and docking studies of N,N'-(3S,4S)bis(3,4-disubstituted pyrrolidine)-1-sulfonamide derivatives as β-gluscosidase inhibitors Abstract Starting with L-tartaric acid the chiral 3,4-disubstituted pyrrolidine analogue sulfonamide derivatives were prepared. These compounds were examined for anti-bacterial and anti-fungal activity. Further...
