pluronic/bile salt/phospholipid mixed micelles (pluronic/bs/ps-mm) drug carrier system for solubilization hydrophobic drugs was developed. a typical hydrophobic compound, pyrene, was selected as a representative hydrophobic compound to model the hydrophobic drugs. five pluronics, f68, f88, f98, f108, and f127 with different ppo chain length were studied. cmc data and solubilization capacities w...
Identification of a conserved hydrophobic cluster in partially folded bovine β-lactoglobulin at pH 2
Three additional ATPase genes, clustered in the order ahaH, ahaI, and ahaK, were found upstream of the previously characterized genes ahaECFABDG coding for the archaeal A1Ao ATPase from Methanosarcina mazei. ahaH, the first gene in the cluster, is preceded by a conserved promoter sequence. Northern blot analysis revealed that the clusters ahaHIK and ahaECFABDG are transcribed as one message. Ah...
Autonomously folding beta-hairpins have recently emerged as powerful tools for elucidating the origins of antiparallel beta-sheet folding preferences. Analysis of such model systems has suggested four potential sources of beta-sheet stability: (1) the conformational propensity of the loop segment that connects adjacent strands; (2) favorable contacts between side-chains on adjacent strands; (3)...
A series of 21 compounds isolated from Curcuma zedoaria was subjected to cytotoxicity test against MCF7; Ca Ski; PC3 and HT-29 cancer cell lines; and a normal HUVEC cell line. To rationalize the structure-activity relationships of the isolated compounds; a set of electronic; steric and hydrophobic descriptors were calculated using density functional theory (DFT) method. Statistical analyses wer...
The observed genetic alterations of various extracellular and intracellular WNT (Wingless, Int-1 proto-oncogene) signaling components can result in an increase or decrease in gene expression, and hence can be obstructed proficiently. These genetics target sites may include the prevention of WNT-FZD (Frizzled) binding, destruction of β-catenin and formation of Axin, APC and GSK-3β complex. Hence...
Arylsulphatase activity was identified in cultures of the marine bacterium Alteromonas carrageenovora, using methylumbelliferyl sulphate as substrate. In contrast with most other microbial arylsulphatases, arylsulphatase production in A. carrageenovora was not repressed by sulphate. The structural gene of arylsulphatase (atsA) was cloned and sequenced. An ORF of 984 bp was found, specifying a p...
