	abstract = {A series of beta,beta-dihydroxychlorins derived from meso-tetraphenylporphyrins (TPPs) have been synthesized. Their in vitro cytotoxicity has been measured and compared to BPDMA (verteporfin). Under the assay conditions BPDMA had an LD50 (lethal dose to kill 50\% of cells) value of 0.007 muM (5 ng/mL). The LD50 values for the TPP derivatives varied from 1.7 x 10(-2) to 9.9 muM depending upon the substituents and their position on the phenyl groups. One example of the dihydroxychlorin prepared from unsubstituted 5,15-diphenylporphyrin was examined and this exhibited an LD50 of 2.4 x 10(-3) muM!

	abstract = {The Pointed (PNT) domain and an adjacent mitogen-activated protein (MAP) kinase phosphorylation site are defined by sequence conservation among a subset of ets transcription factors and are implicated in two regulatory strategies, protein interactions and posttranslational modifications, respectively. By using NMR, we have determined the structure of a 110-residue fragment of murine Ets-1 that includes the PNT domain and MAP kinase site. The Ets-1 PNT domain forms a monomeric five-helix bundle. The architecture is distinct from that of any known DNA- or protein-binding module, including the helix-loop-helix fold proposed for the PNT domain of the ets protein TEL. The MAP kinase site is in a highly flexible region of both the unphosphorylated and phosphorylated forms of the Ets-1 fragment. Phosphorylation alters neither the structure nor monomeric state of the PNT domain. These results suggest that the Ets-1 PNT domain functions in heterotypic protein interactions and support the possibility that target recognition is coupled to structuring of the MAP kinase site.},

	abstract = {The crystal structure of the low temperature form of ZSM-11 (structure code MEL) was refined from high resolution synchrotron X-ray powder diffraction data, recorded at 20 K. Based on the results of 2D Si-29 NMR investigations a model was obtained by energy minimization the Rietveld refinement of which converged in space group <I(4)over bar> (No. 82) [a = 20.019(2) Angstrom; c = 13.380(1) Angstrom] to R(I) = 0.143 and R(wp) = 0.126. Comparison of the theoretically predicted and experimentally determined structures against results from NMR experiments using the average T-T distance relationship between the structural parameters and the isotropic Si-29 chemical shifts did not show any correlation with the results of the structure refinement. However, with the values obtained from the energy-minimized structure model a good correlation between the structural parameters and the chemicals shifts of Si was obtained for one of the two possible assignments of the NMR chemical shifts to Si-sites. The fit of the energy minimized model to the experimental data set gave R(I) = 0.179 and R(wp) = 0.157. Since the NMR experiment gives direct information about the local ordering and structural state of the material this demonstrates the potential of the modeling experiment and also reveals the limits in accuracy and precision of the Rietveld structure refinement.},
