发明人：OJO ADEOLA F; FITCH FRANK R; BUELOW MARTIN; GITTLEMAN CRAIG S; JALE SUDHAKAR R
权利人:BOC GROUP INC
摘要:Low silicon sodium X zeolite containing little or no sodium A zeolite as by-product, is prepared by direct synthesis from sodium ion-containing hydrogels, the crystallization step being carried out by maintaining the hydrogels at a temperature below about 70° C., and preferably in the range of about 50 to about 70° C. for the duration of the crystallization step. Preferably, the ratios of components in the solutions used to make the hydrogel are such that in the hydrogel the silica/alumina molar ratio will be in the range of about 2.25:1 to about 2.4:1; the sodium oxide to silica molar ratio will be in the range 1.6:1 to about 1.9:1; and the water to sodium oxide molar ratio will be greater than about 60:1.

标 题:Structure and synthesis of nitrophenyl-EGTA, a caged calcium, intermediates thereof and a method of producing a high photochemical yield of liberated calcium
发明人：ELLIS-DAVIES GRAHAM C R; KAPLAN JACK H
摘要:The synthesis and compound of a new caged calcium which is an ortho-nitrophenyl derivative of EGTA and various intermediates. It is synthesized in ten steps and 24% overall yield. The photosensitive chelator, nitrophenyl-EGTA, has a K d for Ca 2+ of 80 nM and for Mg 2+ of 8.8 mM. Upon exposure to ultra-violet light (in the region of 350 nm), the chelator is cleaved, yielding iminodiacetic acid photoproducts with known low Ca-affinity (K d =1 mM). The quantum yield of photolysis of nitrophenyl-EGTA in the presence of Ca a+ is 0.23 and in the absence of Ca 2+ is 0.20. In experiments with chemically skinned skeletal muscle fibers, a fully relaxed fiber equilibrated with nitrophenyl-EGTA:Ca 2+ complex, in the presence of physiological [Mg 2+ ] (i.e. 1.0 mM), produced maximal contraction after a single flash from a frequency doubled ruby laser (347 nm). Half-maximal tension was achieved in 18 ms at 15° C. Nitrophenyl-EGTA provides a new tool for the investigation of the mechanism of Ca 2+ -dependent physiological processes, since under conditions of normal intracellular Ca 2+ and Mg 2+ ions, only Ca 2+ ions are bound by the photolabile chelator and on illumination are released rapidly and in high photochemical yield.
