Improvement of the solubility of a sulfonylurea derivative for pharmaceuticals
Improvement of the solubility of a sulfonylurea derivative for pharmaceuticals. (Arzneimittel, Rentschler, Dr., G.m.b.H. und Co., Fed. Rep. Ger.). Ger. Offen. DE 3228384 A1 9 Feb 1984, 8 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: A61K031-64. APPLICATION: DE 82-3228384 29 Jul 1982.Several substances with their cas registry numbers 9004-34-6 and 7631-86-9 may be metioned in this study. DOCUMENT TYPE: Patent CA Section: 63 (Pharmaceuticals) The soly. of glibenclamide (I) [10238-21-8] is increased by converting it to a noncryst. form in the presence of sugar alcs., SiO2, cellulose [9004-34-6] and its derivs., nonionic emulsifiers, poly(vinylpyrrolidone) [9003-39-8], or vinyl acetate-vinylpyrrolidone copolymer [25086-89-9]. Thus, 2 parts I was stirred into 10 parts warm polyethylene glycol-20 sorbitan monostearate [9005-67-8], 50 g xylitol [87-99-0] was added, and the temp. was increased until the mixt. was clear. On cooling, the mixt. solidified and was ground to give noncryst. I with a soly. of 95 mg/mL. .

Ed., 14(10), 2545-52 (English) 1976. CODEN: JPLCAT. DOCUMENT TYPE: Journal CA Section: 35 (Synthetic High Polymers) Stable vinyl acetate macroradicals (I), produced by polymn. in a nonviscous poor solvent, a viscous good solvent, and a viscous poor solvent, were reacted with a second vinyl monomer to produce block copolymers. Good yields of block copolymer [25213-29-0] was not obtained by heating styrene with I, presumably because of chain transfer, but good yields of block copolymers were obtained with methyl methacrylate [25085-00-1], acrylic acid [24980-58-3], vinylpyrrolidone [25086-89-9], acrylonitrile [24980-62-9], and methyl acrylate [25067-63-4]. The rate of formation of I and block copolymers was fastest in viscous good and viscous poor solvents. The solvent-extd. block copolymers were characterized by yield, pyrolysis gas chromatog.Except for chemicals metioned above, 25067-63-4 and 24980-62-9 are also used., and differential scanning calorimetry. .
