The present invention provides crystals of (1R,3R,15E,28R,29R,30R,31R,34R,36R,39S,41R)-29,41-Difluoro-34,39-bis(sulfanyl)-2,33,35,38,40,42-hexaoxa-4,6,9,11,13,18,20,22,25,27-decaaza-34&#x3bb;,39&#x3bb;-diphosphaoctacyclo[28.6.4.10.10000]dotetraconta-5,7,9,11,15,19,21,23,25-nonaene-34,39-dione (Compound (I)) ammonium salts, Compound (I) sodium salts, or Compound (I), possessing a potential to be used as drug substance in pharmaceuticals.

Salts of compounds and crystals thereof

Salts of the compound represented by formula (I) or crystals thereof have a potential use as drug substances for pharmaceuticals. 

Salt of pentacyclic compound and crystal thereof

The present invention provides a crystal of (6S,9aS)-N-benzyl-8-({6-[3-4-ethylpiperazin-1-yl)azetidin-1-yl]pyridin-2-yl}methyl)-6-(2-fluoro-4-hydroxybenzyl)-4,7-dioxo-2-(prop-2-en-1-yl)hexahydro-2H-pyrazino[2,1-c][1,2,4]triazine-1(6H)-carboxamide. 

Crystal (6S,9aS)-N-benzyl-8-({6-[3-(4-ethylpiperazin-1-yl)azetidin-1-yl]pyridin-2-yl}methyl)-6-(2-fluoro-4-hydroxybenzyl)-4,7-dioxo-2-(prop-2-en-1-yl)hexahydro-2H-pyrazino[2,1-c][1,2,4]triazine-1(6H)-carboxamide

An organic carboxylic acid salt of 2-[(3S,4R)-1-{[2-chloro-6-(trifluoromethyl)phenyl]methyl}-3-{[1-(cyclohex-1-en-1-ylmethyl) piperidin-4-yl]carbamoyl}-4-methylpyrrolidin-3-yl]acetic acid and a crystal thereof.

Salt of pyrrolidin-3-yl acetic acid derivative and crystals thereof

The present invention provides a crystal of a 1.5 D-tartrate of a compound represented by the formula (1) having an A production inhibitory effect, characterized in that the crystal has a diffraction peak at a diffraction angle (20.2) of 23.2 in powder X-ray diffractometry; a crystal of a disulfate of the compound of the formula (1), characterized in that the crystal has a diffraction peak at a diffraction angle (20.2) of 17.1 in powder X-ray diffractometry; various other salts of the compound of the formula (1); crystal polymorphs of these salts; and the like, which are expected to be used as drug substances. 

Salt of tetrahydrotriazolopyridine derivative and crystal thereof

An amorphous object of (3E)-1-[l(s)-1-(4-fluorophenyl)ethyl]-3-[3-methoxy-4-(4methyl-1H-imidazol-1-yl)benzylidene]piperidine-2-one, which is represented by the formula (1) and has A&#x3b2;-production inhibitory activity. The amorphous object has such satisfactory properties that it has excellent solubility, is stable, does not readily become a crystalline form, and has low hygroscopicity. It is hence suitable for use in pharmaceutical preparations.

Amorphous object of cinnamide compound

The present invention provides a most suitable prodrug of a cinnamide compound. The prodrug is represented by Formula (I) wherein Rand Reach denote a C1-6 alkyl group or the like; Xdenotes a methoxy group or a fluorine atom; Y denotes a phosphono group or the like; and A denotes a cyclic lactam derivative.

Prodrug of cinnamide compound

The invention relates to crystalline 1H-Imidazo[4,5-b]pyridin-5-amine, 7-[5-[(cyclohexylmethylamino)-methyl]-1H-indol-2-yl]-2-methyl, sulfate (1:1), trihydrate, E6070, its method of preparation, and its therapeutic uses. Pharmaceutical compositions containing crystalline E6070 and a pharmaceutically acceptable carrier represent one embodiment of the invention. The invention also relates to methods for treating an inflammatory disorder, an autoimmune disorder, or a proliferative disorder comprising the step of administering to a patient in need thereof a therapeutically effective amount of crystalline E6070.

Crystalline 1H-imidazo[4,5-b]pyridin-5-amine, 7-[5-[(cyclohexylmethylamino)-methyl]-1H-indol-2-yl]-2-methyl, sulfate (1:1), trihydrate and its pharmaceutical uses
