Methods of use of medicaments having neovascularization promoting action, which medicaments comprise a retinoid antagonist such as 4-(5H-7,8,9,10-tetrahydro-5,7,7,10,10-pentamethylbenzo[e]naphtho[2,3-b][1-,4]diazepin-13-yl)benzoic acid as an active ingredient.
摘要:
A method for forming an organ and/or tissue from undifferentiated cells derived from a vertebrate animal in vitro, which comprises the step of culturing the undifferentiated cells derived from a vertebrate animal in the presence of a retinoic acid X receptor ligand (e.g., a retinoic acid X receptor agonist or antagonist), and a method for forming a pancreas from undifferentiated cells derived from a vertebrate animal in vitro or a method for forming a tissue having morphology and function of a pancreas from undifferentiated cells derived from a vertebrate in vitro, which comprises the step of culturing the undifferentiated cells derived from a vertebrate animal in the presence of a retinoic acid receptor ligand, together with activin, that does not substantially bind to the retinoic acid receptor subtype γ.
摘要:
It is an object of the present invention to provide a novel therapeutic agent for osteoporosis.HX531 is utilized, which is synthesized as a retinoid X receptor antagonist and has an activity in inhibiting a differentiation into adipocytes. Furthermore, any dosage form containing HX531 as an effective component can be used.

摘要:
A method for preparing a crystal of 4-[(5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-naphthalenyl)carbamoyl]benzoic acid having a single endothermic peak approximately at 233° C. in differential scanning calorimetry, which comprises the step of recrystallizing a crystal of 4-[(5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-naphthalenyl)carbamoyl]benzoic acid from a mixture of water and ethanol. The method enables selective preparation of type-II crystals which are stable against physical impact. The resulting crystals are free from highly toxic hexane as a residual solvent, and preferably used as an active ingredient of pharmaceuticals.
