2β-chloromethyl-2α-methylpenam-3α-carboxylic acid benzhydryl ester (CMPB) crystals having excellent stability; and a process for producing CMPB crystals which comprises (A) the step of concentrating a CMPB-containing solution, (B) the step of subjecting the resultant concentrate to column chromatography, (C) the step of concentrating a CMPB-containing fraction, and (D) the step of dissolving the resultant CMPB-containing concentrate in an ether solvent and subsequently adding a hydrocarbon solvent to this solution to precipitate CMPB crystals.
摘要:
An object of the present invention is to further enhance the antitumor effect when oxaliplatin is administered in combination with a combination drug containing tegafur, gimeracil and oteracil potassium. According to the present invention, by using oxaliplatin encapsulated in a liposome preparation, combination therapy of oxaliplatin plus a combination drug containing tegafur, gimeracil and oteracil potassium, is revealed to show remarkably enhanced antitumor effect without increasing side effects.

摘要:
An antitumor effect fortifier comprising as an active ingredient an effective amount of platinum (II) cis-oxalato(1R,2R-diaminocyclohexane) so as to enhance the antitumor activity of antitumor agent containing a therapeutically effective amount of tegafur, an amount, effective for the enhancement of antitumor effect, of gimeracil and an amount, effective for the suppression of side effects, of oteracil potassium; and a relevant antitumor agent. Further, there is provided a method of therapy for cancer, characterized in that an amount, effective for the enhancement of antitumor effect, of platinum (II) cis-oxalato(1R,2R-diaminocyclohexane) is concomitantly administered to a mammal. Still further, there is provided an antitumor agent consisting of a pharmaceutical preparation form composed of at least two separate preparations containing efficacious ingredients consisting of tegafur, gimeracil, oteracil potassium and platinum (II) cis-oxalato(1R,2R-diaminocyclohexane) each alone or in an arbitrary combination, or a pharmaceutical preparation form constituted of a single preparation containing all the efficacious ingredients. Still further, there is provided a relevant kit.
摘要:
A herpesvirus-derived therapeutic agent for pain which comprises (±)-[2-[4-(3-ethoxy-2-hydroxypropoxy)phenylcarbamoyl]ethyl]dimethylsulfonium p-toluenesulfonate of the formula (1) as an active ingredient. [Chemical formula] (1)
摘要:
The present invention provides a benzimidazole compound represented by Formula (I)
wherein X 1 is oxygen or carbonyl, and R 1 is a furan ring having 1 to 3 substituents or a pyrrole ring that may have 1 to 3 substituents; excluding compounds represented by Formula (I) wherein at least one of the substituents is a phosphoric acid group or a phosphoric ester group; or a salt thereof. The benzimidazole compound or salt thereof has excellent prostaglandin synthase inhibitory activity, and is useful as an agent for preventing and/or treating diseases in which prostaglandin D2 or metabolites thereof participates, such as allergic and inflammatory diseases, and as inhibitor for the exacerbation of Alzheimer's disease or cerebral damage.
摘要:
It is intended to provide a model animal which is useful in developing a preventive or a remedy for human chronic nonbacterial prostatitis, more specifically speaking, a nonhuman model animal of nonbacterial prostatitis having pathologic conditions simulating human chronic nonbacterial prostatitis. The above nonbacterial prostatitis model animal is constructed by injecting hydrochloric acid under the prostatic membrane and characterized by having a tissue injury characteristically observed human chronic nonbacterial prostatitis in the prostatic tissue as well as a lower urinary tract injury characteristically observed in human chronic nonbacterial prostatitis.
摘要:
Provided are a method for evaluating evenness of suplatast tosilate crystals; stable suplatast tosilate crystals exhibiting evenness in optical purity; and a method for producing the suplatast tosilate crystals. The method for evaluating evenness of suplatast tosilate crystals includes: (a) a step of adding a solvent to suplatast tosilate crystals to thereby dissolve 3% or less of the crystals in the solvent, and subjecting a portion of the supernatant of the resultant suspension to optical purity measurement, and (b) a step of adding a solvent to the remaining suspension to thereby dissolve the entirety of the suspension in the solvent, and subjecting a portion of the resultant solution to optical purity measurement, wherein the optical purity as measured in the step (a) is compared with the optical purity as measured in the step (b). The suplatast tosilate crystals exhibits excellent evenness and thermal stability. The method for producing the suplatast tosilate crystals is also provided.
