摘要:
An object of the present invention is to provide a preventive and/or therapeutic agent for radiation damage that has a novel mechanism of action and can prevent and alleviate a wide range of symptoms of radiation damage for which no therapeutic measures have been available so far, and moreover, is highly safe to humans. A preventive and/or therapeutic agent for radiation damage comprising a compound represented by the following formula (I) such as 5-aminolevulinic acid (5-ALA) or a salt thereof as an active ingredient can be used to improve the survival rate, improve body weight reduction, and alleviate hematopoietic disorder: (wherein R 1 represents a hydrogen atom or an acyl group; and R 2 represents a hydrogen atom, a linear or branched alkyl group, a cycloalkyl group, an aryl group, or an aralkyl group).
摘要:
Provided is an antimalarial drug which is useful for prevention and treatment of infectious diseases caused by malaria parasites. A preventive and/or therapeutic agent for malaria, which contains, as an active ingredient, 5-aminolevulinic acid (ALA), a derivative thereof, or a pharmacologically acceptable salt thereof, is used.
摘要:
The object of the present invention to provide an agent effective for treating and preventing e.g. a disease caused by reduction in frataxin production. The present invention provides a frataxin enhancer comprising 5-aminolevulinic acid (ALA) or a derivative thereof or salts thereof, as well as a therapeutic and/or prophylactic agent for a disease caused by reduction in frataxin production.
摘要:
It is intended to provide an in vitro culture medium that allows the in vitro culture of fertilized eggs to progress normally to the blastocyst stage without arresting the development thereof. The normal development rate of a fertilized egg is improved by using 5-aminolevulinic acids represented by the following formula (I) (wherein R 1 represents a hydrogen atom or an acyl group, and R 2 represents a hydrogen atom, a linear or branched alkyl group, a cycloalkyl group, an aryl group, or an aralkyl group) or salts thereof as an agent for improving a normal development rate of a fertilized egg.
摘要:
Provided is a sensitizing detection agent of an oral or intravenous administration type which enables the detection of bladder cancer with a higher sensitivity without causing pain to the patient. A sensitizing detection agent for bladder cancer comprising 5-aminolevulinic acid (ALA), a derivative thereof, or a salt of these is orally or intravenously administered, and a video camera system is inserted via the urethra and a blue light at 380-440 nm is irradiated to observe the red fluorescent part. Further, VLD-M1 is inserted and a blue light at 405 nm is irradiated to observe fluorescence intensity (relative intensity) of the red light part. For oral administration, 20 mg/kg (maximum of 1 g) of ALA is dissolved in 50 mL of a 5% glucose solution prior to the administration.
摘要:
It is to provide a method for detecting urothelial cancer simply and with high accuracy. It is a method for detecting urothelial cancer comprising administering 5-aminolevulinic acid (ALA), a derivative thereof, or a salt of these to a test subject, collecting urine from the test subject, and detecting the presence of fluorescence or amount of fluorescence in the collected urine.
摘要:
[Problem to be Solved] It is an object of the present invention to provide a preventive or therapeutic composition for a therapy-resistant cancer having therapy-resistant cancer cells. [Solution] A preventive or therapeutic composition for a therapy-resistant cancer having therapy-resistant cancer cells, which is for use in photodynamic therapy, wherein the composition comprises ALAs.
摘要:
Provided is a prophylactic/therapeutic agent for influenza viral infection that is effective not only before and at an early stage of infection with influenza virus but also at an intermediate or late stage of the infection and is highly safe for human bodies. A prophylactic/therapeutic drug for influenza viral infection comprising, as active ingredients, 5-aminolevulinic acid (5-ALA), a derivative thereof or a salt of the 5-ALA or the derivative, and an iron compound is prepared. This prophylactic/therapeutic agent can be used for ameliorating (preventing) depression in food consumption, water consumption and body weight, for ameliorating (decreasing) increase in ketone body levels in blood that may otherwise cause ketosis, for ameliorating (preventing) depression in ATP levels in blood, or for ameliorating (increasing) a survival rate and depression in a body surface temperature.
