Definitions
- the present invention relates to an active oxygen scavenger containing a pterin derivative.
- the present invention also relates to a pharmaceutical composition or a cosmetic composition containing the above pterin derivative.
- ischemic disorders eg, ischemic heart disease sequelae, cerebral infarction sequelae, or stress ulcers
- recanal flow disorders e.g, inflammatory diseases (eg, chronic rheumatism, nephritis, or asthma)
- inflammatory diseases eg, chronic rheumatism, nephritis, or asthma
- Cancer diabetes, cataract, arteriosclerosis, drug poisoning, pesticide poisoning, liver damage due to overdose of drugs, liver damage due to overdose of pesticides, retinopathy of prematurity, photosensitivity, or radiation damage .
- SOD super 1-year-old xydismutase
- SOD is because there is a very short in vivo half-life, a child and a mosquito? Need large amounts of administration.
- enzymes are proteins, they have antigenicity, and when long-term administration is necessary, it is necessary to consider side effects such as anaphylactic shock due to antigen-antibody reactions.
- various problems such as inability to obtain an effect by oral administration were found.
- a pterin derivative As a non-protein compound having a scavenging effect on active oxygen, a pterin derivative is known.
- JP-A-6-56669 describes that a pterin derivative or a neopterin derivative has an active oxygen scavenging effect.
- Japanese Patent Application Laid-Open No. 7-188232 describes that the same pterin derivative or neopterin derivative as described above is effective for cell damage caused by free radicals.
- Neobte which is a typical compound of the above-mentioned pterin derivative or neopterin derivative
- Phosphorus ie, 2-amino-4-oxo-1 6 _ (D-erythro-1,1, 2, 3, 2, 1-trihydroxypropyl) 1-pteridine: NP] is produced by macrophage.
- active oxygen for example, S. Kojima et al., FEBS, 304, 2, 3, 163—166, 1992; S. Kojima et al., FEBS, 329, 1, 2, 125—128, 1993].
- NFH4 5,6,7,8-tetrahydroneopterin
- R 1 and R 2 are each independently a hydrogen atom, an alkyl having 1 to 4 carbon atoms
- X is a formyl group or a hydroxymethyl group
- A is a group represented by the formula (I), or a group represented by the formula R 3 —CO— (R 3 is an alkyl group having 1 to 4 carbon atoms).
- n is a force that is 0 or an integer of 1 or more; ', provided that when X is a hydroxymethyl group, n is 0, and n is an integer of 1 or more.
- R 1 and R 2 are each a hydrogen atom, and X is a formyl group.
- the present invention provides a pharmaceutical composition, comprising a pterin derivative represented by the above formula (I), a cyclic body thereof, or a pharmaceutically acceptable salt thereof as an active ingredient.
- the present invention relates to a cosmetic composition
- a cosmetic composition comprising the pterin derivative represented by the above formula (I), or a cyclic body thereof, or a salt thereof.
- FIG. 1 is a graph showing the active oxygen quenching activity of 6-formyluputerin in the PMN-PMA system as a function of the integrated luminescence of active oxygen.
- FIG. 2 is a graph showing the results measured by low-temperature electron spin resonance when 6-formyl-pterin is added to a potassium superoxide solution in DMSO.
- FIG. 3 is a photomicrograph of a cerebral hippocampal region tissue section of a completely normal murine rat without blood flow blockage.
- FIG. 4 is a micrograph of a hippocampal region tissue section of a control group of a sand rat transient cerebral ischemia model.
- FIG. 5 is a micrograph of a tissue section of the hippocampus region of the 6-formyl-pterin-administered group in a murine transient cerebral ischemia model.
- the active oxygen scavenger of the present invention contains a pterin derivative represented by the above formula (I) as an active ingredient.
- the alkyl group having 1 to 4 carbon atoms represented by R 1 , R 2 , and R 3 is a linear or branched alkyl group having 1 to 4 carbon atoms, for example, a methyl group, an ethyl group, It is an n-propyl group, an i-propyl group, an n-butyl group, an i-butyl group, a sec-butyl group, or a tert-butyl group, and a methyl group or an ethyl group is preferable.
- R 1 and R 2 are each independently a hydrogen atom or a different hydrogen atom, the alkyl group having 1 to 4 carbon atoms, or the formula R 3 —CO — (R 3 is the above-mentioned alkyl group having 1 to 4 carbon atoms).
- n is 0 or an integer of 1 or more, preferably 0 or an integer of 1 to 100, more preferably 0 or an integer of 1 to 10.
- R 1 and R 2 are each independently a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, or a formula R : i —CO—
