5-methoxypsoralen 5-Methoxypsoralen: A linear furanocoumarin that has phototoxic and anti-inflammatory properties, with effects similar to METHOXSALEN. It is used in PUVA THERAPY for the treatment of PSORIASIS.. 5-methoxypsoralen : A 5-methoxyfurocoumarin that is psoralen substituted by a methoxy group at position 5. | 2.37 | 2 | 0 | 5-methoxyfurocoumarin; organic heterotricyclic compound; psoralens | hepatoprotective agent; plant metabolite |
methoxsalen Methoxsalen: A naturally occurring furocoumarin compound found in several species of plants, including Psoralea corylifolia. It is a photoactive substance that forms DNA ADDUCTS in the presence of ultraviolet A irradiation.. methoxsalen : A member of the class of psoralens that is 7H-furo[3,2-g]chromen-7-one in which the 9 position is substituted by a methoxy group. It is a constituent of the fruits of Ammi majus. Like other psoralens, trioxsalen causes photosensitization of the skin. It is administered topically or orally in conjunction with UV-A for phototherapy treatment of vitiligo and severe psoriasis. | 3.06 | 5 | 0 | aromatic ether; psoralens | antineoplastic agent; cross-linking reagent; dermatologic drug; photosensitizing agent; plant metabolite |
trioxsalen Trioxsalen: Pigmenting photosensitizing agent obtained from several plants, mainly Psoralea corylifolia. It is administered either topically or orally in conjunction with ultraviolet light in the treatment of vitiligo.. lactone : Any cyclic carboxylic ester containing a 1-oxacycloalkan-2-one structure, or an analogue having unsaturation or heteroatoms replacing one or more carbon atoms of the ring.. antipsoriatic : A drug used to treat psoriasis.. trioxsalen : 7H-Furo[3,2-g]chromen-7-one in which positions 2, 5, and 9 are substituted by methyl groups. Like other psoralens, trioxsalen causes photosensitization of the skin. It is administered orally in conjunction with UV-A for phototherapy treatment of vitiligo. After photoactivation it creates interstrand cross-links in DNA, inhibiting DNA synthesis and cell division, and can lead to cell injury; recovery from the cell injury may be followed by increased melanisation of the epidermis. | 2.66 | 3 | 0 | psoralens | dermatologic drug; photosensitizing agent |
bromodeoxyuridine Bromodeoxyuridine: A nucleoside that substitutes for thymidine in DNA and thus acts as an antimetabolite. It causes breaks in chromosomes and has been proposed as an antiviral and antineoplastic agent. It has been given orphan drug status for use in the treatment of primary brain tumors. | 1.97 | 1 | 0 | pyrimidine 2'-deoxyribonucleoside | antimetabolite; antineoplastic agent |
ficusin Ficusin: A naturally occurring furocoumarin, found in PSORALEA. After photoactivation with UV radiation, it binds DNA via single and double-stranded cross-linking.. psoralen : The simplest member of the class of psoralens that is 7H-furo[3,2-g]chromene having a keto group at position 7. It has been found in plants like Psoralea corylifolia and Ficus salicifolia. | 1.96 | 1 | 0 | psoralens | plant metabolite |
imperatorin imperatorin: tumor necrosis factor antagonist; furanocoumarin from West African medicinal plant Clausena anisata; structure in Negwer, 5th ed, #3005. imperatorin : A member of the class of psoralens that is psoralen substituted by a prenyloxy group at position 8. Isolated from Angelica dahurica and Angelica koreana, it acts as a acetylcholinesterase inhibitor. | 1.96 | 1 | 0 | psoralens | EC 3.1.1.7 (acetylcholinesterase) inhibitor; metabolite |
angelicin angelicin: used as tranquillizer; sedative; or anticonvulsant; structure | 2.88 | 4 | 0 | furanocoumarin | |

3-carbethoxypsoralen [no description available] | 2.37 | 2 | 0 | ethyl ester; psoralens | |
4,4'-dimethylangelicin 4,4'-dimethylangelicin: structure given in first source | 2.37 | 2 | 0 | furanocoumarin | |
4-methylangelicin [no description available] | 2.66 | 3 | 0 | | |
pyrimidine dimers Pyrimidine Dimers: Dimers found in DNA chains damaged by ULTRAVIOLET RAYS. They consist of two adjacent PYRIMIDINE NUCLEOTIDES, usually THYMINE nucleotides, in which the pyrimidine residues are covalently joined by a cyclobutane ring. These dimers block DNA REPLICATION. | 2.37 | 2 | 0 | | |
hydroxymethyltrioxsalen [no description available] | 2.37 | 2 | 0 | | |
4,4',6-trimethylangelicin 4,4',6-trimethylangelicin: new monofunctional furocoumarin; potential agent for photochemotherapy of psoriasis; capable of photoreacting with DNA to a large extent forming only monoadducts; produces singlet oxygen to an insignificant extent; structure given in first source | 1.96 | 1 | 0 | furanocoumarin | |
