(NTP, 1992) Methoxsalen is 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. It has a role as a dermatologic drug, an antineoplastic agent, a photosensitizing agent, a cross-linking reagent and a plant metabolite. It is a member of psoralens and an aromatic ether. It is functionally related to a psoralen. 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 is a Photoactivated Radical Generator and Psoralen. The mechanism of action of methoxsalen is as a Photoabsorption. The physiologic effect of methoxsalen is by means of Photosensitizing Activity. Methoxsalen is a natural product found in Ammi visnaga, Zanthoxylum mayu, and other organisms with data available. Methoxsalen is a naturally occurring substance isolated from the seeds of the plant Ammi majus with photoactivating properties. As a member of the family of compounds known as psoralens or furocoumarins, methoxsalens exact mechanism of action is unknown; upon photoactivation, methoxsalen has been observed to bind covalently to and crosslink DNA. (NCI04) Methoxsalen is only found in individuals that have used or taken this drug. It is 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. After activation Methoxsalen binds preferentially to the guanine and cytosine moieties of DNA, leading to cross-linking of DNA, thus inhibiting DNA synthesis and function. 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.

Psoralen
Psoralen is 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. It has a role as a plant metabolite. 8-methoxsalen and 5-methoxsalen are furocoumarins referred to collectively as psoralens that have photosensitizing activity and are used orally and topically in conjunction with ultraviolet irradiation for the therapy of psoriasis and vitiligo. Psoralens have been linked to a low rate of transient serum enzyme elevations during therapy and to rare instances of clinically apparent acute liver injury. Psoralen is a natural product found in Cullen cinereum, Ficus erecta var. beecheyana, and other organisms with data available. Psoralen is a furocoumarin that intercalates with DNA, inhibiting DNA synthesis and cell division. Psoralen is used in Photochemotherapy with high-intensity long-wavelength UVA irradiation. Psoralens are tricyclic furocumarins and have a strong tendency to intercalate with DNA base pairs. Irradiation of nucleic acids in the presence of psoralen with long wave UV (~360 nm) results in the 2+2 cyclo- addition of either of its two photoreactive sites with 5,6-carbon bonds of pyrimidines resulting in crosslinking double-stranded nucleic acids. Psoralen is found in carrot. Psoralen is found in common vegetables, e.g. parsnip, celery especially if diseased or `spoiled Psoralen is a significant mutagen and is used for this purpose in molecular biology research.Psoralen has been shown to exhibit anti-proliferative, anti-allergenic and anti-histamine functions (A7781, A7782, A7782).Psoralen belongs to the family of Furanocoumarins. These are polycyclic aromatic compounds containing a furan ring fused to a coumarin moeity. A naturally occurring furocoumarin, found in PSORALEA. After photoactivation with UV radiation, it binds DNA via single and double-stranded cross-linking. See also: Angelica keiskei top (part of); Cullen corylifolium fruit (part of). Psoralen, also known as psoralene, ficusin or manaderm, belongs to the class of organic compounds known as psoralens. These are organic compounds containing a psoralen moiety, which consists of a furan fused to a chromenone to for 7H-furo[3,2-g]chromen-7-one. Psoralen is the parent compound in a family of naturally occurring organic compounds known as the linear furanocoumarins. Psoralen is structurally related to coumarin by the addition of a fused furan ring and is considered as a derivative of umbelliferone. Biosynthetically, psoralen originates from coumarins in the shikimate pathway. Psoralen is produced exclusively by plants but can be found in animals that consume these plants. Psoralen can be found in several plant sources with Ficus carica (the common fig) being probably the most abundant source of psoralens. They are also found in small quantities in Ammi visnaga (bisnaga), Pastinaca sativa (parsnip), Petroselinum crispum (parsley), Levisticum officinale (lovage), Foeniculum vulgare (fruit, i.e., Fennel seeds), Daucus carota (carrot), Psoralea corylifolia (babchi), Apium graveolens (celery), and bergamot oil (bergapten, bergamottin). Psoralen is found in all citrus fruits. Psoralen is a well-known mutagen and is used for this purpose in molecular biology research. Psoralen intercalates into DNA and on exposure to ultraviolet (UVA) radiation can form monoadducts and covalent inter-strand cross-links (ICL) with thymines in the DNA molecule. Psoralen also functions as a drug. An important use of psoralen is in the treatment for skin problems such as psoriasis and, to a lesser extent, eczema and vitiligo. This treatment takes advantage of the high UV absorbance of psoralen. In treating these skin conditions psoralen is applied first to sensitise the skin, then UVA light is applied to clean up the skin problem. Psoralen has also been recommended for treating alopecia. 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.

Vecuronium
Monoquaternary homolog of pancuronium. A non-depolarizing neuromuscular blocking agent with shorter duration of action than pancuronium. Its lack of significant cardiovascular effects and lack of dependence on good kidney function for elimination as well as its short duration of action and easy reversibility provide advantages over, or alternatives to, other established neuromuscular blocking agents.

Hydroxyurea
Hydroxyurea is only found in individuals that have used or taken this drug. It is an antineoplastic agent that inhibits DNA synthesis through the inhibition of ribonucleoside diphosphate reductase. [PubChem]Hydroxyurea is converted to a free radical nitroxide (NO) in vivo, and transported by diffusion into cells where it quenches the tyrosyl free radical at the active site of the M2 protein subunit of ribonucleotide reductase, inactivating the enzyme. The entire replicase complex, including ribonucleotide reductase, is inactivated and DNA synthesis is selectively inhibited, producing cell death in S phase and synchronization of the fraction of cells that survive. Repair of DNA damaged by chemicals or irradiation is also inhibited by hydroxyurea, offering potential synergy between hydroxyurea and radiation or alkylating agents. Hydroxyurea also increases the level of fetal hemoglobin, leading to a reduction in the incidence of vasoocclusive crises in sickle cell anemia. Levels of fetal hemoglobin increase in response to activation of soluble guanylyl cyclase (sGC) by hydroxyurea-derived NO.

2,6-Diamino-4-hydroxy-5-N-methylformamidopyrimidine
2,6-Diamino-4-hydroxy-5-N-methylformamidopyrimidine is a methylated derivative of 2,6-Diamino-4-hydroxy-5-N-formamidopyrimidine or FapyGua. It is produced by DNA-formamidopyrimidine glycosylase (EC 3.2.2.23). This enzyme catalyzes the hydrolysis of DNA containing ring-opened 7-methylguanine residues, releasing 2,6-diamino-4-hydroxy-5-(N-methyl)formamidopyrimidine. More specifically, this enzyme catalyzes the removal of oxidized purine bases by cleaving the N-C1 glycosidic bond between the oxidized purine and the deoxyribose sugar. The reaction involves the formation of a covalent enzyme substrate intermediate. Release of the enzyme and free base by a beta-elimination or a beta, gamma-elimination mechanism results in the cleavage of the DNA backbone 3 of the apurinic (AP) site. The presence of this compound in urine is indicative of oxidative damage to DNA (oxidized purine base lesions) [HMDB] 2,6-Diamino-4-hydroxy-5-N-methylformamidopyrimidine is a methylated derivative of 2,6-Diamino-4-hydroxy-5-N-formamidopyrimidine or FapyGua.
