Abstract
Xanthotoxin (XAT) is a natural furanocoumarins, a bioactive psoralen isolated from the fruit of the Rutaceae plant Pepper, which has received increasing attention in recent years due to its wide source and low cost. By collecting and compiling literature on XAT, the results show that XAT exhibits significant activity in the treatment of various diseases, including neuroprotection, skin repair, osteoprotection, organ protection, anticancer, antiinflammatory, antioxidative stress and antibacterial. In this paper, we review the pharmacological activity and potential molecular mechanisms of XAT for the treatment of related diseases. The data suggest that XAT can mechanistically induce ROS production and promote apoptosis through mitochondrial or endoplasmic reticulum pathways, regulate NF-κB, MAPK, JAK/STAT, Nrf2/HO-1, MAPK, AKT/mTOR, and ERK1/2 signaling pathways to exert pharmacological effects. In addition, the pharmacokinetics properties and toxicity of XAT are discussed in this paper, further elucidating the relationship between structure and efficacy. It is worth noting that data from clinical studies of XAT are still scarce, limiting the use of XAT in the clinic, and in the future, more in-depth studies are needed to determine the clinical efficacy of XAT.

Abstract
BACKGROUND PUVA (psoralen UVA) therapy is used to treat a variety of skin conditions, such as vitiligo psoriasis, eczema and mycosis fungoides, but it is frequently accompanied by phototoxicity leading to burning pain, itch and erythema. METHODS We used a combination of calcium and reactive oxygen species (ROS) imaging, patch clamp and neuropeptide release measurement to investigate whether certain ion channels involved in pain and itch signalling could be responsible for these adverese effects of PUVA. RESULTS Clinically used psoralen derivatives 8-methoxypsoralen (8-MOP) and 5-methoxypsoralen at physiologically relevant concentrations were able to activate and photosensitize two recombinant thermoTRP (temperature-gated Transient Receptor Potential) ion channels, TRPA1 (Transient Receptor Potential Ankyrin type 1) and TRPV1 (Transient Receptor Potential Vanilloid type 1). 8-MOP enhanced ROS production by UVA light, and the effect of 8-MOP on TRPA1 could be abolished by the antioxidant N-acetyl cysteine and by removal of critical cysteine residues from the N-terminus domain of the channel. Natively expressed mouse TRPA1 and TRPV1 both contribute to photosensitization of cultured primary afferent neurons by 8-MOP, while direct neuronal activation by this psoralen-derivative is mainly dependent on TRPV1. Both TRPA1 and TRPV1 are to a large extent involved in controlling 8-MOP-induced neuropeptide release from mouse trachea. CONCLUSIONS Taken together our results provide a better understanding of the phototoxicity reported by PUVA patients and indicate a possible therapeutic approach to alleviate the adverse effects associated with this therapy. SIGNIFICANCE Our work provides evidence for the involvement of thermoTRP channels TRPA1 and TRPV1 in the activation and photosensitization of peripheral nociceptors during PUVA (Psoralen UVA) therapy.

The active compounds derived from Psoralea corylifolia for photochemotherapy against psoriasis-like lesions: The relationship between structure and percutaneous absorption. Eur J Pharm Sci 2018; 124:114-126. [PMID: 30153523 DOI: 10.1016/j.ejps.2018.08.031] [Citation(s) in RCA: 20] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2018] [Revised: 08/07/2018] [Accepted: 08/23/2018] [Indexed: 12/16/2022]
Abstract
8‑Methoxypsoralen (8-MOP) in combination with ultraviolet A (PUVA) is a photochemotherapy for management of psoriasis. 8-MOP is a natural compound from Psoralea corylifolia. The present work was undertaken to evaluate the percutaneous absorption of five compounds derived from P. corylifolia, and to further explore the inhibitory effect on psoriasis-like lesions generated by imiquimod stimulation in a mouse model. 8-MOP, psoralen, isopsoralen, psoralidin, and bakuchiol were comparatively tested for in vitro skin permeation, keratinocyte apoptosis, and in vivo antipsoriatic potency. The pig ear skin deposition of 8-MOP, isopsoralen, and bakuchiol at an equimolar dose was 0.47, 0.58, and 0.50 nmol/mg, respectively, which was comparable and higher than that of psoralen (0.25 nmol/mg) and psoralidin (0.14 nmol/mg). Psoralidin and bakuchiol were absorbed into the skin without further penetration across the skin. Besides experimental data of physicochemical properties, the hydrogen bond number, total polarity surface, and stratum corneum lipid docking calculated could explain the correlation of the penetrant structure with the skin permeability. The antiproliferative activity against keratinocytes was stronger for 8-MOP and isopsoralen than the others. Topical application of PUVA by using 8-MOP and isopsoralen on imiquimod-induced plaque significantly reduced transepidermal water loss from 55 to 33 and 38 g/m2/h, respectively. The epidermal thickening elicited by imiquimod (117 μm) was decreased to 62 and 26 μm by 8-MOP and isopsoralen application. IL-6 expression in psoriasiform skin was downregulated by isopsoralen but not 8-MOP. Isopsoralen may be a potential candidate for PUVA therapy.
