Pterin-based pigmentation in animals.
Andrade P, Carneiro M. Andrade P, et al. Biol Lett. 2021 Aug;17(8):20210221. doi: 10.1098/rsbl.2021.0221. Epub 2021 Aug 18. Biol Lett. 2021. PMID: 34403644 Free PMC article.
Pterins are one of the major sources of bright coloration in animals. ...Crucial gaps persist in our knowledge on the molecular basis underlying the production and deposition of pterins. We thus highlight the need for functional studies on systems amenable for labor …

Pterin-lysine photoadduct: a potential candidate for photoallergy.
Farías JJ, Lizondo-Aranda P, Thomas AH, Lhiaubet-Vallet V, Dántola ML. Farías JJ, et al. Photochem Photobiol Sci. 2022 Sep;21(9):1647-1657. doi: 10.1007/s43630-022-00248-6. Epub 2022 Jun 6. Photochem Photobiol Sci. 2022. PMID: 35666464
Here, we evaluated the capability of pterin (Ptr) to form photoadducts with free Lysine (Lys) and poly-L-lysine (poly-Lys). ...On the other hand, the photoproduct formed with free Lys does not behave like Ptr, which suggests that if this product is a photoadduct, a chemica …

Pterin transport and metabolism in Leishmania and related trypanosomatid parasites.
Ouellette M, Drummelsmith J, El-Fadili A, Kündig C, Richard D, Roy G. Ouellette M, et al. Int J Parasitol. 2002 Apr;32(4):385-98. doi: 10.1016/s0020-7519(01)00346-0. Int J Parasitol. 2002. PMID: 11849635 Review.
Work on the mechanism of methotrexate resistance in Leishmania has dramatically increased our understanding of folate and pterin metabolism in this organism. The metabolic and cellular functions of the reduced form of folates and pterins are beginning to be establis …

Pterin-photosensitization of thymine under anaerobic conditions in the presence of guanine.
Estébanez S, Rivera AM, Neyra Recky JR, Thomas AH, Lhiaubet-Vallet V, Lorente C. Estébanez S, et al. Free Radic Biol Med. 2021 Oct;174:321-328. doi: 10.1016/j.freeradbiomed.2021.07.032. Epub 2021 Jul 30. Free Radic Biol Med. 2021. PMID: 34339797
Pterin (Ptr) is a model photosensitizer that acts mainly through type I mechanism and is able to photoinduce the one-electron oxidation of purine and pyrimidine nucleobases. ...

Pterin metabolism, inflammation and oxidative stress biochemical markers in schizophrenia: Factor analysis and assessment of clinical symptoms associations.
Zhilyaeva TV, Kasyanov ED, Rukavishnikov GV, Piatoikina AS, Bavrina AP, Kostina OV, Zhukova ES, Shcherbatyuk TG, Mazo GE. Zhilyaeva TV, et al. Prog Neuropsychopharmacol Biol Psychiatry. 2023 Dec 20;127:110823. doi: 10.1016/j.pnpbp.2023.110823. Epub 2023 Jul 13. Prog Neuropsychopharmacol Biol Psychiatry. 2023. PMID: 37437837
Results: Significant correlations were found within groups of pterin metabolism, inflammatory markers and redox-imbalance, and also between separate inflammation, oxidative stress and markers of pterin metabolism. The performed factor analysis made it possible to di …

Excited flavin and pterin coenzyme molecules in evolution.
Kritsky MS, Telegina TA, Vechtomova YL, Kolesnikov MP, Lyudnikova TA, Golub OA. Kritsky MS, et al. Biochemistry (Mosc). 2010 Oct;75(10):1200-16. doi: 10.1134/s0006297910100020. Biochemistry (Mosc). 2010. PMID: 21166638 Review.
Excited flavin and pterin molecules are active in intermolecular energy transfer and in photocatalysis of redox reactions resulting in conservation of free energy. ...

Pterin-based small molecule inhibitor capable of binding to the secondary pocket in the active site of ricin-toxin A chain.
Saito R, Goto M, Katakura S, Ohba T, Kawata R, Nagatsu K, Higashi S, Kurisu K, Matsumoto K, Ohtsuka K. Saito R, et al. PLoS One. 2022 Dec 12;17(12):e0277770. doi: 10.1371/journal.pone.0277770. eCollection 2022. PLoS One. 2022. PMID: 36508422 Free PMC article.
However, no attempt has been successful. In the present study, we synthesized pterin-7-carboxamides with tripeptide pendants and found that one of them interacts with both pockets simultaneously to exhibit good RTA inhibitory activity. ...

Silver cluster interactions with Pterin: Complex structure, binding energies and spectroscopy.
Buglak AA, Kononov AI. Buglak AA, et al. Spectrochim Acta A Mol Biomol Spectrosc. 2022 Oct 15;279:121467. doi: 10.1016/j.saa.2022.121467. Epub 2022 Jun 6. Spectrochim Acta A Mol Biomol Spectrosc. 2022. PMID: 35689845
SERS detection of pterin is better to be done at pH > 8 since deprotonated pterin Raman undergo more dramatic changes upon addition of Ag than the neutral pterin. The characteristics of absorption and vibrational spectra of silver-pterin should be e …
