In addition, considering various complex diseases and/or disorders, the conjugate chemistry approach is highly acceptable and justified. Opioids have long been recognized as the most potent analgesics and serve as the basic pharmacophore for potent hybrid compounds that may be useful in pain management. However, a risk of tolerance and physical dependence exists. Since dopamine receptors have been implicated in the aforementioned adverse effects of opioids, the construction of a hybrid with dual action at opioid and dopamine receptors is of interest. Herein, we present nuclear magnetic resonance (NMR) spectroscopy and molecular dynamics simulation results for LENART01, an opioid-ranatensin hybrid peptide. Apart from molecular docking, protein-ligand interactions were also assessed in vitro using a receptor binding assay, which proved LENART01 to be bound to mu-opioid and dopamine receptors, respectively.}, keywords = {receptor binding; dopamine receptors; Biochemistry & Molecular Biology; hybrid compound}, year = {2024}, eissn = {1420-3049}, orcid-numbers = {Szeleszczuk, Lukasz/0000-0002-5302-3797} } @article{MTMT:34407138, title = {Synthesis and biochemical evaluation of 17-N-beta-aminoalkyl-4,5α-epoxynormorphinans}, url = {https://m2.mtmt.hu/api/publication/34407138}, author = {Ötvös, Ferenc and Szűcs, Edina and Urai, Ákos and Köteles, István and Szabó, Pál Tamás and Varga, Zsuzsanna Katalin and Gombos, Dávid and Hosztafi, Sándor and Benyhe, Sándor}, doi = {10.1038/s41598-023-46317-3}, journal-iso = {SCI REP}, journal = {SCIENTIFIC REPORTS}, volume = {13}, unique-id = {34407138}, issn = {2045-2322}, abstract = {Opiate alkaloids and their synthetic derivatives are still widely used in pain management, drug addiction, and abuse.

We provided evidence for the antihyperalgesic effect of CART(55-102) by inhibiting dipeptidyl-peptidase 4 (DPP4) in astrocytes and consequently reducing neuroinflammation in the rat spinal dorsal horn in a carrageenan-evoked inflammation model. Both naturally occurring CART(55-102) and CART(62-102) peptides are present in the spinal cord. CART(55-102) is not involved in acute nociception but regulates spinal pain transmission during peripheral inflammation. While the full-length peptide with a globular motif contributes to hyperalgesia, its N-terminal inhibits this process. Although the anti-hyperalgesic effects of CART(55-102), CART(55-76), and CART(62-76) are blocked by opioid receptor antagonists in our inflammatory models, but not in neuropathic Seltzer model, none of them bind to any opioid or G-protein coupled receptors. DPP4 interacts with Toll-like receptor 4 (TLR4) signalling in spinal astrocytes and enhances the TLR4-induced expression of interleukin-6 and tumour necrosis factor alpha contributing to inflammatory pain. Depending on the state of inflammation, CART(55-102) is processed in the spinal cord, resulting in the generation of biologically active isoleucine-proline-isoleucine (IPI) tripeptide, which inhibits DPP4, leading to significantly decreased glia-derived cytokine production and hyperalgesia.}, keywords = {HYPERALGESIA; chronic pain; spinal cord; Allodynia; cocaine- and amphetamine-regulated transcript (CART) peptide; dipeptidyl-peptidase-4 (DPP4)}, year = {2023}, eissn = {1422-0067}, orcid-numbers = {Kozsurek, Márk/0000-0001-5465-2803; Király, Kornél P/0000-0002-7252-0422; Szabó, Pál Tamás/0000-0003-2260-4641} } @article{MTMT:33313345, title = {The Role of a Natural Amphibian Skin-Based Peptide, Ranatensin, in Pancreatic Cancers Expressing Dopamine D2 Receptors}, url = {https://m2.mtmt.hu/api/publication/33313345}, author = {Laskowska, Anna K. and Szudzik, Mateusz and Sciezynska, Aneta and Komorowski, Michal and Szűcs, Edina and Gombos, David and Baczek, Bartlomiej and Lipka-Miciuk, Jowita and Benyhe, Sándor and Kleczkowska, Patrycja}, doi = {10.3390/cancers14225535}, journal-iso = {CANCERS}, journal = {CANCERS}, volume = {14}, unique-id = {33313345}, abstract = {Simple Summary Cancer is one of the most problematic issues worldwide, as it still requires effective therapy. Unfortunately, clinically available cancer-specific medications result in serious side effects. This is also true for pancreatic cancer which additionally is well-known for difficulties in the treatment. Therefore, the aim of the study was to evaluate the biological activity, in terms of anticancer effects, of ranatensin (RAN), a naturally existing bombesin-like peptide. For the first time, we characterized the peptide as a dopaminergic system ligand. However, despite the presence of dopamine receptors in pancreatic cancer cell lines used, RAN was found to affect cancer cells possibly through different receptors since RAN's impact on pancreatic cancer cells was not correlated with their expression level of DRD2. Nevertheless, this peptide may serve as a potential useful agent with therapeutic efficacy in cancers expressing DRD2 receptors, for which DRD2 antagonism is crucial to produce antitumor effects. Despite the progress in early diagnostic and available treatments, pancreatic cancer remains one of the deadliest cancers. Therefore, there is an urgent need for novel anticancer agents with a good safety profile, particularly in terms of possible side-effects. Recently dopaminergic receptors have been widely studied as they were proven to play an important role in cancer progression. Although various synthetic compounds are known for their interactions with the dopaminergic system, peptides have recently made a great comeback. This is because peptides are relatively safe, easy to correct in terms of the improvement of their physicochemical and biological properties, and easy to predict. This paper aims to evaluate the anticancer activity of a naturally existing peptide-ranatensin, toward three different pancreatic cancer cell lines. Additionally, since there is no sufficient information confirming the exact character of the interaction between ranatensin and dopaminergic receptors, we provide, for the first time, binding properties of the compound to such receptors.}, keywords = {Anticancer agents; Pancreatic cancer; dopamine receptors; ranatensin}, year = {2022}, eissn = {2072-6694} } @article{MTMT:33221906, title = {Discovery of kappa Opioid Receptor (KOR)-Selective D-Tetrapeptides with Improved In Vivo Antinociceptive Effect after Peripheral Administration}, url = {https://m2.mtmt.hu/api/publication/33221906}, author = {Stefanucci, Azzurra and Della, Valle Alice and Scioli, Giuseppe and Marinaccio, Lorenza and Pieretti, Stefano and Minosi, Paola and Szűcs, Edina and Benyhe, Sándor and Masci, Domiziana and Tanguturi, Parthasaradhireddy and Chou, Kerry and Barlow, Deborah and Houseknecht, Karen and Streicher, John M. and Mollica, Adriano}, doi = {10.1021/acsmedchemlett.2c00237}, journal-iso = {ACS MED CHEM LETT}, journal = {ACS MEDICINAL CHEMISTRY LETTERS}, volume = {13}, unique-id = {33221906}, issn = {1948-5875}, abstract = {Peripherally active tetrapeptides as selective kappa opioid receptor (KOR) agonists have been prepared in good overall yields and high purity following solid-phase peptide synthesis via Fmoc protection strategy.

Various doses of fentanyl, morphine, or buprenorphine were administered as pre- and/or post-treatments in rats. Necrotizing AP was induced by the intraperitoneal injection of L-ornithine-HCl or intra-ductal injection of Na-taurocholate, while intraperitoneal caerulein administration caused edematous AP. Disease severity was determined by laboratory and histological measurements. Mu opioid receptor (MOR) expression and function was assessed in control and AP animals. MOR was expressed in both the pancreas and brain. The pancreatic expression and function of MOR were reduced in AP. Fentanyl post-treatment reduced necrotizing AP severity, whereas pre-treatment exacerbated it. Fentanyl did not affect the outcome of edematous AP. Morphine decreased vacuolization in edematous AP, while buprenorphine pre-treatment increased pancreatic edema during AP. The overall effects of morphine on disease severity were negligible. In conclusion, the type, dosing, administration route, and timing of opioid treatment can influence the effects of opioids on AP severity. Fentanyl post-treatment proved to be beneficial in AP.
