[PMID: 37480812 DOI: 10.1016/j.bioorg.2023.106741] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2023] [Revised: 07/06/2023] [Accepted: 07/16/2023] [Indexed: 07/24/2023]
Abstract
The aim of the present study was to investigate the small molecule anticancer agents in the medicinal fungus Inonotus obliquus and further characterize their possible molecular mechanisms. Chemical fractionation of the ethanol extract of this fungus yielded a panel of lanostane triterpenoids (1-13) and their structures were characterized on the basis of spectroscopic methods. Subsequent preliminary biological screening on these triterpenoids revealed significant cytotoxicity against various tumor cell lines, and inonotsutriol E (ITE, 1) showed the best activity. Of note, ITE displayed stronger inhibitory effect on breast cancer (BC) than other tumor cell lines. Functional assays revealed that ITE significantly inhibited the growth and migration of BC cells and exerted promising antitumor activity in patient-derived organoids (PDO). Further mechanistic study demonstrated that the anti-BC activity of ITE was achieved via inhibiting JAK2/STAT3 signal axis. Taken together, the current work has demonstrated the therapeutic material basis of I. obliquus and provided further evidence for the traditional application of this medicinal species in cancer prevention and treatment.

Dithiocarbazate ligands and their Ni(II) complexes with potential biological activity: Structural, antitumor and molecular docking study. Front Mol Biosci 2023; 10:1146820. [PMID: 36968279 PMCID: PMC10034969 DOI: 10.3389/fmolb.2023.1146820] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2023] [Accepted: 02/14/2023] [Indexed: 03/09/2023] Open
Abstract
In the search for new metal complexes with antitumor potential, two dithiocarbazate ligands derived from 1,1,1-trifluoro-2,4-pentanedione (H2L1) and (H2L2) and four Ni(II) complexes, [Ni(L1)PPh3] (1), [Ni(L1)Py] (2), [Ni(L2)PPh3] (3), and [Ni(L2)Py] (4), were successfully synthesized and investigated by physical-chemistry and spectroscopic methods. The crystal structure of the H2L1 and the Ni(II) complexes has been elucidated by single-crystal X-ray diffraction. The obtained structure from H2L1 confirms the cyclization reaction and formation of the pyrazoline derivative. The results showed square planar geometry to the metal centers, in which dithiocarbazates coordinated by the ONS donor system and a triphenylphosphine or pyridine molecule complete the coordination sphere. Hirshfeld surface analysis by dnorm function was investigated and showed π–π stacking interactions upon the molecular packing of H2L1 and non-classical hydrogen bonds for all compounds. Fingerprint plots showed the main interactions attributed to H⋅H C⋅H, O⋅H, Br⋅H, and F⋅H, with contacts contributing between 1.9% and 38.2%. The mass spectrometry data indicated the presence of molecular ions [M + H]+ and characteristic fragmentations of the compounds, which indicated the same behavior of the compounds in solution and solid state. Molecular docking simulations were studied to evaluate the properties and interactions of the free dithiocarbazates and their Ni(II) complexes with selected proteins and DNA. These results were supported by in vitro cytotoxicity assays against four cancer cell lines, showing that the synthesized metal complexes display promising biological activity.

Abstract
Medulloblastoma is the most frequent malignant brain tumor in childhood, but it may also affect infants, adolescents, and young adults. Recent advances in the understanding of the disease have shed light on molecular and clinical heterogeneity, which is now reflected in the updated WHO classification of brain tumors. At the same time, it is well accepted that preclinical research and clinical trials have to be subgroup-specific. Hence, valid models have to be generated specifically for every medulloblastoma subgroup to properly mimic molecular fingerprints, clinical features, and responsiveness to targeted therapies. This review summarizes the availability of experimental medulloblastoma models with a particular focus on how well these models reflect the actual disease subgroup. We further describe technical advantages and disadvantages of the models and finally point out how some models have successfully been used to introduce new drugs and why some medulloblastoma subgroups are extraordinary difficult to model.
