Synthesis, detailed structural characterization (X-ray, NMR, MS, IR, elemental analysis), and studies of toxicity, antioxidant activity and bioavailability of unique potent anti-atherosclerotic succinobucol-steroid conjugates are reported. The conjugates consist of, on one side, the therapeutically important drug succinobucol ([4-{2,6-di-tert-butyl-4-[(1-{[3-tert-butyl-4-hydroxy-5-(propan-2-yl)phenyl]sulfanyl}ethyl)sulfanyl]phenoxy}-4-oxo-butanoic acid]) possessing an antioxidant and anti-inflammatory activity, and on the other side, plant stanol/sterols (stigmastanol, β-sitosterol and stigmasterol) possessing an ability to lower the blood cholesterol level. A cholesterol-succinobucol prodrug was also prepared in order to enhance the absorption of succinobucol through the intestinal membrane into the organism and to target the drug into the place of lipid metabolism—The enterohepatic circulation system. Their low toxicity towards mice fibroblasts at maximal concentrations, their antioxidant activity, comparable or even higher than that of ascorbic acid as determined by direct quenching of the DPPH radical, and their potential for significantly altering total and LDL cholesterol levels, suggest that these conjugates merit further studies in the treatment of cardiovascular or other related diseases. A brief discussion of succinobucol’s ability to quench the radicals, supported with a computational model of the electrostatic potential mapped on the electron density surface of the drug, is also presented.

HDL-mediated cholesterol efflux and macrophage polarization in human THP-1 macrophages
Karttunen, Elina (2024)HDL:t (eng. high-density lipoproteins, HDLs) ovat monimuotoinen joukko lipoproteiineja, jotka välittävät useita alempaan sydän- ja verisuonitautiriskiin yhteydessä olevia toimintoja. HDL:n pääasiallinen tehtävä on kuljettaa ... -
Steroid conjugates for applications in pharmacology and biology
Jurček, Ondřej (2011)The scope of present study is rather broad and may seem to be non-uniform, covering subjects such as the treatment of insect pest species and atherosclerosis. Nevertheless, the magic word "steroid" connects the presented ... -
In Situ Formation of Steroidal Supramolecular Gels Designed for Drug Release
Bunzen, Hana; Kolehmainen, Erkki (MDPI AG, 2013)In this work, a steroidal gelator containing an imine bond was synthesized, and its gelation behavior as well as a sensitivity of its gels towards acids was investigated. It was shown that the gels were acid-responsive, ... -

Alén, Markku (1985)Eleven top-level power athletes (6 control, 5 experimental subjects) completed the prospective 42 weeks of investigation aimed to elucidate androgenic-anabolic steroid effects on endocrinology and metabolism. During the ... -
Disorder and dephasing effects on electron transport through conjugated molecular wires in molecular junctions
Nozaki, D.; Gomes da Rocha, Claudia; Pastawski, H.M.; Cuniberti, G. (American Physical Society, 2012)Understanding electron transport processes in molecular wires connected between contacts is a central focus in the field of molecular electronics. Especially, the dephasing effect causing tunneling-to-hopping transition ...
