Strong antimicrobial activity of collinin and isocollinin against periodontal and superinfectant pathogens in vitro

Periodontitis pathogenesis involves activation of host immune responses triggered by microbial dysbiosis. Therefore, controlling periodontal pathogens in-vivo is a main goal of periodontal therapy. New antimicrobials might help to control periodontal infection and improve treatment outcomes at “the dark times” of increasing antibiotic resistance. Here, we determined the biological activity of collinin and isocollinin against 8 bacterial strains. Antimicrobial activity of collinin and isocollinin, chlorhexidine digluconate (CHX) and sodium hypochlorite (NaClO) was evaluated against clinically relevant periodontal bacteria, like Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Fusobacterium nucleatum, Prevotella intermedia, Dialister pneumosintes strains and superinfectants like Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa strains. A broth microdilution test was carried out to determine the minimum inhibitory concentration of collinin and isocollinin against those strains, and bacterial viability was determined by resazurin assay at diverse concentration and exposure times. P. gingivalis was the most susceptible strain to collinin and isocollinin (MIC 2.1 μg/mL and 4.2 μg/mL respectively). Other periodontal pathogens showed MICs 17 μg/mL for collinin and MICs between 20 and 42 μg/mL for isocollinin, whereas CHX and NaClO showed MICs of 62 and 326 μg/mL, respectively. Collinin and isocollinin also exhibited antimicrobial activity against superinfectant bacteria (MIC 21 and 42 μg/mL, respectively). Overall, collinin and isocollinin showed a remarkable antibacterial activity against relevant periodontal and superinfective bacteria, especially against P. gingivalis (MIC 2.1 μg/mL and 4.2 μg/mL respectively) and the highly virulent P. aeruginosa (MIC 5.2 and 20.8 μg/mL, respectively).

Solubility of Collinin and Isocollinin in Pressurized Carbon Dioxide: Synthesis, Solubility Parameters, and Equilibrium Measurements

Collinin is a derivative of coumarin that has shown remarkable potential against cancer, tuberculosis, periodontitis, and other prevalent diseases, and is usually extracted from plants of the Rutaceae family at a very low yield. In this work, collinin and a position-isomer herein called isocollinin were synthesized at different scales (from 1 to 50 g of precursor) by a route consisting of two parallel and two sequential chemical reactions. The isomers were characterized by 1H NMR, 13C NMR, nuclear Overhauser enhancement spectroscopy NMR, melting temperature, and melting enthalpy. For each isomer, the Hansen solubility parameters and the radius of its solubility sphere were experimentally determined by solubility tests in 15 common solvents and two solvent blends. The solubility of each isomer in pressurized CO2 was determined at 30 and 50 °C from 72.2 to 112.9 bar, by an in situ high-pressure spectrometry technique, which was validated with the anthracene-CO2 system. The solubility of both isomers in CO2 increased with pressure in the range of temperatures and pressures considered, but that of collinin exhibited an asymptotic behavior around 80.8 and 104.8 bar, at 30 and 50 °C, respectively.

Natural oxyprenylated coumarins are modulators of melanogenesis

Naturally occurring coumarins 7-isopentenyloxycoumarin, auraptene, and umbelliprenin are able to modulate the biosynthesis of melanin in murine Melan-a cells probably through the interaction with selected biological targets like estrogen receptor β and aryl hydrocarbon receptor. Such a modulation strictly depends on the individual structure of the coumarin: the presence of a 3,3-dimethylallyloxy side chain is a structural determinant for tanning activation whereas a farnesyl one leads to the opposite effect. The parent compound with a free OH group, umbelliferone, did not provide any interaction. Other coumarins assayed, having shorter chains and/or being substituted in other positions, and prenyloxypsoralens, were not active or not further investigated in this context being cytotoxic at low doses.

Synthesis of collinin, an antiviral coumarin

The synthesis of collinin, an antivirus coumarin was presented. Collinin was synthesized in three steps and 24.6% overall yield from pyrogallol and propiolic acid. The coumarin nucleas 7,8-dihydroxycoumarin was made using a concentrated H2SO4 catalyzed Pechmann-type condensation between pyrogallol and propiolic acid under solvent free conditions at 120°C for 30 minutes. The method presented an alternative and valuable route to obtain collinin for biological test purposes.
