Protonation, Tautomerism, and Base Pairing of the Antiviral Favipiravir (T-705)
No full textFavipiravir (T-705) is an antiviral medication used to treat influenza. T-705 is also currently being trialled as a repurposed COVID-19 treatment. To help accelerate these efforts, this study provides important solution-phase properties of T-705 determined via computational chemistry. Density functional theory (DFT) calculations combined with the SMD continuum solvation model demonstrate that T-705 prefers the aromatic enol form in solution over the ketone tautomer. Deprotonation constants for the conjugate acids of T-705 (pKas) are then evaluated, by combining the DFT/SMD calculations with accurate G4 gas-phase basicities. These calculations indicate that T-705 is a weak base that should not significantly protonate at physiological pH. The preferential site for protonation is at the ring nitrogen ortho to the alcohol functional group (pKa ~ 7.4), followed by protonation of the oxygen on the amide side-chain at more acidic conditions (pKa ~ -9.8). Significantly, protonation of the ring nitrogen produces an acid that can deprotonate to the enol form (pKa ~ -5.1), providing a pathway for their interconversion. Finally, base-pairing of the active ribose-bound form of T-705 to cytidine and uridine is also examined. These calculations indicate that both base pairs have large binding free energies of around 4 – 5 kcal/mol, supporting previous findings that T-705 can bind with both nucleobases, leading to mis-incorporation of these pairs into viral RNA.<br /

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
