Antiviral Agents: Discovery to Resistance

Abstract: In the midst of the SARS-CoV-2/Covid-19 outbreak the need for research into, and development of, antiviral agents is brought into sharp focus worldwide for scientists, governments and the public alike [...]

“…More than 1 y into the pandemic, our understanding of how SARS-CoV-2 infection affects transplant recipients has increased, but many unanswered questions remain. Hospitalization is reported in 66%-87% and mortality varies widely from 3.0% to 18.7%, [1][2][3][4][5][6][7][8][9][10][11] depending on the population studied, increasing up to 40% in those with severe disease. 12,13 Much of the literature remains focused toward hospitalized patients rather than the full spectrum of COVID-19 in transplant recipients and is limited by relatively short duration of follow-up for a disease, which we now understand can have a protracted clinical course.…”

“…Its viability as a treatment for SARS-COV-2 is in controversy [ 17 ]. Viruses can tolerate drugs after being exposed to them for a period due to viral mutations [ 18 ]. Therefore, development of new and more effective broad-spectrum antiviral drugs will improve the ability to handle future outbreaks caused by emerging and re-emerging viruses.…”

“…En el análisis estructural y funcional de la Microvirina, de Souza et al (2016) demostraron que la misma puede ser potenciable en cuanto a sus actividades antivirales (neutralizantes), mediante ciertos cambios puntuales en algunos aminoácidos que dotarían a la misma de mayor rigidez a la estructura. Un estudio llevado a cabo con una variante modificada de la Microvirina (LUMS1), evidencia dicha potencialización en las actividades neutralizantes en los virus del HIV-1 y el virus de la Hepatitis C (HCV), este ensayo se realizó in vitro con células TZM-bl, HEK293 T y HepG2, demostrando que esta variante de Microvi-rina no presenta actividad inmunogénica, de igual manera esta actividad antiviral se da por la formación de un complejo de acoplamiento también con las glicoproteínas virales gp120, evitando el reconocimiento del virus con células dianas (Adamson, 2020;Mitchell et al, 2017;Shahid et al, 2020).…”

“…Entre estos inhibidores de bajo peso molecular se encuentran las lectinas, conocidas por su capacidad de interactuar irreversiblemente con carbohidratos, glicoproteínas o con proteínas, que se encuentran en las superficies de las membranas, confiriéndoles actividad aglutinante, sin presentar actividad catalítica, es por esto que desde las últimas décadas son investigadas exhaustivamente (Kulandaivel et al, 2015;Nilsson, 2011;Singh et al, 2017). Esto permite a las lectinas bloquear interacciones intercelulares, uniéndose a los receptores proteicos como ligandos, y le provee actividad antiviral evidenciada en varios estudios, cobrando de esta manera protagonismo para áreas como la fármacología, la biotecnología y la medicina (Adamson, 2020;Nilsson, 2011;Rüdiger & Gabius, 2001;Singh et al, 2017).…”
