Bibliometric Analysis of Research on Boesenbergia rotunda, Pinostrobin, and Their Derivatives: Dominance of Southeast Asian Researchers

Pinostrobin, marker compounds from Boesenbergia rotunda with various pharmacological activities, have been studied extensively, including synthesizing its derivatives, which have potent pharmacological activities. This study aims to describe research related to B. rotunda, pinostrobin, and their derivatives. Metadata information was collected from Scopus in August 2022, with three keywords searched for article titles, abstracts, and keywords. Analysis and research mapping were carried out with VOSviewer. The most widely used synonym for the plant name was "Boesenbergia rotunda", in which Norzulaani Khalid from the University of Malaya, Malaysia, mostly reported research with the keywords "Boesenbergia rotunda", "pinostrobin", and "derivative". The majority of researchers come from institutions in Southeast Asia, such as Malaysia, Thailand, and Indonesia. Interestingly, no Chinese researchers have reported studies on this topic. The journals and publishers that publish the most articles with these three keywords are Bioorganic and Medicinal Chemistry Letters and Elsevier, respectively. This information will make it easier for researchers on this topic to find partners for collaboration and determine journals to publish their research results.

La pinostrobina, compuesto de marcadores de Boesenbergia rotunda con diversas actividades farmacológicas, se ha estudiado ampliamente, incluida la síntesis de sus derivados que tienen potentes actividades farmacológicas. Este estudio tuvo como objetivo describir investigaciones relacionadas con B. rotunda, pinostrobina y sus derivados. La información de metadatos se recopiló de Scopus en agosto de 2022, con tres palabras clave buscadas para títulos de artículos, resúmenes y palabras clave. El análisis y el mapeo de la investigación se realizaron con VOSviewer. El sinónimo más utilizado para el nombre de la planta fue "Boesenbergia rotunda", en el que Norzulaani Khalid de la Universidad de Malaya, Malasia, informó principalmente sobre investigaciones con las palabras clave "Boesenbergia rotunda", "pinostrobina" y "derivado". La mayoría de los investigadores provienen de instituciones del sudeste asiático como Malasia, Tailandia e Indonesia. Curiosamente, ningún investigador chino ha informado de estudios sobre este tema. Las revistas y editoriales que más artículos publican con estas tres palabras clave son Bioorganic and Medicinal Chemistry Letters y Elsevier. Esta información facilitará a los investigadores sobre este tema encontrar colaboraciones y determinar las revistas para publicar los resultados de sus investigaciones.

The coronavirus disease 2019 main protease inhibitor from Andrographis paniculata (Burm. f) Ness.

The coronavirus disease 2019 (COVID-19) pandemic has attracted worldwide attention. Andrographis paniculata (Burm. f) Ness (AP) is naturally used to treat various diseases, including infectious diseases. Its Andrographolide has been clinically observed for anti-HIV and has also in silico tested for COVID-19 main protease inhibitors. Meanwhile, the AP phytochemicals content also provides insight into the molecular structures diversity for the bioactive discovery. This study aims to find COVID-19 main protease inhibitor from AP by the molecular docking method and determine the toxicity profile of the compounds. The results obtained two compounds consisting of flavonoid glycosides 5,4'-dihydroxy-7-O-ß -D-pyran-glycuronate butyl ester and andrographolide glycoside 3-O-ß-D-glucopyranosyl-andrographolide have lower free binding energy and highest similarity in types of interaction with amino acid residues compared to its co-crystal ligands (6LU7) and Indinavir or Remdesivir. The toxicity prediction of the compounds also reveals their safety. These results confirm the probability of using AP phytochemical compounds as COVID-19 main protease inhibitors, although further research must be carried out.
