DOI: 10.1007/s10725-021-00712-w
Abstract: Shikonins (SK) and acetyl-shikonins (acetyl-SK) are known to possess great pharmaceutical potentials however, their ability to disrupt infectious bacterial communication system viz. quorum sensing (QS) remains unexplored. Therefore, the rationale behind this research was to… read more here.
