Abstract
This chapter deals with the marine biopharmaceutical compounds acting
against SARS-CoV-2. The promising compounds derived for anti-coronal activity were
from marine plants such as cyanobacteria (blue-green algae), green algae, brown algae,
and red algae. Among marine invertebrates, only sponges and soft corals contributed
with their active bioactive compounds. The chemistry and mechanism of action of the
different bioactive compounds have also been dealt with.
