It is an anti-covid-19 drug, created by the nuria Monserrat team of the Institute of Bioengineering of Catalonia in collaboration with other Swedish, Austrian and Canadian scientists. I think it consists of the genetic alteration of the ACE2 protein that the coronavirus uses to enter the cells, that is, they would spoil the lock whose key uses the crown. I believe that scientists use CRISPR techniques (grouped and regularly interspaced short palindromic clusters) to alter the DNA sequences of the ACE2 protein.
