According to Dr. Mihael Polymeropoulos, co-founder and CEO of Vanda Pharmaceuticals, there are 10 years of substantial evidence that chloroquine attacks corona viruses. The attack is twofold: by inhibiting penetration of a host cell and if a cell is penetrated by interfering with virus replication.
Dr. Polymeropoulos does not go into detail but corona viruses attack a host cell via lysosome organelles in the host cell’s wall. Chloroquine inhibits penetration of the host cell by raising the pH (lowering the acidity) of the lysosomes. Since corona viruses require a higher lysome acidity to penetrate they are prevented from injecting their RNA into the host cell. Evidently the higher pH also causes the virus to be trapped by the lysosome and it eventually disintegrates.
Once a virus cell’s RNA enters a host cell it hijacks the cell’s ribosomes to create an enzyme that functions to replicate the original virus by the millions. Any Zn(2+) zinc ions present inside the cell inhibit replication but zinc ions cannot enter a cell unless there is some sort of transport mechanism. Chloroquine aids the transport of Zn(2+) zinc ions to the inside of a cell.
