The molecular weights of chloroquine and hydroxychloroquine are 320 and 336, respectively; so one mole of chloroquine weighs 320 g and one mole of hydroxychloroquine weighs 336 g. That would be the synthesis of chloroquine from 4,7-dichloroquinoline and 4-diethylamino-1-methylbutylamine,. Chloroquine is able to bind to DNA, and inhibit DNA replication and RNA synthesis which in turn results in cell death glutathione, total cholesterol, alanine and aspartate transaminases is summarized in Table 1.
