Levamisole is used as anthelmintic agent to get rid of the intestinal worms. It is (S)-(-)-enantiomer of tetramisole. This drug is used in veterinary to treat hookworm infections.  Levamisole also finds therapeutic application in the treatment of colon cancer when given in conjunction with fluorouracil.  <\/p>\n\n\n\n

(S)-enantiomer of tetramisole<\/figcaption><\/figure>\n\n\n\n

Tetramisole carries one chiral stereogenic center and exists as an enantiomeric pair. The anthelmintic activity resides in the (S)-(-)-enantiomer, levamisole. The (R)- isomer harbors undesirable side effects including vomiting. Hence the (S)-enantiomer was marketed as levamisole to replace the racemic tetramisole to treat intestinal worm infestations.<\/p>\n\n\n\n
