Mylotarg® (gemtuzumab ozogamicin for Injection) is a chemotherapy agent composed of a recombinant humanized IgG4, kappa antibody conjugated with a cytotoxic antitumor antibiotic, calicheamicin, isolated from fermentation of a bacterium, Micromonospora echinospora subsp. calichensis. The antibody portion of Mylotarg (gemtuzumab ozogamicin for injection) binds specifically to the CD33 antigen, a sialic acid-dependent adhesion protein found on the surface of leukemic blasts and immature normal cells of myelomonocytic lineage, but not on normal hematopoietic stem cells.

It is an analogue of hydrochlorothiazide and occurs as a white to practically white crystalline powder which is basically odorless. Methyclothiazide (methyclothiazide (methyclothiazide (methyclothiazide tablet 5 mg) tablet 5 mg) tablet 5 mg) is very slightly soluble in water and chloroform, and slightly soluble in alcohol. Chemically, methyclothiazide (methyclothiazide (methyclothiazide (methyclothiazide tablet 5 mg) tablet 5 mg) tablet 5 mg) is represented as 6-chloro-3-(chloromethyl)-3,4-dihydro-2-methyl-2H-1,2,4-benzothiadiazine-7-sulfonamide 1,1-dioxide. The structural formula is:

MUTAMYCIN® (mitomycin for injection, USP) (also known as mitomycin and/or mitomycin-C) is an antibiotic isolated from the broth of Streptomyces caespitosus which has been shown to have antitumor activity.
