Physical description & handling notes

• 0.1 M Citrate buffer pH 4.3 17.1 - 25.7 (mg/mL)
• 0.1 M Borate buffer pH 9.0 8.7 - 13.0 (mg/mL)
• Bulk: A sample stored at 60 °C for 14 days showed no decomposition as indicated by UV absorption, paper chromatography, or ionic chloride determination. Solution: An aqueous solution (18 mg/mL) which was stored at 28°C for 14 days showed less than 1% decomposition by UV absorption, paper chromatography and ionic chloride measurement.

Documented Uses

• Chemical substances, produced by microorganisms, inhibiting or preventing the proliferation of neoplasms.
• Substances that destroy fungi by suppressing their ability to grow or reproduce. They differ from FUNGICIDES, INDUSTRIAL because they defend against fungi present in human or animal tissues.
• Drugs that are chemically similar to naturally occurring metabolites, but differ enough to interfere with normal metabolic pathways. (From AMA Drug Evaluations Annual, 1994, p2033)
• Antimetabolites that are useful in cancer chemotherapy.
• Compounds or agents that combine with an enzyme in such a manner as to prevent the normal substrate-enzyme combination and the catalytic reaction.
