摘要:
A series of activated iodo-benzamide derivatives are described as antineoplastic and antiviral drug compounds. The compounds generally possess a chelating group, a thio trapping group and an activating group. The presumptive mechanism of action in preventing cancer cell and virus replication is through inhibition of the binding of transcription factors to zinc finger binding domains. The compounds are effective in inhibiting growth of a variety of human and animal tumor and leukemia cell lines at low concentrations.

摘要:
A pharmaceutical composition containing as active agent at least one compound selected among the group consisting of formula (I) and formula (II) and further containing at least one pharmaceutically acceptable acid. The active agent is preferably in the form of particles having a particle size smaller than 200 µm and a mean particle size of greater than 10 µm. The pharmaceutical compositions according to the invention are stabilized with at least one pharmaceutically acceptable acid. The pharmaceutical compositions are particularly useful for treatment of opportunistic infections in persons with compromised or suppressed immune systems, and in treatment of infections of trematodes.
