Effects of BMY 25282, a mitomycin C analogue, in mitomycin C-resistant human colon cancer cells.
BMY 25282, a newly designed analogue of mitomycin C (MMC), was assessed for its non-cross-resistant cytotoxic and biochemical action against MMC-resistant human colon carcinoma cells. The analogue has an amidine substituted at position 7 of MMC and has a more efficient intracellular activation to its active species than MMC. In this study we demonstrated that BMY 25282 can overcome MMC resistan...
متن کاملHyperthermic enhancement of cell killing by mitomycin C in mitomycin C-resistant Chinese hamster ovary cells.
The interaction of hyperthermia and mitomycin C (MMC) was studied in wild-type Chinese hamster ovary cells and in Chinese hamster ovary cells selected for resistance to MMC. Hyperthermic potentiation of MMC activity was maximal if heating was done simultaneously, or up to 3 h following MMC exposure. Heat enhanced the effect of MMC in both drug-sensitive and -resistant cells. Dose enhancement ra...
متن کاملMitomycin resistance in mammalian cells expressing the bacterial mitomycin C resistance protein MCRA.
The mitomycin C-resistance gene, mcrA, of Streptomyces lavendulae produces MCRA, a protein that protects this microorganism from its own antibiotic, the antitumor drug mitomycin C. Expression of the bacterial mcrA gene in mammalian Chinese hamster ovary cells causes profound resistance to mitomycin C and to its structurally related analog porfiromycin under aerobic conditions but produces littl...
متن کامل[Mitomycin C and excimer laser].
Mitomycin C is an antimetabolite agent that blocks DNA and RNA replication and protein synthesis. It has been used in several ophthalmologic areas, and recently as a modulator of corneal wound healing in excimer laser surgeries. A single application of mitomycin C during surface corneal photoablative surgery seems a safe and efficient therapeutic option for eyes with corneal opacity and/or as p...
متن کاملMitomycin-C Use in Ophthalmology
Mitomycin-C is a chemotherapeutic drug that acts by inhibiting DNA synthesis. Its use and application in ophthalmology has been increasing in recent years because of its mandatory effects on wound healing. Current applications include pterygium surgery, glaucoma surgery, corneal refractive surgery, cictracial eye disease, conjunctivalneoplasia, dacryocystorhinostomy surgeries and allergic eye d...
