Synthesis, characterization, and antitumor activity of 5-iodouracil complexes

Area of Science:

• Inorganic Chemistry
• Medicinal Chemistry
• Cancer Research

Background:

• 5-iodouracil (5IU) is a modified nucleobase with potential biological applications.
• Metal complexes are explored for their diverse pharmacological properties, including anticancer effects.

Purpose of the Study:

• To synthesize and characterize novel metal complexes of 5-iodouracil (5IU) with various transition metal ions.
• To evaluate the in vitro and in vivo antitumor activity of these synthesized complexes against Sarcoma-180 (S-180) and L 929 tumor cell lines.

Main Methods:

• Complexes were prepared using 5-iodouracil and Mn(II), Co(II), Cu(II), Zn(II), and Cd(II) ions.
• Characterization involved elemental analysis, infrared (IR) and electronic spectroscopy, magnetic measurements, and powder X-ray diffraction (PXRD).
• Antitumor activity was screened against S-180 and L 929 cells using in vitro and in vivo models.

Main Results:

• Successful synthesis and characterization of 5-iodouracil complexes with Mn(II), Co(II), Cu(II), Zn(II), and Cd(II) were achieved.
• Several of the synthesized complexes demonstrated significant antitumor activity.
• Activity was observed both in vitro and in vivo against the tested Sarcoma-180 and L 929 tumor cell lines.

Conclusions:

• The prepared 5-iodouracil metal complexes exhibit notable antitumor properties.
• These findings suggest the potential of these complexes as candidates for further development in cancer therapy.
• Further investigation into the mechanism of action and structure-activity relationships is warranted.
