CISPLATIN Synthesis, SAR, MCQ,Structure,Chemical Properties and Therapeutic Uses


IUPAC nomenclature



Cisplatin  falls under the category of Antineoplastic cytotoxic drug. [1]

Physiochemical Properties

1 Molecular weight 300 g/mol
2 Appearance Platinol vials contains cisplatin as a lyophilized powder form.
3 Melting point 270°C
4 Solubility Solubility in water is 2.53g/L
5 Presence of ring No ring structure present

Mechanism of Action                                                                                                                       

i. It introduces the alkyl groups to the DNA. When repair enzymes tries to remove the alkylaed fragments, they fragment the DNA.

ii. It binds with DNA and produces cross-linkages.

iii. It induces mispairing of the DNA causes mutations in the cells.[2]

Structural Activity Relationship

  • Cytotoxicity of oxiplatin is also greater than cisplatin.
  • Organic functionalities of nonleaving groups coordinated to platinum are critical for selective uptake by OTCs. [3]

Methods of Synthesis

i. Potassium tetrachloroplatinate is reacted with excess of potassium iodide.

ii. The tetraiodide so formed is reacted with ammonia to form K2[PtI2(NH3)2], a yellow compound.

iii. The insoluble silver iodide is precipitated as the yellow compound is treated with silver nitrate in water.

iv. Addition of the potassium chloride gives the final product.
