Cisplatin molecules bind to nitrogen atoms

Web1. Cisplatin (Pt(NH3)2Cl2) enters the body mainly through active transport 2. When in the nucleus, it bonds between two guanine in DNA 3. Cisplatin (Pt(NH3)2Cl2) loses two chlorine atoms to gain the nitrogen atoms on … WebJan 1, 2024 · The adducts occur through a coordinated covalent bonding between the platinum atom of cisplatin and two nitrogen atoms (N7s) of two purine bases (mostly adjacent guanine–guanine) [6]. As a result, the drug can also cause collateral cell damage because the adducts form equally well in cancerous and normal cells.

WebCisplatin is a platinum-based agent whose nephrotoxicity is thought related to the chloride in the cis position. Cisplatin gains entry into tubular cells via uptake by the OCT-2 … WebWell atoms like cesium or francium have very small electronegativity values. And so pairing them with the electronegative atoms commonly associated with hydrogen bonding (nitrogen, oxygen, and fluorine) will have a large enough electronegativity difference that their bonding is no longer considered polar covalent, but rather ionic. flutter opencv-python https://kabpromos.com
