WebSome alkylating agents are active under conditions present in cells; and the same mechanism that makes them toxic allows them to be used as anti-cancer drugs. They … WebAlkylating agents are compounds that work by adding an alkyl group to the guanine base of the DNA molecule, preventing the strands of the double helix from linking as they should. This causes breakage of the DNA strands, affecting the ability of the cancer cell to multiply. Eventually, the cancer cell dies.
Balancing repair and tolerance of DNA damage caused by alkylating agents
WebHow do alkylating agents carry out DNA repair? Alkylating agent-induced damage to DNA is sensed and repaired by different cellular mechanisms, including direct repair by the AlkB homologue (ALKBH) family and O 6-methylguanine-DNA methyltransferase (MGMT) proteins or by pathways such as base excision repair (BER), mismatch repair (MMR), homologous … WebThese factors can cause damage to the DNA structure, ultimately leading to the destruction of the DNA molecule. One of the primary causes of DNA damage is exposure to ultraviolet radiation from the sun. ... intercalating agents, and oxidizing agents can also destroy DNA. The alkylating agents can alkylate DNA bases, leading to strand breakage ... lightly在线编程官网

WebMar 31, 2024 · DNA bases can be damaged by: (1) oxidative processes, (2) alkylation of bases, (3) base loss caused by the hydrolysis of bases, (4) bulky adduct formation, (5) … WebA second mechanism by which alkylating agents cause DNA damage is the formation of cross-bridges, bonds between atoms in the DNA (pink linkages below). In this process, … WebAlkylating agents are compounds that work by adding an alkyl group to the guanine base of the DNA molecule, preventing the strands of the double helix from linking as they should. … lightly-lemon flavoured firm light sponge
