      Carmustine is a cell-cycle phase nonspecific alkylating antineoplastic agent.; Target: DNA alkylator/crosslinker; Carmustine causes cross-links in DNA and RNA, leading to the inhibition of DNA synthesis, RNA production and RNA translation (protein synthesis). MedChem Express HY-13585
      Carmustine is a cell-cycle phase nonspecific alkylating antineoplastic agent.;Target: DNA alkylator/crosslinkerCarmustine causes cross-links in DNA and RNA, leading to the inhibition of DNA synthesis, RNA production and RNA translation (protein synthesis). Carmustine also binds to and modifies (carbamoylates) glutathione reductase. This leads to cell death. Carmustine (1,3-bis (2-chloroethyl)-1-nitrosourea) is a nitrosourea alkylating agent that exerts its antitumor effect by akylating DNA and RNA. The development of carmustine wafers (Gliadel((R)) Wafer) as a method for controlled released delivery of carmustine from biodegradable polymer wafers enhances the therapeutic ratio by fully containing the drug within the confines of the brain tumor environment while minimizing systemic toxicities [1, 2].
