2.7 Now that you have figured out the reaction mechanism, let's explore the action mechanism of the following drug. Notice that this molecule is composed of two chloroethylamine groups and therefore can react with two different nucleophiles. Complete the following reaction mechanism. R-N CL + R'-NH₂ R"-NH₂ The above reaction is responsible for the activity of the drug. Because of its ability to react with two nucleophiles, the drug can create a bridge between two biologically active molecules and disrupt their activity. This process is known as 'cross-linking'. For example, it can react with two DNA strands and prevent their separation during replication. This will cause cytotoxicity and cell death. 2.8 Draw a scheme/cartoon to represent the general idea of chemical cross-linking described above.

2.7 Now that you have figured out the reaction mechanism, let's explore the action mechanism of the
following drug. Notice that this molecule is composed of two chloroethylamine groups and therefore can
react with two different nucleophiles. Complete the following reaction mechanism.
R-N
Cl
CL
+
R'-NH₂
R"-NH₂
The above reaction is responsible for the activity of the drug. Because of its ability to react with two
nucleophiles, the drug can create a bridge between two biologically active molecules and disrupt their
activity. This process is known as 'cross-linking'. For example, it can react with two DNA strands and
prevent their separation during replication. This will cause cytotoxicity and cell death.
