2.7 Now that you have figured out the reaction mechanism, let's explore the action mechanism of thefollowing drug. Notice that this molecule is composed of two chloroethylamine groups and therefore canreact with two different nucleophiles. Complete the following reaction mechanism.R-NClCL+R'-NH₂R"-NH₂The above reaction is responsible for the activity of the drug. Because of its ability to react with twonucleophiles, the drug can create a bridge between two biologically active molecules and disrupt theiractivity. This process is known as 'cross-linking'. For example, it can react with two DNA strands andprevent 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.

What would be the characteristics of a transitionstate analog for the chymotrypsin reaction?
An inhibitor that specifically labels chymotrypsin at histidine 57 is Ntosylamido-l-phenylethyl chloromethyl ketone. How would you modify the structure of this inhibitor to label the active site of trypsin?
Enalapril is an anti-hypertension "prodrug" (i.e, a drug precursor) that is inactive until the ethyl ester (arrow in figure) is hydrolyzed by esterases present in blood plasma. The active drug is the dicarboxylic acid ("enalaprilat") that results from this hydrolysis reaction. (a) Enalapril is administered in pill form, but enalaprilat must be administered intravenously. Why do you suppose enalapril works as a pill, but enalaprilat does not? EtOOC -NH CH3 HOOC Enalapril (b) Enalaprilat is a competitive inhibitor of the angiotensin-converting enzyme (ACE), which cleaves the blood-pressure regulating peptide angiotensin. ACE has a KM = 12 µM for angiotensin, which is present in plasma at a concentration of 75 µM. When enalaprilat is present at 2.4 nM, the activity of ACE in plasma is 10% of its uninhib- ited activity. What is the value of K; for enalaprilat?
Dehalogenase enzymes catalyze the clevage of C-X bonds. One such dehalogenase catalyzes the following reaction.
