Interpretation:
Mechanisms for the three steps involved in the trapping of β- lactamase by tazobactum such as a) the reaction of the hydroxyl group on the β- lactamase to open the β- lactum ring of tazobactum b) The opening of the sulfur-containing ring in tazobactum to give an acyclic imine intermediate c) Cyclization of the imine intermediate to yield trapped β- lactamase product are to be proposed.
Concept introduction:
Three steps are involved in the conversion required. i ) Nucleophilic attack of β- lactamase on tazobactum to open the β- lactum ring ii) Formation of an imine intermediate by opening of the sulfur-containing ring in tazobactum iii) Cyclization to yield the trapped β- lactamase. All the three reactions involve the attack of nucleophiles.

- Acetylcholine (ACh) is an important signaling molecule in the nervous system. After it transmits a signal, ACh is broken down by the enzyme acetylcholinesterase (AChE) in a reaction known as ACh hydrolysis. Which of the following best describes the effect AChE has on the hydrolysis of ACh? Group of answer choices AChE decreases the activation energy of ACh hydrolysis, increasing the rate of this reaction AChE increases the activiation energy of ACh hydrolysis, increasing its rate AChE decreases the activation energy of ACh hydrolysis, decreasing the rate of this reaction AChE increases the activiation energy of ACh hydrolysis, increasing the rate of this reactionarrow_forwardIdentify the organic functional group and reaction type for the following reaction.

- Paroxetine (Paxil) is an antidepressant that is a member of a family of drugs known as Selective Serotonin Reuptake Inhibitors (SSRIS). This family of drugs also includes fluoxetine (Prozac) and sertraline (Zoloft). SSRIS work by inhibiting the reuptake of the neurotransmitter serotonin in the synapses of the central nervous system follow- ing release of serotonin during excitation of individual nerve cells. Between firings, the serotonin is taken back up by a nerve cell in preparation for firing again. Inhibition of reuptake has the effect of increasing the time serotonin molecules remain in the syn- apses following excitation, leading to a therapeutic effect. In one synthesis of parox- etine, the following reagents are used. Draw the structures of synthetic intermediates A and B.

- Draw the products of the acetone + LDA/THF: (1) slow addition of ethyl acetate; (2) HClarrow_forwardThe addition of a nucleophilic group like a thiol (-SH), or an unprotonated amino group (-NH₂) to an a,ß-unsaturated ketone is important for understanding how NAPQI reacts with glutathione, N-acetylcysteine, or protein amino acid side chains containing -SH or -NH2 groups. In this problem we will add mercaptoethanol to p-benzoquinone. p-Benzoquinone will be a simple model of NAPQI. +H H a single uncharged addition product This reaction will proceed in steps. First the H-S-R will add to the unsaturated ketone to give a charged addition product. Next, a simple proton transfer will form an uncharged adduct in which the 6-membered ring contains one carbonyl and a second enolic hydroxyl. The keto form next will tautomerize to its more stable enol form, and in doing so the 6-membered ring becomes aromatic with 6-π electrons.
