- A chemically modified guanidino group is present in cimetidine (Tagamet), a widely prescribed drug for the control of gastric acidity and peptic ulcers. Cimetidine reduces gastric acid secretion by inhibiting the interaction of histamine with gastric H2 receptors. In the development of this drug, a cyano group was added to the substituted guanidino group to alter its basicity. Do you expect this modified guanidino group to be more basic or less basic than the guanidino group of arginine? Explain.arrow_forwarda.

What disulfide is formed from oxidation of (S)-penicillamine?arrow_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. See page 14 of the lecture notes for Lecture 9 How ADME affects preclinical Drug Design February 24, 2023, where I have shown the mechanism for this addition and give the…arrow_forward
- Prostaglandins are a class of eicosanoids, fatty acid derivatives with a variety of extremely potent actions on vertebrate tissues. They are responsible for producing fever and inflammation and its associated pain. Prostaglandins are derived from the 20- carbon fatty acid arachidonic acid in a reaction catalyzed by the enzyme prostaglandin endoperoxide synthase. This enzyme, a cyclooxygenase, uses oxygen to convert arachidonic acid to PGG2, the immediate precursor of many different prostaglandins. Rate of formation of PGG2 with 10 mg/ml ibuprofen (mM/min) Arachidonic acid (mM) Rate of formation of PGG2 (mM/min) 0.190 12.3 0.228 13.9 0.342 17.5 0.570 1.33 22.2 28.8 7.71 8.88 11.9 16.3 24.0 The kinetic data given in the table are for the reaction catalyzed by a mutant of prostaglandin endoperoxide synthase.
