Compound 1 is an antagonist, meaning answer choice B is correct.Ģ) The number of stereoisomers is equal to 2 n where n = number of chiral centers. – Catalysts increase the rate of a reaction, but in the case of Compound 1, the reaction is being stopped, not sped up. This means that Compound 1 is not a placebo. If Compound 1 is being used to treat HIV infection, it should have some biological mechanism for treatment-and we know that it does because it binds the HIV protease. – A placebo serves as a negative control it is given to determine the amount of the effect that is caused by the therapeutic value of someone believing they are being treated, but does not have a clear biological mechanism that would affect the results. – An antagonist would inactivate the enzyme which, as noted above, seems to be the effect of Compound 1. An agonist would activate the enzyme, not inhibit it. However, it prevents the enzyme from performing its function which we know because it’s used to treat HIV, not amplify the infection. – The passage says that Compound 1 is a “ transition state analog” for the HIV protease enzyme, which means that it mimics the product of substrate binding.
