chelating effects of the C3 and C5 substituents. Bulky groups interfere with ring-to-ring hydrophobic interaction with tyrosine (Tyr)4311 and limit the efficiency of increasing the length of the hydrocarbon chain of esters at the 3- and 5-positions of the DHP ring as an approach to increasing the activity. The presence of a chelating substituent on the phenyl ring at the 4-position of the DHP ring ensures
