Some replacements of cyclohexylethyl substituent. If I get everything correctly that pocket is rather nonpolar and the only polar interactions possible are with Ser46 and Thr25. Some amides like ALP-POS-c59291d4-2 seem to interact with the former.
Structures with two stereocentres are meant as trans- isomers
