O=C(NCC1CCCCC1)[C@@H]1CN(C(=O)CCl)CCN1S(=O)(=O)c1ccsc1
The design of this compound comes from a very potent fragment MAT-POS-ee51dedd2. Crystallography analysis would suggest that building a group from one of the piperazine carbons may provide a bridge to the pocket where several of the 3-aminopyridine like fragments are bound (fragment linking).
