WEHL-04 is an intermediate used to prepare (isoquinolinylsulfonyl)benzoic acids as inhibitors of type 5 71-β-hydroxysteroid dehydrogenase AKR1C3. It is also used in the synthesis of 2-aminooctahydrocyclopentalene-3a-carboxamides as potent CCR2 antagonists.

[D-Pro4,D-Trp7,9,Nle11] Substance P (4-11) is a potent neurokinin NK1 antagonist. [D-Pro4,D-Trp7,9,Nle11] Substance P (4-11) inhibits the effects of gold-protein-substance P (GPSP) and substance P (SP).

Diaminopimelic acid or DAPA is a lysine-like amino acid derivative that is a key component of the bacterial cell wall. DAPA is incorporated or integrated into peptidoglycan of gram negative bacteria and is the attachment point for Braun's lipoprotein (BLP or Murein Lipoprotein). BLP is found in gram-negative cell walls and is one of the most abundant membrane proteins.
