GPR35 agonist 4 (compound 10) demonstrates high potency as a GPR35 agonist with a pEC50 of 5.86, effective on both human and rat GPR35; mutation of arginine at position 3.36 results in loss of its agonist function on GPR35 [1].

3β-OH-7-Oxocholenic acid is a bile acid.1 It is also a metabolite of 7β-hydroxy cholesterol in rats. Conjugated forms of 3β-OH-7-oxocholenic acid have been found in the urine of patients with Neimann-Pick disease type C.2,3 |1. Norii, T., Yamaga, N., and Yamasaki, K.

Amustaline (S-303) dihydrochloride is a nucleic acid-targeted alkylator recognized for its efficacy as a pathogen inactivation agent in blood components containing red blood cells. This compound comprises three key elements: an acridine anchor (a non-covalently bonding intercalator targeting nucleic acids), an effector (a bis-alkylator group that interacts with nucleophiles), and a linker (a flexible carbon chain with a labile ester bond, hydrolyzing at neutral pH to non-reactive products).

Peptide M acetate is a synthetic amino acid (18 amino acids in length which correspond to the amino acid positions 303-322 of bovine S-antigen: DTNLASSTIIKEGIDKTV). Peptide M acetate is capable of inducing experimental autoimmune uveitis in monkeys and Hartley guinea pigs as well as Lewis rats.
