Undecanedicarboxylic acid is an unusual odd-numbered dicarboxylic acid that appears in the urines of children with neonatal adrenoleukodystrophy and Zellweger syndrome as an additional marker of these peroxisomal disorders.

PTD-p65-P1 Peptide is a nuclear transcription factor NF-kappaB inhibitor, composed of a membrane-translocating peptide sequence generated from antennapedia (PTD) conjugated with p65-P1, which selectively inhibits activation induced by various inflammatory stimuli. PTD-p65-P1 suppressed NF-kappaB activation induced by lipopolysaccharide, interleukin-1, okadaic acid, phorbol 12-myristate 13-acetate, H(2)O(2), and cigarette smoke condensate as well as that induced by TNF.

α-MSH free acid (α-Melanocyte-Stimulating Hormone free acid) is an MC3R and MC4R agonist with EC50s of 0.16 nM and 5.6 nM, respectively. α-MSH free acid activates cAMP generation at MC3R and MC4R.
