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.

(D-Ala2)-GRF (1-29) amide (human) is a superagonist of GRF, exhibiting extremely high GH-releasing activity about 50 times that of GRF (1-29) in both pigs and rats.

(2-Hydroxypropyl)-β-cyclodextrin is a widely used drug delivery vehicle to improve stability and bioavailability.
