CTOP

CAT#	R1808
Chemical Structure
CAS	103429-31-8
Synonyms/Alias	CTOP, (Tyr3,Orn5,Pen7)-Octreotate amide
M.F/Formula	C50H67N11O11S2
M.W/Mr.	1062.26
Sequence	One Letter Code: FCYW{Orn}T{Pen}T-NH2 (Disulfide bridge:Cys2-Pen7) Three Letter Code: Phe-Cys-Tyr-Trp-{Orn}-Thr-{Pen}-Thr-NH2 (Disulfide bridge:Cys2-Pen7)
Biological Activity	Potent and selective μ opioid receptor antagonist (Ki values are 0.96 and >10,000 nM for μ and δ receptors respectively). Causes behavioral effects on central administration in vivo. Also increases K+ currents in rat locus ceruleus neurons in vitro via a μ receptor independent mechanism.
