Description: Peptide to [D-Arg1, D-Trp5, 7, 9, Leu11]-Substance P Form: Lyophilized powder CAS Number : 122481-75-8Molecular Formula : C81H110N20O12Molecular Weight : 1555.91Purity : > 95%Chemical Structure : D-Arg-Pro-Lys-Pro-D-Trp-Gln-D-Trp-Phe-D-Trp-Leu-Leu-NH2Application : This substance P analog is a very potent broad-spectrum neuropeptide inhibitor for small cell lung cancer (SCLC) cell growth in vitro (IC₅₀ = 5 µM). Moreover it potently inhibited signal transduction pathways in vitro and significantly delayed the growth of an SCLC xenograft in vivo. It could therefore be of therapeutic value in SCLC.Storage/Stability : Shipped at 4°C. Store at -20°C for one year.
