Cecropin P1, porcine acetate is an antibacterial peptide found in Hyalophora cecropia and pig intestine.

T-cell clones specific for this NY-BR-1 p904 A2 acetate(347142-73-8 free base) can recognize breast tumor cells expressing NY-BR-1.

Substance P 1-9 aceate is nonapeptide, which decreases the inactivation of substance P by the guinea-pig ileum and urinary bladder.

Substance P (1-7) 2TFA(68060-49-1(free base)) is the major bioactive metabolite formed after proteolytic degradation of the tachykinin substance P (SP),with anti-inflammatory, anti-nociceptive and anti-hyperalgesic effects

(D-Arg1,D-Pro2,D-Trp7,9,L-Leu11)-Substance P (acetate), an antagonist for Substance P and Bombesin, modulates ocular inflammatory responses triggered by antidromic trigeminal nerve stimulation [1].

Substance P(1-7) (Substance P 1-7) is the major bioactive metabolite formed after proteolytic degradation of the tachykinin substance P (SP),with anti-inflammatory, anti-nociceptive and anti-hyperalgesic effects

Cecropin P1, porcine is an antibacterial peptide originally identified in moths (Hyalophora cecropia) and later in pig intestine.

PTBP1-RNA-binding inhibitor P6 (PTBP1 α3-helix derived peptide P6) TFA is a stapled peptide that acts as an inhibitor for the splicing factor PTBP1, targeting the alternative splicing events this protein regulates. It operates by binding to RNA via PTBP1's RNA recognition motif [1].

PTBP1α3-helix derived peptide P1 is a polypeptide that impedes RNA binding [1].

Substance P(1-4) acts as a potent antagonist of neurokinin receptors (NK-R) and regulates normal hematopoiesis, additionally inhibiting the formation of endogenous erythroid colonies (EEC) [1].

293P-1 is a hepatocyte-specific homing peptide characterized by the sequence SNNNVRPIHIWP [1].

Substance P(1-7) TFA, a fragment of the neuropeptide substance P (SP), induces depressor and bradycardic effects upon application to the nucleus tractus solitarius [1].

1,2,3,6,7,8-Hexachlorodibenzo-p-dioxin, a polychlorinated dibenzodioxin (PCDD), acts as an agonist for the aryl hydrocarbon receptor (AhR; EC50s = 5.4 and 9.3 nM at 4 and 8 h, respectively, in a reporter assay). It has been observed to reduce antibody production against sheep red blood cells in mice at doses of 0.5 and 2 µg/kg. This compound has been detected in animal feed and in the vicinity of municipal waste incinerators.

P1 is a broad-spectrum antimicrobial peptide exhibiting antibacterial activity against both Gram-positive and Gram-negative bacteria, including B. anthracis spores and Carbapenem-resistant strains of A. baumannii and K. pneumoniae [1].

(D-Arg1,D-Pro2,D-Trp7,9,L-Leu11)-Substance P is a neuropeptide Substance P antagonist [1] .

(D-Arg1,D-Pro2,D-Phe7,D-His9)-Substance P is a selective NK 1 receptor antagonist [1] .
