pheromone

α-Factor Mating Pheromone, yeast acetate (Mating Factor α acetate) is a peptide of 13 amino acids secreted by Saccharomyces cerevisiae α cells.

Sex Pheromone Inhibitor iPD1 is a compound that functions as an inhibitor of the sex pheromone cPD1 [1].

The alpha factor pheromone arrests yeast in the G1 phase of their cell cycle. Alpha Factor Mating Pheromone induces the expression of mating genes, changes in nuclear architecture, and polarzes growth toward the mating partner.

Alpha factor mating pheromone is a peptide of 13 amino acids secreted by Saccharomyces cerevisiae α cells.

Gly-Phe-Arg acetate is a superpotent synthetic tripeptide mimics of the mud-crab pumping pheromone.

Siamycin I is a tricyclic peptide originally isolated from Streptomyces and has antiviral and antibacterial activities. It is active against laboratory strains and clinical isolates of HIV-1 (ED50s = 0.05-0.45 and 0.89-5.7 μM, respectively), as well as the CBL-20 strain of HIV-2 (ED50 = 0.45 μM), in vitro. Siamycin I inhibits HIV-induced fusion of C8166 T cells with HIV-1-infected CEM-SS cells with an ED50 value of 0.08 μM. It is also active against B. subtilis, M. luteus, and S. aureus (MICs = 1.6-6.3 μg/ml). Siamycin I inhibits autophosphorylation of the E. faecalis quorum sensing kinase FsrC induced by gelatinase biosynthesis-activating pheromone (GBAP).

COB1 pheromone, a bacterial sex pheromone, effectively inhibits the multidrug-resistant Enterococcus faecalis V583 [1].

Pheromonotropin (Pseudaletia separata) (Pss-PT), a C-terminal pentapeptide FXPRL-amide pheromone of the armyworm (Pseudaletia separata), is a member of the PK PBAN family that induces sex pheromone production in moths, mediates feeding through intestinal muscle contraction, influences development processes such as embryonic and pupal diapause and pupation, and enhances defense mechanisms against predators [1].

Gly-Gly-Arg, a tripeptide and pumping pheromone, is released from hatching eggs, stimulating pleopod pumping activity in subtidal crustaceans at a threshold concentration of 10 nM and eliciting a maximum response rate of 58.3%. Additionally, this compound plays a role in controlling larval release in these organisms [1].

Gly-Phe-Arg is a highly potent synthetic tripeptide that mimics the pumping pheromone of the mud-crab.

AT1R epitope (iCF10) is a heptapeptide and acts as a competitive inhibitor of cCF10, a peptide pheromone.
