Cyclotraxin B acetate is an antagonist of TrkB receptors; inhibits BDNF-induced TrkB activity (IC50 = 0.30 nM). Allosterically alters TrkB receptor conformation but does not alter BDNF binding. Prevents BDNF-induced cold allodynia in mice. Also shown to exhibit putative anxiolytic properties in mice.

Relaxin H3 (human) is a relaxin peptide that exhibits antifibrotic effects through activation of RXFP1 [1].

Relaxin C-peptide, as a synthetic 14-amino acid peptide found in human decidua & placenta, can represent a partial sequence of human relaxin connecting peptide.

Antagonist of TrkB receptors; inhibits BDNF-induced TrkB activity (IC50 = 0.30 nM). Allosterically alters TrkB receptor conformation but does not alter BDNF binding. Prevents BDNF-induced cold allodynia in mice. Also shown to exhibit putative anxiolytic p

Pardaxin P5, an antimicrobial peptide, inhibits Escherichia coli at a minimum inhibitory concentration (MIC) of 13 μM [1].

Cyclotraxin B TFA, a cyclic peptide, serves as a highly potent and selective non-competitive inhibitor of TrkB, effectively impeding BDNF-triggered TrkB activity without altering BDNF binding affinity, evidenced by an IC50 of 0.30 nM. It is capable of crossing the blood-brain barrier, demonstrating analgesic and anxiolytic-like behavioral effects [1] [2] [3].
