Cortistatin-29 (rat) (trifluoroacetate salt) Chemical Properties,Usage,Production
Description
Cortistatin-29 is a neuropeptide that is structurally similar to somatostatin-28. It is produced by cleavage of preprocortistatin to procortistatin, which is cleaved at dibasic amino acids to form cortistatin-29 and cortistatin-14 as well as other partial cleavage products. Cortistatin mRNA is expressed in the human brain and in interneurons of the rat hippocampus and cerebral cortex. Cortistatin-29 binds to somatostatin (SST) receptors with IC50 values of 2.8, 7.1, 0.2, 3, and 13.7 nM for SST1-5, respectively. Cortistatin-29 is found at similar levels as cortistatin-14 in mouse AtT20 cells but is secreted at a lower level. Cortistatin-29 corresponds to residues 85-112 of the rat peptide sequence.
Uses
Cortistatin-29 is a neuropeptide. Cortistatin-29 alleviates neuropathic pain. Cortistatin-29 binds all somatostatin (SS) receptor subtypes with high affinity and shows IC50 values of 2.8 nM, 7.1 nM, 0.2 nM, 3.0 nM, 13.7 nM for SSTR1, SSTR2, SSTR3, SSTR4, SSTR5, respectively. Cortistatin-29 shows anti-fibrotic effects[1][2][3][4].
in vivo
Cortistatin 29 (1-2 μg) alleviates chronic neuropathic pain in mouse[1].
Cortistatin 29 (1 nmol/mouse; i.p.; three times weekly) shows anti-fibrotic effects in mouse[4].
| Animal Model: | 20-24 g body weight, 8-12 weeks-old mice[1] |
| Dosage: | 1 μg in 20 μL for s.c.; 2 μg in 200 μL for i.p.; 20 ng in 10 μL for i.t. |
| Administration: | Every other day for 12 days |
| Result: | Ameliorated hyperalgesia and allodynia, regulated the nerve damageinduced hypersensitization of primary nociceptors, inhibited neuroinflammatory responses, and enhanced the production of neurotrophic factors both at the peripheral and central levels. |
IC 50
SSTR1: 2.8 nM (IC50); SSTR2: 7.1 nM (IC50); SSTR3: 0.2 nM (IC50); SSTR4: 3.0 nM (IC50); SSTR5: 13.7 nM (IC50)
